Water balance components of the potential agricultural grabens along the Rift Valley in northern Ethiopia

Ethiopia’s Rift Valley. matching agricultural water demand and supply is a growing policy challenge in drylands. We investigated the water balance components in Raya (3507 km2) and Ashenge (80.5 km2) grabens. The rainfall depth, river discharge, abstraction, climate and soil data (2015–2017) were used to address the research question. New hydrological insights: the average annual rainfall of the graben’s escarpment and its bottom was 806 ± 162...
