For the suitability analysis of surface irrigation, soil type, slope, land cover, and distance from water supply were considered. The suitability factors data such as soil data was obtained from Ethio-soil, slope was derived from DEM-20 meter resolution, land use/cover was classified from satellite image of 2019 (Landsat 7 ETM+), and distance from the River was obtained from Ethio-River map. For each of the criteria suitability map was developed. Slope was classified as 0-2%, 2-5%, 5-8% and 8-15% as highly suitable, moderately, suitable, marginally suitable and not suitable respectively. LULC was classified by unsupervised classification. For the weighted over lay analysis as the most limiting factor slope was given (40%), land use and River proximity given equal weights (30%). The weighted overlay analysis gave irrigable area of 1.22% highly, 50.87% moderately, 45.77% marginally suitable for surface irrigation but 2.13% is not suitable. Thus, in Humbo woreda small area of the land is highly suitable however; more than half of the area is moderately suitable for surface irrigation. Thus, farmers and the government should invest in those suitable areas for surface irrigation. }, journal={EQA - International Journal of Environmental Quality}, author={Labiso, Tadele Tesfaye and Yagaso, Zewde Sufara}, year={2021}, month={Jan.}, pages={32–43} }
