The human activities like over-cultivation, unrestricted grazing, poor irrigation practices, results in arid patches of land (deforestation). When these large barren patches extend and remain unattended for long, a desert is created. Because the formation of fertile top layer of soil takes millions of years, desertification easily takes over.
