The definition of the area covered

The definition of the area covered varies widely from one author to another. For some, the Sahel includes all the territories bordering the Sahara: there is therefore a northern Sahel and a southern Sahel. However, it is the latter that is designated when no qualifier is added. The sub-Saharan Sahel is divided into five parts: the Mauritanian Sahel, the Malian Sahel, the Niger Sahel, the Chad Sahel and the Sudan Sahel. สล็อต เว็บตรง
