Socio-Cultural and Environmental Impacts of Tourism

The socio-cultural impacts of tourism are the effects on the way of life, traditions, values and communities of host populations, and the environmental impacts are the effects on land, water, air, wildlife and climate; both can be positive or negative. In brief: benefits include jobs, income, funding for conservation and heritage and cultural exchange. Costs include crowding, rising prices, loss of authenticity, pollution, damage to ecosystems and greenhouse gas emissions, which are estimated at roughly 5–8% of the global total including transport. Good planning, regulation and community involvement can increase the benefits and reduce the costs.

The balance of impacts differs between places and depends on the type and scale of tourism and on how it is managed. This guide explains the social and cultural impacts, the environmental impacts, ways to reduce harm, compares positive and negative effects in a table, works through calculations, outlines how awareness developed and corrects common mistakes.

What are the socio-cultural impacts?

Positive impacts

• Jobs and income: work for local people, including women and young people, and support for small businesses and crafts.
• Preservation of heritage and traditions: income from visitors pays for restoring monuments, and interest from tourists can revive crafts, music and festivals.
• Better infrastructure and services: roads, airports, water supply and health services built for tourists also serve residents.
• Cultural exchange and understanding: contact between people of different backgrounds can reduce prejudice.

Negative impacts

• Commodification and loss of authenticity: ceremonies and crafts are changed to suit tourists’ tastes, or staged for performance, and may lose their meaning.
• Demonstration effect: local people, particularly young people, may copy visitors’ dress, behavior and consumption, which can cause tensions with traditions.
• Crowding, noise and conflict: residents may feel that their town is overrun, and the behavior of some tourists causes offense.
• Rising costs and displacement: demand for property raises prices and rents, and short-term rentals reduce housing for residents, as in Barcelona, Lisbon and Amsterdam.
• Inequality and low pay: jobs may be seasonal, low-paid and insecure, with senior positions going to outsiders, and local people may lose access to beaches or land.
• Crime, exploitation and health: in some places, tourism is linked to crime, child labor, sexual exploitation and the spread of disease.

Doxey’s Irridex (1975) describes how the attitude of residents may change as tourism grows, from euphoria (welcome) to apathy, annoyance and antagonism.

What are the environmental impacts?

• Land and habitats: clearing land for hotels, golf courses and ski runs destroys vegetation, and footpaths are eroded by walkers. Trampling damages dunes, alpine plants and soils.
• Water use and pollution: tourists often use far more water than residents, for pools, showers and golf courses, which can cause shortages in dry destinations. Untreated sewage and waste from hotels and cruise ships pollute rivers and seas.
• Marine and coastal damage: boat anchors and divers break corals, sunscreen chemicals are suspected to harm reefs, and beaches are eroded by coastal development. Maya Bay in Thailand was closed to visitors from 2018 to 2022 to let the corals recover.
• Wildlife disturbance: noise and crowds disturb breeding and feeding, and feeding wildlife changes behavior. The trade in souvenirs from endangered species is a further threat.
• Waste: litter, plastic and waste on popular trails and mountains, such as the rubbish left on Mount Everest.
• Air pollution and climate change: aircraft, cars and cruise ships emit carbon dioxide and other pollutants. A study published in 2018 estimated that tourism accounts for around 8% of global greenhouse gas emissions, though estimates vary with the method used. Climate change, in turn, threatens destinations, for example through coral bleaching, melting glaciers and sea-level rise.

How can impacts be managed?

Measures include planning and zoning (limiting development in sensitive areas), visitor management (permits, quotas, entry fees, timed tickets, boardwalks and marked trails), regulation and standards (waste treatment, building rules and limits on short-term rentals), pricing and taxes that fund conservation, community involvement so that local people share in decisions and income, education of visitors with codes of conduct, certification schemes for green hotels and operators, and reducing travel emissions by encouraging rail, longer stays and offsetting. The term sustainable tourism describes tourism that takes full account of its current and future economic, social and environmental impacts.

Positive and negative impacts compared

Worked example: water, emissions and trails

The figures are hypothetical and illustrate typical calculations.

1. Water use: a resort has 800 guests, each using 400 liters per day. The daily use is 800 × 400 = 320,000 liters. Local residents use 120 liters per day each, so the resort uses as much as 320,000 ÷ 120 = 2,667 residents.
2. Annual water: 320,000 liters × 365 = 116,800,000 liters, or 116,800 m³ per year.
3. Flight emissions: a return flight of 8,000 km in total, with emissions of about 0.15 kg CO₂ per passenger-km, produces 8,000 × 0.15 = 1,200 kg, or 1.2 tonnes of CO₂ per passenger. For 50,000 visitors, the total is 50,000 × 1.2 = 60,000 tonnes.
4. Emissions by length of stay: a 3-night trip with 1.2 tonnes from the flight has 0.4 tonnes per night, while a 12-night trip has 0.1 tonnes per night, four times less per night for the same flight.
5. Trail erosion: a trail of 5 km (5,000 m) and 1.5 m width has an area of 7,500 m². If 80,000 walkers use it in a year, that is 80,000 ÷ 7,500 = 10.7 walkers per m² of trail surface. If managers decide that the surface can only take 5 walkers per m² a year (an illustrative threshold), the cap would be 5 × 7,500 = 37,500 walkers a year.
6. Housing: a city of 500,000 people has 12,000 homes used as short-term holiday rentals. If each home could house 2.3 residents, 12,000 × 2.3 = 27,600 people could live in them, about 5.5% of the population.

How has awareness of impacts developed?

In the 1960s and 1970s, the rapid growth of mass tourism in the Mediterranean and the Caribbean brought concerns about environmental damage and cultural change. Academic studies of the “host-guest” relationship started in the 1970s, including Doxey’s Irridex (1975) and Butler’s tourism area life cycle (1980). The Brundtland Report (1987) and the 1992 Rio Earth Summit promoted the idea of sustainable development, and the term “sustainable tourism” and the first ecotourism standards followed. The Global Code of Ethics for Tourism was adopted by the UN World Tourism Organization in 1999. In the 21st century, concerns about climate change, overcrowding and the effects of the pandemic have led to calls to “rebuild better.”

Which mistakes are common?

Mistake 1: Seeing tourism as only good or only bad

Impacts depend on scale, type and management, and affect different groups differently.

Mistake 2: Blaming tourists alone

Governments, developers, operators and local decision-makers also shape impacts through planning, regulation and business models.

Mistake 3: Forgetting the transport emissions

A green hotel can still be part of a high-carbon trip if the journey is by long-haul flight.

Mistake 4: Assuming that cultural change is always a loss

Cultures change by themselves. The concern is when change is imposed or when communities lose control over how their culture is presented.
