The aim of this paper is to build a theoretical framework and to use an empirical test to outline the links between climate change, migrations and remittances. More precisely, we show theoretically how remittances could fight the rural exodus and international migration resulting from climatic variations under certain assumptions. The theoretical hypotheses are in line with the literature about climatic migrations and especially Marchiori et al. (2012)’s article. Finally, we propose an econometric panel analysis (fixed effects and double least squares models) based on two different sets of data.
