Sahel

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. Nonetheless, the region has sustained very high human birthrates, resulting in a rapid increase in population. In recent times, various coups, insurgencies, terrorism and foreign interventions have taken place in many Sahel countries, especially across former Françafrique.

In addition to its ecological and climatic significance, the Sahel is also considered a geopolitical space, shaped by internal instability and external strategic competition.
