Abstract
This thesis study the case of French Guiana where both the small-scale fishery and the mangrove play major ecological and economic roles and face major uncertainties including climate change and demographic growth. More specifically, there will develop ecological-economic models calibrated on historical data provided by the LEEISA, derive different scenarios, management strategies and public policies from these dynamic models and compare the ecological-economic performances of these projections in terms of resilience management and the 3Rs.The ecological-economic evaluation under consideration will combine scores of biodiversity, ecosystem services and economic development.
