Awash River basin is one of the major 12 river basins in the country and it is the fourth populous basin in Ethiopia and ranks the 3rd of all basins of Ethiopia in terms of population density and stands 4th and 7th in its area and volume of water respectively. The relative surface water resource of the basin is about 4.65 billion m3, it is the most developed and utilized since 77.4% of the irrigable land in the basin has been cultivated. About 60% of the large-scale irrigated agriculture and more than 65% of the national industries are located in the basin. This Current Topic aims to review literatures information related to irrigation potential of Awash River, status, challenges and opportunities irrigation practices in Awash River Basin.
