Abstract

Due to their isolation, limited resources and high population density, small islands are particularly vulnerable to multi-sectoral crises. The study of the sustainability of small island social and environmental development raises among others the challenge of balanced uses of local resources, including water, food and energy. Aspects of this are currently investigated through so called models of the Water-Energy-Food (WEF) nexus. In this paper we propose a novel approach of the WEF nexus through the optimization of scenarios that make use of Geographical Information Systems (GIS) integrated with robust optimization models coined in Operations Research. Our contribution allows the identification of trade-offs between future land use potentials and thresholds by maximizing a food Self-Sufficiency Ratio (SSR) by 2035. We show a case study of our approach on Reunion island, based on real data. Our results show through different scenarii of land use dynamics, the potential of this model as a decision-support tool.
