Africa has been experiencing increasing drought since the time the forests disappeared and man's ancestors had to learn to live on the Savannah.
>Africa will experience increasing drought as global warming progresses in the coming decades.<
It doesn't help that people cut every tree, such as they are, for firewood, so the land never has a chance to recover. In addition, look at what's happened in Zimbabwe. All it's taken is a few years without decent farming practices to plunge the breadbasket of Africa into the cycle of famine.
This is not the fault of other countries, the Africans need to look in the mirror, and quit pointing fingers at the rest of the world.
