DROUGHT



                    AND FAMINE




                     SAHEL DROUGHT






                  Many tropical countries have alternating dry and
                  rainy seasons, so people rely on crops that they can
                  grow in the months when it rains. But sometimes
                  the rain does not fall, the land turns to dust, and the
                  crops fail. The worst of these droughts have occurred
                  in the Sahel region on the southern fringes of the
                  Sahara Desert in Africa. Some droughts have lasted many
                  years, and as water supplies dry up and crops wither
                  in the fields, farm animals die and the people starve.
                  Such famines may occur more frequently, as climate
                  change makes the seasonal rains even less dependable.
