Sundarbans at stake as erosion shrinks forest land
The Sundarbans, the world's largest mangrove forest and a UNESCO World Heritage Site, is facing an alarming threat as relentless riverbank erosion steadily devours its landmass, displacing communities, destroying infrastructure and shrinking vital forest cover.
Spanning the delta region of the Padma, Meghna and Brahmaputra river basins, the Sundarbans is a crucial ecological zone shared between Bangladesh and India.
It is home to rich biodiversity, including the endangered Royal Bengal tiger. But continuous erosion is rapidly reshaping the landscape, with islands and coastal land disappearing into the sea.
Vanishing Land and Lost Infrastructure
Jetties, Forest Department offices and other vital infrastructure are being washed away, forcing officials to abandon their posts.
In September last year, the East Sundarbans Division sought assistance from the Bangladesh Water Development Board (BWDB) to curb erosion at nine vulnerable locations.
Although sand-filled geo bags were placed in front of the Forest Office to mitigate the damage, the measure has largely proven ineffective.

According to sources in the Forest Department, the situation has worsened over the years, swallowing entire forested areas along with their trees.
The jetty at the Dubla Forest Office, several drinking water ponds, cyclone shelters and freshwater reservoirs at Meherali Char have already been lost to the rising tides.
Meanwhile, the old rest house and jetty at Katka have disappeared, and the two-storey Bogi Forest Office building is on the brink of collapse into the river.
“The forest land is continuously being destroyed, and many trees have already vanished. The old rest house at Katka has gone into the sea, and numerous areas deeper into the Sundarbans have been submerged,” said Soyebur Rahman Suman, in charge of the Katka Sanctuary Centre, a popular tourist spot in the Sundarbans.
A Sabur, an officer at Bogi Forest Station, echoed similar concerns. “Our office-cum-barracks are also at risk of being submerged. Staff have been forced to move to alternative shelters to avoid further danger.”
Despite efforts to control the damage, the situation has not improved. “The Water Development Board placed sandbags in September and October last year to prevent erosion, but they have not been effective,” added Sabur.

Nine Critical Zones Under Threat
Forest officials have identified nine key locations that are severely affected by erosion:
· Kachikhali Sanctuary Centre
· Katka Sanctuary Centre
· Chandeshwar Patrol Outpost
· Jelepalli Dubla Patrol Outpost
· Bogi Forest Station
· Jhapsi Patrol Outpost
· Jongra Patrol Outpost
· Karamjal Wildlife Breeding Centre
· Shuarmara Patrol Outpost
Rana Deb, Sharankhola Range Officer of the Eastern Sundarbans Division, noted that while some forest areas are eroding, new chars (sandbanks) are forming in other river regions. But this offers little consolation given the immense destruction already suffered by the Forest Department, particularly after Cyclone Remal.
Funding Shortages Hindering Protection Efforts
Abu Raihan Md. Albunni, Executive Engineer of BWDB in Bagerhat, admitted that financial constraints have hindered further erosion prevention efforts. “Sand-filled geo bags were placed in front of Bogi Forest Station, but due to budget limitations, no action has been taken in other erosion-affected areas,” he said.
Divisional Forest Officer of the East Sundarbans Division, Kazi Muhammad Nurul Karim, expressed grave concern over the worsening crisis, attributing it in part to climate change.
“We sent a letter to the Executive Engineer of BWDB in September last year, requesting urgent intervention at nine locations. Although some geo bags were placed in Bogi, they were ineffective in halting the erosion,” he said.

Alarming Shrinkage of the Sundarbans
A World Bank report, Coping with Climate Change in the Sundarbans: Lessons from Multidisciplinary Studies (2020), presents alarming evidence of the forest's shrinking footprint. The total area of the Sundarbans (including both Bangladesh and India) measured 11,904 sq km between 1904 and 1924. By 1967, it had reduced to 11,663 sq km, and in 2016, it further declined to 11,506 sq km.
According to various sources, the Sundarbans is crisscrossed by approximately 450 rivers and canals, stretching about 350 km in total length. Natural tidal activity continuously reshapes these waterways, causing both erosion and deposition. However, the extent of land loss in the last century has far outpaced natural recovery, posing an existential threat to the forest and its inhabitants.
Need for Urgent Action
The relentless erosion of the Sundarbans demands immediate intervention from policymakers, conservationists and international stakeholders. Without robust mitigation strategies and sustainable erosion control measures, the continued loss of land will exacerbate climate vulnerability, displace more communities, and push the region’s fragile ecosystem further towards collapse.

