Kochi is likely to go three feet underwater by the end of this century, as per the IPCC report (Climate change 2014: impacts, adaptation and vulnerability, Cambridge University Press [1]). The average sea level around the world rose during the twentieth century and continues to rise primarily due to global warming. This phenomenon results in various consequences, such as heightened flood risks, saltwater damage to land and water resources, and changes in landforms like wetland erosion and the loss of habitats. While it is crucial to consider the potential effects on human communities and ecosystems in the twenty-first century, these impacts remain uncertain. Likewise, the rising sea levels present a significant challenge for the coastal areas of Kochi city. Therefore, this study concentrates on assessing the vulnerability of the coastal region by examining geological, physical, and socio-economic factors. Moreover, the coastal vulnerability assessment reveals the most physically and socially at-risk areas within the Kochi City Region. An asset inventory and exposure assessment for both vulnerable zones has been done to later develop region-specific adaptation and resilience solutions.
