Context

Recently a study report published in scientific Journal Nature Climate Change says that Climate change poses an existential threat to the world's sandy beaches.

Background

  • Coastal erosion is the wearing away of land and removal of beach sediments by high winds, drainage, wave action, wave currents, and tidal currents. Coastal morphodynamics studies the erosion and sediment redistribution in coastal areas. It is caused by corrosion, hydraulic action or abrasion.
  • Coastal erosion can be either a:
    • rapid-onset hazard (occurs very quickly, a period of days to weeks)
    • slow-onset hazard (occurring over many years, or decades to centuries).
  • The beaches and shorelines in India serve multidimensional needs such as seaport for maritime commerce, space for residential & commercial structures, recreational purposes etc.
  • Developmental activities along the coastline have increased and the trend is expected to continue in the decades to come.  Similar to any other maritime country, India’s long peninsular region constantly battles erosion.
  • The developmental activities are often carried out without a clear understanding of the coastal dynamics. This leads to a long term, in the worst cases, permanent damage particularly to the local communities.
  • According to the Ministry of Environment, Forest and Climate Change (MOEFCC) 40% of India’s coastline is subjected to high, medium or low coastal erosion.
