A Wetland Under Pressure
Authorities have issued a 13-point directive aimed at protecting Tanguar Haor, the vast freshwater wetland in Sunamganj district that serves as one of Bangladesh’s most ecologically and culturally significant natural sites. The directive covers restrictions on fishing methods, limits on tourist activity, and measures to prevent encroachment, reflecting growing concern that the haor’s fragile ecosystem is being strained by overuse and inadequate enforcement.
The move is significant because Tanguar Haor is not simply a scenic destination. It is a Ramsar site, internationally recognised since 2000 as a wetland of global importance, and it functions as a critical nursery for fish, a seasonal home for migratory birds, and a livelihood base for tens of thousands of people living along its margins.
What Tanguar Haor Actually Is
Spread across roughly 100 square kilometres in Sunamganj’s Tahirpur and Dharmapasha upazilas, Tanguar Haor is a network of interconnected beels, or water bodies, that fills dramatically during the monsoon and contracts to a series of deeper channels and pools in the dry season. At its peak flood stage, the haor takes on the appearance of an inland sea, with villages sitting on raised earthen platforms and travel happening almost entirely by boat.
The haor sits at the foot of the Meghalaya hills in India, which means it receives an enormous volume of runoff during the rains. This makes it one of the most productive freshwater ecosystems in the entire Bengal delta. Over 140 species of freshwater fish have been recorded here, along with more than 200 species of birds. During winter, the haor becomes a staging ground for migratory waterfowl arriving from Central Asia and the Himalayas, including various species of ducks, herons, egrets, and the occasional rare visitor that draws birdwatchers from across the country.
The Communities That Live With the Haor
Several hundred thousand people in the surrounding area have historically depended on Tanguar Haor for fishing. In 2000, the government transferred management of the haor to the local community under a co-management framework, one of the first such arrangements for a wetland in Bangladesh. The 13-point directive is partly a response to ongoing tensions around enforcement and outside pressure on the resource.
Tourism, Beauty, and the Risk That Comes With It
Over the past decade, Tanguar Haor has become one of the most popular ecotourism destinations in Bangladesh. Travellers typically reach Sunamganj town and then hire a wooden houseboat to spend a night or two on the water. The problem is that this popularity has brought a surge of visitors who are not always careful about what they leave behind. Plastic waste, noise from motorised boats, and illegal fishing have all become concerns that the new directive seeks to address.
Why This Place Matters Beyond Its Borders
Bangladesh has 114 haors in the northeastern region, but Tanguar stands apart in terms of biodiversity and international recognition. Its Ramsar designation places it alongside wetlands considered too important to lose. The new directive, if enforced, could make a real difference. For anyone planning to visit, the best time is between November and February, when migratory birds are present and the full character of the landscape is revealed.
