The Sahel is the strip of land that separates savanna from the desert. Sahel comes from the Arabic word for "edge" or "border" because it is the edge of the desert. The Sahel is shrinking at an alarming rate. Animals have been allowed to graze on its fragile land, which has destroyed the vegetation. The people who live along the Sahel have caused it to shrink by cutting trees and bushes for fuel. Without the trees and bushes to hold it in place, the thin topsoil is of the Sahel blown away, leaving stony land where neither grass nor crops can grow. The Sahara and the Kalahari Desert creep one hundred miles closer to one another every year as desertification and erosion spread.
