Landfill has been proof to be the easiest and cheapest form for the final disposaQl of solid waste management in most developing cities in the world, apart from incineration method of solid organic waste that are subjected to combustion. However, landfill design and siting is an extremely difficult operation due to the fact that the process of identification and selection involves strict rules and regulations. Due to the rapid development and population increase experienced so far in Ile Ife and environs, proper identification and selection of appropriate sites for landfills need to be taken into consideration and systematic procedures need to be adopted and followed? Environmental degradation occurred many years ago, this is result of wrong dumping of municipal solid waste due tonon availability of landfill site. In this study, attempts have been made to determine sites that are appropriate for landfill siting in Ile Ife and environs, by using geo-spatial technique and such geo-spatial data like land use, drainage, road were obtained from the high resolution geo-eye satellite image. All the data obtained were geo-referenced and digitized through on screen digitizing of the entire road, drainage in the study area, using GIS software (ArcGIS) to process the data, to know the slope, aspects, 500m distance of the road to the proposed landfill selected to be appropriate. Suitability of the land was determined from less suitable to the most suitable areas. The final result produced shows the best areas to be the suitable landfill from the map.
