Effective landfill site selection is crucial for sustainable waste management and minimizing environmental risks. Geographic Information System (GIS)-based approaches have become essential tools in evaluating potential landfill locations by integrating geological, environmental, and geo-environmental criteria. This study focuses on the selection of an optimal landfill site for Feyzabad, Razavi Khorasan, Iran, using a GIS-based multi-criteria decision analysis (MCDA). The methodology involves identifying suitable landfill sites by considering geological, environmental and Geoenvironmental factors. Data from remote sensing, topographic maps, and field surveys were processed using GIS spatial analysis tools to generate suitability maps. Analytical Hierarchy Process (AHP) was applied to weight different factors based on their relative importance. The results highlight the most suitable landfill locations that comply with regulatory and sustainability standards while minimizing environmental hazards. The findings of this study provide a scientific and practical framework for policymakers and urban planners to make informed decisions regarding waste disposal infrastructure. The GIS-based methodology ensures a systematic and objective selection process, reducing potential socio-environmental conflicts. Future research should consider additional socio-economic factors and climate change projections to further refine landfill site selection strategies.
