The World Counts • Impact through Awareness

The world counts impact through awareness, 45 arrivals every second.

There are over 1.4 billion tourists arriving at their destination every year. That’s 45 arrivals every single second.

Exponential growth of tourism

In 1950 there were 25 million international tourist arrivals, in 1970 the number was 166 million, and by 1990 it had grown to 435 million. From 1990 to 2018 numbers more than tripled reaching 1.442 billion. By 2030, 1.8 billion tourist arrivals are projected.

Negative environmental impacts of tourism

The negative environmental impacts of tourism are substantial. They include the depletion of local natural resources as well as pollution and waste problems. Tourism often puts pressure on natural resources through over-consumption, often in places where resources are already scarce.

Tourism puts enormous stress on local land use, and can lead to soil erosion, increased pollution, natural habitat loss, and more pressure on endangered species. These effects can gradually destroy the environmental resources on which tourism itself depends.

Tourism often leads to overuse of water

An average golf course in a tropical country, for example, uses as much water as 60,000 rural villagers. It also uses 1500 kilos of chemical fertilizers, pesticides and herbicides per year.

Tourism and climate change

Tourism contributes to more than 5 percent of global greenhouse gas emissions, with transportation accounting for 90 percent of this.

By 2030, a 25% increase in CO2-emissions from tourism compared to 2016 is expected. From 1,597 million tons to 1,998 million tons.

tourism harmful effects

  • INTELLIGENT TRAVEL

Is Tourism Destroying the World?

Travel is transforming the world, and not always for the better. Though it’s an uncomfortable reality (who doesn’t like to travel?), it’s something award-winning journalist Elizabeth Becker   devoted five years of her life to investigating. The result is Overbooked: The Exploding Business of Travel and Tourism .

I caught up with the author to get the inside scoop on the book, what prompted her to write it, and what she learned along the way, and this is what she had to say.

Leslie Trew Magraw: You made a name for yourself as a war correspondent covering Cambodia for The Washington Post . What prompted you to write this book?

Elizabeth Becker: My profession has been to understand world events.   I reported from Asia and Europe [for the Post ] and later was the senior foreign editor at NPR.   At The New York Times ,   I became the international economics correspondent in 2002, and that is when I began noticing the explosion of tourism and how much countries rich and poor were coming to rely on it.

But tourism isn’t treated as a serious business or economic force. Travel sections are all about the best vacations. So I used a fellowship at Harvard to begin my research and then wrote this book to point out what seemed so obvious: Tourism is among the biggest global industries and, as such, has tremendous impacts—environmental, cultural, economic—that have to be acknowledged and addressed.

Amazon named "Overbooked" one of the ten best books of the month. (Cover courtesy Simon & Schuster)

Which country can you point to as a model for sustainable tourism?

One of the more ambitious is France , which is aiming for sustainability in the whole country. The key, I think, is that the French never fully bought in to the modern obsession with tourist overdevelopment. They have been nurturing their own culture and landscape, cities, and villages for decades. Since they have tied their economy to tourism, they have applied a   precise and country-wide approach that mostly works.

All relevant ministries are involved, including culture, commerce, agriculture, sports, and transportation. Planning is bottom up, beginning with locals at destinations who decide what they want to promote and how they want to improve. The French obsession with protecting their culture—some would call it arrogance—has worked in their favor. The planning and bureaucracy required to make this work would try the patience of many governments.

Now, even though the country is smaller than the state of Texas, France is the most popular destination in the world. Tourism officials told me one of their biggest worries is becoming victims of their success: too many foreigners buying second homes or retirement homes in French villages and Parisian neighborhoods, which could tip the balance and undermine that sustainable and widely admired French way of life.

Many destinations are making impressive changes. Philanthropists are helping African game parks find their footing. I was lucky to see how Paul Allen , for instance, is helping in Zambia .

Which country is doing it all wrong?

Cambodia has made some bad choices in tourism. It is blessed with the magnificent temples of Angkor , glorious beaches in the south, cities with charming overlay of the French colonial heritage, and   a rural landscape of sugar palms, rice paddies, and houses on stilts.

Yet, rather than protect these gems, the government has allowed rapacious tourism to threaten the very attractions that bring tourists. Tourism is seen as a cash cow.

Some of the capital’s most stunning historic buildings are being razed to build look-alike modern hotels.   In Angkor, a thicket of new hotels has outpaced infrastructure and is draining the water table so badly the temples are sinking—and profits from tourism do not reach the common people, who are now among the poorest in the country.

In addition, Cambodia has become synonymous with sex tourism that exploits young girls and boys. The latest wrinkle is to encourage tourists on the “genocide trail” to see the killing fields and execution centers from the Khmer Rouge era.

With more than a billion people traveling each year, how can we see the world without destroying it?

That is the essential question.   Countries are figuring out how to protect their destinations in quiet, non-offensive ways. They control the number of hotel beds, the number of flights to and from a country, the number of tour buses allowed. Some have “sacrifice zones,” where tourists are allowed to flood one section of beachfront, for example, while the rest is protected as a wildlife preserve or [reserved] for locals. Most countries are heavily promoting off-season travel as the most obvious way to control crowds.

Countries are also putting more muscle into regulations [governing] pollution. The toughest problem is breaking the habit of politicians being too close to the industry to the detriment of their country. Money talks in tourism as in any other big business. Luxury chains wanting a store near a major tourist attraction will pay high rents to push out locals. Officials fail to enforce rules against phony “authentic” souvenirs.

One of the worst offenders are the supersize cruise ships that swarm localities, straining local services and sites and giving back little in return.

What do you think will be the biggest challenge for 21st-century travelers?

Avoiding “drive-by tourism.” This is a phrase coined by Paul Bennett of   Context Travel ,   referring to the growing habit of people visiting a destination for a few hours—maybe a few days—and seeing only a blur of sights with little appreciation for the country, culture, or people.

One of the eureka moments in my five years of research was reading old guidebooks in the   Library of Congress.

The Baedeker Guides were written in consultation with historians and archaeologists who presumed the tourists wanted to immerse themselves in a country. They included a short dictionary of the language of the country and, only at the very end, short lists of hotels and restaurants.

Today it is the reverse: Guides have short paragraphs about history, culture, and politics and long lists of where to eat and sleep.

  • Nat Geo Expeditions

My advice is to first be a tourist where you live. Explore the museums, the farms, the churches, the night life, the historic monuments—and then read up on local politics and history.

If you’re interested in volunteering overseas, first volunteer at home. Then when you’re planning your next trip abroad, use that experience as a template and study up on the destination you’re about to visit.

Don’t forget to try to learn something of the local language. It is a gift.

Q: Are there any tourism trends that give you hope for the future of travel?

A: People are again recognizing that travel is a privilege. Responsible tourism in its various forms—volunteer tourism, adventure tourism, slow tourism (where people take their time), agro-tourism (where visitors live and work on a farm), ecotourism , geotourism—all speak to tourists’ desire to respect the places they visit and the people they meet.   I think people are also recognizing that bargain travel has hidden expenses and dangers.

Costa Rica was an eye-opener for me; it deserves its reputation as a leader in responsible tourism that nurtures nature and society.

Finally, several groups including the United Nations World Tourism Organization have put together a global sustainable tourism council with a certification program to show tourists which places are genuinely making the effort.

What Is Overtourism and Why Is It Such a Big Problem?

Travel destinations are becoming too popular for their own good.

Can Overtourism Be Reversed?

  • Machu Picchu, Peru
  • Maya Bay, Thailand
  • Mount Everest
  • Venice, Italy

Overtourism happens when the number of tourists or the management of the tourism industry in a destination or attraction becomes unsustainable. When there are too many visitors, the quality of life for the local community can diminish, the surrounding natural environment can be negatively affected, and the quality of the tourists' experience can decline.

According to the World Tourism Organization, there were 1.5 billion international tourist arrivals worldwide in 2019, a 4% increase from the previous year. International tourist arrivals have continued to outpace the global economy, and the number of destinations earning $1 billion or more from international tourism has doubled since 1998. Tourism is growing, and some places just can’t seem to keep up.

Overtourism Definition

Although the term itself didn’t appear until around 2017 (a writer at media company Skift is often credited for first coining it in the summer of 2016), the problem of overtourism is hardly a new one. The "irritation index," known as Irridex, has examined the change between resident attitudes towards tourists throughout different stages of tourism development since 1975. According to the Galapagos Conservation Trust, tourist satisfaction rankings have been steadily decreasing since 1990 due to overcrowding; the official guidelines for visitor numbers set in 1968 when the Galapagos Island National Park first opened had risen 10-fold by 2015.

The United Nations World Tourism Organization has defined overtourism as "the impact of tourism on a destination, or parts thereof, that excessively influences perceived quality of life of citizens and/or quality of visitors experiences in a negative way." Environmental consequences are a symptom of overtourism, and the recent boost in awareness surrounding the buzzword is simply because there are more destinations around the world experiencing it.

As for what exactly is to blame for overtourism, there are numerous factors at play. Cheaper flights are making travel more accessible, cruise ships are dropping thousands of tourists off to spend several hours at a destination without spending money locally, social media is inspiring users to get that perfect selfie at travel hotspots ... the list goes on and on.

Studies even show that television and movies can impact a place’s desirability. Episodes of Game of Thrones filmed in the historical Croatian town of Dubrovnik corresponded to 5,000 additional tourism overnights per month (59,000 per year) after they aired. Most of these tourists stayed under three days, packing the Old Town walls with day tours that increased pollution and put new strains on the 13th-century infrastructure.

Like so many others, the travel industry has focused too much on growth and not enough on environmental impacts. Rising awareness of overtourism consequences has inspired local and national governments to protect their commodities through sustainable tourism practices and ensure that tourism behavior isn’t damaging—or even better, can be beneficial—to the local environment.

The Consequences of Overtourism

Needless to say, the environmental consequences of overtourism can be catastrophic. Accumulation of trash, air pollution, noise, and light pollution can disrupt natural habitats or breeding patterns (baby sea turtles, for example, can become disorientated by artificial lighting when they hatch ). Both natural and local resources, like water, will degrade as destinations or attractions struggle to accommodate numbers they simply weren’t built to handle. And even as these spots begin increasing tourism development to keep up, they may turn to unsustainable land practices or deforestation to create more accommodations and other tourism infrastructure.

Sustainable tourism management is important since the number of visitors a destination is designed to handle is unique to each one. Short-term rentals may work for certain places, but they could raise rent prices for others and push out local residents to make more room for visitors. In Barcelona, 2017 saw 40% of tourist apartments rented out illegally, making it harder for the locals to find affordable accommodations—only one of the many reasons why the city’s residents organized protests against unregulated tourism over the following years.

It’s the same thing with the environment. Large crowds of tourists in natural destinations may drive wildlife to places outside of their natural habitats, disrupting the delicate ecosystem. In some cases, crowds can negatively influence fragile environments or create more opportunities for human-wildlife conflicts . 

That’s not to say there aren’t plenty of positive aspects to tourism, however. When tourism is sustainably managed, it can be an incredible tool for protecting the environment. Admission dollars to natural areas or animal sanctuaries often go directly towards conservation and environmental education. Tourism can also strengthen local economies and help support small, family-run businesses at the same time. It’s finding that delicate balance between using tourism to fuel the economy while keeping the surrounding environment protected that often presents the greatest challenge.

What Can We Do?

  • Plan your trip during the off season or shoulder season .
  • Dispose of your waste properly (don’t litter) and bring along your reusables .
  • Show respect for local customs and attractions.
  • Explore areas outside of the most popular spots.
  • Prioritize family-owned and local businesses.
  • Educate yourself on sustainable travel practices.

In most places, overtourism is not a hopeless case. Destinations all over the world have already demonstrated ways to overcome the obstacles presented by overcrowding and unsustainable tourism management.

East Africa, for example, has turned gorilla trekking into an exclusive, once-in-a-lifetime experience by issuing limits on daily permits, all while maintaining conservation efforts inside native forests and steady employment for local guides. In Antarctica, the Antarctic Treaty restricts the size of cruise ships that land there as well as the number of people they can bring ashore at one time; it also requires a minimum guide-to-tourist ratio while tourists are off the boat.

Local governments and tourist organizations, of course, are largely responsible for maintaining sustainability in the tourism industry, but certain approaches to mitigate the negative effects of overtourism can come down to the individual traveler as well. One of the best ways to become a responsible tourist is by looking outside of the mainstream travel destinations. Consider outer cities or less-visited attractions, or head towards more rural spots to avoid crowds altogether while experiencing a glimpse of a destination’s daily culture outside of the popular areas. There are countless places that want and need more tourists just waiting to be explored.

However, if you just have to visit that bucket-list destination known for its large crowds, consider visiting during its off season or shoulder season instead of peak travel season. Residents who rely on tourism as a source of income need support during the off season more than any other time of year, plus it will save you money as a traveler since accommodations and flights tend to be cheaper. Even better, off season travel puts less pressure on the environment.

Overtourism in Machu Picchu, Peru

The tourist industry surrounding the famed archaeological city of Machu Picchu in Peru has been largely responsible for the country’s economic growth since the early 1990s. The number of tourists who travel to the 15th-century citadel has quadrupled since the year 2000; in 2017, 1.4 million people visited, an average of 3,900 per day. The site, which sits on a series of steep slopes prone to heavy rains and landslides anyway, is being further eroded by the thousands of visitors who walk the ancient steps each day.

The sharp rise in visitors, combined with a lack of management strategies, prompted UNESCO to recommend that the Peruvian state redraft its overall vision for the site with conservation in mind rather than primarily tourism growth. UNESCO threatened to put Machu Picchu on the “List of World Heritage in Danger” in 2016 if the property didn’t clean up its act.

Beginning in 2019, a new set of tourist restrictions was put into place at Machu Picchu, including limitations on visitors, admission times, and lengths of stay. Tourists are now limited to two daily time slots to relieve pressure on the site and are required to hire a local guide on their first visit.

Overtourism in Maya Bay, Thailand

First made famous by the movie "The Beach," the stunning turquoise waters of Thailand’s Maya Bay have been attracting visitors ever since the film’s release over 20 years ago. Seemingly overnight, the small bay went from a quiet hidden beach on the island of Phi Phi Leh to one of the country’s most popular destinations, bringing hoards of beach-goers along.

According to BBC reports, Maya Bay went from seeing 170 tourists a day in 2008 to 3,500 in 2017, resulting in the death of a majority of its coral reefs. By June 2018, the environmental depredations from litter, boat pollution, and sunscreen had gotten so bad that the government decided to close the beach completely for four months to allow the bay to heal. After the initial four months were through, the government went on to extend the closure indefinitely .

The extreme measure has brought a few positive signs for the environment there. About a year after the initial closure, park officials shared footage of dozens of native black-tipped reef sharks re-entering the bay . A team of biologists and local residents are also working on an ongoing project to plant 3,000 corals in the bay to increase the number of fish and improve the ecosystem.

Overtourism on Mount Everest

While we tend to think of Mount Everest as a remote and unattainable adventure, the destination has actually been suffering from overcrowding for years. Images of hikers standing in line as they try to reach the summit from the Nepalese side aren’t uncommon, and in a high-altitude environment completely dependent on oxygen, long waits can get deadly fast.

Those crowds also accumulate a lot of waste. Between April and May 2019, nearly 23,000 pounds of garbage was collected from Mount Everest, a Guinness Book of World Records in terms of trash. The trash was spread out almost equally between the main basecamp, nearby settlements, high-altitude camps, and the most dangerous portion of the summit route.

One of the most challenging problems lies in the economic value of Mount Everest, which is Nepal’s most lucrative attraction. In the 2017-2018 fiscal year, Nepal received an estimated $643 million from tourism , accounting for 3.5% of its entire GDP.

Overtourism in Venice, Italy

Venice has become the poster child for overtourism in the media, and for good reason. Over the years, the government has been forced to set limits on the number and size of cruise ships that spill visitors into the city, as well as a proposed tourist entrance tax.

The tourism industry hasn’t just resulted in an increased cost of living, but in a decreased quality of life for Venice residents. The local population in Venice has declined by two-thirds over the last 50 years, its cruise ship industry accommodating several hundred ship departures and 1 million passengers each year. According to Bloomberg, there were a total of 5 million visitors in 2017 compared to the resident population of just 60,000 .

In late 2019, when the city experienced a series of floods from record-breaking high tides, some Venetians argued that cruise ships were to blame . The wakes from massive ships were literally eroding the city, while widening the canals to accommodate larger ships throughout the years had damaged coastal habitats for wildlife as well as the physical foundations of the city.

Most of these tourists stick to the city’s most famous landmarks, concentrating large numbers of crowds into small spaces that were not designed to hold them. Its historic buildings and watery ecosystem, already fragile, are certainly feeling the pressure, while the influx of temporary visitors continues to inhibit locals from living their lives. As one of the most active cruise ports in the whole of Southern Europe, Venice is on track to become a city with virtually no full-time residents.

Definitions

Tourism today is paradoxically dominated by two opposite aspects: its sustainable character and overtourism. Since its creation by Skift in 2016 (Ali 2016 ), the term “overtourism” has been a buzzword in media and academic circles, although it may only be a new word for a problem discussed over the past three decades.

Overtourism is a complex and multifaceted phenomenon destructive to tourism resources and harmful to destination communities’ well-being through overcrowding and overuse (Center for Responsible Travel 2018 ; International Ecotourism Society 2019 ) as certain locations at times cannot withstand physical, ecological, social, economic, psychological, and/or political pressures of tourism (Peeters et al. 2018 ). Overtourism is predominantly a problem producing deteriorated quality of life of local communities (Responsible Tourism n.d. ; The International Ecotourism Society 2019 ; UNWTO 2018...

