Damming the Omo River has led to the development of many large-scale commercial irrigation schemes within the Lower Omo Valley. These developments will make the Lower Omo, the largest irrigation complex in Ethiopia and has ultimately led to forced resettlement of the agro-pastoral population of the lower Omo region.
These new developments have also led to the construction of many new roads and telecommunication networks which has ultimately made this remote region more accessible to the outside world. Globalisation is making its mark on The Omo Valley and it is greatly affecting the traditional communities who have inhabited this region for well over a millennium. The Kara, Dassanech, Abore, Hamar, and Mursi people are the tribes that have been affected most. None of them have given their free, prior and informed consent for the dam or the plantations and many of their communities have already started to lose their livelihoods.
