what is desertification?
Desertification is a type of land degradation where a relatively
dry area of land becomes increasingly arid. In Africa, it can be caused
by overgrazing, which is when a herd of animals graze
so heavily that the vegetation is damaged and the ground becomes
vulnerable to erosion.