Overtourism: How to combat its effects

Millions more of us are descending on the same handful of tourism hotspots each year, giving rise to the very modern phenomenon of overtourism.

More than 125,000 people visited Venice on Easter Sunday this year, presenting a small city with a big problem. Having long since shrugged off any notion of a tourist season, the Queen of the Adriatic is routinely submerged by tourists, water or both. But there are peaks within peaks, and the Easter influx worried city authorities. So, before the May Day weekend rush, they deployed a radical new weapon in the fight against overcrowding; at two key bridges leading to the city's historic heart, metal turnstiles appeared overnight.

The barriers would be shut if crowds reached dangerous levels, and only residents carrying a Venezia Unica transport pass would be permitted entry. But the radical experiment was controversial, stoking an increasingly fraught debate taking place in Venice and elsewhere.

Each year, millions more of us are travelling, and a new word for the problem this new age of mobility creates — overtourism — reflects a heightened level of anxiety in tourism hotspots.

"I've been trying to get people to think about the impact of tourism for nearly 20 years without getting very far," says Justin Francis, CEO and co-founder of British travel company Responsible Travel. "But now it's on everyone's lips because, after 50 years of staggering growth, the locals are taking to the streets. We're seeing a global tourism backlash, and I think it's a defining moment in the history of the industry."

In Venice, that backlash has focused on the cruise ships that disgorge day-trippers into a city of narrow bridges and canals. It's targeted successive mayors with euro signs in their eyes, and landlords who've driven rents skywards by putting homes on Airbnb. On Easter Sunday, opposition turned on the turnstiles. Despite being put in place to help ease overcrowding (they weren't needed, as it turned out), their mere presence served to exacerbate a feeling among residents that Venice had become a floating theme park. One activist group tried to tear them down; a protestor carried a sign with Mickey Mouse ears bearing the slogan: 'This is not Veniceland'.

"The gates are an experiment but they also work as a publicity stunt for our mayor," says Giovanni Di Giorgio, a member of Generazione 90, a campaign group set up in 2016. Giovanni, who's 24 and has always lived in Venice with his parents, says that the "drastic measures" were only a sop to residents' concerns, and not a meaningful solution to a problem that's about more than crowds on St Mark's Square.

"I've seen the ships since I was born — they used to dock right next to my house — and it seemed too much to me even as a small child," he adds. "You can't morally prosecute people for being tourists but I think the first sign of overtourism isn't the crowds but when a community shrinks and closes in on itself."

Venetians have become an endangered species; their population dwindling from a peak of 164,000 in the early 1930s to little over 50,000 today. The annual tourist population has risen to more than 30 million, meanwhile, or to a daily average of more than 80,000.

Globally, startling statistics lie behind the plight of residents in destinations as small as the Isle of Skye and as big as cities such as Barcelona. Last year, international tourist arrivals grew by 7% to 1.3 billion. The UN forecasts this figure will rise as the world's population grows — and while emerging economies continue to become travelling ones. In China, the number of overseas trips made by residents rocketed from 10.5 million in 2000 to 145 million last year. The UN predicts this will rise to more than 400 million by 2030, a quarter of the current global total.

Moreover, whole generations of the newly mobile, in China and beyond, tend to seek out the same destinations. "I think what governs the industry right now is the TripAdvisor top 10, the listicle and Instagram," Justin Francis says. While for many of us, heaving crowds are a deterrent, that aversion evidently doesn't apply to everyone else. "I last went to Prague in 1988 and decided I wasn't going back because there were already too many visitors," says Harold Goodwin, emeritus professor and director of the Institute of Place Management at Manchester Metropolitan University. "But most of us just get used to places getting more and more crowded."

The results can be direct and physical. Millions of feet per year do the kind of damage to attractions such as Machu Picchu in Peru, and Angkor Wat in Cambodia that it takes the elements centuries to inflict. But after decades of assumptions about the positive economic and employment benefits of tourism, the balance is tipping in many places — and the effects are often more complex.

Skift, a US-based travel media company, published a report on overtourism in 2016. In its foreword, Skift's CEO Rafat Ali said that overtourism 'represents a potential hazard to popular destinations worldwide, as the dynamic forces that power tourism often inflict unavoidable negative consequences if not managed well'. He added: 'In some countries, this can lead to a decline in tourism, as a sustainable framework is never put into place for coping with the economic, environmental, and sociocultural effects of tourism. The impact on local residents cannot be understated either.'

Money matters

Venice's economy has come to depend on tourism, making the situation here harder to manage as visitor numbers have grown. But the long-term effects of that short-term approach are being felt by people like Di Giorgio. As well as the depressing results of the population flight from Venice, life for those who remain has become harder. Historic houses have slowly been converted into hotels. And the rising popularity of holiday letting companies such as Airbnb has created a new class of landlord who buy up properties purely to service the new market, contributing little to the city in taxes. The result is that residents have been priced out of their city. "All my friends leave or live with their parents because there is no other option," Di Giorgio says.

A comparable effect is affecting more remote destinations. For example, in June, a Channel 4 News report discovered there were 550 Airbnb listings on Skye, an island in western Scotland with fewer than 5,000 households. The reason for this is that landlords can make more money from short-term lets than they can from renting to locals. Unfortunately, this has led to a social housing shortage on the island.

The mushrooming of available beds in the sharing economy has been a boon to destinations seeking a lift in tourism numbers — building hotels is a slow, costly and risky business by comparison — but in many other places, authorities are being asked to put the brakes on the Airbnb bandwagon. In some areas with large numbers of Airbnb rentals, residents have also complained of antisocial behaviour, while in Iceland, a law was passed in June 2016 limiting the number of days a person can rent out their property on Airbnb to 90 a year; any more and they require a licence from the state. Similar restrictions now operate in Barcelona and Amsterdam.

Andrew Sheivachman, Skift's business travel editor and the author of its overtourism report, says Airbnb has, to some extent, become an industry whipping boy. He points out that the company does not control the budget airlines or the tourism board marketing budgets that bring travellers into destinations in the first place. Airbnb, meanwhile, says it is increasingly working with destination authorities to promote a more sustainable approach.

Putting up turnstiles and restricting home rentals are just two of the solutions tried so far. Elsewhere, more extreme measures have been adopted. For example, this June, Thai authorities closed down an entire beach for four months to let it recover from overtourism. Maya Bay, on the island of Koh Phi Phi Leh, had become so overrun since Leonardo DiCaprio's 2000 film The Beach made it famous that its ecosystem — particularly its coral reef — was on the brink. When the bay reopens, there will be a cap of 2,000 tourists a day (half the current number) and boats will be banned from dropping anchor there.

But even a temporary ban on visitors would sink an economy like Venice's, so dependent has it become on one of the biggest threats to its future. In Amsterdam, as well as restricting home rentals, political parties in the city announced plans in May to stop cruise ships mooring in the centre. They also revealed a proposal to raise tourist tax (on accommodation) from 4% to 7%. The city has already cracked down on antisocial behaviour — for example, imposing fines for singing in the street and banning that stag trip staple the beer bike.

Other attractions have imposed higher entry fees in an attempt to deter tourists. At a national level, emerging destinations Botswana and Bhutan have gone for a high-value, low-volume approach, targeting fewer, bigger-spending tourists. "But should we feel uncomfortable that travel should just be for the rich again?" Justin Francis asks.

Authorities in Venice have rejected this approach, insisting cities must be free to visit, but it is considering a ticketing scheme for St Mark's Square. Many destinations are also working to tackle the herd mentality of tourists, and the easy temptation among destinations to promote the biggest attractions. "Venice should say, 'I know you want to visit St Mark's Square, but look at all these amazing places you can see,'" Giovanni says. "You can explore the islands, which are really cool and part of the larger identity of the city."

In Iceland, where visitor numbers have exploded in the past decade — exceeding two million last year — tourist authorities have begun a campaign to market areas beyond the crowded capital, Reykjavik.

Tourists tend to act like moths to the flame of the most famous, most Instagrammable destinations and attractions, but they have an individual responsibility to resist this impulse. "The top-10 thing is partly driven by our fear of missing out but we should be less fearful, because ignoring the obvious can often lead to the most magical experiences," says Francis, who also suggests travelling out of season, wherever possible.

But even where tourists and the custodians of destinations are able take steps to ease the problem, it can be hard to see a solution in a rapidly expanding world, and within an industry that can express some of the worst excesses — as well as best opportunities — of the free market. Sheivachman believes only the next global economic downturn will bring meaningful restraint, just as it did in 2008. "Are the places that have taken all this money from tourism going to push hard to market to them and bring them back?" he wonders.

"It would help if short-haul aviation were more expensive but it wouldn't take the problem away," adds Goodwin. "You can try to control accommodation, but I've thought long and hard, and while there are things you can do to manage the problem, and make it marginally better, can you take overtourism away? I think you probably can't."

In Venice, a dwindling population of residents are waiting to find out. "We must hope something will change," Giovanni says.

Five hotspots of overtourism

Venice, Italy The historic Italian city, precariously built in a sinking lagoon, attracts around 30 million visitors a year but is routinely choked with tourists, while residents have been forced out by rising housing costs.

Barcelona, Spain Professionally run home rentals are pushing up rents in the city. In a bid to root out unlicensed properties, an enlarged team of inspectors has been given greater access to data related to Airbnb listings.

Maya Bay, Thailand The beach became a Thai tourist hotspot after it appeared in the 2000 film The Beach, starring Leonardo DiCaprio. This year, Thai authorities shut it down temporarily and announced plans to limit visitor numbers.

Reykjavik, Iceland Tourism has been a big part of Iceland's recovery from its 2008 financial crisis, but soaring visitor numbers have put increasing pressure on Reykjavik's transport infrastructure and healthcare system.

Machu Picchu, Peru The 'lost city' of the Incas is a global overtourism case study. As of last year, visitors have to buy tickets (for either a morning or an afternoon time slot) and can only explore the site with a licensed guide.

Can the tourism industry survive the climate crisis?

From the Solomon Islands to Denali national park, how five communities reliant on tourism are coping as climate change upends their industry

O ne of the terrible ironies of the climate crisis is that some of the most beautiful – and popular – places in the world are also the most vulnerable. Which means as temperatures rise, extreme weather events increase, water sources dry up and natural habitats die, these places are facing another devastating loss: tourists.

Tourism significantly contributes to the climate crisis – about 8% of global emissions – and hordes of visitors cause many more problems, including overdevelopment and degradation of natural areas. However, the revenue generated by tourists can bring enormous economic benefits to these destinations, many of which don’t have other forms of industry or would otherwise rely on extractive industries like mining or logging. Tourism can also bring awareness to environmental problems, such as coral reef bleaching or animal species at risk of extinction, and provide funding for conservation efforts.

This complex relationship was highlighted during Covid-19, when tourism came to a standstill. Carbon emissions plummeted. Wildlife flourished. Leatherback turtles in Thailand laid the largest number of eggs in two decades. But all of this came with a cost. The global tourism industry was hit with an enormous loss, creating an emergency in developing countries. Families struggled to find food. Illegal logging increased in some places, as did poaching .

As tourism starts to rebuild, it is becoming impossible to ignore that the future of the industry is inextricably linked to the climate crisis. The Guardian spoke to people working in tourist destinations around the world to ask how the climate crisis is affecting their industries and their worries for the future.

Denali national park

The single access road leading to Denali national park.

Every year, hundreds of thousands of tourists visit Denali national park, the home to the highest peak in North America. The park, which covers nearly 6m acres in central Alaska, has only one access point: a single winding road that stretches more than 90 miles.

As rising temperatures have thawed the permafrost that lies beneath parts of the road, the road has rapidly deteriorated in recent years. In August, landslide movement forced the National Park Service to close the road at the halfway point and evacuate visitors trapped on the other side.

“The road closed abruptly in late August, on a Tuesday,” said Simon Hamm, the president of Camp Denali, a wilderness lodge on the far side of the closure. “We were given until Friday to evacuate guests, and a few additional days to evacuate staff.”

The closure ultimately cost the business $250,000 in lost revenue, and seasonal staff lost out on wages. A closure like this doesn’t just affect the lodge and the staff, said Hamm, but also the wider community. “We source a majority of our provisions from local fishers and farmers so we were unable to continue to support them.” In addition, the local education system gets funded partially through overnight accommodation taxes.

Recently, the National Park Service announced the closure would continue through 2022, as they work on a long-term solution for the road.

The climate crisis isn’t just causing landslides in Denali national park, but also tundra shrubification , increased wildfires and subsequent smoky conditions, drying of tundra ponds, electrical storm activity and the advance of non-native pests, such as the spruce bark beetle , which can cause disastrous tree die-off. “All of these degrade the natural environment,” Hamm explained.

He predicted the tourism industry across Alaska will see declines in response to tourists’ awareness of climate change: “I can imagine that our clientele will become increasingly self-aware about carbon-intensive travel destinations such as ours.”

Evia, Greece

Marina Valli, the owner of Eleonas hotel on the Greek island of Evia, says that as hotel owners and olive farmers, she and her husband have been seeing climate change in their daily life for years. “The beach is now very narrow as water is coming higher every year. The road that was once next to the beach is now dangerously disappearing. The olive trees do not produce fruits as much as they did a decade before. The flowers bloom earlier or later than we knew.”

This summer, as Greece struggled with severe heatwaves and devastating fires, thousands of tourists were forced to evacuate at the height of the summer season. A video clip of tourists leaving Evia on a ferry in August as flames swept the island went viral.

Left: Flames burn on the mountain near Limni Village on the island of Evia in 2019. Right: Limini Village in 2013.

Valli’s hotel and olive grove on the northern end of Evia was damaged not once, but twice, by wildfire, forcing the couple to cancel weeks of guest bookings in August. Guests continued to cancel in September and October. “People were hesitant to visit us, fearing that the environmental disaster would prevent them from relaxing.” The cancelled bookings combined with the destruction of their olive groves, which they harvest and sell, resulted in a loss of €42,000 ($48,700).

Valli and her husband moved to Evia from Athens 20 years ago to turn an inherited plot of land into an organic olive grove. “We wanted to protect the landscape,” she says. “We live by nature and not at the expense of nature.” To prepare for a future of increasing heat, Valli and her husband are searching for olive varieties that can survive higher temperatures. “We do not know the extent of the changes the climate will bring.”

Solomon Islands

Sunset in the Solomon Islands.

The Solomon Islands is not only one of the most beautiful countries in the world, it’s also one of the most vulnerable to the climate crisis. It consists of nearly 1,000 islands, and the vast majority of the population lives less than a mile from the ocean, where they are seeing drastic rates of sea level rise, more than twice as high as global averages. In recent years, at least five islands have become submerged with another six severely eroded.

Andrickson Trahair grew up on the Solomons, and now owns and operates a small dive shop and guesthouse with her husband, Andrew. She sees the effects of climate change every day: trees being washed away by the tides, the shoreline creeping closer every year – and when Andrew takes tourists out diving, he often comes home with stories of bleached and dead corals. Trahair says that even the winds are unpredictable and different from when she was a child: “The weather system in the Solomons has changed.”

Left: An aerial photo of Sogomou Island in 2014. Right: An aerial photo of Sogomou Island in 1943. More than half the island’s land area has been lost to sea-level rise.

She worries that the climate crisis could have a huge impact on her business. “If there isn’t any coral, there won’t be any fish, then there’ll be less tourists to come to the Solomons as well,” she said. Historically, the main source of industry in the Solomon Islands has been logging ; tourism has made up a fairly small part of the country’s GDP. But Trahair says that over-logging has forced more people to find new ways to make an income, such as tourism. “Now we rely too much on tourism because there are no trees.”

The Trahairs are doing what they can to preserve the natural habitat of their home. In order to combat overfishing, they don’t allow spearfishing around the boundaries of their land. Andrew has started to transplant healthy corals in areas where the coral is bleached or dead. Some of the diving guests have come to help with the replanting. The Trahairs also speak with neighbors and villagers who live near them and encourage them to replant coral. “The coral replanting is doing really well,” Trahair says. “We try our best.”

Victoria Falls

The border of Zambia and Zimbabwe

Water tumbling down Victoria Falls on the border of Zambia and Zimbabwe

Victoria Falls is one of the most striking waterfalls in the world. More than a mile across, and over 350ft (107 meters) high, enormous cascades of water plummet over a ledge of volcanic rock. It’s one of the main tourist attractions in southern Africa, bringing about 1 million visitors a year to the area.

But increasingly severe droughts caused by the climate crisis – and visitor concerns about climate impacts – have seen those numbers dwindle, leaving the local tourism sector worried about the future. Sydney Ncube, who works in the food and beverage department of the A’Zambezi River Lodge, says that drought causes food shortages that affect his industry. “Local farms couldn’t produce enough [fruits and vegetables] due to drought,” he said.

For local tourism businesses, their fear of drought is twofold: the drought itself and the way the drought is reported in the media, further discouraging tourists from visiting and depriving the region of tourism dollars precisely when they need them most.

Left: Victoria Falls in late 2019 after a season of historic droughts. Right: Victoria Falls in the beginning of 2019.

In 2019, a reporter from Sky News filmed a segment at Victoria Falls showing only a trickle of water, talking about the impacts of climate change. John McMillan, the owner of Where To Africa, a tour operation company, said this segment had an enormous impact on the local tourism industry, even months later when the falls were flowing again. “Everyone was saying that the falls had dried up, which resulted in a spate of cancellations severely affecting [tour] operators.”

