The Sahel region stretches from the Atlantic Ocean to the Red Sea and consists, according to the UN, of ten countries which sit, wholly or partly, within it: Senegal,  Gambia, Mauritania, Guinea, Mali, Burkina Faso, Niger, Chad, Cameroon and Nigeria Other neighbouring countries however, such as Benin, Togo Sudan and Central African Republic, due to their proximity, and to the fact that they increasingly share the same problems, are often included when the Sahel is discussed.
