Abstract

There exist a large outcry over increasing and indiscriminate dumping of refuse in Yewa South Local Government Area of Ogun State, South West Nigeria. This is as a result of the increasing population which has brought about massive volume of waste being generated every day in the area. Unfortunately the management of these wastes is deteriorating day by day due to the limited resources in handling the increasing rate of generated waste. This work developed a GIS based model with the restriction and factor criteria using Arc toolbox and then employing the GIS based Multi-Criteria Decision Analysis (MCDA) such as Analytical Hierarchical Process (AHP) for selecting a suitable landfill site in Yewa South LGA. Suitability map was created after Restriction and factor maps were produced using ArcGIS analytical tools and possible sites that are suitable for sitting landfills were finally identified. Study showed that the area is characterized mostly by Shrubs, Cultivated lands and Built up areas. The shrub lands are presumed to suitable for siting Landfill but some factors (natural and artificial) needed to be considered in these shrub lands before concluding its suitability for Landfill. Result has shown the effectiveness of GIS’s Analytical Hierarchical Process (AHP) for selecting a suitable landfill site in the area even in the next 100years. Despite the availability of highly suitable areas, the application of GIS tools using predefined parameters made the most probable site selection yet a reality. The result of the suitability map could be clearly understood, it can assist in getting full support especially from the public as the selected site is not located on, or near, any environmental interest areas and it is also located at significant distance away from streams, roads and residential areas, which minimizes social conflict and environmental impacts.
