    Abstract

    Atolls are ring shaped coral reefs including a coral rim that encircles a lagoon partially or completely and with or without a coral island/cays on the rim. Most of the world’s atolls are in the Pacific Ocean and Indian Ocean. Lakshadweep islands, Maldives and the Chagos Archipelago are the atolls in the Indian Ocean. Lakshadweep are the only atoll islands in India. They lie scattered in the Arabian Sea between Latitude 8.26° to 12.4° N and Longitude 71.7°-73.75° E, comprising of 36 islands, 3 reefs and 5 submerged banks. These islands consist of coral formations built upon the Laccadive-Chagos submarine ridge rising steeply from a depth of about 1500 m to 4000 m off the west coast of India. While the total land area is 30 sq.km, the length of the coastline is 132 km and lagoon area of 4200 sq.km. Its territorial water spread is 20000 sq.km and it constitutes 0.4 million sq.km to the EEZ of Indian Union. Out of the 36 islands, 11 are inhabited with a population of 64,473 (2011 census). The atolls have 4 distinct biomes comprising of the islands, lagoons, reefs and the Open Ocean. Few threats to the atoll systems are sea level rise, salt water intrusion, reduced availability of fresh water, coral bleaching, disturbances to reef ecosystem, shrinking of livelihood and excessive dependence on external resources, excessive harvest of reef resources etc.
