There are immeasurable crooks and nannies to this solution, one of them that many of the current nomadic tribes historically used to call the shots and now are pushed more and more into an outcast position. Divides between tribes and clans are far from buried. Politicians (generally non-nomadic) abuse the nomadic tribes in their turn and there is a growing disconnect between the city-politicians and the tribes.

Actually, politics in Africa can be so depressing, I have my first hopes on commercial nature-reserves, which would abuse the "novelty" of nomadic tribes for a part, but would (hopefully) allow the majority of the tribe alone to their own lifestyle.
