When the dam started to be built in 2006, global human rights organizations and indigenous groups complained of the effects the dam would have on the natural flood cycle of the river, which was crucial to traditional livestock grazing and flood-retreat farming. Global financiers and Ethiopian authorities were protested against and appealed to by claiming the dam will lead to forced displacement, hunger, and loss of tradition. Despite there being a mass outcry and environmental warnings, the Ethiopian government proceeded, oftentimes muzzling opposition and marginalizing Indigenous voices during consultations. In 2010, a resurgence of protestors came to fight for their land outside of the construction site of the Gibe III Dam, and were ultimately given further compensation and moving accommodations after the Dam had finished construction. However, by the time it was opened in 2016, its effects like land degradation and low water flow to Kenya's Lake Turkana had already begun to affect the most vulnerable in the region. It was decided the compensation was not enough to justify the ecological damage the dam had caused.
