Hydro-meteorological response to climate change impact in Ethiopia: a review

Abstract

Climate change poses significant challenges to water resources and streamflow in Ethiopia, a country highly dependent on agriculture and vulnerable to environmental shifts. This paper reviews the current state of knowledge on climate change impacts on streamflow in Ethiopia, emphasizing factors driving these changes and drawing insights from relevant studies. The analysis encompasses hydrological responses to climate change, including alterations in precipitation patterns, temperature fluctuations, and changes in water availability. Additionally, the study examines the impact of land use changes on streamflow dynamics. Comparative insights from neighboring countries and river basins further illuminate the broader regional implications of climate change on water resources. According to the previous research reviewed in this paper, climate change, land use change, and increment in extreme events (drought) have affected the stream flow over the last decades. The findings underscore the urgent need for adaptive strategies and sustainable water management practices to mitigate the adverse effects of climate change on streamflow and ensure water security in Ethiopia and beyond. HIGHLIGHTS The review paper provides localized insights into climate change impacts.; It contributes valuable information for water resource managers and policymakers.; It assesses the risks posed by climate change to Ethiopia's hydro-meteorological conditions.; It explores the socioeconomic consequences of hydro-meteorological changes induced by climate change.; The review contributes to the scientific knowledge base.;
