  In the context of climate change and significant changes in human activities
around the world, coral reefs are subject to many disruptions. We develop here
a tool to help decision-making in Moorea (French Polynesia), based on
multi-agent modeling. We model the trophic interactions with a Lotka-Volterra
model, and also the interactions between fishermen, trophic groups and tourist
operators. The results are generated through global, temporal (time series),
and spatial (GIS maps) outputs. The model produced here can be transposed to
other ecological and economic situations, and other geographical areas, by
modifying the parameters and changing the input map data.
