Coastal social-ecological systems worldwide are increasingly shaped by humans and natural stressors as they are facing unprecedented changes from the local to global levels. The Project INTHENSE aims to understand the effect of those stressors to help management and decision-making. From the case study of Moorea Island, French Polynesia, we developed a participatory approach using Bayesian Network modelling in order to understand the main consequences of natural and anthropogenic disturbances on the provision of two main ecosystems services (e.g. food provision and recreational services) provided by the lagoon.The development of such models is trans-disciplinary by essence and will have strong implications to guide the adaptability and/or transformability of uses of Moorea lagoon to sustainably derive goods and services in face of regional and global changes.
