The Omo-Turkana Research Network (OTuRN) is an international consortium of social and environmental scientists researching the impacts of hydrological, agricultural, and social change on the people and ecosystems surrounding the Lower Omo Valley and Lake Turkana – i.e. the Turkana Basin. The objectives of OTuRN are to facilitate communication among researchers active in the basin, to coordinate multi-disciplinary research, and to assist in disseminating knowledge to the media and to members of the public.
The Turkana Basin covers approximately 131,000 km^2 in southern Ethiopia and northern Kenya. Hydrologically closed, the basin is dominated by Lake Turkana, with the Omo River on the Ethiopian side supplying 90% of the input to the lake. Other major inputs include the Turkwell and Kerio Rivers on the Kenyan side. Lake Turkana is the world's largest permanent desert lake and the world's largest alkaline lake. The Basin is home to approximately 500,000 people, belonging to multiple indigenous groups, and practising diverse livelihood strategies including pastoralism, agro-pastoralism, and fishing.
