| dc.description.abstract | Multi-criteria geospatial modelling using Geographic Information System and remote sensing data were carried out with the objective of identifying suitable waste disposal sites that are both economically feasible and environmentally sustainable in Owerri Metropolis and environs, Imo State, Nigeria. Several data sets including climatic data, soil, groundwater, drainage, landuse/land cover and slope data were extracted from satellite data were used to generate several thematic maps which will aid the siting of eco-friendly landfills in the study area. Two vintages of Landsat -8 data for years 2000 and 2020 were used to investigate the spatiotemporal dynamics of the landuse characteristics of the study area. Data collected were geocoded and geo-referenced using the handheld GPS instrument. The GPS coordinates of individual waste containers/dump locations were also obtained. The acquired data sets were further processed using a set of software which include ESRI ArcGIS 10.8, ENVI 5.2, and Geomatica. Various investigations were carried out using the ArcGIS 10.8 software to evaluate the potentials of GIS in the robust management of solid waste in the study area. The study produced several thematic maps which include topographical map, watershed/drainage map, lineament/lineament density map, colour composite maps for, normalized difference vegetation index (NDVI), normalized difference built-up index (NDBI), normalized difference water index (NDWI), and Land use/Land cover Maps for 2000 and 2020 respectively. Weights and factor parameters were determined using the analytical hierarchy process pair-wise comparison model. In addition, map overlay analyses were used to create the land fill suitability map of the study area which was classified into low, medium and high suitability based on the multi-criteria data used. The GIS examination of the trademark elements of the site area yielded field (5) appropriate points. They identified landfill locations are believed to be robust to limit ecological and human risks of the dumpsites. Field inspection and ground truthing of the selected five points further confirmed the suitability of the selected locations. This strategy has therefore been shown to be effective for waste management and landfill site selection. | |