Riverbank erosion leaves Gashial residents on the edge
In the remote Gashial mouja of Magura district, riverbank erosion along the Garai is a frequent affair.
Every monsoon, residents of the mouja see the ground literally disappear into the raging Garai. And over the past couple of years, the erosion has washed away several houses in the area, rendering hundreds homeless.
The residents allege that local authorities have never paid heed to their urgent pleas for measures to prevent erosion of the river bank. As a result, the house of Ajit Sheikh is the last structure standing on the edge.

According to local resident Rustom Biswash, a freedom fighter, a large portion of Gashial mouja has been devoured by the river over the past 50 years. "Erosion is a perennial affair here," he says.
"If the authorities concerned do not act immediately, then the mouja could soon become a barren land," he adds.
In fact, the residents say that some 1,500 acres of land have disappeared in the mouja in the past few years and nearly 35-40 families in Char-Chougachi village are living with the fear of their houses being swept away.

Owing to poverty and occupational reasons, many people in the village live near the river, which makes them a victim of erosion.
The local administration though says that it has dumped more than 15,000 sandbags on the riverbank to prevent erosion in the area. "The sandbags will prevent erosion to a large extent," says Anwar Hossain, a sub-contractor of the Water Development Board.

The local residents, however, have demanded that the authorities build a river embankment in the area to put an end to the problem of riverbank erosion once and for all.
Solaiman Molla, president of River Erosion Protection Committee, says that this is the first time in 50 years that the authorities concerned have placed sandbags, "which is good news for the residents living here"
Mohammad Zakir Hossain, chairman of Dariapur Union, said already the dredging and sand-lifting work have been done.

Living in fear of the mighty Padma
Originally a resident of the Isaeel Shibrampur area in Goalundo upazila's Daulatdia union, Jalil Sikder now lives with his family in a hutment on a Good Samaritan's land in Nasir Sardar Para.
"We were rendered homeless after our house was washed away by the mighty Padma river in front of our eyes last year. Thanks to a benevolent person in Isaeel Shibrampur, we have a roof over our heads," he says.
Riverbank erosion is a common problem along the Padma during the rainy season.
And Jalil is also not the lone sufferer. Over the years, several families in the riverine areas of the upazila's Daulatdia and Debgram unions have been rendered homeless by such engulfing calamity.

Some 2,000 families still living in the riverine areas of the two unions are now spending sleepless nights. Their fears are tangible, with monsoon rains barely a week away.
"Every day, the river is washing away some three to four bighas of land. The erosion aggravates during the monsoon when the Padma overflows its banks. It's high time that the authorities took safety measures without any delay," says Hazrat Sheikh, a resident of Devgram's Munshibazar area.
"In the past three years, some 300 families have been forced to abandon their houses in Devgram. What we get from the local authorities after every monsoon is only assurances of better preparedness for next year," says Ruby Khatun, a resident of Aziz Sardar Para.

Upazila Chairman Mostafa Munshi admits the problem the riverine areas face during the monsoon. "I have sought Rajbari-1 MP Kazi Keramat Ali's help in this regard," he says.
According to the Rajbari-1 MP, all preparations are underway for starting the construction of an embankment from Ferry Ghat to Debgram Antarmor to prevent erosion.
"The Executive Committee of the National Economic Council will soon begin work on Daulatdia and Paturia Ghat modernisation projects worth around Tk 650 crore," he says.
Upazila Nirbahi Officer (UNO) Azizul Haque Khan recently visited the affected areas. "For the time being, the Water Development Board is placing sand bags along the ferry ghat," he says.
