Ibrahima Fall collects limes from his orchard in the village of Ndiawagne Fall in Kebemer, Senegal, on Friday, November 5, 2021. The citrus crop provides a haven from the heat and sand that surround it. Outside the low village walls, winds whip sand into the air, inviting desertification, a process that wrings the life out of fertile soil and changes it into desert, often because of drought or deforestation.
