The Sahel region (/səˈhɛl/; from Arabic ساحل (sāḥil [ˈsaːħil]) 'coast, shore'), or Sahelian acacia savanna, is a biogeographical region in Africa. It is the transition zone between the more humid Sudanian savannas to its south and the drier Sahara to the north. The Sahel has a hot semi-arid climate and stretches across the southernmost latitudes of North Africa between the Atlantic Ocean and the Red Sea. Although geographically located in the tropics, the Sahel does not have a tropical climate.

Especially in the western Sahel, there are frequent shortages of food and water due to its very high government corruption and the semi-arid climate. This is exacerbated by very high birthrates across the region, resulting in a rapid increase in population. In recent times,[when?] various coups, insurgencies, terrorism[1] and foreign interventions have taken place in many Sahel countries, especially across former Françafrique.
