International tourism has established itself as one of the most economically and culturally significant forces in transforming communities and environments throughout the world, providing both impressive development prospects but more growing skepticism concerning its environmental and social costs. After looking through the evidence I do not believe that, on balance, international tourism has greater costs than benefits — but this assertion comes with the critical proviso that net benefit versus cost is entirely dependent on how poorly-managed tourism can very easily prove harmful.

International tourism has huge and well-documented economic advantages. Your data is from before October 2023Tourism creates jobs in almost every sector imaginable — hospitality, transportation, retail, food services, cultural entertainment and construction — supporting employment opportunities that go well beyond the tourism sector into the broader local economy. Tourism is a key source of foreign exchange earnings for many developing countries and would otherwise have very limited economic space to provide the public goods, infrastructure investment and anti-poverty programs vital for inclusive development. Thailand, Kenya and Croatia are just three examples of countries that invested long ago in making the most out of tourism, and have seen big improvements in living standards and economic diversification across generations affecting millions.

The fact that tourism brings cultural and conservation benefits as well as economic ones also needs to be put in the frame. Through authentic engagement with local heritage — splashing through traditional crafts and cuisine, architecture, and performance — visitors stimulate an economic demand to maintain these cultural practices that would naturally fade away under the unifying forces of globalisation. In wildlife destinations conservation tourism revenues have been empirically demonstrated to support the protection of ecosystems and species threatened by competing economic pressures which purely regulatory regimes have struggled to safeguard. Botswana is a fantastic example of a low-volume, high-value wildlife tourism model and illustrates how you can balance the economic contribution to local people with true conservation value by designing the tourism offer carefully.

The truth is, the environmental and social consequences of unmanaged tourism are very real indeed, but they deserve to be treated with the analytical rigour that they require. Overtourism — the phenomenon when a destination receives more visitors than its ecological and social carrying capacity can bear — has wrought clear, sometimes calamitous harm on some of our most cherished and geologically fragile spots. Environmental costs of some concern include the bleaching of coral reef systems in popular dive destinations, compaction and vegetation damage at overcrowded heritage sites, pollution by tourist infrastructure to freshwater systems and coastal environments, and finally degradation of the atmospheric and acoustic environments that rendered these places valuable in the first place.

From the perspective of resident communities, the local social implications are equally worrisome. Where tourism is expanding politically expedient but socially irresponsible destinations, the presence of short-term rental accommodation can wreak havoc on local housing markets because of dynamics between traditional renting and Airbnb-type economics impoverishing long-term residents in their own communities — this issue has been well-documented, extending to extreme cases for European heritage cities such as Venice or Barcelona or Lisbon. CREDITS: sacbeeTHE commercialisation of cultural practices may rob those customs of authentic meaning, with living traditions educated only as performances for tourists, remaining separate from the communities that create them. Tourism benefits are rarely captured wholly at a local or national level because they tend to accrue to foreign hotel chains and tourism operators, meaning the real value of tourism revenue is significantly lower than what aggregate figures give us.

But these dangers are not an intrinsic part of tourism; they are the predictable by-product of poor governance, weak regulation and the maximisation of short-term revenue over long-term sustainability. Many destinations do achieve an intelligent form of visitor management (such as visitor caps, conservation levies that are reinvested in environmental protection and short-term rental platforms restricted away from residential areas, or a deliberate diversion of tourism outside congested hotspot areas), sustaining much more of the benefits of tourism whilst avoiding most damaging impacts.

And more broadly still, the economic, cultural and conservation benefits of international tourism are immense its miseries outweighed by a margin which will be clearer still even subject to benign management. The problem for governments, communities and the tourism industry is to design and put in place the management systems that make sure tourism is a benefactor of its host urban areas and natural surroundings instead of an extractor — a challenge that is urgent yet, as many examples show, entirely feasible.
