In this bachelor thesis was researched the development of sustainable tourism in a special category of the developing countries, which is called Small Island Developing States. The concept of sustainable tourism is on the rise in recent years, trying to fight with mass tourism and its negative effects. Work is structured into two theoretical and two practical chapters, which include specific examples of use of sustainable tourism in the Caribbean, the Maldives and Cape Verde and their evaluation. The main aim of the thesis was to answer the question whether the use of sustainable tourism could improve the economic situation in developing countries and improve the living conditions of the population. It was concluded that sustainable tourism can improve living conditions, but residents have to engage in process of development. The economic situation in developing countries could be improved too, but local governments have to support this development and create the necessary conditions.
