The Sahel
The Sahel is a transition zone in Africa between the Sahara Desert to the north and tropical forests to the south. This dryland belt stretches across Africa and is under stress from land use and climate variability.
In the area pictured above, thick bush once stood. Now only scattered Acacia are found. Persistent, unchecked land damage claims both soil and vegetation, leaving little habitat for the region's wildlife. Ultimately, there will be no resources here for people.
These changes are visible on the ground and
from space.
