Desertification, Coupification

The Sahel is the name of the belt of arid land south of the Sahara desert proper. It's also the portion of the continent that's been referred to as the "coup belt", due to the fact that in the last three years, countries from Guinea in the west to Sudan in the east have been rocked by coups d'etat. 

As north Africa dries out, the Sahel has been spreading southward. So, apparently, is the coup belt.
