Assessment of solid waste management systems in Ibadan North, Oyo State using geo-spatial techniques

Abstract

Solid waste management has been part of human activities right from time. Effort by the Oyo State Government in managing the collection and disposal of waste generated in Ibadan is seen in the provision of Skip bins at specific locations across the city. However, despite the provisions made by the government, an emerging trend is the dumping of refuse along the median of some major and collector roads in the city. This study aims at emphasizing a planning framework for the location of solid waste disposal infrastructure (Skip bins) through the adoption of planning standard. The aim of this study was achieved by identifying the existing skip bins within Ibadan North. More so, a spatial analysis of skip bins and resident's access to solid waste facilities within Ibadan North was deduced. Geospatial techniques were used for this study; data from primary and secondary source were also used to corroborate the geospatial findings. The study identified a total of 37 skip bins located within Ibadan North Local Government, serving the entire Ibadan North. Spatial analysis of the skip bins revealed a clustered distribution which is consequential to indiscriminate solid waste disposal within Ibadan North.   The study recommends adequate provision and location of skip bins to contribute to a cleaner and safer environment and a design blue print for Ibadan North was proposed.Keywords: GIS, Median, Nearest Neighbour Analysis (NNA), Skip Bins
