Detailed explanation-1: -Desertification in the Sahel can largely be attributed to greatly increased numbers of humans and their grazing cattle.

Detailed explanation-2: -Without the roots of trees and other vegetation, the dust is blown away by the wind. As a result of these issues, water has become scarce for people, animals, and plants of the region. Without water and productive land, farmers and herders are unable to sustain their traditional livelihoods.

Detailed explanation-3: -Many countries around the world suffer from the problems caused by desertification but it is the Sahel region of Africa where the effects are greatest. The Sahel is a narrow belt of land which lies immediately to the south of the Sahara Desert and which extends across most of Africa.

Detailed explanation-4: -Human activities that contribute to desertification include the expansion and intensive use of agricultural lands, poor irrigation practices, deforestation, and overgrazing. These unsustainable land uses place enormous pressure on the land by altering its soil chemistry and hydrology.
