All forms of tourism have impacts on the natural environment. The impacts of ecotourism tend to be concentrated in areas of the highest conservation value, hence the need to manage and minimize these. This comprehensive text considers the impact of off-road vehicles, recreational boats and activities such as hiking and camping on destination areas, as well as impacts particular to specific ecosystems such as marine, polar and mountain environments. It incorporates reviews of extensively studied impacts by well-known experts as well as recent research. Now in paperback, this book will be an essential resource for tourism students, as well as researchers and industry practitioners.
