World Environment Day 2022: Sundarbans - The Land Of Tigers Faces Threats By Climate Change

A UNESCO World Heritage Site, Sundarbans is one of the world's largest contiguous mangrove forest spread over an area of 10,000 square kilometers, 60 per cent of which lies in Bangladesh and the rest in India. According to Sundarban National park India Official website, the 4000 sq. km of Sundarbans is on the Indian side has 102 islands, out of which 54 are inhabited and the rest are covered with forest.

The unique landscape of Sundarbans with its intricate tidal waterways, rivers, creeks, backwaters, low lying islands, swamps and stretches of mudflats, provides a diverse habitat for various species of plants and animals, be it terrestrial or aquatic.

Home to the endangered Royal Bengal Tiger, it is the only mangrove tiger habitat in the world. According to World Heritage Convention (UNESCO), apart from the tiger, some of the other threatened species of the area are estuarine crocodile, Gangetic Dolphin, Olive Ridley Turtle and Water Monitor Lizard.

One of the reasons why it is tagged as the UNESCO world heritage site is because it is the only remaining habitat in the lower Bengal Basin, which has a wide variety of faunal species, states World Heritage Convention (UNESCO).

Due to the lack of availability of freshwater in Indian Sundarbans, species like Sundari, which used to be dominant specie, is disappearing. Gradually, all fresh water loving mangrove species are now getting replaced with the ones that can withstand salinity. According to World Wildlife Fund, four islands have vanished in Sundarbans due to the effects of climate change in the last 25 years - Bedford, Lohachara, Kabasgadi, and Suparibhanga. Lohachara became well-known as the world's first inhabited island to be submerged in 2006.
