The objectives of the project are to unite regional research forces in the areas of ecosystem management by proposing strategies for the sustainable exploitation of resources, and then to transfer to the socio-economic world, strengthening the links undertaken/research laboratories. The quality of key coastal resources, understanding the dynamics of degradation of the quality of the resource, and the proposal of sustainable management compromises will be realised in a context of global change. In addition, new wealth in biodiversity will be sought in order to reveal remarkable biological properties opening up opportunities for innovation (cosmetics, agri-food, pharmaceuticals).
