Abstract

This study is aimed at identifying suitable sites for developing a municipal solid waste (MSW) landfill that is environmentally and socio-economically friendly for Gombe metropolis. In this study, suitable landfill sites were selected using Geographic Information Systems (GIS), Remote Sensing, Multi-Criteria Decision Analysis (MCDA), and Analytical Hierarchy Process (AHP) techniques. For optimal site selection, seventeen different criteria were identified and their themes derived from landsat-8 of 2015, SRTM of 2000, topographic, geology, hydrology, and soil maps, and point coordinates from fieldwork. Each criterion was weighted using the pairwise comparison method, and the MCDA reveals that only four out of the twenty-seven sites that belong to the very high suitable class are greater than the 10ha required. A site (Site 3) was further selected as the most suitable and cost-effective landfill site in the study area due to its size (193.85 ha), proximity to Gombe (6.7 km from the waste generation center), accessibility (0.7 km from the main road), and convenient morphology (with a slope of less than 6°). The results showed that there is considerable land for landfill development within the study area. Finally, it is recommended that the selected landfill sites be incorporated into the existing master and regional development plans for Gombe metropolis and its surroundings