In countries like Zimbabwe, home to endangered animals such as cheetahs, rhinos and elephants, impacts on the tourism industry can profoundly derail conservation efforts.

“Conservation organizations rely on tourists to raise the necessary money to fund conservation and community development programs, and if tourism dries up, to a large extent so does the funding for this,” McMillan said. “On the other side of the coin, when the food sources of the local population disappear, it results in an increase of poaching incidents as the population struggles to find food and survive.”

Great Barrier Reef

Off the coast of north-east Australia

Fish swimming in the Great Barrier Reef

The Great Barrier Reef is one of the most complex natural ecosystems in the world. It stretches 1,500 miles (2,400km) along the entire north-eastern coast of Australia and is made up of nearly a thousand islands and 3,000 individual reefs, ranging from shallow estuaries to deep sea water. In the past five years, the warming ocean waters have caused three major bleaching events .

Left: A coral in May 2016 after a mass bleaching event. Right: The same coral in March 2016, healthy.

Tony Fontes has spent the last 40 years diving on the Great Barrier Reef and working as a Padi scuba instructor. He says the tourism industry in local areas is inextricably tied to the health of the reef. “A dead reef is not conducive to long term tourism.” Even though he says much of the reef is still in pristine condition, Tony points out that as long as coral bleaching is decreasing the number of healthy reefs, it will eventually end the local industry. “That would be a very sad day indeed. Not only would we have lost the greatest reef in the world, but Australia would lose its most important natural resource. The reef has an economic, social and icon asset value of A$56bn . It supports 64,000 jobs and contributes $6.4bn to the Australian economy.”

In order for the tourism industry to advocate for reef conservation, Fontes says they first need to be willing to admit that the climate crisis a problem. “Many tourism operators don’t want to draw attention to the fact that the reef is less than pristine. It is almost like they believe that if they don’t talk about climate change, it will go away.”

As the plight of the coral reefs becomes more well-known, that attitude is changing. “More tourism operators are running reef restoration programs, getting their guests involved in repairing damaged reefs and raising their awareness of the serious impact of climate change.” Fontes says he’s also seen operators switch to electric-powered boats, and even knows one operator who is building a boat that can run on hydrogen.

Taking care of the reef isn’t just an altruistic act; for many of these dive boat operators, it’s fighting for their livelihoods. “There is no doubt that the health of the reef and the health of the dive industry on the reef are joined at the hip,” Fontes explains. “The reef dies, diving dies.”

  • What Are The Negative Effects Of Tourism On The Environment?

The transportation of tourists results in a high amount of emissions.

Tourism is usually regarded as a boon to a region’s economy. Tourism brings prosperity to the region and provides employment to the locals of the region. However, when tourism becomes unsustainable in nature, it can have disastrous consequences on the environment. When the tourist industry active in the region crosses the legal and ethical barriers to earn more profit, it can lead to massive degradation of the environment in the area. Local human population, flora, and fauna, suffer greatly due to such irresponsible and unsustainable tourism. Some of the ways in which tourism adversely impacts the environment have been mentioned below:

Tourism And Pollution

Transport of tourists results in air pollution.

The movement of tourists from their home to the tourist destination involves transport via road, rail, or air, or a combination of these modes of transport. When a large number of tourists are involved, it invariably leads to a greater use of the transportation system. We all are aware of the fact that emissions from automobiles and airplanes are one of the biggest causes of air pollution. When a large number tourists use these modes of transport to reach a particular attraction, it pollutes the air both locally and globally. Due to the rapid growth in international tourism, tourists now account for nearly 60% of air travel. In many places, buses or other vehicles leave their motors running to ensure that tourists return to comfortable air-conditioned vehicles. Such practices further pollute the air.

Tourism Leads To Noise Pollution

Tourists destinations are often subject to significant noise pollution. Tourists vehicles entering and leaving natural areas create a lot of noise. Such noise is the source of distress for wildlife. Loud music played by tourists in forested areas also disturb the animals living in the area. Often, noise generated by tourist activities for long-term alters the natural activity patterns of animals.

Littering Of Tourist Spots By Irresponsible Tourists

Irresponsible tourists often litter the tourist spots visited by them. Waste disposal is a great problem in the natural environment. According to estimates, cruise ships in the Caribbean produce over 70,000 tons of waste annually. If waste is disposed of irresponsibly in the sea, it can lead to the death of marine animals. Even the Mount Everest is not free of human-generated waste. Trekkers leave behind their oxygen cylinders, garbage, and camping equipment on the mountains and hills. Some trails in the Himalayas and the Andes have been nicknamed the "Toilet paper trail” or the "Coca-Cola trail,” referring to the garbage left behind on such trails.

Sewage Generated At Tourist Spots Contaminate The Natural Environment

Rampant construction of tourist facilities like hotels, cafes, restaurants, etc., in an area without proper arrangement for safe disposal of sewage, can lead to disastrous consequences. Wastewater carrying sewage from such areas often pollutes nearby water bodies. It can lead to the eutrophication of water bodies and the loss of the balance in aquatic ecosystems. Pollution of water bodies with sewage can also lead to health issues and even epidemics that can ultimately wipe out large populations of aquatic flora and fauna and also impact human health adversely.

Tourism Can Spoil The Aesthetics Of The Environment

Tourist facilities built to earn a profit without any concern about integrating the design with the natural features of the place can lead to aesthetic pollution. Large resorts of disparate designs can dominate the landscape and spoil the natural beauty of a place.

Tourism And Natural Resources

When tourism is encouraged in an area with inadequate resources, it will have a negative impact on the ecosystem of the area. In such areas, the local flora and fauna might be deprived of the resources needed to sustain their lives. For example, large volumes of water are consumed to cater to the needs of the tourists, run hotels, swimming pools, maintain golf courses, etc. This can degrade the quality of water and decrease the volume of water that is available for the local population, plants, and animals. It is not only the water resources that are depleted. Unsustainable practices by the tourist industry can also put pressure on other resources like food, energy, etc.

Tourism And Physical Degradation Of The Ecosystem

Every ecosystem works on a delicate natural balance. Every species in the ecosystem has a specific role to play in the system. However, tourism often disturbs this delicate balance and creates a great disaster in the ecosystem. When the tourist industry active in an area is completely profit-minded, it pays little heed to the needs of nature. For example, often hotels and resorts are built illegally very close to the beach or inside the core areas of forests. Large patches of natural vegetation need to be cleared to allow space for the sprawling resorts or hotels. As old tourist spots get degraded due to overuse by tourists, newer ‘upcoming’ destinations with fewer crowds become the next favorite of tourists and the tourism industry. The same situation is repeated once more. Unsustainable practices by the tourism industry can thus lead to deforestation, sand erosion, loss of species, changes in sea currents and coastlines, destruction of habitats, etc. Even activities like nature walks can be harmful to the environment if tourists trample on the local vegetation during their walk. Such trampling can lead to reduced plant vigor, breakage of stems, reduced regeneration, etc. Tourists breaking off corals during snorkeling or scuba diving activities can also contribute to ecosystem degradation. Commercial harvesting of corals for sale to tourists also causes harm to coral reefs. Even the anchorage of cruise ships to coral reefs can degrade large sections of the reef.

The Negative Environmental Impacts of Tourism

tourism harmful effects

The tourism industry is one of the fastest growing industries in the world. On a local, national, and international level, tourism is economically and environmentally significant actor that has great power to affect the future development.

Tourism has the capacity to help support communities and instigate positive environmental change when done with the right approach towards the long-term sustainability in regions and complying with the UN’s 17 Sustainable Development Goals that range from eradicating hunger, gender equality to addressing climate actions based on the specific regional needs.

We can see the rise of the positive trend in the last years. Ecotourism and sustainable tourism have gained popularity in the industry but there are still many areas where improvements need to be done. If the number of tourists in a given area is greater than the capacity of the local environment or supporting infrastructure (which is the case of many popular destinations), negative impacts quickly arise and can become overwhelming for the system.

As we embark on new adventures in foreign countries it’s important to realize what environmental impacts our presence poses to local ecosystems and resources. According to the United Nations Environment Programme (UNEP), the three negative environmental impacts of tourism are: the depletion of natural resources, pollution and physical degradation of ecosystems. We will look at these more in detail now.

How does tourism affect the environment? The negative environmental impacts of tourism

Tourism sector has great influence over wellbeing of local residents. It is an industry that flourishes in large cities as well as remote rural areas rich in natural wonders. For many distant communities, tourism is the only opportunity of generating sufficient income to sustain their lifestyle and traditions. It can bring lot of good to regions, but also lot of bad – fast degradation, extinction, and depletion, if not done with the long-term planning and preservation in mind.

In some situations, it is difficult to realize this negative influence until its too late. We already have a few negative examples and data to look at to see the degrading tendency.

#1 The depletion of natural resources

The depletion of natural resources is a growing concern especially in places where resources are already scarce. Water, in particular, is considered a critical resource which is greatly misused in the tourism sector.

I. Water overuse

In many popular tourist destinations, water is overused by tourists in hotels, for breathtaking swimming pools and luxurious wellness areas. When on vacation, most travelers tend to use much more water for personal use than at home, resulting in larger quantities of wastewater and creating water shortages which affect local residents.

The high tourism season goes usually against the natural water cycle of an area and doesn’t consider years with insufficient rainfall – a problem that is on the rise due to climate shift. The driest months of the year are the months of peaking demand for water in resorts and areas of a special tourist interest. These places get crowded with people who expect to have unlimited accessibility to clean water supply from local sources.   

This creates many problems for residents in not having enough water for basic daily needs, as groundwater is often redirected and overdrawn by large hotels, resulting in drying wells of small communities, and increasing salinity of the remaining water table from dissolved minerals in the soil. Additionally, many small farmers struggle with not having water to grow crops – especially during drier years when it hasn’t rained for months.

A special report on Water Equity in Tourism from 2012 mentions a sad statistic. Globally, almost 900 million people still lack access to clean water and 2 million people (mostly children) die every year due to the health problems arising from this hindered access. These numbers include people from countries with popular destinations, mainly in the Global South or Mediterranean.

Zanzibar, Bali, India, but even Greece and Spain are suffering of these consequences. In Zanzibar, an average household consumes a little over 93 liters of water per day, while an average consumption per room in a guesthouse is 686 liters. That is 7 times more. But the difference is even bigger when it comes to a luxurious 5-star hotel room. The consumption rises to unbelievable 3,000+ liters of water per day [3] .

Tourism and agriculture compete for water also in Spain. Spain is important producer of vegetables and fruits for the rest of Europe. The intensive agriculture and greenhouse cultivation requires water to keep up with the demand. At the same time, the country is one of the world’s leading tourist destinations with great demand for water despite the fact that the country has been drought stricken for a couple years in a row due to climate change [4] . Both of these important economic sectors are standing against each other in an unsustainable way.

II. Other resources

The tourism industry depends upon consumption of renewable and non-renewable resources that are available at a given location. This includes variety of minerals, metals, and biomass resources. The industry burns higher amounts of fossil fuels and therefore produces greenhouse gases; affects health of fertile soils needed to grow enough food, and hurts whole ecosystems like, for example, forests or biodiverse  wetlands , and this way the impacts reach even the local wildlife. When more recreational facilities are built, natural habitats with their riches are destroyed and animals are driven away into scarce natural areas or conflict with other human projects.

Land resources, such as forests, are affected when trees are used for building materials or collected for fuel. Tourist attractions and accommodations are heavily reliant on energy for heating, provision of hot water and electricity. That is where the energy demand actually follows the same pattern as water consumption.

Imagine a town like Venice. The town has 271 thousand permanent residents [5] but welcomes every year increasing number of tourists. In 2003, 2.75 million tourists visited the town, while in 2019 this number has risen to 5.5 million [6] . Each visitor consumes energy and resources of the town, further contributing to environmental problems linked with the use of fossil fuels and other non-renewable energy sources.

#2 Overconsumption & Waste production, incl. food waste

What is the most common image of a nice vacation at some beautiful beach town? Good food, drinks at the beach, little refreshments, and attractive sights with a variety of relaxing activities for everyone. When on vacation, most of us want to forget daily responsibilities. This includes meal planning or carrying with us that refillable water bottle or other long-term use items like quality slippers or reusable shopping bags.

When indulging on that new experience, many rely on single-use plastic items that are fast to dispose. In fact, tourists can produce twice that much waste in a day than long term residents. It has been estimated that the marine litter in the Mediterranean increases by up to 40 percent during the peak season [8] .

UNEP estimates that one guest can generate from between 1 to 12 kg of solid waste per day when visiting a new place [9] . The numbers vary based on many factors – location, the type of accommodation, personal preferences, and a character of the stay. Based on the predictions, we would see an increase of 251 percent in solid waste production due to tourism through 2050, if countries do not adopt sustainable practices of addressing product cycle and waste disposal.

Tourists also tend to be more reckless with food. Such behavior contributes to food wasting which is a large problem on its own .

However, waste directly produced by a tourist is not the only waste coming from popular destinations. Large portion of solid waste originates from the background services for tourists – laundries, restaurants, wellness, entertainment and accommodations.

Solid waste and littering can degrade ecosystems and alter the physical appearance of the landscape.  Marine litter harms marine life, often leading to their death, and degrades sensitive and unique, yet vital, ecosystems.

As more tourism facilities are built, sewage pollution also increases. Sewage runoff in seas and lakes damages terrestrial and aquatic ecosystems, including vulnerable coral reefs which are often the main attraction of a place. Pollution of waterways in any way can stimulate excessive growth of algae, leading to eutrophication, and alter salinity and siltation of water bodies. These are changes to the environment make it difficult for native plants and animals to survive.

#3 Pollution

Pollution in the tourism industry comes in many forms: increased emissions linked to transport and higher need of energy, solid waste as mentioned in the paragraph above, sewage, oil and chemical spills, but even the less talked about noise and  light pollution .

One of the reasons why newly hatched sea turtle babies get confused and head in the opposite direction of water, are the artificial lights we installed along coastlines. Baby turtles have strong instinct to follow the light to guide them to the sea where their life journey begins. In nature, the moon reflection on the water was the brightest point on the beach. Nowadays, however, lamps, bars and other lights shine brighter at night and easily confuse the hatchlings to head in the wrong direction and often lose their life because of that.   

Noise pollution arises from transportation and recreational vehicles such as snowmobiles and jet skis. Noisy tourist destinations and thoroughfares can disturb and distress wildlife, especially in sensitive ecosystems that are often the reason why tourists visit the location in the first place.

Cruise ships are among the top polluters. These “floating cities” make extra noise in deep waters and migration routes of many aquatic mammals who are highly sensitive to noise levels in their serene environment. But that’s not all. Cruises release high amounts of raw sewage and waste of passengers directly into the water. Unfortunately, their practices of dealing with waste are not transparent and are corrupt. At the same time, these giant ships burn fossil fuel and release pollutants in the air, including excessive amounts of carbon dioxide [9] .

Scientists have also found that bacteria originating from sewage contamination of coastal waters affect coral reefs in numerous locations and is clearly linked to increased popularity as tourist destination. One badly affected example is the Mesoamerican Reef. The Reef has already lost 80 percent of corals to pollution released from insufficient infrastructure of trending destinations, such as Cancun, Tulum or Playa del Carmen, that host increasing numbers of tourists. The main problem here is too fast development of luxurious resorts without specific plans for upgrading wastewater treatment facilities and infrastructure. Unfortunately, this is a common issue of many special locations of natural beauty.        

#4 Greenhouse gas emissions and contribution to global warming

Most human activities that encompass modern lifestyle contribute to greenhouse gas emissions. Add to this travel to some exotic destination half-way across the globe and the number grows even bigger, adding up large chunk to our carbon footprint. In total, tourism accounts for more than 5 percent of global emissions of carbon dioxide. This number has been growing steadily and made up around 1,600 million tons of CO2 in 2016 [10] .

According to a report from the World Tourism Organization (UNWTO), the transport is responsible for 75 percent of carbon dioxide emissions in tourism. Air, road, and rail transportation are the main means of travel among tourists. The most polluting form of travel in terms of emissions are the flights – airplanes accounted for 40 percent out of total CO2 emissions in tourism sector in 2005 – especially due to low prices of flights that made this way of travel accessible to masses. The next significant polluter were cars with 32 percent [10] .

Energy consumption to provide services tourists expect is the next large CO2 contributor after the transport. Most accommodations still rely heavily on fossil fuel energy to run air conditioners, water and room heating and other basic or extra services (spas, pools) that consume lot of power. Unfortunately, the burning of fossil fuels has impacts globally and contributes to  climate change .

Energy and transport are both needed even when new resorts are built, or to bring diversity of food to offer to guests, to pick up solid waste, or to clean and maintain recreational areas. Carbon dioxide is not the only gas emitted in the air during these processes, other potent greenhouse gasses such as methane or nitrous oxide are as well. The contribution of tourism to climate change is significant and will grow unless switch to renewable energy is made.

#5 Soil erosion and unsustainable land use

Reckless development and fast expansion of infrastructure, insufficient infrastructure like for example not enough parking spots and cars parked on the edges of roads, too crowded natural sites, disrespect of rules (stepping off the path) can easily kickstart erosive processes and speed up degradation of sites.     

