Abstract
In developing countries, rapid increase in urbanization has increased generation of municipal solid waste, exerting pressure on present solid waste management infrastructure. Old landfill sites are inadequate to cope with a massive quantity of generated waste. In Nagpur city, Maharashtra, India, existing landfill site has reported to cause environmental nuisance, and there is need to identify new landfill site. This paper attempts to integrate geographical information systems (GIS) and multiple criteria decision analysis (MCDA) in landfill site selection process. Based on regional conditions and regulatory rules, fourteen parameters were selected and classified under environmental, sociocultural, and economic criteria. Five regions were identified as suitable alternatives for landfill site, among which ‘Site 1’ in Kuhi region of Nagpur district was selected as the most suitable landfill site. Despite 10% variation in importance weights of parameters, the sensitivity analysis results remained unchanged. Field investigations were conducted to check accuracy of the results.
