Tourism is the world’s fastest growing industry, and impacts globally upon ecology, economies, peoples, cultures and the built environment. Development, therefore, must be sustainable and sympathetic in order to preserve the environment and culture it exploits. Despite sustainable tourism being an area of considerable recent interest, there has been no synthesis of the diverse considerations of sustainable tourism, and the language and terms particular to this subject. An important resource for researchers of tourism, this reference work defines and explains terms associated with considering and preserving the environment, host peoples, communities, cultures, customs, lifestyles and social and economic systems.
