Assessing Landfill Suitability in Flood-Prone Coastal Alappuzha, Kerala Using GIS-MCDA
A study utilized a Geographic Information System (GIS) and Multi-Criteria Decision Analysis (MCDA) approach to evaluate the suitability of potential landfill sites in Alappuzha, a coastal district in Kerala, India. The research specifically focused on areas within Alappuzha that are susceptible to flooding, a critical factor for waste management infrastructure. The GIS-MCDA methodology allowed for the integration of various spatial data layers and decision criteria to identify optimal locations for landfills. This type of assessment is crucial for ensuring that waste disposal sites do not exacerbate environmental risks, particularly in vulnerable coastal regions. The findings are expected to inform local authorities and urban planners in Alappuzha regarding sustainable waste management strategies. By considering flood proneness, the study aims to prevent potential contamination of water bodies and surrounding land from landfill leachate in the event of inundation. This research contributes to the broader understanding of applying advanced spatial analysis techniques to environmental planning challenges in densely populated and geographically sensitive areas.
This study applies advanced spatial analysis techniques to address a critical environmental challenge: siting landfills in flood-prone coastal areas. By integrating GIS and MCDA, the research offers a data-driven framework for decision-making, aiming to mitigate risks associated with waste disposal in vulnerable regions. The methodology systematically weighs multiple factors, including flood susceptibility, which is paramount for preventing potential environmental contamination. This approach moves beyond traditional site selection by incorporating complex environmental variables, thereby promoting more resilient and sustainable infrastructure development. The findings can guide Alappuzha's authorities toward more responsible land-use planning, balancing immediate waste management needs with long-term environmental protection and adaptation to climate change impacts like rising sea levels and increased flooding.
