Dropping water levels in Kenya’s Lake Turkana following the development of dams and plantations in Ethiopia’s lower Omo Valley threaten the livelihoods of half a million indigenous people in Ethiopia and Kenya, Human Rights Watch said today.Based on publicly available data from the United States Department of Agriculture, Lake Turkana’s water levels have dropped by approximately 1.5 meters since January 2015, and further reduction is likely without urgent efforts to mitigate the impact of Ethiopia’s actions. Human Rights Watch research based on satellite imagery shows that the drop is already affecting the shoreline of the lake, which has receded as much as 1.7 kilometers in Ferguson Gulf since November 2014. The Gulf is a critical fish breeding area, and a key fishing ground for the indigenous Turkana people.
“The predicted drop in the lake levels will seriously affect food supplies in the Omo Valley and Lake Turkana, which provide the livelihoods for half a million people in both Kenya and Ethiopia,” said Felix Horne, senior Africa researcher at Human Rights Watch. “The Ethiopian government’s moves to develop its resources should not endanger the survival of indigenous people living downstream.”]
In 2015, the reservoir behind the new Gibe III dam in Ethiopia began filling. Water that previously flowed unimpeded into Lake Turkana, replenishing seasonal drops in lake levels, has since been held behind the Gibe III dam. In 2015 the annual July-November flood from the Omo River into Lake Turkana did not occur, resulting in a drop of water levels of 1.3 meters from November 2014. The very limited artificial release of water from Gibe III in 2016 was not enough to replenish water levels in Lake Turkana. As of January 30, 2017, lake levels were approximately 1.5 meters lower than they were two years earlier according to the data.
People living in fishing communities along Lake Turkana who spoke to Human Rights Watch in August 2016, were generally aware of the risks posed by Gibe III but largely uninformed about the plantations and the devastating impact they could have on their livelihoods. When Human Rights Watch visited communities around Ferguson Gulf on the western lake shores that month, local residents had noticed changes from previous years in the lake levels.
