Climate change and Migration in the sahelian zone of Chad

Abstract

Climate change has become a world phenomenon nowadays. It affects all countries and leads to a thinning of natural resources and food in security, which in turn causes migrations of populations towards other horizons. The phenomenon is accentuated in desert regions and in the Sahel. The story of Chad is also characterized by periods of droughts that mark the collective memory. If the first migrations aimed to occupy the emerging land of the Lake Chad basin, the latest consequences of droughts and/or desertification pose major problems because they are a source of conflict in Chad.
