GPM used to empower the DAFNE Project Ethiopia’s hydropower development upstream from Lake Turkana altered the natural flow and sediment regime of the Omo-Turkana basin, thus leading to changes in the temporal and spatial water availability in the Lower Omo Valley and Lake Turkana, the inflow of which largely depends on the Omo River. The DAFNE project, an EU-funded project which explores the water-energy-food Nexus in complex transboundary water resource systems of fast developing countries, is identifying sustainable solutions analyzing the trade-offs among the key water uses for hydropower, irrigation and the environment around Lake Turkana. To support this effort, GPM monthly and annual GPM precipitation maps are used to assess the region’s water budget. Tom Ballatore, director and founder of the Lake Basin Action Network (LBAN), develops precipitation maps not only for the DAFNE Project, but produces multiple precipitation maps for several organizations and research projects for lake basin management activities. He also teaches how to access GPM and apply the data for water and agriculture applications across Africa. The DAFNE Project is just one example of many of Ballatore’s works being used for decision-making for Lake Turkana 2017 monthly (left) and annual (right) precipitation using GPM IMERG Final. Maps were water resource issues. used for the DAFNE General Assembly in October 2018. Credit: Tom Ballatore, LABN, http: //www. lakebasin. org/.
