Desertification is a type of land degradation in which a relatively dry land region becomes increasingly arid, typically losing its bodies of water as well as vegetation and wildlife. It is caused by a variety of factors, such as climate change and human activities.
Desertification is largely caused by unsustainable use of scarce resources. What options exist to avoid or reverse desertification and its negative impacts?

Desertification is a process of land-degradation by which a region becomes progressively drier and drier — eventually becoming desert.
Desertification does not occur in linear, easily mappable patterns.
Overgrazing is the major cause of desertification worldwide.
Desertification does not occur in linear, easily mappable patterns. There is no consensus among researchers as to the specific causes, extent, or degree of desertification.
