Site selection model for urban solid waste disposal management using GIS and remote sensing: a case of Gulu Municipality
(International Journal of Environment and Waste Management, 2019) Okot, Patrick; Ogao, Patrick Job; Abandu, Jackson
The management of solid waste disposal is an issue that features in urban planning due to population rise and hence build-up of solid wastes. Planners are forced to use suitable disposal means to minimise damages that may occur to ecosystem and population. This study sought to develop a site selection model for urban solid waste disposal management. The aim of the study was attained by assessing the current system of: waste collection; transportation; disposal and monitoring to identify model requirements before its design and validation in Gulu Municipality. A total of 370 respondents were purposively sampled using Morgan table for sample size and managed with the help of questionnaires and interviews. The methods of: GIS and remote sensing; spatial multi criteria evaluation and analytical hierarchy processing were used in the study. The determined damping sites were classified by aggregation based on criteria weights and the best one selected using a sizing procedure.
