Abstract Crop suitability analysis using novel models is a pillar for sustainable land-use planning. In this work, the analytical hierarchy process (AHP) was integrated with GIS to produce maps wheat and maize under sprinkler irrigation broad bean drip irrigation. The study conducted in an arid area, west Nile Delta of Egypt. characteristics local climate, landscape, groundwater quality were ma...