Tourism and recreational activities often change soil properties, especially if the number of tourists is greater than the ecosystem capacity to deal with it. In the most visited places, tourists trample the vegetation around trails, slowly creating larger patches of vegetation free surface. Frequently walked trails become compacted, which leads to the decreased soil permeability and higher surface runoff. The combination of these factors then results in progressively eroding trails and areas around them as people try to avoid slippery or muddy surface of the main trail.

The same scenario happens when off-road biking, horse riding, having fun with ATVs or parking cars on the side of the road.

Construction sites of new resorts or their expansion into surrounding natural areas, coastlines or on the mountain sites is a big contributor to erosion. Many projects begin by removing vegetation, which affects the ability of soils to absorb water, often leaving soils exposed and vulnerable for many years before the project is finished.

 Impervious surfaces of roads, parking lots or around accommodation units do not allow water to infiltrate into the ground. This increases the surface runoff which washes off fragmented pieces of soil even faster. In some locations, spaces between buildings create pathways for wind that magnify its erosive power.

#6 Physical degradation of ecosystems and loss of biodiversity

It is estimated that the average rate of expansion of tourism is 3 percent in developed countries and can be up to 8 percent in developing countries [11] . The industry has many physical impacts on the environment where growth happens, and more short-term visitors come by to admire the place. Many popular tourist sites are located in areas of sensitive ecosystems. Ecosystems such as rain forests, wetlands, mangroves, coral reefs , sea grass beds and alpine regions are often threatened because they are attractive places to developers and tourists who seek the special feeling of a close contact with nature’s wonders.

Construction and infrastructure development can include extensive paving, sand mining, wetland draining, marine development and deforestation. Unsustainable land use practices can lead to sand dune and soil erosion and the deterioration of the landscape.

Not only is the physical environment under threat but living organisms and their natural cycles are also altered. Ecosystem disturbance can lead to destruction in the long term. Poor building regulations and land use planning can also alter the aesthetic appeal of the local environment. This puts a strain on both the natural environment and indigenous structures of the area.

Around the world are many ecotourism activities and sustainable tourism businesses that keep environmental values at the heart of their business practices. Conventional tourism businesses on the other hand don’t always consider natural resources, pollution and environmental degradation.

Before you jet off on your next travel adventure be sure to take some environmental values with you. To reduce your ecological footprint as a tourist be sure to conserve the amount of water you use, dispose of waste appropriately, tread lightly on the land, and become aware of the local ecosystems you choose to visit. Wherever you may go in the world do your best to support green businesses and minimize your impact on the environment.

What does the big blue mean to you? Is it a holiday destination, a source of income, as for the 60 million people working in the marine fishing industry, a vital protein source of 151 million tonnes for human consumption, or a home to millions of species? The ocean has a different meaning for everyone, but for all of us, it is a source of life.

Vitamin sea

It is often forgotten that two thirds of the Earth’s surface is covered by water. The ocean is big, resilient and heals the soul, but what happens when it is facing a crisis and cannot revitalize its own wounds? Scientists are predicting that 90% of the world's coral reefs will die by 2050 and that the ocean’s biodiversity is degrading at an alarming pace, due to human activities.

With a growing global middle class and increasing ease of travel, people have achieved greater mobility in recent years. According to United Nations World Tourism Organization, the number of international tourist trips worldwide reached 1.3 billion in 2017, and is predicted to reach 1.8 billion by 2030 .

The World Travel Tourism Council forecasts that the future of travel and tourism will support 400 million jobs and contribute to 25% of global net job creation globally. The infrastructure required to sustain this growth in economic activity has increased pressure on natural resources, biodiversity, as well as on local communities.

Tourism can cause harm, but it can also stimulate sustainable development. When properly planned and managed, sustainable tourism can contribute to improved livelihoods , inclusion, cultural heritage and natural resource protection, and promote international understanding.

Here are three examples of how tourism is harming our oceans, and the efforts to mitigate that harm:

1. The cost of tourism

Various tourist hotspots struggle to manage the ever-expanding influx of travellers. Urban dwellers in cities like Amsterdam, Venice and Barcelona are raising their concerns and anti-tourist sentiment is growing . Tourism-driven gentrification can put pressure on the wellbeing and livelihood of the local community, pushing up real estate prices, making the destination overcrowded, and enhancing shore erosion by tourist activities in coastal areas.

In 2017, Palau and New Zealand started a bold campaign requesting visitors to be environmental agents by signing an eco-pledge when visiting their countries. This small step is crucial to shift visitors’ behaviour towards respecting the culture, protecting the country’s natural and living resources, and preserving the country for future generations.

Awareness of sustainability is more important than ever, as user-generated content and peer-to-peer digital platforms like Instagram, Facebook, Airbnb and TripAdvisor are becoming key influencers of the experience economy, tourism trends, and the attitudes of globetrotters.

2. Toxic sunscreen in our seas

As the number of beachgoers has been growing, so has the use of sun protection products. Many people are unaware but 14,000 tonnes of toxic sunscreen make their way to the underwater world each year. In fact, as many as 82,000 kinds of chemicals from personal care products end up in the oceans. The use of chemical sunscreen, water pollution, coral diseases, rising sea temperatures and ocean acidification, lead to deformations in juvenile corals, bleaching of reefs and prevent corals from growing, reproducing and surviving.

In 2018, Hawaii , Mexico and Aruba announced a ban on non-biodegradable sunscreen lotions. Seychelles took a step further and committed to a blue bond to support the financing of ocean and marine-based projects for positive economic, environmental and climate benefits. It is key to have a holistic and innovative approach to the blue economy as the industry is expected to grow at twice the rate of the mainstream economy by 2030 .

3. Circular tides

Global awareness of the footprint of (micro)plastic from tourism gained momentum in 2018. Researchers estimate that an additional 8 million metric tonnes of plastic ends up in the ocean every year . About 40% of all plastic is in single-use packaging , as tourists litter beaches with straws, coffee cups, water bottles and cigarette butts .

In October 2018, Thailand announced the closing of Maya Beach indefinitely to clean up the unstoppable amount of plastic and drainage that tarnished its coastline. The threat to our oceans requires cross-country and regional collaboration , but most importantly multi-stakeholder global engagements.

Strategic partnerships empowering the public and private sector to reduce plastic waste, develop a circular economy and build sustainable and more resilient communities are critical. The alliance between the world’s largest packaging producers, like the New Plastics Economy Global Commitment are key to forging innovative collective action, and solutions to reducing pollution to save our oceans.

There are both positives and negatives stemming from the increase of human mobility and tourism, therefore it is crucial to find a balance to encourage tourism for economic growth and stimulating sustainable incentives for the conservation of our oceans.

The ocean might seem endless, but we are all on the same boat and need to find mutual solutions to ride the waves together. This is crucial not only for our oceans and marine life, but for human survival.

Hawaii Is a Paradise, but Whose?

A growing number of Hawaiians say that tourism isn’t working for them. Here’s how they are trying to change it.

tourism harmful effects

By Tariro Mzezewa

Locals in Oahu know that the best way to get from Waikiki’s crowded beaches to the cool North Shore is to drive along the island’s eastern coast. The road is framed by mountains, ocean and greenery so lush and beautiful, it’s hard to focus the eye on one place for too long, for fear of missing the next scenic attraction.

On a recent trip along the route, something else stood out: the upside down Hawaiian flags flying at almost every stop.

The flag, which has the union jack in the bottom left corner, instead of the usual top left, hung in storefronts in Waikiki and was printed on T-shirts in Waimanalo, it was stuck on the bumpers of passing cars in Kailua and flying from the backs of trucks in Kahuku and other towns on the North Shore.

The flag has become a symbol of solidarity among Hawaiians who oppose the construction of a large new telescope on Mauna Kea, on the island of Hawaii . Mauna Kea, at 32,000 feet from seafloor to summit, and with 13,796 feet above sea level, is one of the best places in the northern hemisphere, if not the world, to observe the cosmos, experts say. The telescope’s proponents say that it will bring hundreds of jobs to the island and advance humanity’s study of space.

But it has faced fierce resistance from some native Hawaiians for whom Mauna Kea is sacred ground and a place of roots, and their allies. Opponents of the telescope say they are tired of having their land taken for purposes that benefit others and for the often elusive promise of jobs that fail to deliver in terms of numbers or a living wage.

“The struggle at Mauna Kea right now is one of the biggest issues that has realigned many cultural political relationships in Hawaii,” said Kyle Kajihiro, an activist and lecturer at the University of Hawaii at Manoa. “It’s really quite an amazing emergence of Hawaiian activism of cultural awareness.”

The battle over the telescope has revealed fissures that have long existed in Hawaii, a place that is all but synonymous with tourism — the most-popular destination for honeymoons in the United States and a bucket-list perennial. The fight has inspired actions around the islands, all relating to how land is used and who benefits from it.

The spirit of protest is most visible in Oahu, where in Kahuku demonstrators have spent the last several months fighting the construction of eight wind turbines, each standing at 568 feet — taller than the tallest skyscraper in Honolulu. Protesters say the turbines will have adverse long term health effects on the population. The company building them says there is no evidence to support those claims and promises to bring jobs to the area. More than 160 people have been arrested there.

52 Places to Go in 2020

We picked destinations to inspire you, delight you and motivate you to explore the world.

In southeast Oahu, in September, 28 people were arrested trying to block the building of a park and recreation center in Waimanalo, a largely agricultural town. The developers behind the center say it will bring jobs and create a new community space, but opponents fear it will be a magnet for tourists and will destroy the forest and beach used by locals.

In Honolulu, in May, Hilton employees protested, demanding a better contract and job protections. In July, hotel employees went on strike to protest what they said were low wages and the firing of 45 workers by Diamond Resorts, an operator of multiple properties in the United States and Europe. The company said it would turn one of its hotels into a timeshare resort, which requires fewer workers than a traditional hotel.

“We value our dedicated team members at The Modern Honolulu and we were pleased to reach a contract agreement that includes a significant pay increase,” a spokesman for Diamond said. “We are continuing our planned efforts to convert the property into a world-class vacation ownership resort.”

Most people in Hawaii, especially in the tourism industry work more than one job to barely get by, said Bryant de Venecia, communications organizer for the workers’ union, Unite Here Local 5, which represents resort workers.

“Mauna Kea has lit a fire for Hawaiians who are tired of watching their land, resources and work be used at the expense of their well-being,” he said.

Hawaii is the most expensive state to live in, according to the 2018 Annual Average Cost of Living Index by the Council for Community and Economic Research. Groceries, for example, cost 60 percent more than the national average.

“People are tired of being decorative — Hawaiians as well as people who live in Hawaii,” said Maile Meyer, who owns Nā Mea Hawai’i , a bookstore in Honolulu that sells products from smaller local makers. “Y ou’re seeing a phenomenon of natives gathering again and completely finding our way back to each other as part of the solution.”

Jobs aren’t enough

A common thread between these protests is that they are being led by locals. They say that since Europeans first arrived in the 18th century, Hawaiian land has been taken and misused by non-Hawaiians, and often to the detriment of Hawaiians and their traditions. The endeavors that have sparked these recent protests all promise jobs, just as tourism and defense have in the past.

But perhaps for the first time in recent Hawaiian history, natives and locals are saying the quality of these jobs is not good enough.

“We’re having to move away from quantity to quality,” said Laurien Baird Hokuli’i Helfrich-Nuss, the founder of Conscious Concepts , a company that works with local organizations on sustainable tourism initiatives. “Now that local people are getting more agency, they are learning more, going into a more curious space of saying ‘It’s great that this company is providing jobs, but what kind of jobs are they? Are they good jobs? Are they paying a livable wage?”

Tourism is the biggest driver of Hawaii’s economy, accounting for 21 percent of jobs. Nearly 10 million people visited the state in 2018 and in 2019, guest arrivals were expected to surpass that number, hitting a record high. And although more people are visiting Hawaii, they are spending less there.

Locals say that resorts are often owned and run by non-Hawaiians, with Hawaiian people employed in the lower-paying service jobs, and that development often benefits outsiders at the expense of native and local well-being.

“There historically hasn’t been enough consideration for how tourism and tourists can contribute to making life sustainable and really livable for the locals who serve them here,” Mr. de Venecia said.

More than a “play land”

The feeling of escape — of fleeing to a nearby paradise with stunning beaches and luxurious resorts — has long been Hawaii’s appeal to the traveling public. While the hottest trends in travel now are the search for authenticity and ways to experience local life, many people who visit Hawaii are looking to get away from daily life. They come to sit on the beach and drink a matai without thinking about much else. Their interaction with local culture is often limited to watching a hula show at the hotel luau.

“We realized a lot of folks who would visit us who would normally have more consciousness about history and social justice concerns seem to turn off that part of their brain when they think about Hawaii,” Mr. Kajihiro, the activist and lecturer, said, adding that people treat the islands as a “play land.”

But this decision to turn off their brains is hurting Hawaii and Hawaiians, he said.

While working for the American Friends Service Committee, the Quaker peace and justice organization, Mr. Kajihiro and his colleague Terrilee Kekoʻolani studied the environmental and social effects of colonization, militarization and overdevelopment of Hawaii. They learned that tourism was one of the industries with some of the most damaging effects on Oahu, he said, citing overcrowding, a higher cost of living and higher prices for goods.

The pair began offering alternative tours of the island, which they call DeTours, in 2004 and have seen increased interest in recent years. Their work was included in the recently published Duke University Press book “ Detours: A Decolonial Guide to Hawaii, ” a collection of essays, interviews and family histories about ethical and contextualized tourism in the islands edited by Hokulani K. Aikau and Vernadette Vicuña González.

The tours are given to groups of people who want to learn about Hawaii from the perspective of local Hawaiians. They include a deep history on the ways military life is hidden across the island. During a typical tour, guests go to Iolani Palace, the Hawaiian royal residence, then to Chinatown and some of the old neighborhoods where new immigrants to Hawaii traditionally settled. The next stop is usually Fort Shafter, the headquarters of the United States Army Pacific; then Camp Smith, but the main part of the tour is Ke Awalau o Puʻuloa — Pearl Harbor.

During a DeTours of Pearl Harbor, Mr. Kajihiro pauses in the “Oahu court” between the Pearl Harbor galleries and the museum and asks guests to look at the placards in the hallway. At the placard that says, “The Hawaiian Kingdom was overthrown in 1893,” he explains that this one sentence has been controversial with the United States government because it acknowledges the government-backed overthrow of Queen Lili’uokolani, which unsettles American claims to Hawaii. In the museum’s Attack Gallery, Mr. Kajihiro points to a small image of the Hono’uli’uli internment camp where Japanese people were held during World War II and uses it as a jumping-off point for a conversation about immigration and civil rights.

“People already come here with so many images and ideas about what Hawaii is that it’s really hard for them to see something different, so that’s why we started calling our work ‘DeTours,” Mr. Kajihiro said. “To swerve off the path that most people are going to see or understand and consume and shake it up by raising some more critical perspectives and introducing a lot of historical facts that are not so pleasant.”

A new type of tourism

The DeTours team is part of a movement looking to change what tourism means in Hawaii. Ms. Nuss, of Conscious Concepts, is originally from Oahu and returned in 2009 after working in hospitality in the Caribbean, New York, Miami and other places on the United States mainland.

“ I came home seeing something happening in Hawaii that I didn’t see when I left,” she said. “My generation was stepping into their leadership roles and doing it differently, reconnecting for a movement back to the land.”

But she quickly realized that what many companies were doing didn’t align with her vision for supporting tourism while ensuring the well-being of overworked Hawaiians.

In 2015, Ms. Nuss created her company to find ways to support Hawaiian businesses function sustainably while also remaining a key part of the most important sector in Oahu — tourism. Ms. Nuss has worked with farms, artists and nonprofit organizations to change their offerings so they can appeal to tourists, while still benefiting Hawaiians. A farm hoping to attract tourists to volunteer might turn to her to figure out the best ways to reach them. She described her work with as “consciously creating experiences for travelers and opportunities for locals.”

“I had a realization about how our tourism industry is presently run, which is coming from the commodification of culture,” she said. “I realized what was happening in my communities and the value systems that were driving it were contradictory to the form of tourism that I was being a part of.”

To give tourists a more authentic experience of “the real Hawaii,” the artists Roxy and Matt Ortiz, invite them into their studio in the Kaka’ako district of Honolulu. The couple is known for their elaborate murals of fanciful tree houses, which they create under the name Wooden Wave .

“When people come see us work, it gives them a totally different way to experience Hawaii,” Ms. Ortiz said. “And it’s a fun way for us to give tourists a different experience than they usually see in those brochures.”

In these studio visits, guests can see the couple’s work in progress, but also learn about ahupua’a, the ancient system of land division, in which the island was separated into slices, each slice running from the top of the local mountain to the shore. During the visit, Mr. Ortiz explains that each ahupua’a included forest area up high and a cultivated area below, and depending on the politics and economy of each ahupua’a, its size was different from another.

Mr. Ortiz said that even the slightest opportunity for tourists to think about how water and land have always worked together and why they hold importance to Hawaiians can encourage them to be more thoughtful when interacting with locals and the land and sea while visiting.

“When people have some of the history and context they can appreciate the art more and they can experience the island in a more meaningful way,” he said.

Another way tourists can learn about the land and engage with locals is by visiting a local farm like Kahumana Farm in Waianae on the west side of Oahu.

In November, Chloe Anderson, a therapist and teacher in California, visited the farm and stayed for four of her six days in Oahu. There she shared a room with others, did yoga, learned about the produce grown and cooked on the farm and generally felt like she got a more meaningful experience than she would have at a luxury resort, removed from daily Hawaiian life.

