​Today, Africa's Sahara desert is expanding south into the Sahel region primarily as a result of desertification caused by ____.

Quizplus · Accepted Answer

Overgrazing by livestock is the primary cause of desertification in the Sahel region, which is leading to the expansion of the Sahara desert. Livestock and their overgrazing are stripping the land of vegetation and making it more vulnerable to erosion, drought and other environmental pressures. This is resulting in the gradual drying up of the region, transforming it from a semiarid grassland into a desert.
