The development of ecotourism should go hand in hand with a certain level of sustainability as this approach makes it possible to create new, future-oriented vacation opportunities. It also offers new ideas and suggestions for the Conference in Rio as well as for the follow-up conferences on environmentally, socially, and economically compatible development (AGENDA 21, Biodiversity Convention, etc.). However, considering the existing variety of interests it is very difficult to answer the question about the specific needs of one generation. And so far, sustainability has hardly ever been found in regional tourist development. Several more extensive indicators for sustainability have only existed for a short period of time – as described in our study on the indicators for the evaluation of sustainability – and have yet to be implemented.