“We had like three or four different activities we would do every day,” she said. “But so many things were based off the farm and at the farm. We still had the experience of being a tourist in Hawaii and going on hikes and beach excursions, but also of experiencing something more.”

Some business owners are committed to staying in the tourism sector, and are trying to be as environmentally friendly as possible.

“I don’t think it’s reasonable to expect that people just won’t work in the main industry there is and I don’t think Hawaiians want to stop tourism altogether, but we are all working to find ways of doing it responsibly and thoughtfully,” said Shane Hiroshi Gibler, who co-owns Royal Hawaiian Catamaran , which is based in Honolulu and offers snorkel tours, sunset cruises and private charters.

On Mr. Gibler’s boat, guests are asked not to bring any plastic and recycling is available aboard. Mr. Gibler educates guests an education about fishing, food and the importance of the ocean and the land to Hawaiians. The Royal Catamaran team regularly gathers people to clean up the shoreline and has been working with the Surfrider Foundation to remove ghost nets — fishing nets that have been lost or left behind by fishing boats — from reefs or the ocean.

The idea, one echoed by Mr. Kajihiro, is to encourage tourists to think about how they can leave their resort, even for one day of their trip, and contribute to the place they are visiting.

“The point is to make folks more responsible when they come here and to interrogate this notion that Hawaii is somehow a place for them,” Mr. Kajihiro said. “If you are thinking about coming here, ask yourself: Who are you in relation to this place? Are you bringing something that will be of value to the host, the people who live here? What will be your impact and your legacy be?”

Hawaii’s Unhealthy Relationship With Tourism

It’s time to shift focus and invest in our own communities, residents and industries.

Kayte Jones

Growing up on the windward side of Oahu, I was used to crowds of tourists. I saw a few tourists increase to busloads of tourists over the years.

tourism harmful effects

In the last few years, my family made the decision to move to Big Island, for many reasons. Although it is not the primary reason, I can’t deny that being “priced out” of Oahu was a contributing factor. We moved to the windward side of the island, since that is my comfort zone, where we have found a new home and community that we love.

I couldn’t help but notice the difference in services and infrastructure. I saw the lack of public transportation. There’s a bus system here on Big Island, made up of retired tour buses and City and County of Honolulu buses, that doesn’t run that often or go to most residential areas.

Manini Beach KealaKekua Bay Kona Hawaii island1

Well, that’s funny. This island is huge. Public transportation would be so beneficial to the residents. Not only would a better bus system create more jobs, it would connect people with more job opportunities in different areas.

I shared my thoughts with a friend who told me, “Well, the county of Hawaii has less tourism, so therefore has less money. What did you expect?”

Abundance Of Opportunity

Recently, I took a trip to the Kona side, which is filled with hotels, strip malls, golf courses, just like Oahu. As I walked through a perfectly manicured strip mall, I felt myself becoming angry and resentful. All of a sudden I felt this boiling resentment. No one invests in locals, the people that actually live here. We only build nice things for tourists.

My “bold and creative” solution for the future of Hawaii is to shift our focus from tourism and invest in our own communities, our own residents and our own industries. Tourism has been profitable for our state. However, the impacts of COVID-19 on tourism highlighted just how completely dependent our state is on tourism — and it’s an unhealthy relationship.

We should continue to attract tourists and profit from it, but we should not be completely dependent on it. It’s time to shift our focus.

Don’t we have more to offer than the exploitation of our land, people and culture? Couldn’t we be a model of sustainability for the future through research of our unique ecosystem and climate? Through developments in agriculture and green energy like solar power, wind power, algae farms and geothermal energy? Couldn’t we be an educational destination through investment and development into our university system?

I recently read an article about opportunity zones in Civil Beat, which stated, “More than two years after Congress created opportunity zones as part of the 2017 Tax Cuts and Jobs Act, business advocates on Hawaii island say there’s frustration among local entrepreneurs about a perceived lack of movement from the state to bring new investment into the island’s economically disadvantaged communities.”

I followed the link and clicked my way to the Factsheets section where there was a handy-dandy break down of “Investment Drivers” for each area there are Opportunity Zones, including Hilo, Kona, Honolulu, Kahului and Molokai. On the factsheet for Hilo, I found multiple “investment drivers” listed: economic, health care, government, education and research, ports and cultural, along with areas, institutions and businesses ripe for investment in each category.

Apparently, there is an abundance of opportunity out there. Imagine my surprise to see all of this opportunity in my own community, listed so neatly on this factsheet.

Hawaii has more to offer than hotels, luaus and Instagram-worthy photos. Our tropical climate and fertile land are ideal for agricultural development, yet we import most of our food. Investing in our agricultural industry would not only shift our focus from tourism and support local farms, but would also help Hawaii to be less dependent on exports for food.

Hawaii’s climate also creates a unique opportunity for our state to be a model of sustainability via research and development into sustainable sources of energy, such as solar power, wind farms, geothermal and algae farms. The University of Hawaii is a land-, sea- and space- grant institution recognized as a research university. Investing in research and education can make Hawaii an educational destination.

Lastly, and most importantly, we can shift our focus from tourism to our people here at home through infrastructure investments. That means that even areas with low tourism rates get nice things too. Why should we expect outside investors to come in and invest in areas of our state that we don’t invest in ourselves?

Not only would strengthening agricultural infrastructure help Hawaii become less dependent on exports, it will keep our money in the state. Every time there is a crisis, or a natural disaster, residents of Hawaii worry about whether or not cargo ships will make it into our harbors. We worry because most of us are accurately aware of our state’s dependence on exports.

I’m not OK with accepting that my new home has less infrastructure because we have less tourists.

While I loved living on Oahu, I love living on Big Island for different reasons. But this move has shown me the differences between an island catered to and funded by tourism and an island sustained by residents. I have no problem going to the post office to get my mail because we don’t have mail service.

I don’t mind that county water isn’t available in many areas. I enjoy living off the water grid and utilizing a catchment system because I want to live sustainably. I don’t mind some unpaved roads. A poor bus system doesn’t bother me, because I have a car.

What I’m not OK with is accepting that my new home has less infrastructure because we have less tourists.

A community’s value is not determined by its average number of tourists. Our state is more than a tourist destination. Our culture is not meant to be marketed and sold. The people of Hawaii are worthy of investments that improve residents’ standard of living, and not just projects that attract more tourists.

We’ve known for decades that we need to diversify our economy to be less reliant on tourism. It’s time to shift our focus to a more sustainable future for Hawaii.

This article makes a great point but the author forgets that many people today are against progress unless it's progress to build new stores. The NIMBYs and CAVE people do their best to stop progress. They are against geothermal energy, carbon neutral energy, space exploration(from telescopes to space ports), and any other form of progress that would give Big Island a step away from relying on tourism. We sit between a rock and a hard place. Whomever figures out this problem and gets everyone on board will be in the running for the Nobel Prize.

How can we reduce the negative impact of tourism?

1. How does tourism impact the environment?

2. what are the social impacts of tourism, 3. how can we reduce waste in tourism, 4. what is overtourism and how can it be managed, 5. how can tourism benefit local communities, 6. what role does education play in sustainable tourism, 7. how can local communities be involved in tourism development, 8. what are some examples of sustainable tourism practices, 9. how can tourists contribute to reducing the negative impact of tourism, 10. how can governments promote sustainable tourism, 11. what are the economic impacts of tourism, 12. how can we measure the sustainability of tourism.

Tourism is a powerful industry that has the capability to positively contribute to economies, cultural exchange, and development. However, it can also have negative effects on the environment, communities, and local cultures if not managed properly. In order to reduce the negative impact of tourism, there are several key strategies that can be implemented.

One of the most effective ways to mitigate the negative impact of tourism is through sustainable tourism practices. This means promoting responsible travel and ensuring that tourism activities are carried out in a way that preserves natural resources, respects local communities, and benefits the destination in a long-term manner. Sustainable tourism practices can include minimizing waste, conserving energy and water, supporting local businesses and communities, and promoting cultural preservation.

Another important strategy is managing visitor numbers and distribution. Overtourism, which occurs when popular destinations are overwhelmed by an excessive number of tourists, can lead to overcrowding, pollution, increased strain on infrastructure, and degradation of natural and cultural resources. Implementing policies to manage visitor numbers, such as implementing quotas, regulating tour operators, and promoting alternative destinations, can help spread the economic benefits of tourism more evenly and relieve pressure on overcrowded areas.

Furthermore, it is crucial to involve and empower local communities in tourism development and decision-making processes. Local communities often have a deep understanding of their own environment, culture, and resources, and their involvement can help ensure that tourism development is sustainable and inclusive. Engaging with local communities through capacity building, training, and consultation can help create a sense of ownership and encourage responsible tourism practices.

Additionally, education and awareness play a vital role in reducing the negative impact of tourism. By educating both tourists and local communities about the importance of sustainable tourism and the potential consequences of unsustainable practices, we can foster a greater sense of responsibility and encourage positive behavior change. This can be done through educational campaigns, information centers, workshops, and locally-led initiatives.

By implementing these strategies and working together, we can reduce the negative impact of tourism and create a more sustainable and responsible travel industry for present and future generations.

Tourism can have various negative impacts on the environment, such as pollution, deforestation, habitat destruction, and overconsumption of resources. Mass tourism can result in increased waste generation, energy consumption, and carbon emissions. It can also harm fragile ecosystems and wildlife habitats through activities like hiking, diving, and wildlife tourism. Implementing sustainable tourism practices can help minimize these impacts and preserve the environment for future generations.

Tourism can have both positive and negative social impacts on local communities. Positive impacts include employment opportunities, cultural exchange, and infrastructure development. However, tourism can also lead to overcrowding, displacement of local residents, changes in traditional lifestyles, and social inequality. Engaging with local communities, promoting cultural preservation, and supporting community-led initiatives can help mitigate these negative social impacts.

Reducing waste in tourism can be achieved through several measures. Firstly, promoting the use of reusable items such as water bottles and shopping bags can minimize the consumption of single-use plastics. Implementing effective waste management systems, such as recycling and composting, in tourism destinations and accommodations is also crucial. Furthermore, educating tourists about the importance of responsible waste disposal and providing facilities for proper waste disposal can contribute to waste reduction efforts.

Overtourism refers to a situation in which a popular destination becomes overwhelmed by an excessive number of tourists, resulting in negative impacts on the environment, infrastructure, and local communities. To manage overtourism, destination management organizations can implement policies such as visitor quotas, regulating accommodation and transportation services, and promoting alternative and lesser-known destinations. Smart planning and sustainable tourism development can help distribute visitor numbers more evenly and reduce the strain on popular destinations.

Tourism has the potential to bring many benefits to local communities, such as employment opportunities, income generation, and cultural exchange. By supporting local businesses, promoting local products and services, and involving local communities in tourism decision-making processes, the economic benefits of tourism can be spread more evenly and contribute to local development. Additionally, community-based tourism initiatives can empower communities and help preserve local cultures and traditions.

Education plays a crucial role in promoting sustainable tourism practices. By educating both tourists and local communities about the importance of responsible travel, the potential impacts of tourism, and ways to minimize negative effects, we can foster a greater sense of responsibility and encourage positive behavior change. Educational campaigns, workshops, and information centers can help raise awareness and create a more sustainable tourism industry.

In order to involve local communities in tourism development, it is important to engage them through capacity building, training, and consultation. Local communities often have valuable knowledge of their environment, culture, and resources, and their involvement can help ensure that tourism development is sustainable and inclusive. Providing opportunities for local entrepreneurship, supporting community-led initiatives, and giving local residents a voice in decision-making processes can create a sense of ownership and empower communities.

Some examples of sustainable tourism practices include minimizing waste through recycling and composting, conserving energy and water, supporting local businesses and products, promoting cultural preservation, and respecting local communities and their customs. Sustainable tourism practices also involve mitigating the negative impacts of tourism on the environment, such as by preserving natural habitats, protecting wildlife, and promoting eco-friendly transportation options.

Tourists can contribute to reducing the negative impact of tourism by practicing responsible travel behaviors. This includes respecting local cultures and traditions, minimizing waste generation, conserving resources, supporting local businesses, and engaging in activities that have a positive impact on the environment and local communities. By making conscious choices and being aware of the potential consequences of their actions, tourists can help create a more sustainable and responsible tourism industry.

Governments play a crucial role in promoting sustainable tourism through the implementation of policies, regulations, and incentives. They can develop and enforce guidelines for sustainable tourism practices, support community-led initiatives, invest in infrastructure development, promote alternative and lesser-known destinations, and collaborate with stakeholders to ensure that tourism development benefits both the economy and the environment. Governments can also provide financial incentives and support for businesses and organizations that demonstrate environmentally and socially responsible practices.

Tourism can bring significant economic benefits to destinations, such as job creation, income generation, and foreign exchange earnings. It can stimulate the growth of local businesses, support the development of infrastructure, and contribute to the overall economic growth of a region or country. However, it is important to ensure that the economic benefits are distributed equitably and that tourism development does not result in the exploitation of local communities or resources.

There are various tools and indicators available to measure the sustainability of tourism. One commonly used framework is the Global Sustainable Tourism Criteria, which provides guidelines for sustainable tourism practices across economic, social, and environmental dimensions. Other indicators include the Tourism Sustainability Scorecard, which assesses the performance of tourism businesses, and the Sustainable Tourism Certification programs, which aim to identify and promote sustainable tourism destinations and accommodations. These tools help monitor and evaluate the sustainability performance of the tourism industry and guide efforts to reduce its negative impact.

Simple summary.

Communities adjacent to protected areas usually face conflict with protected wildlife. Wildlife tourism is regarded as a tool to mitigate such conflict through bringing economic benefits to villagers and then increasing villagers’ tolerance of wildlife. We used qualitative methods to conduct a case study on a macaque tourism attraction in China and find that tourism may escalate rather than mitigate community–wildlife conflict. Provisioning food is a common way to attract wild animals to visit and stay in human activity areas. In the case of macaque tourism, anthropogenic food provision caused rapid population increase and more intra-group aggressive behaviors. More tourist–macaque interactions resulted in macaques becoming habituated to human’s presence. These ecological impacts on macaques led more invasion to the surrounding community and intensified resident–macaque conflict. Meanwhile, low community participation in tourism generated few benefits for residents and did not help alter residents’ hostile attitudes towards the macaques. Local residents gradually retreated from agriculture as the macaques became more intrusive. We propose a holistic model combining social and ecological perspectives to evaluate the role of wildlife tourism in resolving community–wildlife conflict. We suggest that wildlife tourism should minimize human–wildlife intimate interactions and food provision.

Human–wildlife conflict is a barrier to achieving sustainable biodiversity conservation and community development in protected areas. Tourism is often regarded as a tool to mitigate such conflict. However, existing studies have mainly adopted a socio-economic perspective to examine the benefits of tourism for communities, neglecting the ecological effects of tourism. This case study of macaque tourism on a peninsula in China illustrates that tourism can escalate rather than mitigate human–wildlife conflict. Fifty-three stakeholders were interviewed and secondary data were collected to understand the development of rhesus macaque ( Macaca mulatta ) tourism and community–macaque conflict. The results show that food provision and tourist–macaque interactions rapidly increased the macaques’ population, habituation, and aggressive behaviors, which led them to invade the surrounding community more often and exacerbated human–macaque conflict. Meanwhile, low community participation in tourism generated few benefits for residents and did not help alter residents’ hostile attitudes towards the macaques. Local residents gradually retreated from agriculture as the macaques became more intrusive. A holistic approach to evaluating the role of wildlife tourism in resolving community–wildlife conflict is proposed and practical suggestions for alleviating such conflict are given.

1. Introduction

In the past few decades, protected areas have been one of the main tools for maintaining and improving biodiversity conservation [ 1 , 2 , 3 , 4 ]. However, there are tensions between wildlife conservation and the development of communities adjacent to protected areas [ 5 , 6 ]. The establishment of protected areas deprives communities of natural resources and restricts industrial and agricultural development, suggesting that to conserve ecology and wildlife, those communities sacrifice economic opportunities [ 7 , 8 , 9 ]. Moreover, wild animals often cross the borders of protected areas and enter neighboring communities, causing human–wildlife conflict [ 10 , 11 ]. The costs that wildlife impose upon local people include crop-raiding, livestock loss, human attacks, and opportunity and transaction costs [ 8 , 12 ]. Local residents who suffer economic, social, and health losses may then become hostile to wildlife and conservation, and even harm or kill wild animals for revenge [ 12 , 13 ]. Human–wildlife conflict is therefore one of the main problems besetting sustainable wildlife conservation and the sustainable livelihoods of local communities. “Human–wildlife conflict” in this study mainly refers to the community–wildlife conflict, following most other conservation studies, e.g., [ 12 , 14 , 15 ].

Wildlife tourism development has been proposed as a solution to human–wildlife conflict [ 3 , 14 , 15 ]. Recent studies have focused on examining whether and how tourism benefits can alter communities’ hostile attitudes and livelihoods from the economic and social perspectives [ 16 ]. In this article, we argue that those studies neglect the ecological costs of wildlife tourism. Human–wildlife interactions in tourism can bring about various adaptive ecological and behavioral changes that cause wildlife to become a nuisance and make human–wildlife conflict difficult to manage [ 17 , 18 ]. The introduction of profit-driven wildlife tourism in protected areas can trigger complicity in relation to human–wildlife conflict and result in a divergence from original conservation principles. In order to bridge the above research gap, we propose a holistic approach that synthesizes social and ecological perspectives to examine the interactions among tourism businesses, local community, and wildlife.

