The term “Sahel” is often applied to the general region extending some 5,000 km across the east-west extent of Africa and from the desert to the humid savanna woodland at roughly 10 o N. “Sahel” more properly applies to a smaller region between the latitudes of roughly 14 o N and 18 o N (Figure 1). It includes much of the countries of ...
