Etude de l'éco-sociosystème du Parc National du Banc d'Arguin : vers une régulation des dynamiques halieutiques imraguen

Abstract : Created in 1976, the Banc d'Arguin National Park (PNBA) is a marine protected area classified as a World Heritage Site by UNESCO. The park is home to a fishing population called "Imraguen" formerly living from a traditional subsistence fishery. Over the last twenty years, fishing at the Banc d'Arguin has become a highly lucrative commercial activity leading to increased losses of a rich marine biodiversity.The thesis focuses on the understanding of the fish dynamics that have been implemented in the park since its creation. Based on the concept of the fishing system, the study proposes to describe and analyze the interactions between the ecosystem and the socio-system in its social, cultural, spatial, political, economic and regulatory dimensions. Therefore, the approach is intended to be systemic and focuses on understanding the fishery dynamics of the Banc d'Arguin as a whole.This thesis aims to rethink the management strategies of the park by trying to reduce pressure on the fishery resource. Ultimately, the results of this research will have to serve as a decision-making tool for the manager.
