Low water use efficiency is a challenge to crop production in Sub-Sahara African countries. Water is getting continuously scarce due to increased demand and shrinking availability induced mainly by climate change.
In Ethiopia, soil erosion during the rainy season constitutes a sever threat to the national economy. The study site, head of the Abay basin is among the heavily affected areas, which is a peril for the crop water productivity.
This study conducted in two sub catchments of the Abay Basin identified the quantity and quality of sediment loss and its origin though most studies conducted in Ethiopia focus on quantification of soil loss.
