Description
Among the various approaches devised in managing municipal solid wastes, landfills remain the final destination of waste irrespective of the technology used in treating it. Incorrect siting of landfill sites could lead to environmental, social and economic cost; hence, appropriate techniques are required in the identification of potential landfill sites. In densely populated areas in Sierra Leone, there is often tension over the location of landfill sites, where 'not in my backyard' campaigns have sparked riots. This article presents a methodological framework for identifying municipal landfill sites in urban areas in Sierra Leone using Bo in Southern Sierra Leone as a case in point. This framework involves a multi-criteria GIS approach that blends two aggregation techniques: Weighted Linear Combination and Ordered Weighted Averaging. Key results show that 83.3% of the study area is unsuitable for municipal landfill. © 2012 Elsevier Ltd.
