Abstract
One of the problems faced worldwide is waste management. It involves several
activities, which can be categorized into: collection, transportation and disposal of
waste. Computerizing the processes involved in these activities can help to improve
efficiency and effectiveness in waste management. However, the process of particular
interest and environmental concern is the effective selection of sites for waste disposal
(landfill sites). The current process of selecting landfills in Uganda is manual, costly
and time consuming. This paper presents the design and development of a Spatial
Decision Support Tool as a computer-based technology that can be used to solve the
complex process of landfill site selection for municipal solid waste management in
Kampala and the neighboring Wakiso districts. Several parameters required in
landfill site selection such as an area’s distance from: roads, rivers, lakes, wetlands,
towns, gazetted land, and the soil type, topography, land cover of an area among
others were considered. The tool was developed based on existing literature on landfill
site selection, Spatial Decision Support Systems (SDSS), Geographical Information
Systems (GIS) and Multi-Criteria Evaluation (MCE). The model used by the tool
was designed using ArcView Spatial Analyst 2.0, the user interfaces were designed
using Avenue Programming language and Visual Basic 6.0, and ArcView GIS 3.2a
provided the Database Management System. The results of the tool were validated
using Ground Truthing. The results of this study can be very helpful during the
procurement process of landfill sites; that is, the concerned authorities can save time
and costs associated with inspection and evaluation for bidders whose sites are located
far outside the range of potentially identified areas.
