Sustainability is a central term in today's political rhetoric. At the same time, sustainable development is one of the notions which mainly base on an intuitive public understanding and mark ideas almost nobody would deny. Thus, even in scientific discourse and particularly in tourism the term 'sustainability' is often being used without scrutiny.This volume by Jörn W. Mundt contributes to a deeper understanding of the concept of sustainability by- providing a closer look at the original definition and- reviewing its conceptual history which helps to untangle the terminological confusion.Finally, the book demonstrates that 'sustainable tourism' cannot be a political objective in its own right and is only achievable within the context of an overall sustainable economy.
