Portrait of woman, Omo Valley, Ethiopia.
The people of the Omo Valley in Ethiopia have lived their lives virtually undisturbed by outsiders for centuries. What’s more, the region in which they live is even more ancient. The site is on the UNESCO World Heritage List, and according to UNESCO, the area is “unlike any other place on Earth in that so many different types of people have inhabited such a small area of land over many millennia.” There are nine main tribes that occupy the Omo Valley: Arbore, Bena, Daasanech, Dorze, Hamer, Karo, Konso, Mursi and Tsemay.
