Parali 1 a biodiversity-rich uninhabited island of Lakshadweep, part of Bangaram Atoll, disappeared due to coastal erosion and 4 such islands are shrinking. With one island submerged- Lakshadweep is an archipelago of only 36 islands.

Arali 1 Island in Lakshadweep

Bangaram Atoll

  • Bangaram is an atoll in the Union Territory of Lakshadweep with roughly rectangular shape.
  • It is 8.1 km in length with a maximum width of 4.2 km. and with a lagoon area of 36 km2
  • Bangaram atoll is connected to the reef of Agatti through a shallow submarine ridge.

Islands in the Bangaram Atoll

  • Bangaram Island is largest island in the atoll, with a land surface of 0.623 km2 and a long brackish pond in the center fringed by screwpine and coconut palms.
  • South Bangaram Cay, the smallest island in the atoll with a land surface of 0.001 km2 is a small sand cay.
  • Thinnakara is another large island in the atoll with land surface of 0.522 km2
  • Parali 1, Parali 2 and Parali 3 are three small islets at the eastern fringe of the reef with total land surface of 0.089 km2.

Of these, Parali 1 has vanished and others are reducing in size.

Tourism in Bangaram Atoll

The Bangaram Island Beach Resort opened in 1974, but took off only after the Agatti Aerodrome on the nearby Agatti Island was commissioned and regular commercial flights from Kochi were established.

Recent Research on Shirking of Bangaram Atoll Islands

  • The research assessed geo-morphological changes associated with each island for period of 45 years using geospatial techniques of Remote Sensing (₹) and Geographic Information System (GIS) .
  • Parali 1 island was 0.032 km2 in 1968 is now completely inundated.
  • Net erosion is higher in Parali 2 (80 %) , followed by Thinnakara (14.38 %) , Parali 3 (11.42 %) and Bangaram (9.968 %) .
  • Study recommends bio protection strategy using mangroves and conventional physical protection measures from coastal erosion.
  • With islands and coastal areas getting eroded and inundated due to rising sea levels because of global warming- India՚s densely populated coasts and islands remain highly vulnerable.
