Drought is no rain on moments we expect it. The real problem is not the rain, or lack of it, but the expectation of rain people have.
In the past people moved their herds of animals to places where there was enough to eat. Drought caused the movement of people and animals from one location to another. Drought in the Sahara has led to depopulation of that area, except for some nomads. Underneath the Sahara are huge oil reserves, that point to the fact that there was a sea at some time in history. In the past there was room to move away from the problem. Today countries have borders and if you move, you create a constraint with the people already living in that area. War of survival is looming.
