My thesis focuses on the problems of ecotourism, or more precisely its borders from an anthropological perspective, using example of a typical Cambodian community named Chambok. Based on five months of research, together with ethnographic methods of research I found out that boundaries of ecotourism are complex, multi-layered, problematic and negotiated and also that there are so called "grey zones" encompassing them. It is the conceptualization of these zones and boundaries, which is my contribution to current anthropological debate about ecotourism, which has been largely left out until now.
