Lagoons in India Explain in Detail in 10 points

Lagoons in India.


– What are lagoons?

A lagoon is a body of water separated from larger bodies of water by a natural barrier. They are
separated from larger bodies of water by sandbars, barrier reefs, coral reefs, or other natural
barriers. The word “lagoon” derives from the Italian word laguna, which means pond or lake.

There are 17 coastal lagoons located in the coastal region of India

1. East Coast West Coast
2. Chilika lagoon Vembanad lagoon

-Which state is more famous for lagoons in India ?

State of Odisha, Chilika is the largest coastal lagoon in India and the second-largest lagoon
in the world.

-Importance of lagoons in the country :

Coastal lagoons are highly productive ecosystems. They contribute to the overall productivity of
coastal waters by supporting a variety of habitats, including salt marshes, seagrasses, and mangroves.
They also provide essential habitat for many fish and shellfish species, which are the most
commercially important species as well as those with the highest aquatic biomass in these ecosystems.
They are designed to receive, hold, and treat wastewater for a predetermined period of time. If necessary,
they are lined with material, such as clay or an artificial liner, to prevent leaks to the groundwater below.

-The largest lagoon in India :

Chilika Lake is the largest brackish water lake with the estuarine character that sprawls along the east coast of India.
It is considered to be the largest lagoon in India and counted amongst the largest lagoons in the world.

-Smallest lagoon in India :

The island is located at 11° 36′ N I and 72° 11′ E longitude. Though the land area is Small, its lagoon area is 45.61 sq km.
BITRA is the smallest inhabited island in the territory.

-Top 10 lagoons in the World :

1. Chuuk Lagoon, Micronesia.
2. Comino Lagoon, Malta.
3. Kasegaluk Lagoon, Alaska.
4. Laguna Colorada, Bolivia.
5. Marovo Lagoon, Solomon Islands.
6. Milnerton Lagoon, Cape Town.
7. Nanuya Levu Lagoon, Fiji.
8. Pileh Lagoon, Thailand.
9. Aitutaki Lagoon, Cook Islands.
10. Blue Lagoon, Iceland.

-Government schemes for lagoons :


Sub schemes under MIDH – Plastic/RCC based water harvesting structure/ farm pond/construction of community tank (100-meter x 100-meter x 3 meters) For smaller
size ponds/tanks, the cost will be admissible on a pro-rata basis, depending upon the command area.
NMSA – Water Harvesting System for individuals.

Water Harvesting System for communities: Construction of Community tanks / on-farm ponds/check dams/reservoirs with use of plastic/RCC lining on public

Construction of Tube Wells / Bore Wells (Shallow/Medium).
Restoration/Renovation of small tanks.

-Conclusion :

Lagoons protect the ecosystem and aquatic biomass and have a great impact on aquatic habitats. They need to be protected and also more work should be done to
keep them safe i.e with implementing schemes especially for lagoons. Increasing sea levels threaten the coast, tidal lagoons could help coastal communities adapt
and be more resilient to climate change.
