- The exponential rise in the urban population of the developing countries in the past few decades and the resulting accelerated urbanization phenomenon has brought to the fore the necessity to develop environmentally sustainable and efficient waste management systems. Landfills being the most sought out solution for municipal solid waste management, siting its location is an extremely complex task. Identification and selection of site for the same depends on many factors and strict regulations. In this study, an attempt was made to determine sites that are appropriate for landfill location by combining geographic information system (GIS) and multi-criteria decision making methods (MCDM) – Analytic Hierarchy Process (AHP).The various factors considered includes depth of ground water table, proximity to surface water sources, soil type, slope, elevation, land use and distance to sensitive sites. Weights were assigned to each criterion depending upon their relative importance and finally a landfill site suitability map was prepared showing the suitable sites taking Thiruvananthapuram as the study area.
