SS7G2The student will discuss

environmental issues across the continent of Africa.

b. Explain the relationship between poor soil and deforestation in

Sub-Saharan Africa.

The Sahel is an area of Africa south of the Sahara Desert. It’s an example of how poor

farming practices and the destruction of trees and shrubs can lead to an expanding

desert.

Above: The wind easily erodes the soil because there is little vegetation. The landscape is brown and desolate for most of the year. Loose sand even moves onto the

road.

Most historians believe that the Sahel was once rich farmland. Centuries of farming and grazing along with less rainfall have gradually damaged land in the Sahel.

Millions of people struggle to farm in its poor soil.

Deforestation is the destruction of trees and other vegetation. This continues to be a problem in the Sahel and elsewhere in

Africa.

Animals have been allowed to graze too heavily in an area and have stripped all of the vegetation from the soil. People who

need fuel or who hope to clear new farmland have cut

down the trees that help hold the soil in place.

purposes

Droughts, or long periods of time with little rainfall, have hurt the Sahel, too. The people who live in these areas often face starvation and poverty. Many move into

urban areas hoping to find work, but most find only poverty.

In recent years, the United Nations and the World Food Bank have come to the aid of

those living in parts of the Sahel. They have worked hard to find solutions to help people

survive and live a better life. Below: Some 3.6 million people in Somalia depend on

humanitarian assistance.
