The Sahel is a semi-arid belt of land in Africa south of the Sahara and north of the wetter areas to the south. The Sahel extends east from the Atlantic Ocean through northern Senegal, southern Mauritania, Mali, Burkina Faso, southern Niger, northeastern Nigeria, Chad and the Sudan. Most of the Sahel region consists of savannah.
