Lakshadweep Coral Reefs see 50% Decline in 24 years Key Findings of Reef Monitoring Prog.

  • Coral cover in Lakshadweep dropped by roughly 50%% from 37.24% to 19.6%.

CAUSES

  • Marine Heat waves
  • Warm and sustained sea surface temperature
  • El Nino Southern Oscillation (ENSO
  • Oceano-atmospheric condition in Southern Equatorial Pacific Ocean.
  • Events in 1998, 2010, 2016.

Besides, other Causes and Trends

  • Bleaching events caused GRADUAL REEF degradation.
  • Local conditions like wave exposure and depth also. influence reef recovery.
  • Recovery improves after 6+ years of bleaching free periods indicating the need for long-term climate stability.

#    Researchers tracked reefs at Agatti, Kadmat and Kavaratti (Lakshadweep Archipelago).

Examination Perspective

Q.1   Coral reef decline is an indicator of marine ecosystem. Examine the causes, consequences and suggest            strategies to mitigate in Indian context
