What is desertification? How are nomads and droughts related to this process? (Site 2)

Answer 1

Desertification is the process by which fertile land becomes a desert, typically as a result of drought, deforestation, or inappropriate agriculture. Nomads and droughts are related to this process because nomadic herders often rely on grazing their livestock on semi-arid land, and prolonged droughts can cause vegetation to die and soil to become infertile, leading to land degradation and ultimately desertification. Additionally, nomads may overexploit resources in an area, contributing to soil erosion and further land degradation. Climate change, which can lead to more frequent and severe droughts, is also exacerbating the problem of desertification in many regions.
