The subject of sustainability has become central to the discussion of how to succeed in the stable development of the tourism industry, due to the uncontrollable nature of supply and demand over the past few decades. Thus, this book examines policies and practices associated with the introduction of various methods in order to maintain sustainable tourism development. The list of policies and practices is based on a selection of the most recent topics, providing many real-world examples and cases in relation to culture and nature-based environmental issues, representing both individual businesses and tourist destinations with an international focus, namely Australia, Belgium, Bulgaria, Canada, Portugal, South Korea, Taiwan, Turkey, and the USA. Structured with 15 chapters altogether, the principles and guidelines discussed apply equally to different product levels in tourism such as museums, cities, regions, and countries. This volume is intended as a supplementary textbook for further reading. The editors believe that the book will gain attention from colleagues worldwide because of relevant educational courses on sustainable tourism, environmental tourism and cultural heritage management.
