Human Causes of Desertification Physical Causes of Desertification Allowing too much livestock to graze on a piece of land which means all the vegetation is eaten making the ground susceptible to wind and water erosion. If you farm land to intensively and don't have fallow periods then all the nutrients in the soil get used. Cutting down trees which not only means the land will be receiving less nutrients, but it also means it is more vulnerable to erosion because there is no and less stability because the root systems have been removed. As the world population Rising As global increase it is becoming hard for to grow thus reducing cover and the risk of wind and water erosion. Falling Rainfall: As the amount of rainfall reduces in some areas like the Sahel, then it is hard for to grow again making the ground more to wind and water erosion. Flash floods: Intense periods of rainfall can also cause erosion of topsoil which leads to
