Suitability location of solid waste collection points for Chanchaga Local Government Area, Niger State

Abstract

Population growth and uncontrolled urbanization has made solid waste management an imperative issue for environmental management and sustainability. The study conducted site suitability analysis for solid waste disposal in each wards of Chanchaga Local Government Area (LGA) of Niger State with a view to recommending most suitable sites for solid waste collection in the study area. The data used for the study was Landsat 8 OLI of 30m spatial resolution, soil map was obtained from Food and Agricultural Organization (FAO), Digital Terrain Model (DTM), Administrative map and the geo-location of the existing solid waste collection points in Chanchaga LGA. The derived factors were reclassified and spatially analysed based on the minimum standard setup by Environmental Protection Agency (EPA), 2006 for high, moderate and least suitable waste collection site. The outcome depicted that about 90% of the solid waste collection site does not meet up with the standard setup by EPA, 2006. Furthermore, the study revealed that most residential buildings were located in a confine radius of less than 50m to most of these collection sites, which is inappropriate and unacceptable. Indiscriminate dumping of waste within residential areas, water body, road network and drainage systems should be discouraged. Provision of waste cans for household and frequent evacuation by the relevant authorities should be encouraged. Finally, based on the EPA 2006 minimum standard, suitable solid waste collection sites were determined and recommended for use in the study area.
