Sahel

The Sahel is the ecoclimatic and biogeographic zone of transition between the Sahara desert in the North and the Sudanian Savannas in the south. It stretches across the north of the African continent between the Atlantic Ocean and the Red Sea. The Arabic word sāḥil ساحل literally means "shore, coast", describing the appearance of the vegetation of the Sahel as a coastline delimiting the sand of the Sahara.

The Sahel covers parts of the territory of (from west to east) Northern part of Senegal, southern part of Mauritania, middle part of Mali, southern part of Algeria and Niger, middle part of Chad, southern part of Sudan, northern part of South Sudan and Eritrea. It is bordered on the north by the Sahara and on the south by the less arid savannah.
