Assessment of Surface Irrigation Potential Using Geospatial Technology in the Megecha River Catchment

The world is suffering from different crises, like the energy crisis, food insecurity, and a basic shortage of natural resources. This study has been conducted to assess the surface irrigation suitability of the Megecha River using geospatial models. The slope gradient, soil depth, soil drainage, soil type, land use (land cover), distance from a water source, and distance of the access road were considered to assess the land's suitability for surface irrigation. After preparing each criteria map, the weight for each parameter was calculated using the analytic hierarchy process and weight overlay map analysis conducted in the GIS environment. After conducting a pair-wise comparison matrix and normalizing the pair-wise comparison matrix, slope gradient, soil type, and soil depth were weighted at 33%, 23%, and 17%, respectively. The land use and land cover change detection revealed that agriculture and built-up areas had shown significant expansion while range land was promptly decreased. The reasons for these are mainly population growth, soil fertility loss, small industries, and business company expansion. About 581.74 km2 of area is moderately suitable, but the Megecha River has the potential to irrigate only 200ha for those selected crops based on CROPWAT 8.0 analysis. Finally, I recommend that the concerned offices enhance the soil and water conservation practices in the Megecha river watershed since it is the main water source for the private sector and the local community and its land use is changing in a hydrologically negative way.
