XIV 374A - Arago - Karo Tribe - Korcho Village, Omo Valley - Ethiopia, 2011 The Omo Valley, situated in Africa’s Great Rift Valley, is home to an estimated 200,000 indigenous peoples who have lived there for millennia. Amongst them are 1,000 to 3,000 Karo who dwell on the eastern banks of the Omo river and practise flood-retreat cultivation, growing sorghum, maize and beans. “A close friend can become a close enemy” The Karo were known for their magnificent houses (when still rich in cattle), but after they lost their wealth, they adopted the much lighter conical huts. Every Karo family owns two houses: the Ono, the principal living room of the family, and the Gappa, the centre of several household activities.
