<P> The Sahel (/ səˈhɛl /) is the ecoclimatic and biogeographic zone of transition in Africa between the Sahara to the north and the Sudanian Savanna (historically known as the Sudan region) to the south . Having a semi-arid climate, it stretches across the south - central latitudes of Northern Africa between the Atlantic Ocean and the Red Sea . The name is derived from the Arabic word sāḥil (ساحل, Arabic pronunciation: (ˈsaːħil)) meaning "coast" or "shore" in a figurative sense (in reference to the southern edge of the vast Sahara), while the name Swahili means "coastal (dweller)" in a literal sense . </P> <P> The Sahel part of Africa includes (from west to east) parts of northern Senegal, southern Mauritania, central Mali, northern Burkina Faso, the extreme south of Algeria, Niger, the extreme north of Nigeria, central Chad, central and southern Sudan, the extreme north of South Sudan, Eritrea, Cameroon, Central African Republic and extreme north of Ethiopia . </P>
