The project aims to increase fishermen’ support to MPAs and to actively involve them in the conservation efforts and in the sustainable use of the marine resources of Caribbean MPAs. The assessment can be used to develop a system of payment for ecosystem services and establish a transfer of money from the users towards the fishermen. The establishment of a scheme of payment for ecosystem services within a marine protected area project in Martinique and in two MPAs in Saba and the British Virgin Islands aims to promote such efforts by establishing a fund transfer from the users towards the fishermen. Beyond the financial aspects, the implementation of such a process intends to change the image related to the world of fisheries: rather than being considered as a destructive force of the marine environment, it would be seen as the guardian of its good health. The project is developing avenues in this direction so that the traditional knowledge of the fishermen is valued. It may also mark the stages for the implementation of payments for ecosystem services in MPAs in coastal areas in the Caribbean and in other parts of the world.
