Sundarbans border fencing plan: BSF’s 90-km proposal raises ecology and security questions
The BSF has explored a 90-km fencing proposal in the Sundarbans along the Indo-Bangladesh border, with concerns over mangroves, wildlife movement and land acquisition.
Key highlights
Direct fact
In July 2026, The Hindu reported that the Border Security Force (BSF) was studying a 90-km physical fencing plan along the Sundarbans mangroves on the Indo-Bangladesh border, a region linked to the Sundarbans Wildlife Sanctuary and the Ichamati river banks.
Key specifics
- Proposed fence length: 90 km along the Sundarbans border stretch.
- The area includes mangroves, creeks, swamps and the Sundarbans Wildlife Sanctuary.
- Wildlife cited in the report includes deer, wild boar, crocodiles and tigers.
- The BSF already uses surveillance cameras and flood-light illuminated fences in parts of the border area.
- Land acquisition and compensation were mentioned for households that may lose land.
Exam lens
Environment + governance question type: match the place and issue, 90-km Sundarbans fence, Ichamati river, mangrove ecology, BSF border management; TNPSC may ask why fencing in a deltaic mangrove zone is controversial.