We use macaque tourism in Hainan Province, China, as a case study to show how wildlife tourism can intensify, rather than mitigate, human–wildlife conflict. The specific research questions include: (1) How do the community residents cope with the community–wildlife conflict? (2) How does the community participate in tourism, and can tourism benefits change the community’s attitude towards wildlife? (3) How does tourism activities affect wildlife? (4) Does wildlife tourism exacerbate or mitigate human–wildlife conflict if assessing the socio-economic benefits and ecological costs combined?

2. Literature Review

2.1. tourism as a way to mitigate human–wildlife conflict.

There are controversial arguments about whether and how tourism development mitigates human–wildlife conflict in protected areas. Many studies endorse the premise that tourism benefits that accrue to local residents can raise villagers’ environmental awareness, increase residents’ tolerance of wildlife [ 15 ], and transform traditional livelihoods [ 19 ]. For instance, Mbaiwa and Stronza found that in Okavango Delta, three communities participating in tourism had stopped traditional activities, such as hunting, gathering, livestock raising, and crop farming [ 20 ]. Tourism revenue-sharing projects in gorilla tourism in Rwanda and Uganda have received the most research attention, with studies finding that national park officials and local representatives believe that revenue-sharing is the most significant advantage of living adjacent to gorilla national parks [ 21 ] and that residents benefit from tourism revenue-sharing through infrastructure projects [ 22 , 23 ]. Cases from Brazil and Peru also support the argument that tourism benefits local residents, and that local participation in management can generate conservation attitudes and actions [ 24 ].

However, other scholars have questioned the effectiveness of tourism in improving community development and biodiversity conservation [ 9 , 16 , 25 ]. Swemmer et al. pointed out that “benefit sharing is messy, is complex, and occurs at various scales with multiple trade-offs” [ 26 ] (p. 17). Stakeholders at different scales have heterogeneous demands for revenue, for various reasons. For instance, communities in Uganda’s Mgahinga Gorilla National Park were found to want benefits to compensate for crop and livestock losses caused by wildlife, park officials hoped to use tourism revenues to offset the costs of management, and the national government tended to allocate tourism revenues according to the conservation needs of the whole state [ 27 ]. In many developing countries, the government and park authorities have the power to determine the allocation of tourism revenues, and communities lack access to participation in the decision-making process [ 25 , 28 , 29 ].

In addition to unequal power relations and a lack of local participation, the uneven distribution of tourism benefits is another problem [ 16 ]. Within communities, poor residents often perceive that the elite obtain the majority of tourism benefits [ 22 , 28 ]. Hemson et al. noted that only residents in tourism industry gain benefits; most local residents are not beneficiaries of tourism [ 30 ]. Tourism revenues may not be distributed evenly among different communities. For example, residents in the buffer zone of Nepal’s Chitwan National Park are constrained in their use of natural resources, but only those villages close to the park’s entry points benefit from tourism incentives [ 31 ]. In China’s Wolong Giant Panda Nature Reserve, the communities close to main roads gain more income from tourism than the remote communities that bear greater costs of conservation [ 32 ]. The spatial unevenness of revenue distribution has also been found in gorilla national parks in central Africa [ 25 , 33 , 34 ].

Moreover, the distribution of tourism economic incentives is often mismatched. Crop-raiding and livestock loss caused by wildlife are the problems of most concern to local residents [ 25 , 34 ]. However, tourism benefits are often allocated to improving social infrastructures, such as clinics, schools, roads, bridges, wells, and water tanks, rather than direct compensation or the prevention of human–wildlife conflict [ 21 , 22 ]. Because of this mismatch, local people remain hostile towards wildlife [ 30 ]. The locals in Kibale National Park in Uganda regard building elephant trenches as being better than building schools and roads [ 35 ]. Many scholars have therefore suggested that tourism revenues should be used to directly offset losses caused by human–wildlife conflict to more effectively improve local attitudes to conservation [ 22 , 25 , 28 , 34 ].

Generally, existing studies mainly evaluate the role of tourism in conservation from the socio-economic dimension, and conclude that although tourism benefits contribute to changing local people’s attitudes towards wildlife and conservation, the effectiveness of tourism is limited due to the unequal, uneven, and mismatched distribution of benefits [ 16 , 36 ]. By contrast, few studies consider the ecological impacts when assessing the impact of tourism on mitigating human–wildlife conflict. Many protected areas use their unique species as tourist attractions to generate economic revenues. However, wildlife-based tourism development is not without cost. Tourism activities can generate negative effects on wild animals [ 37 , 38 ], which should also be considered when evaluating social and economic benefits [ 39 ]. In the next section, we review the effects of wildlife tourism on macaques as an exemplar species.

2.2. The Effects of Wildlife Tourism on Macaques

Humanity has a long history of interacting with macaques ( genus Macaca ). In contemporary society, free-ranging macaques have become popular tourist attractions. There are 23 species of macaque distributed in Asia, North Africa, and Gibraltar, many of which are strongly involved in the tourism industry [ 40 ].

Wild animals usually avoid encountering humans, which makes wildlife-based tourism unpredictable and uncontrollable [ 41 ]. In non-captive macaque tourism, food provisioning is a common way to tempt macaques to stay in a certain area and become habituated to the presence of people [ 42 , 43 , 44 ]. In some wildlife tourism sites, feeding animals is itself an important tourist experience [ 44 ]. Provision of food is an effective strategy to increase the likelihood of tourists interacting with free-ranging macaques [ 44 ].

However, food provisioning and tourist activities have various negative effects on macaques [ 44 , 45 ]. Anthropogenic foods are highly caloric and are more palatable and more accessible than macaques’ natural foods. Wild macaques therefore spend more time at tourist sites and come to rely on the provided food supply, resulting in changes in their activity budgets and dietary diversity [ 43 , 46 ]. Provisioning also affects the population in diverse ways. A stable, intensive, and abundant food supply can dramatically increase the population of macaques [ 39 , 44 , 47 ]; however, close contact raises the possibility of mutual pathogen transmission between humans and macaques, which can further affect the health and population of the animals [ 48 ].

Macaques in tourism areas gradually develop interspecific aggressive behaviors. The presence and proximity of tourists can elevate Barbary macaques’ anxiety levels [ 49 , 50 ]. Many tourists are not satisfied with inactive wildlife. They often tease monkeys to behave more actively by pointing, waving, slapping, mimicking, yelling, throwing food, and even threatening [ 50 , 51 , 52 , 53 ]. Many studies show that tourists initiate the majority of interactions with macaques [ 54 , 55 ]. Tourists’ provocative behaviors induce monkeys’ agonistic responses such as biting, scratching, hitting, and threatening [ 52 , 56 ]. Because of interspecific differences, tourists generally misinterpret the meaning of monkeys’ behaviors, which may enhance the agonism. For example, Maréchal et al. found that in interactions, most tourists cannot identify the exact meanings of macaques’ facial expressions [ 57 ]. The longer the history of visitors’ interactions with macaques, the more aggressive the macaques may become [ 58 ].

Food provision also intensifies intraspecific agonism. Monkeys fight with each other during the feeding time [ 59 ]. There is a positive correlation between food provision and the frequency of in-group aggression [ 54 ]. Furthermore, tourists like to feed baby monkeys, which they perceive as cuter than adults [ 51 ]. This preference violates the strict hierarchy among macaque groups and increases the rate of attacks on baby and juvenile macaques by male adult macaques [ 51 , 59 ].

Despite these negative impacts, some scholars regard human–macaque interactions in tourism as opportunities that have stimulated the evolution of macaques [ 18 ]. Evidence for this point of view is the robbing and bartering behavior developed by long-tailed macaques at Uluwatu Temple, Indonesia [ 60 ]. The macaques have learned to steal inedible objects such as glasses and hats from tourists and barter the objects for food with the staff. This innovation has been socially learned and has spread in the group, suggesting that human–macaque interactions in tourism can cause significant cultural change in a macaque group [ 61 ].

Existing research shows that tourism affects macaques at the population, behavioral, and cultural levels. Macaques can develop adaptive behaviors in anthropogenic tourism environments. Barrett, Stanton and Benson-Amram called for more studies to explore the roles of animals’ adaptive behaviors in worsening or mitigating human–wildlife conflict in protected areas [ 17 ]. This study uses macaque tourism in China to show that the effects of tourism on macaques can exacerbate rather than mitigate human–wildlife conflict.

3. Materials and Methods

3.1. study site.

The study site is Nanwan peninsula in Lingshui county, Hainan, China ( Figure 1 ). This peninsula consists of three main areas: Nanwan Macaque Provincial Nature Reserve, Monkey Tourism Park, and Nanwan Village. The nature reserve was established in 1965 and covers 10.2 square kilometers [ 56 ]. The reserve contains more than 2000 rhesus macaques ( Macaca mulatta ), which are second class protected animals in China. There is a protection station responsible for conservation work. In 1974, a tourism park was built in the experimental zone of the nature reserve. Food was used to attract wild monkeys into the tourism area [ 62 ]. In 2020, more than 500 monkeys visit the tourism park every day, and approximately one million tourists visit every year. Nanwan Village, which has approximately 550 residents, is also located in the experimental zone of the reserve. Agriculture is still the way of life for some villagers. Macaques often cross the border of the nature reserve and enter the village, causing community–macaque conflict.

The macaques are the only target attraction in this area. There are also some potentially attractive houseboats on the sea, where some water people still live. However, those houseboats are usually seen from the cable cars, few tourists approach them.

3.2. Data Collection

The research team visited the site 10 years ago and conducted a study attempting to understand the tourism development model of the conservation area. The current qualitative study is based on twice fieldwork conducted from 16 to 22 February 2019, and from 28 to 30 September 2020. Data were collected using semi-structured interviews and observation. We used the method of purposive sampling to find the people who best know the situations about tourism, community, and nature reserve. We interviewed 2 managers from the nature reserve, 2 managers and 5 staff from the Monkey Tourism Park, 26 tourists, the chairman of Nanwan Village and other 17 Nanwan villagers. We also interviewed a biologist who had studied the macaques in the park since 2013. Interviews with tourists were mainly conducted at the visitor center. The main questions were about the visitors’ general views on macaques, and how they perceived and reacted to aggressive macaques. Interactions between the tourists and macaques were observed and recorded as field notes. Interviews with managers and staff were conducted in their workplaces. We mainly asked about the development of scenic spots, management of the macaques, and community participation in tourism. The interviews with the nature reserve managers covered the establishment and development of the protected area, the protection of macaques, the relationship between the protected area and the tourism park, and responses to community–macaque conflict. Interviews with the villagers concerned their livelihood, their attitudes to macaques, and management of the nature reserve and tourism park. All interviewees gave their permission to be recorded.

Observation was mainly used to understand the spatial arrangements of tourism park, tourist routes, nature reserve, and community land utilization. For example, the route that tourists go to the park from the mainland and return, the distance between the community and the park, the locations of village mango groves. The spatial relations between the tourism park, nature reserve, and village are essential to understand human–macaque conflict (see Supplementary Materials Figures S1–S4 ).

In addition to the above first-hand data, we also searched second-hand data about the Monkey Tourism Park, such as published research articles (e.g., [ 56 , 62 , 63 , 64 , 65 ]), and news reports (e.g., [ 66 , 67 ]) to help comprehensively understand the history of tourism development and macaque protection.

3.3. Data Analysis

From numerous qualitative data analysis methods, we chose “thematic analysis” [ 68 ] to analyze our collected materials. During the data analysis, the audio records were transcribed first. Then, two authors separately read the first-hand and second-hand data repeatedly to get familiar with the data. Second, we generated many initial codes about conservation conditions, community-macaque conflicts, community participations in tourism, and tourism’s ecological impacts. Third, we thought about the relationships between codes and categorized these codes into many sub-themes and themes, including conservation modes, villagers’ strategies to cope with conflict with macaques, low community participation in tourism, and two main ecological impacts of tourism on macaques. Fourth, each of the two authors reviewed and named the themes. After that, we wrote an outline by relating these themes to explain the story of community–macaque conflict and tourism development, then compared the two outlines to obtain a mutually agreed version and construct a thematic map. The third author then compared this outline with the data to check its validity, and proposed a final thematic map (see Supplementary Materials Figure S5 ), on which the results are based. Finally, the three authors proposed a general model to explain the exacerbating effects of tourism on human–wildlife conflict according to the evidence from Nanwan.

4.1. Coercive Fortress Conservation and Spatial Exclusion of the Community

The community–macaque conflict on the Nanwan peninsula has existed for a long time. In the 1930s and 1950s, before the establishment of the nature reserve, the conflict was solved at the cost of a loss of macaques. To safeguard their crops, community residents killed macaques. When the nature reserve was established in 1965, there were only 5 groups of macaques left, comprising about 115 individuals [ 62 ].

The nature reserve system in China prohibits any use of natural resources in the core and buffer zones, and only allows limited research, education, tourism, and leisure activities in the experimental zone [ 69 ]. This management regulation tallies with the model of fortress conservation, according to which “biodiversity protection is best achieved by creating protected areas where ecosystems can function in isolation from human disturbance” and “only tourism, safari hunting, and scientific research are considered as appropriate uses within protected areas” [ 70 ] (p. 704). The fortress conservation in Nanwan is coercive and underpinned by national laws. All conservation work in the reserve is run from a protection station, which routinely sends rangers to patrol and record at various points in the reserve. Considering that the Nanwan villagers and their ancestors have lived in this area for a long time, this conservation model excludes the community residents from using resources that once belonged to them. It also means that Nanwan villagers sacrifice their development opportunities for conservation.

As a result of the coercive fortress conservation, macaques are well protected. The number of macaques has undergone a rapid increase. In 1988, there were 903 macaques in Nanwan nature reserve [ 63 ]. In 1998, the population was estimated to be 1300 [ 63 ]. In 2019, the manager of the nature reserve told us that the current estimate is more than 2000 macaques.

4.2. Community–Macaque Conflict and the Lack of Ecological Compensation

As the population of macaques has grown, community–macaque conflict has worsened. According to Lian and Jiang [ 64 ], the ecological capacity of Nanwan nature reserve can provide resources for 1900 macaques at most. The current macaque population level has exceeded the maximum capacity. In a study conducted in 2010 [ 65 ], an ecologist has pointed out the problem of ecological overshoot on Nanwan peninsula.

Many bold macaques now enter the community area to search for food. The most damaged crops include mangoes, sweet potatoes, and watermelons. In Nanwan village, nearly every household used to have a mango grove, and selling mangoes was one of their main income sources. When the mango harvest was better, a farmer could earn about $2800 USD to $4200 USD per year. However, when the mangoes are ripe, macaques enter into the groves almost every day. As one resident (L02) described: “We are the poorest village in this town area. When mangoes ripen, macaques come down to eat. They not only eat whatever they can, but also grab and throw away the rest.” Some monkeys have even broken into residents’ houses to search for cooked food or steal eggs from chicken pens. The locals show obvious hostility towards the monkeys by describing them as “public nuisances” and “thieves”.

Because of the legally protected status of the macaques, the community cannot hurt monkeys as their ancestors did in the past. After the establishment of the nature reserve, it was made very clear to the Nanwan villagers that capturing monkeys is illegal. Nowadays, the residents do not have effective ways to expel the annoying macaques. “Many macaques come to the village at a time. You cannot catch them. You cannot beat them. We know it is illegal. If we frighten them, they run to the top of the trees and cannot be driven away. They are animals, we cannot control them.” (L01). Some villagers tried to isolate mango groves from the macaques using nets, but staff from the protection station stopped that defense because they feared that the net may pose a threat to the macaques. The conflict between the community and the macaques became more tense.

As a result, villagers were eager to be compensated by the government for their loss of livelihood. However, the protection station manager said: “There is no special fund for ecological compensation in Hainan Province for macaque damage.” (SM01). Nanwan villagers complained about the lack of ecological compensation: “We live on mangoes, macaques often come down to eat, they [the protection station] do not give us money, even a penny.” (L02). With no ecological compensation, the conflict between villagers and macaques remains unsolved, even though the station manager is aware of the macaques’ crop-raiding.

4.3. Monkey Tourism and Limited Community Participation

The development of monkey tourism brought a new potential opportunity to solve the conflict between villagers and macaques. There is a long history of developing macaque tourism on Nanwan peninsula. In 1974, the staff of the protection station began to feed two groups of macaques and the area received tourists in 1980 [ 62 ]. Around 1985, the Lingshui county government established a tourism company and cooperated with the reserve to develop monkey tourism on a large scale [ 62 , 66 ]. After experiencing 10 years of rapid development, the tourism park began to decline [ 67 ]. To restore tourism development, in 1999 the county government sold the rights of developing the park to a private cable car company. To reinvigorate tourism development, the company built a two-kilometer cableway to connect the mainland to the peninsula, rebuilt the park’s infrastructure, and improved the park’s management [ 67 ]. The tourism development has followed the conservation plan, such that nobody can enter the core zone of the reserve; the tourism park is restricted to the experimental zone and tourists can only interact with macaques when the monkeys freely enter this zone [ 65 ]. The attraction is now a national 4A level scenic area and attracts approximately one million tourists every year.

However, the prosperity associated with the monkey tourism has not resulted in the economic development of Nanwan village for many reasons. The most important is that the enclaved mass tourism model leaves no room for business opportunities for the Nanwan villagers. Most visitors are package tourists. They enter the scenic area via the sightseeing cableway from Xincun town on the mainland. The trip is about two-hour visit. They then either take a cable car or a boat and shuttle bus back. There are no tourism products in the village. Thus, there are few intersections between the tourists’ activities and village spaces. The villagers once applied to do business in the scenic area, but were denied by the manager. “When the scenic area belonged to the county government, we could sell things inside. When the tourism company contracted with the local government, they promised we could still do business inside. But after selling for one month, we were driven away by the tourism company and were not allowed to sell things from then on.” (L08).

