Afar Goat Herders, Ethiopia, 2005Photograph by Carsten PeterAfar goat herders use a reed mat to shield their campfire from the steady winds of the Ethiopian Danakil Desert. The Afar are a nomadic people who drive their camels, donkeys, and goats in search of the region's scant pasturelands. Centuries of defending their territory and their herds has made them fierce. One Afar custom, now defunct, declared a man could not marry without first killing an enemy tribesman.
