Detailed explanation-1: -The Sahel Region has lost millions of hectares of easily accessible farming land to the desert, thus creating food insecurity and loss of income for thousands, if not millions, in the region.

Detailed explanation-2: -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-3: -Desertification and deforestation have long threatened the region. Abject poverty has led farmers and herders to cut down forests, overgraze livestock and overcrop land. According to the FAO, more than 80 percent of the Sahel’s land has been degraded.

Detailed explanation-4: -This happens mainly as a result of human activity and hot, dry climates that make it difficult for the land to recover. Both human hands and natural forces can cause and worsen desertification. The Sahel often suffers from naturally occurring periods of drought-long spans of time with little or no rain.
