Evaluation of the cumulated impacts on the marine resource of a socio-ecological coral system: approach by agent-based modeling

Abstract

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.
