Reviving Kariyachalli Island: Tamil Nadu’s Bold Plan

A Mission to Save a Disappearing Island

Villagers from Tuticorin are on a special mission. They are working to bring Kariyachalli Island back to life. This island is in the Gulf of Mannar. The Tamil Nadu government has launched a Rs 50 crore project to restore it. Kariyachalli is one of 21 delicate islands in the Gulf of Mannar Marine National Park.

Why Kariyachalli Island Matters

Kariyachalli Island is a small strip of land. It lies between India and Sri Lanka. The island acts as a natural shield. It protects against cyclones and tsunamis. Rich coral reefs and seagrass beds surround the island. These support a wide range of marine life. They also provide jobs for thousands of fishermen.

The Island’s Struggle

The island has lost a lot of its land. Over 71% has disappeared since 1969. Back then, it was 20.85 hectares. Now, it’s just 5.97 hectares. Rising sea levels and damaged coral reefs and seagrass are to blame.

The Government’s Conservation Plan

The government’s plan is part of the TN Sustainably Harnessing Ocean Resources (TNSHORE) program. The goals are clear:

• Strengthen climate resilience
• Protect marine life
• Support sustainable jobs for coastal communities

Building Artificial Coral Reefs

The government will use 8,500 artificial coral reef modules. These are designed by IIT Madras. The modules will:

• Guard the island’s shoreline
• Less wave energy
• Help sediment build-up

These structures are made of ferrocement and steel. They will be placed underwater. Corals will be added to them. Local fishermen will help place these structures. The modules will act as wave breaks. They will also create new marine homes.

Bringing Back Coral Reefs and Seagrass

The plan includes restoring:

• Two acres of damaged coral reef
• Three acres of seagrass beds

These ecosystems are vital for:

• Storing carbon
• Protecting biodiversity
• Guarding the shoreline

Local Communities Pitch In

Villagers from Sippikulam and Pattinamaruthoor are involved. They will get:

• Training
• Support for eco-tourism
• Help with alternative jobs

Looking Ahead

The project aims to restore the island’s land. It will also improve the island’s ecology. Plus, it will open up eco-tourism opportunities. If successful, this project could save the island. It might even stop the island from disappearing by 2030.
