Tamil Nadu Initiates Project to Save Kariyachalli Island from Erosion
DEFENSE
The Tamil Nadu government has begun a project to save Kariyachalli Island, which has lost 71.37% of its landmass since 1969. The initiative involves deploying 8,500 artificial reefs to combat erosion and enhance biodiversity.
This process, expected to take 18 months, is part of a broader effort to protect the Gulf of Mannar islands, vital for coastal defense and ecology. A budget of ₹50 crore has been allocated for this project, which will include monitoring for five years post-completion.
