The selection of an appropriate landfill site is a complex issue due to the involvement of numerous criteria and constraints. A non-engineered and unsuitable site can harm the environment, society and economy of an area. This paper focuses on the application of Geographic Information System (GIS) and Analytical Hierarchy Process (AHP), a multi-criteria decisionmaking technique, to determine suitable landfill sites. A total of nine parameters have been used namely; groundwater depth, slope, geology, existing landfill site, drainage density, road network, land use and land cover (LULC), railway lines and airport. The weights were calculated using AHP. A landfill site suitability map was generated with 5 classified areas namely; most unsuitable (0.07%), unsuitable (5.42%), less suitable (23.94%), moderately suitable (58.24%) and most suitable (12.38%). The areas identified in the study can be used by policymakers in both urban as well as rural developmental planning and waste management. Using the patches of land from the landfill suitability map, a decentralised community-based landfill model can also be adopted to minimize and possibly eliminate the need for large landfill sites.
