As with other impacts, this massive economic development brings along both positive and negative consequences.
According to the World Tourism Organization, 698 million people traveled to a foreign country in 2000, spending more US$ 478 billion. International tourism receipts combined with passenger transport currently total more than US$ 575 billion - making tourism the world's number one export earner, ahead of automotive products, chemicals, petroleum and food.

NEGATIVE ECONOMIC IMPACTS OF TOURISM

There are many hidden costs to tourism, which can have unfavorable economic effects on the host community. Often rich countries are better able to profit from tourism than poor ones. Whereas the least developed countries have the most urgent need for income, employment and general rise of the standard of living by means of tourism, they are least able to realize these benefits. Among the reasons for this are large-scale transfer of tourism revenues out of the host country and exclusion of local businesses and products.

Leakage

The direct income for an area is the amount of tourist expenditure that remains locally after taxes, profits, and wages are paid outside the area and after imports are purchased; these subtracted amounts are called leakage. In most all-inclusive package tours, about 80% of travelers' expenditures go to the airlines, hotels and other international companies (who often have their headquarters in the travelers' home countries), and not to local businesses or workers. In addition, significant amounts of income actually retained at destination level can leave again through leakage.

A study of tourism 'leakage' in Thailand estimated that 70% of all money spent by tourists ended up leaving Thailand (via foreign-owned tour operators, airlines, hotels, imported drinks and food, etc.). Estimates for other Third World countries range from 80% in the Caribbean to 40% in India.

Of each US$ 100 spent on a vacation tour by a tourist from a developed country, only around US$ 5 actually stays in a developing-country destination's economy. The figure below shows how the leakage happens.

Diagram:  Leakages

There are two main ways that leakage occurs:

Import leakage This commonly occurs when tourists demand standards of equipment, food, and other products that the host country cannot supply. Especially in less-developed countries, food and drinks must often be imported, since local products are not up to the hotel's (i.e. tourist's) standards or the country simply doesn't have a supplying industry. Much of the income from tourism expenditures leaves the country again to pay for these imports.

The average import-related leakage for most developing countries today is between 40% and 50% of gross tourism earnings for small economies and between 10% and 20% for most advanced and diversified economies, according to UNCTAD.

Even in developed regions, local producers are often unable to supply the tourism industry appropriately even if good will is present: the 64-room hotel "Kaiser im Tirol" in Austria, an award-winning leader in sustainable practices, cannot find organic food suppliers in the local farming networks in the appropriate quantity, quality and reliability, as production cycles and processes are not compatible with its needs.

Export leakage Multinational corporations and large foreign businesses have a substantial share in the import leakage. Often, especially in poor developing destinations, they are the only ones that possess the necessary capital to invest in the construction of tourism infrastructure and facilities. As a consequence of this, an export leakage arises when overseas investors who finance the resorts and hotels take their profits back to their country of origin.

A 1996 UN report evaluating the contribution of tourism to national income, gross levels of incomes or gross foreign exchange, found that net earnings of tourism, after deductions were made for all necessary foreign exchange expenditures, were much more significant for the industry. This report found significant leakage associated with: (a) imports of materials and equipment for construction; (b) imports of consumer goods, particularly food and drinks; (c) repatriation of profits earned by foreign investors; (d) overseas promotional expenditures and (e) amortization of external debt incurred in the development of hotels and resorts. The impact of the leakage varied greatly across countries, depending on the structure of the economy and the tourism industry. From the data presented in this study on the Caribbean, St. Lucia had a foreign exchange leakage rate of 56% from its gross tourism receipts, Aruba had 41%, Antigua and Barbuda 25% and Jamaica 40%.

Enclave tourism

Local businesses often see their chances to earn income from tourists severely reduced by the creation of "all-inclusive" vacation packages. When tourists remain for their entire stay at the same cruise ship or resort, which provides everything they need and where they will make all their expenditures, not much opportunity is left for local people to profit from tourism.

The Organization of American States (OAS) carried out a survey of Jamaica's tourist industry that looked at the role of the all-inclusives compared to other types of accommodation. It found that 'All-inclusive hotels generate the largest amount of revenue but their impact on the economy is smaller per dollar of revenue than other accommodation subsectors.'

It also concluded that all-inclusives imported more, and employed fewer people per dollar of revenue than other hotels. This information confirms the concern of those who have argued that all-inclusives have a smaller trickle-down effect on local economies. (Source: Tourism Concern)

The cruise ship industry provides another example of economic enclave tourism. Non-river cruises carried some 8.7 million international passengers in 1999. On many ships, especially in the Caribbean (the world's most popular cruise destination with 44.5% of cruise passengers), guests are encouraged to spend most of their time and money on board, and opportunities to spend in some ports are closely managed and restricted.

Other negative impacts

Infrastructure cost
Tourism development can cost the local government and local taxpayers a great deal of money. Developers may want the government to improve the airport, roads and other infrastructure, and possibly to provide tax breaks and other financial advantages, which are costly activities for the government. Public resources spent on subsidized infrastructure or tax breaks may reduce government investment in other critical areas such as education and health.

Increase in prices
Increasing demand for basic services and goods from tourists will often cause price hikes that negatively affect local residents whose income does not increase proportionately. A San Francisco State University study of Belize found that, as a consequence of tourism development, the prices for locals increased by 8%.
 

Tourism development and the related rise in real estate demand may dramatically increase building costs and land values. Not only does this make it more difficult for local people, especially in developing countries, to meet their basic daily needs, it can also result in a dominance by outsiders in land markets and in-migration that erodes economic opportunities for the locals, eventually disempowering residents. In Costa Rica, close to 65% of the hotels belong to foreigners. Long-term tourists living in second homes, and the so-called amenity migrants (wealthy or retired people and liberal professionals moving to attractive destinations in order to enjoy the atmosphere and peaceful rhythms of life) cause price hikes in their new homes if their numbers attain a certain critical mass.

