Rainwater management for resilient livelihoods
                                                 Integrated Rainwater Management Strategies:
                                                            Hydrometric Monitoring
                                                     Mizewa Watershed in Fogera Woreda

                                                 Description
                 Located in the north-east of the Abbay basin,
                 to the east of Lake Tana

                 Tributary to Ribb river

                Rainfall: 1,000 – 1,500 mm
                                                                                                                                  Area
                                                                                                                                27.0 km 2
                 Large flat floodplain in the vicinity of the lake
                 and hilly catchments to the east

                Traditional diversions and increasingly small
                pumps used for irrigation
                                                                                                              Interventions
                                                                                             18 trapezoidal RWH ponds (129m3) lined with
                                                                                             geo-membranes have been constructed

                                                                                              Soil conservation practices: terracing, zai pits,
                                                                                              hydro-basins afforestation & protected areas

                                                                                              67 new RWH to be constructed by Ag. Bureau
           Rice cultivation                                Trapezoidal pond



                                                 Challenges
                 Flooding and water logging

                 Drying-up of streams in the dry season and
                 hence water scarcity

                 Conflicts between upstream and downstream
                 water users                                                             Water logging of Maize

                 Constructed rain water harvesting ponds                                                              Proposed location for flow
                 failing for a variety of reasons                                                                     monitoring
