The Sahel 2

Swallowing all but the tallest trees, dunes have buried cropland near the city of Goudoumaria, where a herder follows goats in search of forage. Reduced rainfall has withered vegetation and dried up wells in parts of southern Niger, forcing villagers to move. The Sahel experienced droughts in the 1970s and '80s, and although rainfall has increased since the 1990s, a decades-long dry spell continues.
