My research paper deals with use conflicts in tourism (such as conflicts over natural ressources, social conflicts due to tourism), and I'm trying to find some articles / books about the creation of these conflicts. I would like to focus on one part on the fact that maybe some conflicts existed before the development of tourism, and tourism made them worst. I am wondering if tourism is not more like the straw that broke the camels back, than the real reason that provoked the emergence of conflicts.
