Children herd cattle in the Sahelian region of northern Senegal. Using satellite data and statistical modeling, South Dakota State University scientists confirmed that the semiarid Sahel region, which is dependent on seasonal rains, have largely recovered from devastating drought in the 1970s and 1980s.
