The eastern region of Ethiopia, the Afar, is an area of surreal, almost lunar, and is among the hottest places in the world with an annual average of 34.4° C. It is located a few kilometers from the border with Eritrea, in an area of volcanoes, geysers and hot springs characterized by yellow-orange colors and gigantic salt deposits. In this inhospitable environment lives the Afar people, nomadic shepherds who, right from salt extraction, are a precious resource for their subsistence.
