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.

Pupils could watch the clip without sound and try to work out the causes and effects of desertification just from looking at the images. Debrief the class and then play the clip with narration to fill the gaps. Or, students could watch the clip with narration and then be given the task of writing the script. Sketches will be useful to explain the process of desertification.
