An explanation of how changing rainfall patterns together with increasingly intensive land use have combined to contribute to desertification in the Sahel region of Africa. It shows the location of the Sahara Desert and the Sahel region within Africa and looks at the changing patterns of rainfall in the last 50 years or so. It goes on to show how the need for fuelwood and cattle grazing has led to the spread of the desert. It finishes with images of before-and-after scenarios and an animation of the southward spread of the desert.
