Geospatial Distribution Of Waste Dumpsites And Socioeconomic Factors Influencing Waste Management Practices In Abeokuta South, Nigeria.

Abstract

Rapid urbanisation has continually led to waste increase, placing a demand on dynamic waste management for effectiveness. This research focuses on the examination of the potential geospatial distribution of waste dumpsites and the socioeconomic impacts on managing waste in Abeokuta South, Nigeria. Fourteen (14) dumpsites were observed and mapped using geospatial techniques, with buffer zones of 100m, 500m, and 1km indicators monitoring significant residents vulnerable to the hazards relating to dumpsite. Households falling within the exposure buffer zone are then visualize. Additionally, structured questionnaires were administered to residents within these distances to evaluate the influence of socioeconomic factors—particularly income and education levels—on waste disposal methods, including open burning, open dumping, incineration, and waste collection. Results revealed that many households in Abeokuta South reside within 100m proximity to a dumpsite, a proximity linked to increased respiratory health risks. Furthermore, the study shows that lower-income and less-educated households were more likely to engage in open dumping and burning. Among these respondents, 68% and 46% who practiced open dumping and open burning, respectively, were low-income earners. However, keeping waste for collection was the most widely practiced disposal method across all income groups. 44% of low-income, 50% of middle-income, and 6% of high-income households adopted this practice. These findings reveal that while household income levels significantly influence waste management behaviors, the strategic placement of waste bins can help mitigate improper disposal practices across different income groups.
