The increasing world population, coupled with the growing pressure on the land resources, necessitates the application of technologies such as GIS to help in identifying the most suitable areas for a sustainable agricultural production for food supply according to the environmental potential. Selecting the best location for agricultural production is a complex process involving not only technical requirement, but also physical, economic, social, and environmental requirements that may result in conflicting objectives. Such complexities necessitate the simultaneous use of several decision support tools such as Geographic Information Systems (GIS) and Multi Criteria Decision Analysis (MCDA) using analytical hierarchy process (AHP). In this paper a model was developed to determine the suitability of the area for agricultural production using soils, slope, water bodies and geological maps of the area to support decisions making for sustainable agricultural production. This integration could benefit farmers and decision makers in agriculture planning. The central theme of this paper is to explain the process of developing a prototype GIS application to provide a system for supporting location decisions with respect to the implementation of agricultural planning. GIS was used based on a set of criteria derived from the spatial and environment aspect.
