Coastal Vulnerability Index – UPSC Prelims

Coastal Vulnerability Index:
  • It is a coastal vulnerability assessment for the entire Indian coast at States level.
  • Coastal vulnerability is a spatial concept that identifies people and places that are susceptible to disturbances resulting from coastal hazards.
  • The maps will determine the coastal risks due to future sea-level rise based on the physical and geological parameters for the Indian coast.
  • The CVI uses the relative risk that physical changes will occur as sea-level rises are quantified based on parameters like:
    • Tidal range
    • Wave height
    • Coastal slope
    • Coastal elevation
    • Shoreline change rate
    • Geomorphology
    • Historical rate of relative sea-level change.
  • Coastal vulnerability assessments can be useful information for coastal disaster management and building resilient coastal communities.
