Climate change alters the spacial and temporal availability of water resources by affecting the hydrologic cycle. The main objective of this paper is to review the climate change effect on the water resources of the Blue Nile River, Ethiopia. The impact of climate change on water resources is highly significant as all natural ecosystems and humans are heavily dependent on water. It alters precipitation, temperature, and streamflow of the Blue Nile river basin which is threatening the lives and livelihoods of people and life-supporting systems. Rainfall within the Blue Nile river basin is highly erratic and seasonal due to it being located in the inter-tropical convergent zone. The temperature and sediment load are shown to increase in the future while the rainfall and streamflow are decreasing. The Blue Nile basin is characterized by highly erosive rainfall, erodible soil, and shrinking forest cover. Therefore, mitigation and adaptation measures should be applied by considering these characteristics of the basin. Watershed management methods like afforestation and water conservation are recommended to reduce the impact on the Blue Nile basin.

气候变化通过影响水文循环而改变了水资源的时空可用性。本文的主要目的是回顾气候变化对埃塞俄比亚青尼罗河水资源的影响。气候变化对水资源的影响非常重要，因为所有自然生态系统和人类都严重依赖水。它改变了青尼罗河河流域的降水，温度和水流，威胁着人们的生命和生计以及维持生命的系统。由于青尼罗河流域位于热带汇聚区，因此其降雨是高度不稳定和季节性的。未来温度和沉积物负荷将增加，而降雨和水流将减少。青尼罗河盆地的特点是降雨侵蚀性强，土壤易蚀且森林覆盖率不断下降。因此，应考虑流域的这些特征采取缓解和适应措施。建议采用绿化和节水等流域管理方法，以减少对青尼罗河盆地的影响。
