The aim of present study is to find out suitable sites for solid waste disposal (SWD) in the tropical moist sub-humid region of Bolpur municipality, Birbhum district, West Bengal, India using Remote Sensing (RS), Geographic Information System (GIS) and Analytical Hierarchy Process (AHP) techniques. Saaty’s AHP technique was used to delineate the suitable sites for SWD using thematic layers such as land use/land cover, geology, slopes and soils. The ranks were assigned for each individual sub-criterion of thematic layers and weights assigned to each thematic layer for selection of suitable sites for SWD using Arc-GIS environment. Possible landfill sites were categorized into five classes as highly suitable, suitable, moderately suitable and unsuitable. About 16.43% (1.97 km2) and 28 % (3.42 km2) area in the region show as highly suitable and suitable sites for SWD, respectively. On the other hand, 39.13 % (4.69 km2), 9.49 % (1.14 km2) and 6.38% (0.77km2) area show moderately suitable, less suitable and unsuitable for solid waste dumping.
The present study was devoted to find out suitable sites for solid waste disposal for small town in West Bengal (India).
Landsat-8 and SRTM data was used with conventional maps for preparation of required thematic layers.
Suitable sites were detected using AHP based multi-criteria decision making technique.
Possible landfill sites were categorized into five classes as highly suitable, suitable, moderately suitable and unsuitable.
