Landfill site suitability analysis in Puduserry region, Palakkad, Kerala: An integrated approach using geospatial techniques and analytical hierarchy process

The primary goal of the current study was to identify and discover a suitable site at Pudussery Panchayat in Kerala's Palakkad district for a landfill site in a way that was financially viable, environmentally beneficial, and acceptable to society. The landfill location was chosen based on nine critical criteria transportation network, water bodies, drainage, slope, public assets, settlements, geomorphology, land use/land cover, and depth to groundwater. Analytical Hierarchy Process (AHP) concept and geospatial technology were applied to the analysis. According to the study, of the total 65.14 km², 0.14 km² (0.21%) was highly suitable, 0.18 km² (0.28%) was moderately acceptable, 25.85 km² (39.68%) was less suitable, and 38.97 km² (59.83%) were unsuitable for garbage disposal. The study demonstrated the effectiveness of using GIS technologies in conjunction withAHPto make decisions and locate appropriate disposal sites.
