The states of the western Sahel (Mauritania, Mali, Burkina Faso, Niger, Chad, and northern Nigeria) are politically quite fragile. Recent severe changes in climate are accelerating conflict and violence in an already economically desperate region, causing increased skirmishes between pastoralists and farmers, while depleting water resources and encouraging many to migrate either within the region or to North Africa. This article provides a commentary on the increasing levels of violent conflicts in the Western Sahel. Larémont explains the role of climate change, jihadist groups and the failing role of the state. It further critically analyses the interference of Western countries in this region.