Second, the tourism park only employs a limited number of villagers, due to its adoption of a modern business management model. Well paid and skilled jobs can only be from outside the peninsula. There are more than 130 households in Nanwan village. Only about 10 of them have obtained low-salary jobs in tourism to do cleaning and security work. The average salary is about $230 USD per month, lower than working in other places. “Now only some old villagers work in the scenic spot as security guards. They look after the scenic spot during the night.” (L09). Work in tourism is not economically attractive compared with off-farm jobs in the city.

Third, about 10 households rent their land to the company managing the scenic area. However, the contract was signed 20 years ago for a period of 50 years with a land value based on its 1999 evaluation. The village chairman revealed that: “About 10 households have contracts with the scenic area. Rents are low. Now the park pays the rent every year, about $50 USD per household. Only about 10 households receive the money.” (L01). The residents are powerless compared to the company, who is a big tax-payer for Lingshui County. Thus, it is impossible for the residents to push the company to sign a new contract based on the current land value.

The perception of the tourism park manager is that the company is not responsible for community development and compensation for macaque damage. “I am not clear about the negotiation between the nature reserve and the community. It [the compensation] has nothing to do with our park. We are only responsible for business operations. Macaques belong to the nature reserve, who should be responsible for the compensation.” (PM01).

It may be true that for historical reasons, the partnership among the conservation committee, the park company, the village committee, and the villagers was not perfectly designed because the potential dynamics of tourism and the macaques were not clear initially. The major challenge now is that the initial collaboration model was not designed to enable all parties to negotiate and benefit from the collaboration when changes occur. In the next section, we show how the development of macaque tourism is likely to escalate community–macaque conflict, and demonstrate the obligation of the tourism industry to provide compensation.

4.4. Adaptive Macaques and Escalation of Human–Wildlife Conflict

4.4.1. population, aggression, and tourist–macaque conflict.

As with macaque tourism in other regions, developing tourism on Nanwan peninsula has had many ecological effects on monkeys. One of the most obvious impacts is the rapid growth of the macaque population. Food provision is the main method of attracting wild macaques to the tourism park area and keeping them there. Such provisioning started in 1974 and continues now. Usually, the macaques come down from nearby hills every morning, stay in the park area during the day and go back to the hills in the evening. The park staff feed the macaques at 08:00, 12:00, and 17:30 each day with wheat and various vegetables [ 56 ]. In 2013, around 80 g of food was formally provided per individual per day [ 71 ]. In addition, the park sells food for tourists to feed the macaques. Anthropogenic provision can increase macaque populations. A biologist who is studying macaques in the park said that “provision can lead to the growth of the monkey population within the park. My records are from 2013 to this year 2019 and show that the number of fertile adult female macaques has grown every year in this park.” (R1). More fertile adult female macaques mean that there are more baby macaques every year. Zhang et al. recorded 7 groups with approximately 350 individuals visiting the park in 2014 [ 56 ]. According to the official data, the macaque population grew from 393 in 2018 to 433 in 2019. The head of Department of Macaque Management estimated that the number is more than 500 in 2020 and there are about 80 new-born baby macaques every year. The population growth effect of tourism provision corresponds with studies of Barbary macaques in Gibraltar [ 47 ] and Japanese macaques in Oita [ 39 ].

Second, the macaques become habituated to the presence of people and more aggressive to tourists. The provisioned food (80 g/individual/day) is not enough to satisfy the needs of every monkey. Many monkeys develop robbing, biting, scratching, and threatening behaviors towards tourists. Zhang et al. recorded 195 instances of aggressive behavior, most of which were aimed at obtaining food [ 56 ]. Tourist-induced aggressive behaviors accounted for 54.67% of the total [ 56 ]. Visitors often pursue close interactions with monkeys by feeding and touching them, even though the park regulations and tour guides prohibit such behaviors.

During our field observations, we found that when entering the park, tour guides usually counselled visitors not to feed monkeys or hold drinks, foods or colorful bags in their hands, and they repeatedly reminded visitors not to open bags in front of the macaques to prevent robberies by the monkeys. Park managers also set up many noticeboards to remind the tourists not to engage in these “transgressive” behaviors, but still allowed tourists to buy park-provided food to feed the macaques. Tourists usually perceived the monkeys, especially baby monkeys, as “funny, cute, and human-like”, and thus “approachable and playful” (T01). Many tourists ignored or forgot the guides and warnings, and approached the macaques to feed, tease and interact with them. These behaviors are highly likely to incur an attack. Staff in the park’s clinic said that nearly every day there are incidents in which tourists are hurt by macaques. Moreover, there were 45.33% aggressive behaviors initiated by the macaques [ 56 ]. Sometimes monkeys actively rob food, drinks, and inedible objects such as paper napkins and glasses from careless tourists. Some bold adult male macaques may even open tourists’ bags to search for food.

The above evidence shows that macaques in Nanwan Monkey Park have developed adaptive aggressive behaviors through long-term human–macaque interactions to better obtain anthropogenic resources and maximize their benefits. Tourists who are bitten or scratched by macaques need to be given vaccines, which increases the economic cost of the park’s operation and leads to economic disputes with tourists and the tourism company. Therefore, the park has built many wooden “cages” for tourists to eat inside to avoid monkey robberies. A number of security guards have been recruited to constantly remind visitors to pay attention to safety, and stop tourists from engaging in transgressive behaviors. The security guards are also responsible for driving macaques back to the trees when they gather at the visitor center or trails. However, it is difficult for the guards to watch over such a high number of tourists and troublesome macaques. The interviewed biologist revealed that in recent years the park had decided to increase the amount of food provision with the aim of making the macaques fuller and thus reducing their attacks on tourists. Now, in 2020 the head of Department of Macaque Management told that the park fed 50 kg of rice and 10 kg of peanuts for the macaques every day, that is 100 g for an individual per day.

Many measures have been formulated to mitigate tourist–macaque conflict in the park. However, the impact of the aggressive monkeys on the local community on Nanwan peninsula has been largely neglected. The monkeys not only make trouble in the park, but also invade Nanwan village, intensifying community–macaque conflict.

4.4.2. Intensification of Community–Macaque Conflict

It is difficult for the rapidly increasing and aggressive macaques in the tourism park not to influence the community, because the park is next to the community’s mango groves and the macaques are free to range in the park, the nature reserve, and the village. The park is separated from one main piece of village’s mango groves by a wall, which “can only prevent humans entering the park, not stop the monkeys entering the mango grove”, commented by a villager (L16) (see Supplementary Materials Figure S3 ). The interviewed biologist revealed that “Nanwan village is just next to the monkey park. Sometimes park macaques do range in Nanwan Village.” (R01). Although there has been no quantitative research calculating the proportions of park macaques and nature reserve macaques invading Nanwan village, it can be sure that monkey tourism has affected the community–macaque relationship.

The effects of tourism on the population and behaviors of the macaques have contributed to the escalation of community–macaque conflict. First, the fact that the tourism park has provided a stable and increasing food source for macaques has made the park a “reservoir” of constantly reproducing macaques. These macaques inevitably overflow into the surrounding areas including the village, especially when the park does not provide abundant food. A resident (L07) commented that “A few years ago there were more monkeys because they [the park] did not provide enough food for the monkeys, who then came to the village to steal food. Now, they feed more food and monkeys have become fewer in our village.” The village head told that “There were more monkeys disturbing the village in the COVID-19 pandemic compared to past years, maybe because the tourism food provision became less” (L01). The problem is that more provision can only keep macaques in the park temporarily, at the cost of macaques reproducing in the future. Thus, it is predictable that more provision cannot resolve the conflict between the community and the macaques, but will eventually intensify it. Second, the park macaques have become habituated to the presence of humans. When they invade Nanwan village, they are not afraid of villagers. Hence, villagers have few methods to repel the macaques. “After our protection, the macaques live harmoniously with humans. When people treat macaques well and stop hurting them, their courage will increase and they will definitely come to the village to find food to eat.” (SM01). The ecological impacts of tourism on macaques complicate the community–macaque conflict.

Residents’ reactions to macaque invasion provides further evidence of the escalated conflict. Nanwan villagers usually adopt two strategies in response to the ongoing macaque invasions. Some villagers spend more time and energy watching out for macaques to defend their mangoes (see Supplementary Materials Figure S2 ). In the ripe season, they have to stop most other daily work to drive away the invading monkeys, who may appear in the village at any time. Although driving away the monkeys is quite time and labour consuming, this intense defense does not significantly reduce invasion by the macaques. For instance, “Near the harbour, a boss rents the land and has planted many mangoes. The operation is different. They employ special men to drive away macaques all the day. But they said there are still a lot of monkeys going to eat mangoes.” (L06). Even the professionalization of repelling monkeys cannot stop macaque damage. Thus, many other residents have given up planting in most of the mango groves near the hills and the park (see Supplementary Materials Figure S4 ). Some have even abandoned mango cultivation as a main livelihood and have chosen to find jobs in the county town. “Now my family members don’t care about whether the mangoes grow well or not. We find jobs in other places. My parents stay at home, but have also stopped planting mangoes.” (L04). Only about 15 households still plant mangoes now, according to the estimate of the village head. The strategies of intense defense against macaques and retreating from planting mangoes are the community’s helpless reactions to the escalation of community–macaque conflict.

5. Discussion

The Nanwan case shows a dynamic and growing pattern of human–macaque conflict over time. This conflict existed when the community lived on the island before the reserve was established and did not stop when the nature conservation system was implemented. However, conflicts intensified when tourism was introduced. The structures leading to these conflicts are presented in Figure 2 . We argue that making food available to macaques is the critical aspect underlying all of these complicated conflictual relationships.

Integrated model of tourism–macaque–community interactions.

In the absence of anthropogenic and external influences, wild macaques live mainly by foraging for natural food. Under this condition, the macaque population will not exceed the maximum ecological capacity, and in the long term, wild macaques and the natural environment will reach an ecological balance. As the top left loop in Figure 2 illustrates, natural food resources impose a constraint on the growth of macaque populations, and vice versa. In the loop without anthropogenic influence, ecological rule plays the vital role in controlling macaque population.

However, in reality there are usually human communities adjacent to protected areas, and their agricultural crops provide additional food sources for wildlife. Hence, when protected areas lack sufficient food, wild macaques will invade the surrounding communities for extra food. When crop raiding, macaques must bypass communities’ guards, which usually evolves into human–macaque conflict. In the case of Nanwan, the villagers have developed different strategies to cope with human–macaque conflict in different social, historical, and institutional contexts.

Before the establishment of the nature reserve and the legislation of macaque protection, humans had advantages over the monkeys. They often hunted the transgressive macaques to protect their crops, which reduced the wild macaque population. After the nature reserve was established, the advantages were reversed. The villagers were prohibited from hurting the macaques, even for the purpose of protecting their property. Subsequently, the residents adopted a defensive strategy in the short term and attempted to drive the nuisance macaques away. This defense was effective in reducing crop loss and restraining the rapid increase of macaques. However, because of the gradual habituation of the macaques to the presence of humans, the residents have become unable to find effective methods to expel the monkeys once and for all. Thus, their defense strategy has failed to stop the macaque invasion. Human–macaque conflict has heightened; crop damage has increased, and the macaque population has grown steadily. In the long term, as the labour and time costs of defense have continued to increase, the community has begun to retreat, stop planting crops and find alternative livelihoods, resulting in a further increase of the macaque population in the community’s agricultural area. The conservation policies and community’s livelihood strategies determine the community–macaque interactions. In the context of coercive fortress protection, macaques have big advantages over humans, and the community–macaque conflict loop will not be completely mitigated until the community fully retreats from agriculture.

The introduction of wildlife tourism was supposed to mitigate community–macaque conflict. However, food provision has exacerbated the conflict. The Monkey Tourism Park uses food to tempt wild macaques to visit the park regularly, as many other tourism attractions have done [ 39 , 51 , 52 ]. This attracts tourists who want to watch and interact with the monkeys at close range. Close tourist–macaque interactions induce frequent macaque attacks on tourists [ 52 , 56 ], which have resulted in additional economic costs and disputes for the tourism park. To reduce these attacks and their associated costs, the tourism park has increased the amount of food provided to make the macaques more satiated and thereby stop them robbing food from tourists. Thus, a vicious loop has developed. Commercial logic dominates this loop. For maximizing the profit, the tourism park must maintain and increase food provision to attract macaques coming and reduce macaque attacks. As a consequence, the population of macaques will keep growing [ 39 , 47 ]. Macaques may also develop adaptive behaviors, including aggressive behavior, in continuous interactions with humans [ 18 , 61 ].

As the macaque population grows, the food provided by the tourism park can never be enough. Some macaques inevitably intrude into the nearby village to search for edible crops. This widens the macaque–community conflict loop. Because of the constantly reinforced loop in the tourism park, crop damage is intensified as more and more macaques become habituated to and aggressive towards humans. As a result, the macaque population gradually increases and the community retreats from agriculture with a hostile attitude.

This integrated model provides a general theoretical explanation of the dynamic and growing pattern of human–macaque conflict under the impact of wildlife tourism. The model covers the interactions between tourism, the community, and the macaques that we can see. However, it needs more testing and validation before it can be extended to explain conflict between humans and other species in other regions.

6. Conclusions

In protected areas, human–wildlife conflict is one of the main barriers to achieving sustainable biodiversity conservation and community development [ 6 , 12 ]. Tourism is usually regarded as a way to mitigate human–wildlife conflict by involving communities in tourism to obtain benefits that will change their hostile attitude towards wildlife or transform traditional livelihoods [ 3 , 15 , 20 ]. Existing studies mainly focus on examining the effectiveness of tourism in mitigating human–wildlife conflict from social, economic, and political perspectives [ 16 , 36 ], ignoring the biological consequences to wildlife. This study contributes to understanding the effect of using tourism as a tool to mitigate human–wildlife conflict. The provision of food in wildlife tourism can dramatically change the natural ecosystem and the behaviors of macaques, as well as the balance between natural capacity and the number of macaques. Human–wildlife conflict worsens in this scenario.

This research suggests the need for a holistic, integrated, and dynamic approach to evaluating tourism development and solving human–wildlife conflict in protected areas. Human–wildlife conflict is not only embedded in social systems, but also involves ecosystems. Thus, it is not adequate to solely consider the social and economic benefits brought by tourism. It is also necessary to consider tourism’s impacts on wildlife and ecology. As wildlife habitats shrink, more wild animals will cross the borders of protected areas into peripheral spaces, which then become the hot spots at the human–wildlife interface. It should be recognized that it is nearly impossible to protect a species without any human disturbance in the Anthropocene [ 72 ]. Hence, a balanced approach is to assess the mitigating effects of wildlife tourism in human–wildlife conflict by integrating social and ecological/biological perspectives.

Moreover, scholars should pay more attention to the agency of animals. Animals are not passive things waiting for human actions. Wildlife can actively develop adaptive behaviors in anthropogenic environments to maximize its own benefits [ 18 ]. More human–wildlife interactions provide more opportunities for wildlife to acquire more adaptations [ 17 ], such as the robbing and bartering behaviors of long-tailed macaques in Bali [ 61 ]. This adaptation and evolution, when combined with coercive institutional protection, give wildlife many advantages in conflicts with humans and make the conflict unmanageable and uncontrollable, as in the case of Nanwan. Wildlife tourism is based on human–wildlife interactions, and their impact on the adaptation and evolution of wildlife should be fully considered.

Implications

The integrated model of tourism–macaque–community interactions proposed in this study needs validation for other species and in other regions. Trans-species interactions in tourism can generate different effects on different wildlife due to the heterogeneity of species [ 37 ]. Thus, wildlife may evolve heterogeneous behaviors and then influence community–wildlife conflict in different ways. For instance, human–elephant conflict is also a challenging problem due to the excellent memory ability of elephants and their high food demand. Moreover, the diversity of social, cultural, economic, and political contexts in which human–wildlife conflict is embedded means that different regions must adopt different strategies to cope with the conflict. Under China’s current policies, culling protected wildlife is not possible to control wildlife populations, but in some other countries the culling of overpopulated wildlife is a normal ecological management policy. Different social, cultural, and institutional contexts produce different ways to address human–wildlife conflict.

This study has many implications for practice. Our observations suggest that wildlife tourism attractions should design their activities cautiously and minimize human–wildlife interactions and food provision if possible. It is better to control tourists’ behaviors to meet the behavioral patterns of wildlife rather than the other way around. If the tourism sites plan to feed wildlife, it is better to provide food via formal supervised arrangement and eradicate tourists’ accidental and non-regulatory feeding activity [ 44 ]. Furthermore, the institutional design for cooperation among communities, tourism companies, and conservation committees should also be flexible to allow for the adjustment and re-negotiation of benefits and obligations, because the interaction among tourists, wildlife, community, and ecosystem is always evolving. Because, in general, local communities are in relatively weak bargaining positions, it is better for governments to establish special ecological compensation projects for wildlife damage, and control wildlife populations properly according to the principle of maintaining ecological balance.

The Effects of Climate Change

The effects of human-caused global warming are happening now, are irreversible for people alive today, and will worsen as long as humans add greenhouse gases to the atmosphere.

tourism harmful effects

  • We already see effects scientists predicted, such as the loss of sea ice, melting glaciers and ice sheets, sea level rise, and more intense heat waves.
  • Scientists predict global temperature increases from human-made greenhouse gases will continue. Severe weather damage will also increase and intensify.

