This study aims at developing a decision support tool for solid waste management in Chanchaga Local Government Area of Niger State using Geo-information Technology. Waste management is a global environment issue, which constitutes a very significant problem in today's world. There is a considerable amount of waste disposal without proper segregation, which is leading to both economic and environmental problems. There is tremendous amount of loss in terms of environmental degradation and health hazards, due to direct disposal of waste. There has to be appropriate planning for good waste management by assessing the waste situation of the area. The method employed was to acquire attribute and spatial information using handheld Global Positioning System receiver (GPS) and satellite imagery. The image was geo-referenced and digitized showing the location of existing waste disposal unit and the final dumpsite. A database was created using ArcGIS 9.3 software. Queries and analysis of results were carried out. The results show primary, secondary disposal units and the condition of the disposal units.