Economic dependence of the local community on tourism
Diversification in an economy is a sign of health, however if a country or region becomes dependent for its economic survival upon one industry, it can put major stress upon this industry as well as the people involved to perform well. Many countries, especially developing countries with little ability to explore other resources, have embraced tourism as a way to boost the economy.

In The Gambia, for instance, 30% of the workforce depends directly or indirectly on tourism. In small island developing states, percentages can range from 83% in the Maldives to 21% in the Seychelles and 34% in Jamaica, according to the WTO. Over-reliance on tourism, especially mass tourism, carries significant risks to tourism-dependent economies. Economic recession and the impacts of natural disasters such as tropical storms and cyclones as well as changing tourism patterns can have a devastating effect on the local tourism sector.

Malta has only 380,000 residents, but received 1.2 million tourists in 1999. As 25% of GDP (and indirectly 40% ), tourism generated more than $650 million in foreign exchange earnings. Malta's high dependence on tourism and a limited number of export products makes its trade performance vulnerable to shifts in international demand.

Seasonal character of jobs
The seasonal character of the tourism industry creates economic problems for destinations that are heavily dependent on it. Problems that seasonal workers face include job (and therefore income) insecurity, usually with no guarantee of employment from one season to the next, difficulties in getting training, employment-related medical benefits, and recognition of their experience, and unsatisfactory housing and working conditions.
 

Other industry impacts affecting tourism

Economic crises, like the Asian crisis that hit Thailand, Malaysia and Indonesia a few years ago, can be devastating to inbound tourism flows. The financial turmoil triggered a sharp fall in tourism flows to affected countries during 1997 and 1998. In the Philippines, the crisis and the temporary closure of Philippine Airlines affected inbound arrivals significantly as there was a decline of almost 3.3% in 1998.

HOW TOURISM CAN CONTRIBUTE TO ECONOMIC CONSERVATION
 

The main positive economic impacts of tourism relate to foreign exchange earnings, contributions to government revenues, and generation of employment and business opportunities. These are discussed briefly here; further information on economic contributions from tourism can be found at the World Travel & Tourism Council's home page.

Foreign exchange earnings
Tourism expenditures and the export and import of related goods and services generate income to the host economy and can stimulate the investment necessary to finance growth in other economic sectors. Some countries seek to accelerate this growth by requiring visitors to bring in a certain amount of foreign currency for each day of their stay and do not allow them to take it out of the country again at the end of the trip.

An important indicator of the role of international tourism is its generation of foreign exchange earnings. Tourism is one of the top five export categories for as many as 83% of countries and is a main source of foreign exchange earnings for at least 38% of countries.

Contribution to government revenues
Government revenues from the tourism sector can be categorized as direct and indirect contributions. Direct contributions are generated by taxes on incomes from tourism employment and tourism businesses, and by direct levies on tourists such as departure taxes. Indirect contributions are those originated from taxes and duties levied on goods and services supplied to tourists.

The United States National Park Service estimates that the 273 million visits to American national parks in 1993 generated direct and indirect expenditures of US$ 10 billion and 200,000 jobs. When visits to land managed by other agencies, and to state, local, and privately-managed parks, are added, parks were estimated to bring around US$ 22 billion annually to the US economy. These expenditures also generate significant tax revenues for the government.

The World Travel and Tourism Council estimates that travel and tourism's direct, indirect, and personal tax contribution worldwide was over US$ 800 billion in 1998 - a figure it expects to double by 2010. (Source: WTTC/Michigan State University Tax Policy Center)

Employment generation
The rapid expansion of international tourism has led to significant employment creation. For example, the hotel accommodation sector alone provided around 11.3 million jobs worldwide in 1995. Tourism can generate jobs directly through hotels, restaurants, nightclubs, taxis, and souvenir sales, and indirectly through the supply of goods and services needed by tourism-related businesses. According to the WTO, tourism supports some 7% of the world's workers.

Stimulation of infrastructure investment
Tourism can induce the local government to make infrastructure improvements such as better water and sewage systems, roads, electricity, telephone and public transport networks, all of which can improve the quality of life for residents as well as facilitate tourism.

Contribution to local economies
Tourism can be a significant, even essential, part of the local economy. As the environment is a basic component of the tourism industry's assets, tourism revenues are often used to measure the economic value of protected areas. For example, Dorrigo National Park in New South Wales, Australia, has been estimated to contribute 7% of gross regional output and 8.4% of regional employment. The importance of tourism to local economies can also be illustrated by the impacts when it is disrupted: the catastrophic 1997 floods that closed Yosemite National Park in California cause locally severe economic losses to the areas around the park. In the most heavily impacted county, Mariposa County, 1997 personal income was reduced by an estimated US$1,159 per capita (US$18 million for the entire county) - a 6.6% decline. The county was also estimated to have lost US$1.67 million in county occupancy and sales tax revenues, and 956 jobs, a significant number in a county of fewer than 16,000 residents.

There are other local revenues that are not easily quantified, as not all tourist expenditures are formally registered in the macro-economic statistics. Money is earned from tourism through informal employment such as street vendors, informal guides, rickshaw drivers, etc. The positive side of informal or unreported employment is that the money is returned to the local economy, and has a great multiplier effect as it is spent over and over again. The World Travel and Tourism Council estimates that tourism generates an indirect contribution equal to 100% of direct tourism expenditures.
