This article studies the territorial dynamics linked to the establishment of marine protected areas in the lagoon of Moorea. The establishment of these specific zones involves a double process, of “deterritorialization” and “re-territorialization” (Deleuze and Guattari, 1980). This double dynamic is historical, induced by previous events taking place in the evolution of a population or a territory. This article shows the nature of the issues that arise around the creation of marine protected areas and the logics of actors that endure or emerge.
