These tribes who have never been part of the formal economy and who prefer to self-govern by their own customs and interpretations of land borders are at risk. A very controversial dam, the Gibe III is being constructed up river from their lands. The Gibe III will be the largest hydroelectric plant in Africa. The social and environmental impacts of the dam are expected to be severe. Many of the tribes depend on the annual flood cycle of the Omo River to sustain their crops. The dam will put an end to the annual flood as well as deplete water levels in the river and in Lake Turkana. On top of that, new, enormous sugar cane plantations are being plotted out on their lands, near the dam's new irrigation channels, which will displace many tribes. As the tribes have no representation, the government will try to force the tribes into resettlement camps and although the government says the plantations will create jobs, it will be a sedantary and restricted lifestyle for a free people so used to living with nature - See more at: http://www.inspirationgreen.com/tribes-of-the-omo-valley.html#sthash.TlDaTWWO.dpuf
