Climate Change to Increase Sea Level in Lakshadweep: Study

June 19, 2021

According to a study conducted to project different greenhouse gas scenario, Sea-level will rise around Lakshadweep Islands by 0.4 mm/year to 0.9 mm/year.

Key Findings

As per the study, worst possible inundation scenarios projected for Lakshadweep Islands are similar under different emission scenarios projected. All the islands in archipelago would be vulnerable to impact of sea-level rise.
Smaller islands Chetlat and Amini are expected to have major land-loss.
About 60%-70% of existing shoreline would experience land-loss in Amini and 70%-80% in Chetlat.
Larger islands Minicoy and Kavaratti are also vulnerable to sea-level rise. They will experience land-loss along 60% of existing shoreline.
Sea-level rise effects will have least impact on Androth Island under all emission scenarios.
Only airport in archipelago is located at southern tip of Agatti Island, and has a risk of damage due to sea-level rise.

What does study suggest for protection of island?

Study suggests to have appropriate coastal protection measures and best-practices to formulate planning guidelines. Study proposes for outlook and dimension on future research which will assess directional nature of wave energy, impact of storminess in Arabian Sea region, islands that are exposed & sheltered and amenities like potable water, sanitation etc.
