What causes it?

 What causes Desertification? There is multiple causes of desertification. It is said that wind can blow the sand and stretches the desert boundaries making it larger. Another theory is that cows or other animals grazing the land leaving no grass behind makes the process of desertification quicker.


This would be an example of the cows turning the land into desert.
 Behind them is desert and their fertile land is running out.
