Abstract
Determining the location of facility sites in an area with partial planning and a highly growing city is challenging for decision-making. It is even more difficult when assessing suitable site selection for solid wastes. This study used geospatial data to assess suitable landfill site locations to create a neat city using geospatial data for Boditi city, southern Ethiopia. Geographic information systems (GIS) and a multicriteria approach were used with a number of other criteria to help select possible locations. Biased comparisons and weighted scoring methods were used to evaluate the ten criteria used by the city to determine which site was suitable. The locations are sorted into four groups, stretching from highly suitable to unsuitable, using suitability mapping. Overall, of the 3,040 ha, 138.7 ha (4.56%) was considered highly suitable, while 2414 ha(79.41%) was considered moderatelysuitable for landfill sites. In addition, 476.21 ha (15.66%) was identified as less suitable, leaving the remaining 11.09 ha (0.37%) considered unsuitable. The study selected the best landfill site in terms of accessibility, topography, and compensation cost in addition to ten criteria that will help minimize the risk of adverse impacts on life, land, water, and air environments associated with waste disposal.
