Multi-criteria irrigation land suitability analysis and mapping can play an important role notrnonly in sustainable use of scarce resource, but also in overcoming the global problem ofrnwater scarcity and crop production caused due to high degree of rainfall variability andrnunreliability. The General objective of this work was to Map suitable land for Surfacernirrigation potential using GIS and remote sensing based multi criteria analysis in the abbayrnbasin, upper Blue Nile, Ethiopia. The study employed Geographical information Systembasedrnrnmulti criteria land suitability analysis method considering eight factors, namely, soilrnpH, soil drainage, soil depth, Cation Exchange capacity of the soil, texture classes, Runoff,rnslope, and distance from the main river to find suitable land for surface irrigation. Using thernWeighted Overlay tool, the values of each dataset were weighted and combined to find thernmost suitable location for irrigation using the ArcGIS environment. The results of the studyrnrevealed that about 5741870.55 ha (29.26 % of the watershed area) highly suitable,rn7013480.98 ha (35.74 % of the watershed area) moderately suitable, 5013834.33 ha (25.55 %rnof the watershed area) marginally suitable, 1854431.87 ha (9.45 % of the watershed area) notrnsuitable. The findings drawn from this study can play an indispensable role in boostingrnirrigable land in the study area by considering suitable irrigable lands in terms of the eightrnfactors described. About 38892.70ha of land can be irrigated at the gauge location of thernrivers in South Gojam watersheds without further development on the downstream.
