摘要

Urbanization and population growth are closely linked to high solid waste discharge, making solid waste management difficult in Ethiopia's megacities and developing cities. This calls for selecting appropriate waste disposal sites while considering socio-spatial and environmental factors. Therefore, the primary goal of this research is to identify a potential location for the disposal of solid waste by utilizing integrated geospatial technologies (GIS-based MCE methods and GPS). While socioeconomic data was used to evaluate the environmental effects of the current and existing solid waste disposal sites (SWDS), geospatial parameters such as elevation, slope gradient, LULC, lineaments, road network, surface water, groundwater level, and well points were used to develop new SWDS. The study's findings demonstrate how present trash disposal procedures and disposal locations lead to environmental and societal issues. This is because there is no socioeconomic or environmental parameter categorization, and the disposal sites already in place are situated randomly. GIS-based MCE results show that 19.96% of the research area is unsuitable for municipal solid waste disposal. The remaining 20.75% and 20.63% are categorized as less and moderately suitable classes, respectively. On the other hand, 18.32% of the study region is a highly appropriate location for SWDS, while 20.34% of the study area indicated a suitable class. In summary, this study recommends that the current SWDS be reevaluated and moved to incorporate the suggested locations appropriate for the town's development sustainability.
