Session Type: Paper


The paper aims at analyzing selected environmental variables in order to develop the suitability map for rice production in Ogun state, Nigeria.GIS multi-creteria Decision Model was used to assess rainfall, temperature, soil and slope conditions and to create the rice suitability map, Analytical Hierarchical Process (AHP) was adopted to rank the selected variables suitable and the resulting weight were used to construct the map layers using weighted sum overlay tool within GIS 10.3.1 platform. Secondary data was also collected from Ogun State Agricultural Development programme in addition to site visit for verification of the mapping outcome. Secondary data was also collected in addition to field to visit site visit to verify the outcome of the suitability map. The result shows that 29.58% of the state is highly suitable, 16.40% was moderately suitable while 19.09% was not suitable. The paper concludes that state government efforts to enhance food security could be driven with much focus on 19.09% of the land area.
