How have human activities caused desertification? Explain.
Desertification caused by human activities. The development of the fertile topsoil takes centuries. But it can be removed very easily due to human activities. Over-cultivation Unrestricted grazing Deforestation Poor irrigation practices. All these human activities result in arid patches on land. When large barren patches extend and meet over time a desert is created. Thus desertification is a major problem particularly due to increased urbanization.
