Resumo: | Coastal areas are complex socio-ecosystem where ecological, human and decisional compounds show multiple and reciprocal relationships. Because of the growth of population and tourism sector, coastal areas are permanently threatened through increase of recreational uses and diversification of related activities. To better understand coastal areas functioning, it is necessary to take into account uses and their management. Monitoring data over a ten years period revealed that recreational uses greatly increased especially within Marine Protecting Areas (MPA), during week-end days and warm season resulting to higher and more frequent frequentation peaks. While, practices within MPA are managed to decrease impacts, pressures associated with recreational uses are higher because of the concentration of users within MPA. As a consequence, ecological state decrease and social carrying capacity has been reached in several sites. Environmental quality is an important feature of satisfaction for recreational users but their activity lead to ecological impacts on fish, bird and habitat diversity of reef ecosystems. In addition, users. concentration and the diversification of sometimes conflicting practices decrease quality of experience of users and can lead to their displacement to other sites. As a consequence, pressures spread to less accessible sites, often not regulated and thus more threatened. Results allowed defining a model describing relationship between biodiversity, uses and management response. This model was used to test management scenarios, useful for integrated coastal area management and for identify knowledge gaps.
