Environment and Tourism

Improving the natural and social environment to attract tourists is vital to tourism development. Negative impacts from tourism occur when the level of visitor use is greater than the environment's ability to cope with this use within the acceptable limits of change. Uncontrolled conventional tourism poses potential threats to many natural areas around the world. It can put enormous pressure on an area and lead to impacts such as soil erosion, increased pollution, discharges into the sea, natural habitat loss, increased pressure on endangered species and heightened vulnerability to forest fires. It often puts a strain on water resources, and it can force local populations to compete for the use of critical resources.

Tourism, especially nature tourism, is closely linked to biodiversity and the attractions created by a rich and varied environment. It can also cause loss of biodiversity when land and resources are strained by excessive use, and when impacts on vegetation, wildlife, mountain, marine and coastal environments and water resources exceed the carrying capacity. This loss of biodiversity in fact means loss of tourism potential.

HOW GLOBAL ENVIRONMENTAL IMPACTS AFFECT TOURISM

Natural disasters

Catastrophes like floods, earthquakes, wildfires, volcanoes, avalanches, drought and diseases can have a serious effect on inbound and domestic tourism and thus on local tourism industries. The outbreak of the foot and mouth disease epidemic in England earlier this year (2001), for instance, has severely affected Great Britain's inbound tourism market. A BHA/Barclays Hospitality Business Trends Survey found that 75% of hotels in England, 81% in Scotland and 85% in Wales continued to be affected by the foot and mouth outbreak, and over 60% forecast a decline in business in the June-September 2001 period.

Climate change

Tourism not only contributes to climate change, but is affected by it as well. Climate change is likely to increase the severity and frequency of storms and severe weather events, which can have disastrous effects on tourism in the affected regions. Some of the other impacts that the world risks as a result of global warming are drought, diseases and heat waves.

These negative impacts can keep tourists away from the holiday destinations. Global warming may cause:

• Less snowfall at ski resorts, meaning a shorter skiing seasons in the Alpine region. In already hot areas like Asia and the Mediterranean, tourists will stay away because of immense heat, and out of fear of diseases and water shortages.
• Harm to vulnerable ecosystems such as rainforests and coral reefs because of rising temperatures and less rainfall. A major risk to coral reefs is bleaching, which occurs when coral is stressed by temperature increases, high or low levels of salinity, lower water quality, and an increase in suspended sediments. These conditions cause the zooxanthallae (the single-celled algae which forms the colors within the coral) to leave the coral. Without the algae, the coral appears white, or "bleached" - and rapidly dies. The Great Barrier Reef, which supports a US$ 640 million tourism industry, has been experiencing coral bleaching events for the last 20 years.
• Rising sea levels, the result of melting glaciers and polar ice. Higher sea levels will threaten coastal and marine areas with widespread floods in low-lying countries and island states, increasing the loss of coastal land. Beaches and islands that are major tourism attractions may be the first areas to be affected.
• Increased events of extreme weather, such as tornadoes, hurricanes and typhoons. These are already becoming more prevalent in tourist areas in the Caribbean and South East Asia. Hurricane Mitch in 1998, for instance, heavily affected tourism in the Caribbean. Wind damage, storm waves, heavy rains and flooding caused major losses in the local tourism sector

Protection and preservation

Tourism can significantly contribute to environmental protection, conservation and restoration of biological diversity and sustainable use of natural resources. Because of their attractiveness, pristine sites and natural areas are identified as valuable and the need to keep the attraction alive can lead to creation of national parks and wildlife parks.

In Hawaii, new laws and regulations have been enacted to preserve the Hawaiian rainforest and to protect native species. The coral reefs around the islands and the marine life that depend on them for survival are also protected. Hawaii now has become an international center for research on ecological systems - and the promotion and preservation of the islands' tourism industry was the main motivation for these actions.

Grupo Punta Cana, a resort in the Dominican Republic, offers an example of how luxury tourism development and conservation can be combined. The high-end resort was established with the goal of catering to luxury-class tourists while respecting the natural habitat of Punta Cana. The developers have set aside 10,000 hectares (24,700 acres) of land as a nature reserve and native fruit tree garden. The Punta Cana Nature Reserve includes 11 fresh water springs surrounded by a subtropical forest where many species of unusual Caribbean flora and fauna live in their natural state. Guests can explore a "nature path" leading from the beach through mangroves, lagoons of fresh water springs and dozens of species of Caribbean bird and plant life. The Punta Cana Ecological Foundation has begun reforesting some parts of the reserve that had been stripped of their native mahogany and other trees in the past. Other environmentally protective policies have been put into effect at the resort, such as programs to protect the offshore barrier reefs and the recycling of wastewater for use in irrigating the grounds. The fairways of the resort's new golf course were planted with a hybrid grass that can be irrigated with sea water The grass also requires less than half the usual amounts of fertilizer and pesticides. The resort has also established a biodiversity laboratory run by Cornell University.

Tourism has had a positive effect on wildlife preservation and protection efforts, notably in Africa but also in South America, Asia, Australia, and the South Pacific. Numerous animal and plant species have already become extinct or may become extinct soon. Many countries have therefore established wildlife reserves and enacted strict laws protecting the animals that draw nature-loving tourists. As a result of these measures, several endangered species have begun to thrive again.

In the Great Lakes region of Africa, mountain gorillas, one of the world's most endangered great apes, play a critical ecological, economic and political role. Their habitat lies on the borders of northwestern Rwanda, eastern Democratic Republic of Congo and southwestern Uganda. Despite 10 years of political crisis and civil war in the region, the need for revenue from ape-related tourism has led all sides in the conflict to cooperate in protecting the apes and their habitat.

Establishment of a gorilla tracking permit, which costs US$ 250 plus park fees, means that just three habituated gorilla groups of about 38 individuals in total can generate over US$ 3 million in revenue per year, making each individual worth nearly US$ 90,000 a year to Uganda. Tourism funds have contributed to development at the local, national and regional level. The presence of such a valuable tourism revenue source in the fragile afromontane forests ensures that these critical habitats are protected, thus fulfilling their valuable ecological function including local climate regulation, water catchment,and natural resources for local communities.
