The global implication of desertification:

What is desertification?
Desertification is a form of land degradation where productive and fertile land alters into arid landscapes, incapable of supporting biodiversity. This can occur through natural land ‘evolution’ or human activity increasingly impacting the climate and natural habitats. Farming cattle can often cause deforestation and overgrazing, two prominent contributors to desertification. Other practices/operations like large pesticide and herbicide application, urbanisation, natural disasters, tillage and excessive use of groundwater are all leading causes of desertification globally.
