The study produced numerous map outputs, including physical resources maps
(landform, soil, climate, land resources), potential crop suitability maps, as well as maps of potential population supporting capacities and maps of optimal land resources allocations by district and for the whole of the country. Figure 2 shows a map of suitability for rainfed production of cowpea at the intermediate level of inputs. Potential crop suitability is assessed by matching the land (soil, landform and climate) attributes described in the land resources inventory with the requirements of the crop expressed in terms of the land attributes
