Detailed explanation-1: -But since the late 1960s, the Sahel has endured an extensive and severe drought. Desertification occurs when land surfaces are transformed by human activities, including overgrazing, deforestation, surface land mining, and poor irrigation techniques, during a natural time of drought.
Detailed explanation-2: -Bordering the Sahara Desert and the Savannas, the Sahel region in Africa has been affected by devastating droughts over the last number of years. It has become a desert, making it more difficult to inhabit and produce anything on the land. For around 8 months of the year, the weather is dry.
Detailed explanation-3: -Collectively owned land led to deforestation as well as overgrazing. Forests were depleted as individuals collected wood for burning. Trees and ground cover are necessary to help maintain the soil in the farm lands. Without them, the soil breaks down, gradually turning the area into barren wastelands.
Detailed explanation-4: -Human activities that contribute to desertification include the expansion and intensive use of agricultural lands, poor irrigation practices, deforestation, and overgrazing.
