The Azawagh (alias Azaouagh or Azawak) is a dry basin covering what is today the northwestern Niger, as well as parts of northeastern Mali and southern Algeria.
[1] The Azawagh is mainly made up of Sahelian and Saharan flatlands and has a population that is predominantly Tuareg, with some Arabic-speaking and Wodaabe minorities and a recent influx of Hausa and Zarma.
[4] The bedrock of the region is Cretaceous/Paleocene limestone and clay, which was cut by erosion and covered by aeolian sand in the Upper Pleistocene.
[5] In ecological terms, the Azawagh basin is divided into, from north to south, a Saharian, a Sahelian and a northern Sudanese (referring to the geographic region) zone.
[4] In Niger, Azawagh generally includes the towns of Abalagh (Abalak), In Tibaraden (Tchin-Tabaraden), Tiliya, In Gal and Tabalaq, a village where the sole lake of the region is located.
