Multicriteria spatial model to select landfill sites for solid waste management in Tercha town, Southwest Ethiopia

Year: 2023

Type: article

Abstract: The increase in open dumping and burning of solid waste in Tercha town, Southwest Ethiopia, has become a major environmental and public health concern. This research aims to identify suitable landfill sites for accommodating the increasing amount of solid waste generated as a result of urban expansion in the area. Various criteria such as slope, land use, soil type, distance from settlement, drainage, road, borehole, lithology, and fault were considered to generate a suitability map using the Analytic Hierarchy Process (AHP) procedures. The multi-criteria evaluation methodology was applied to identify suitable sites according to the specified decision rules. The results showed that only 1.9% of the study area was highly suitable for a landfill, while 3% was unsuitable, and 34.91% and 60.1% were moderately and less suitable, respectively. From the highly suitable areas, criteria such as distance from the city center, settlement, and size of the landfill were considered, and Landfill site 4 was identified as the most suitable option. The other candidate sites were ranked lower according to the AHPs. Finally, by considering complex physical and socioeconomic factors, a suitable landfill site has been selected. This research provides valuable guidance to local government officials in establishing proper waste disposal regulations and practices.