Earth Will Continue to Warm and the Effects Will Be Profound

Effects_page_triptych

Global climate change is not a future problem. Changes to Earth’s climate driven by increased human emissions of heat-trapping greenhouse gases are already having widespread effects on the environment: glaciers and ice sheets are shrinking, river and lake ice is breaking up earlier, plant and animal geographic ranges are shifting, and plants and trees are blooming sooner.

Effects that scientists had long predicted would result from global climate change are now occurring, such as sea ice loss, accelerated sea level rise, and longer, more intense heat waves.

"The magnitude and rate of climate change and associated risks depend strongly on near-term mitigation and adaptation actions, and projected adverse impacts and related losses and damages escalate with every increment of global warming." - Intergovernmental Panel on Climate Change

Some changes (such as droughts, wildfires, and extreme rainfall) are happening faster than scientists previously assessed. In fact, according to the Intergovernmental Panel on Climate Change (IPCC) — the United Nations body established to assess the science related to climate change — modern humans have never before seen the observed changes in our global climate, and some of these changes are irreversible over the next hundreds to thousands of years.

Scientists have high confidence that global temperatures will continue to rise for many decades, mainly due to greenhouse gases produced by human activities.

The IPCC’s Sixth Assessment report, published in 2021, found that human emissions of heat-trapping gases have already warmed the climate by nearly 2 degrees Fahrenheit (1.1 degrees Celsius) since 1850-1900. 1 The global average temperature is expected to reach or exceed 1.5 degrees C (about 3 degrees F) within the next few decades. These changes will affect all regions of Earth.

The severity of effects caused by climate change will depend on the path of future human activities. More greenhouse gas emissions will lead to more climate extremes and widespread damaging effects across our planet. However, those future effects depend on the total amount of carbon dioxide we emit. So, if we can reduce emissions, we may avoid some of the worst effects.

"The scientific evidence is unequivocal: climate change is a threat to human wellbeing and the health of the planet. Any further delay in concerted global action will miss the brief, rapidly closing window to secure a liveable future." 2 - Intergovernmental Panel on Climate Change

Future effects of global climate change in the united states:.

Here are some of the expected effects of global climate change on the United States, according to the Third and Fourth National Climate Assessment Reports.

U.S. Sea Level Likely to Rise 1 to 6.6 Feet by 2100

Global sea level has risen about 8 inches (0.2 meters) since reliable record-keeping began in 1880. By 2100, scientists project that it will rise at least another foot (0.3 meters), but possibly as high as 6.6 feet (2 meters) in a high-emissions scenario. Sea level is rising because of added water from melting land ice and the expansion of seawater as it warms.

Climate Changes Will Continue Through This Century and Beyond

Global climate is projected to continue warming over this century and beyond.

Hurricanes Will Become Stronger and More Intense

Scientists project that hurricane-associated storm intensity and rainfall rates will increase as the climate continues to warm.

More Droughts and Heat Waves

Droughts in the Southwest and heat waves (periods of abnormally hot weather lasting days to weeks) are projected to become more intense, and cold waves less intense and less frequent.

Longer Wildfire Season

Warming temperatures have extended and intensified wildfire season in the West, where long-term drought in the region has heightened the risk of fires. Scientists estimate that human-caused climate change has already doubled the area of forest burned in recent decades. By around 2050, the amount of land consumed by wildfires in Western states is projected to further increase by two to six times. Even in traditionally rainy regions like the Southeast, wildfires are projected to increase by about 30%.

Changes in Precipitation Patterns

Climate change is having an uneven effect on precipitation (rain and snow) in the United States, with some locations experiencing increased precipitation and flooding, while others suffer from drought. On average, more winter and spring precipitation is projected for the northern United States, and less for the Southwest, over this century.

Frost-Free Season (and Growing Season) will Lengthen

The length of the frost-free season, and the corresponding growing season, has been increasing since the 1980s, with the largest increases occurring in the western United States. Across the United States, the growing season is projected to continue to lengthen, which will affect ecosystems and agriculture.

Global Temperatures Will Continue to Rise

Summer of 2023 was Earth's hottest summer on record, 0.41 degrees Fahrenheit (F) (0.23 degrees Celsius (C)) warmer than any other summer in NASA’s record and 2.1 degrees F (1.2 C) warmer than the average summer between 1951 and 1980.

Arctic Is Very Likely to Become Ice-Free

Sea ice cover in the Arctic Ocean is expected to continue decreasing, and the Arctic Ocean will very likely become essentially ice-free in late summer if current projections hold. This change is expected to occur before mid-century.

U.S. Regional Effects

Climate change is bringing different types of challenges to each region of the country. Some of the current and future impacts are summarized below. These findings are from the Third 3 and Fourth 4 National Climate Assessment Reports, released by the U.S. Global Change Research Program .

  • Northeast. Heat waves, heavy downpours, and sea level rise pose increasing challenges to many aspects of life in the Northeast. Infrastructure, agriculture, fisheries, and ecosystems will be increasingly compromised. Farmers can explore new crop options, but these adaptations are not cost- or risk-free. Moreover, adaptive capacity , which varies throughout the region, could be overwhelmed by a changing climate. Many states and cities are beginning to incorporate climate change into their planning.
  • Northwest. Changes in the timing of peak flows in rivers and streams are reducing water supplies and worsening competing demands for water. Sea level rise, erosion, flooding, risks to infrastructure, and increasing ocean acidity pose major threats. Increasing wildfire incidence and severity, heat waves, insect outbreaks, and tree diseases are causing widespread forest die-off.
  • Southeast. Sea level rise poses widespread and continuing threats to the region’s economy and environment. Extreme heat will affect health, energy, agriculture, and more. Decreased water availability will have economic and environmental impacts.
  • Midwest. Extreme heat, heavy downpours, and flooding will affect infrastructure, health, agriculture, forestry, transportation, air and water quality, and more. Climate change will also worsen a range of risks to the Great Lakes.
  • Southwest. Climate change has caused increased heat, drought, and insect outbreaks. In turn, these changes have made wildfires more numerous and severe. The warming climate has also caused a decline in water supplies, reduced agricultural yields, and triggered heat-related health impacts in cities. In coastal areas, flooding and erosion are additional concerns.

A Degree of Difference

So, the Earth's average temperature has increased about 2 degrees Fahrenheit during the 20th century. What's the big deal?

tourism harmful effects

What’s the difference between climate change and global warming?

“Global warming” refers to the long-term warming of the planet. “Climate change” encompasses global warming, but refers to the broader range of changes that are happening to our planet, including rising sea levels; shrinking mountain glaciers; accelerating ice melt in Greenland, Antarctica and the Arctic; and shifts in flower/plant blooming times.

tourism harmful effects

Is it too late to prevent climate change?

Humans have caused major climate changes to happen already, and we have set in motion more changes still. However, if we stopped emitting greenhouse gases today, the rise in global temperatures would begin to flatten within a few years. Temperatures would then plateau but remain well-elevated for many, many centuries.

The rise of space tourism could affect Earth's climate in unforeseen ways, scientists worry

Are the effects of rocket launches on the atmosphere really negligible?

Hybrid rocket motors such as those used in Virgin Galactic's rocket planes emit a lot of soot.

Scientists worry that growing numbers of rocket flights and the rise of space tourism could harm Earth's atmosphere and contribute to climate change. 

When billionaires Richard Branson and Jeff Bezos soared into space this month aboard their companies' suborbital tourism vehicles, much of the world clapped in awe. 

But for some scientists, these milestones represented something other than just a technical accomplishment. Achieved after years of delays and despite significant setbacks , the flights marked the potential beginning of a long-awaited era that might see rockets fly through the so-far rather pristine upper layers of the atmosphere far more often than they do today. In the case of SpaceShipTwo, the vehicle operated by Branson's Virgin Galactic, these flights are powered by a hybrid engine that burns rubber and leaves behind a cloud of soot.

"Hybrid engines can use different types of fuels, but they always generate a lot of soot," said Filippo Maggi, associate professor of aerospace engineering at Politecnico di Milano, Italy, who researches rocket propulsion technologies and was part of a team that several years ago published an extensive analysis of hybrid rocket engine emissions. "These engines work like a candle, and their burning process creates conditions that are favorable for soot generation."

According to Dallas Kasaboski, principal analyst at the space consultancy Northern Sky Research, a single Virgin Galactic suborbital space tourism flight, lasting about an hour and a half, can generate as much pollution as a 10-hour trans-Atlantic flight. Some scientists consider that disconcerting, in light of Virgin Galactic’s ambitions to fly paying tourists to the edge of space several times a day.

"Even if the suborbital tourism market is launching at a fraction of the number of launches compared to the rest of the [tourism] industry, each of their flights has a much higher contribution, and that could be a problem," Kasaboski told Space.com.

Virgin Galactic's rockets are, of course, not the only culprits. All rocket motors burning hydrocarbon fuels generate soot, Maggi said. Solid rocket engines, such as those used in the past in the boosters of NASA's space shuttle , burn metallic compounds and emit aluminum oxide particles together with hydrochloric acid, both of which have a damaging effect on the atmosphere.

The BE-3 engine that powers Blue Origin's New Shepard suborbital vehicle, on the other hand, combines liquid hydrogen and liquid oxygen to create thrust. The BE-3 is not a big polluter compared to other rocket engines, emitting mainly water along with some minor combustion products, experts say .

Too little is known

For Karen Rosenlof, senior scientist at the Chemical Sciences Laboratory at the U.S. National Oceanic and Atmospheric Administration (NOAA), the biggest problem is that rockets pollute the higher layers of the atmosphere — the stratosphere, which starts at an altitude of about 6.2 miles (10 kilometers), and the mesosphere, which goes upward from 31 miles (50 km). 

"You are emitting pollutants in places where you don't normally emit it," Rosenlof told Space.com. "We really need to understand. If we increase these things, what is the potential damage?"

So far, the impact of rocket launches on the atmosphere has been negligible, according to Martin Ross, an atmospheric scientist at the Aerospace Corporation who often works with Rosenlof. But that's simply because there have not been that many launches. 

"The amount of fuel currently burned by the space industry is less than 1% of the fuel burned by aviation," Ross told Space.com. "So there has not been a lot of research, and that makes sense. But things are changing in a way that suggests that we should learn about this in more detail."

Northern Sky Research predicts that the number of space tourism flights will skyrocket over the next decade, from maybe 10 a year in the near future to 360 a year by 2030, Kasaboski said. This estimate is still far below the growth rate that space tourism companies like Virgin Galactic and Blue Origin envision for themselves. 

"Demand for suborbital tourism is extremely high," Kasaboski said. "These companies virtually have customers waiting in a line, and therefore they want to scale up. Ultimately, they would want to fly multiple times a day, just like short-haul aircraft do."

The rate of rocket launches delivering satellites into orbit is expected to grow as well. But Kasaboski sees bigger potential for growth in space tourism. 

"It's like the difference between a cargo flight and a passenger flight," Kasaboski said. "There's a lot more passengers that are looking to fly."

The problem is, according to Ross, that the scientific community has no idea and not enough data to tell at what point rocket launches will start having a measurable effect on the planet's climate. At the same time, the stratosphere is already changing as the number of rocket launches sneakily grows.

"The impacts of these [rocket-generated] particles are not well understood even to an order of magnitude, the factor of 10," Ross said. "The uncertainty is large, and we need to narrow that down and predict how space might be impacting the atmosphere."

Space shuttle's ozone holes 

So far, the only direct measurements of the effects of rocket launches on chemical processes in the atmosphere come from the space shuttle era. In the 1990s, as the world was coming together to salvage the damaged ozone layer , NASA, NOAA and the U.S. Air Force put together a campaign that looked at the effects of the emissions from the space shuttle's solid fuel boosters on ozone in the stratosphere. 

"In the 1990s, there were significant concerns about chlorine from solid rocket motors," Ross said. "Chlorine is the bad guy to ozone in the stratosphere, and there were some models which suggested that ozone depletion from solid rocket motors would be very significant."

The scientists used NASA's WB 57 high-altitude aircraft to fly through the plumes generated by the space shuttle rockets in Florida. Reaching altitudes of up to 60,000 feet (19 km), they were able to measure the chemical reactions in the lower stratosphere just after the rockets' passage. 

"One of the fundamental questions was how much chlorine is being made in these solid rocket motors and in what form," David Fahey, the director of the Chemical Sciences Laboratory at NOAA, who led the study, told Space.com. "We measured it several times and then analyzed the results. At that time, there were not enough space shuttle launches to make a difference globally, but locally one could deplete the ozone layer due to this diffuse plume [left behind by the rocket]."

The space shuttle retired 10 years ago, but rockets generating ozone-damaging substances continue launching humans and satellites to space today. 

In fact, in 2018, in its latest Scientific Assessment of Ozone Depletion , which comes out every four years, the World Meteorological Organization included rockets as a potential future concern. The organization called for more research to be done as the number of launches is expected to increase.  

Worse than geoengineering 

Rosenlof's team studies the broader effects of human-made substances in the higher layers of the atmosphere using powerful NOAA supercomputers. The work is akin to predicting the proverbial butterfly effect, the influence of minuscule changes in the chemistry of the air tens of miles above Earth on climate and weather patterns on the ground. For her, black carbon, or soot, emitted by rockets burning hydrocarbon fuels, is of particular concern.

"The problem with soot is that it absorbs ultraviolet light, and that means that it could heat the stratosphere," Rosenlof said. "When you start heating the stratosphere, the layer above the troposphere [closest to the ground], you start changing the motion in the stratosphere. You are changing the energy transfer, and that could actually affect what is happening on the ground."

Rosenlof points out that many of the particles generated by some rockets have been of interest to scientists due to the possible effects they could have on the global climate in a different context — that of geoengineering , the deliberate tampering with the atmosphere with the aim of stopping or mitigating global warming. 

Rosenlof recently co-authored a paper that used the same powerful NOAA supercomputers to model what the scientists call a climate intervention. The team was interested in the climate effects of dispersing sulfur dioxide particles, which are known to reflect light away from Earth, in combination with soot (which is also part of rocket emissions) in the lower stratosphere. Soot absorbs energy from sunlight and pushes the sulfur dioxide aerosol particles to a higher altitude by warming up the surrounding air. At that higher altitude, the sulfur dioxide can start its climate-cooling work. The experiment modeled what would happen when 1.1 million tons of sunlight-reflecting sulfur dioxide mixed with 11,000 tons of black carbon were released in the upper troposphere by aircraft over a 10-day period. 

The study didn't find any significant negative effects on weather on Earth. Yet, those results do not dispel Rosenlof's concerns about the possible risks associated with the growing number of rocket launches. 

Altering the jet stream

"Black carbon in the geoengineering experiment that we did isn't as high as the stuff from these rockets," she said. "The problem is that the higher you go, the longer something lasts. Neither of them is ideal, because either of them would produce heating in places where we don't have heating right now."

According to Maggi, the soot particles generated by hybrid rocket engines are extremely small and light-weight. In fact, when he and his colleagues tried to measure the soot output of hybrid rocket engines in a laboratory, they couldn't reliably do it with precision because of the particles' minuscule size. 

"We were able to measure the particle output from solid rocket motors," Maggi said. "These are about a micron in size, and there [are] a lot of them. But because they are large, they fall to the ground more quickly. In hybrid rocket engines, we were not able to collect the soot from the plume because it's extremely fine, a few nanometres in size."

Maggi fears these particles could, in fact, stay in the stratosphere forever.

"They have the same size as the carbon emitted by aircrafts," Maggi said. "And we know that there is a layer of carbon in the atmosphere at the flight level of aircrafts which is staying there. It's very likely that particles coming from rocket motors will do the same."

The accumulation of these particles over years and decades is what worries the scientists. Just as the current climate crisis started relatively slowly as the amount of carbon released into the atmosphere grew, the pollution in the stratosphere may only start causing harm some years down the road.

Rosenlof added that in the long term, injecting pollutants into the stratosphere could alter the polar jet stream, change winter storm patterns or affect average rainfall. 

"You might go from 25 inches [64 centimeters] a year to 20 inches [51 cm] a year in some places, which maybe doesn't sound like that big of a deal unless you are a farmer trying to grow your wheat right there," Rosenlof said. "Then a subtle change in rainfall can impact your crop yields."

Work to be done 

For this reason, Fahey says, it is critical that scientific work starts now to evaluate the future risks. 

"There is this fundamental gap where we just don't have the numbers, and that means that the science is limited because we have this lack of information," he said. "We feel it is part of our responsibility [at NOAA] to assess the impact of human activity on the stratosphere. Rockets are a principal and unique source [of stratospheric pollution], the launch frequencies are increasing and the effects are accumulating."

Fahey envisions a wider research program that would analyze the emissions and impacts of individual types of rocket engines and fuels on the stratosphere. The data could be used in Rosenlof's models to better predict the effects in accordance with the expected growth of the number of launches. Fahey, however, says that a political decision would have to come first to provide NOAA and its partners with funding that would enable them to take the high-altitude aircraft to the sky again and gather the data. The good news is, he added, that the U.S. Congress seems to be aware of the problem and things might soon start to move. 

"We would like to see a national program run by NOAA or the Air Force that would develop a database with basic emission characteristics of modern propulsion systems based on observations," he said. "We could gather some data in ground tests but also in the same way that we did with the space shuttle — by flying through the plumes just after launch."
