The application of any formal economic analysis is, of course, seldom possible in the earlier stages of a land . Land suitability assessment for irrigation is a very important tool not only in terms of agriculture development planning, but also to overcome the global problem of water scarcity. The area of planned irrigation schemes under each land suitability category is also provided. The weighting analysis of all parameters resulted that 34.08% was classified as high suitable (S1), 58.08% moderately suitable (S2), 3.8% marginally suitable (S3), whereas 3.21% not suitable (N) for surface irrigation development. There is no necessity for subsurface drainage. The NIIB may be calculated as follows: Minus (B) Annual Equivalent Value of Common Costs; Minus (C) Annual Equivalent Value of Area-specific Land Development Costs. 3.1 General. Some of the feasible solutions such as intensification of cultivation with double cropping in suitable environment, proper nutrients, water, pest and post-harvest management practices must be pursued on war footings. The critical objective of this study was to evaluate the suitable land resource potential for irrigation development for the Katar River watershed in the Rift Valley Basin in Ethiopia by using ArcGIS . The latter are area-specific costs and are land class-determining. Establishing the cut-off between suitable and not suitable land Using a geographic information system, the researchers determined the physical irrigation suitability of the Sibilu River watershed. The irrigation land suitability factors considered in this study were physical soil properties namely soil depth, soil drainage and soil texture as well as the slope of the land, land use . This land can be farmed under irrigation in the natural condition in spite of the undulating topography. This land use pattern will serve as the basis for locating the project's major water supply and drainage systems, and for calculating irrigation benefits. 7.2 Budgeting Main water supply 8-12-meter (25-40 feet) pressure will delivery a standard two- storey building, although taller buildings will include pressure booster systems. The soil suitability index was combined with the terrain suitability categories to generate the final suitability map. Other similar supporting data could include schedules of the monthly and seasonal pattern of labour requirements, agrochemical usage and costs, etc. The poorest land to be classed as 'Suitable' must be able to carry its share of the common project costs, otherwise it should be classified as 'Not Suitable'. 213.
