Topoclimate, orographically enhanced rain on windward slopes and leeward rain shadows, control rainfall variability in tropical mountains. Such variability may cause a substantial societal impact in populated highlands such as in Ethiopia. This study aims at understanding the rainfall diurnal cycle and the orographic driving factors over the Ethiopian highlands using the ALARO‐0 regional climate model at convection‐permitting...

Flood‐based farming is a means of improving crop production in rain‐deficit lowlands. Such spate irrigation systems are growing in importance, although the effects of headwater hydrological deficit on downstream flood farming are lacking evidence. This study investigates the impacts of headwater hydrological deficit on the extent of spate‐irrigated agriculture in the Guguf spate system. The length of canals and area of spate‐i...

Irrigated agriculture in the rainfall‐deficit semi‐arid lowlands of the Raya valley rely on spate systems to produce food crops. Climate and land‐cover dynamics upstream are, however, threatening runoff response reaching these spate systems. The objective of this study was thus to analyse the hydrological response of dryland catchments to changing climate and land cover in Guguf spate systems. Thirty‐six years of climate data...
