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

TL;DR

This paper presents an agent-based modeling tool to evaluate the combined ecological and socio-economic impacts on coral reef systems, aiding decision-making amid climate change and human activity disruptions.

Contribution

It introduces a flexible multi-agent model integrating trophic and human interactions, adaptable to various ecological and geographical contexts.

Findings

Model generates spatial, temporal, and global impact data.

Tool can be adapted to different ecological and economic scenarios.

Provides insights into socio-ecological dynamics of coral reefs.

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.
