Description Sea level rise is one of the evident ill effects of climate change. As per
the fifth assessment report of IPCC the rate of sea level rise has
increased in recent years as compared to the previous years. The rapid
rise in sea level can have devastating effects on the densely populated
coastal areas, mainly by way of inundation of low lying habitats.
Inundation of highly populated coastal areas exposes the location to
coastal hazards and increases the risk to both life and belongings of
people at the location. Therefore, identification of vulnerable areas
becomes necessary for coastal zone management. The present study
maps the Low Elevation Coastal Zones (LECZ) of Andhra Pradesh and
Tamil Nadu and estimates the vulnerability of each coastal village
based on population and elevation. The coastal villages with high
percentage of low elevation zones and high population density are the
most vulnerable areas and a vulnerability index is formulated as a
product of these two variables. Landforms along Andhra Pradesh and
Tamil Nadu coast include low lying alluvial plains, bays, tidal mudflats,
creeks, ridges, bars, spits, mangrove swamps, marshes, and lagoons,
which are subject to sea level rise. Maps for the study were produced
using ArcGIS 10. The boundary maps were collected from the
DataMeet project and the elevation data from ETOPO1. Population
density data were collected from the NASA Socioeconomic Data and
Applications Center (SEDAC). Increase in water level leads to higher
rates of erosion that result in beach loss, enhancing the vulnerability of
the coastal area to hazards. The analysis shows that Losari Gutlapadu
and Sadayankuppam are the most vulnerable villages in Andhra
Pradesh and Tamil Nadu respectively. Mapping of the vulnerable areas
act as advisories and can help the state governments to develop
mitigation strategies.
