Intriguing questions arise over the size of the Sundarbans, the world’s largest mangrove forest, as environmental challenges threaten its UNESCO heritage status. Climate change, pollution, unregulated tree felling, and authorities’ indifference pose risks to the Sundarbans’ environment and biodiversity.
Despite a consistent reported area of 6,017 sq-km since 1947, recent changes have sparked curiosity. Emerging shoal islands like Bangabandhu Char and shifts in areas like Dim Char raise concerns about the Sundarbans’ evolving landscape. While tiger and deer populations show positive trends in surveys, the overall impact on biodiversity remains uncertain.
Efforts are underway to safeguard the Sundarbans, including awareness campaigns, nylon net installations, and camera surveys. A 20km nylon fence project aims to protect villages from wild animals, with the latest results expected on International Tiger Day, July 29.
Approximately 31.1% of the Sundarbans consists of riverbeds, inlets, bills, and water, housing 120 fish species and 31 endangered animals. Ongoing threats, such as ship-induced light and noise, jeopardize the forest’s delicate ecosystem.
Despite the Sundarbans being declared a UNESCO World Heritage Site in 1977, challenges persist. A rise in sea levels, river erosion, illegal settlements, and uncontrolled tree felling have led to a 28.75% loss of Sundari trees. A recent Unesco delegation’s visit in 2023 highlights continued concerns, including identified threats from 2019.
Fishermen contribute to conservation through permits and regulations, but outdated laws and unauthorized entries by various government bodies pose challenges. A three-year Sundarbans Tiger Conservation Project aims to address these issues, focusing on tiger census, mounds for shelter during calamities, and nylon fences.
While the government shows increased awareness, calls for an official Sundarbans Day and stronger anti-poisoning policies emphasize the need for continued dedication to safeguarding this vital ecosystem.
