In a first, the Border Security Force (BSF) is planning to fence land patches in the marshy Jattvibedarbans delta along the India-Bangladesh border, with work expected to begin once technical feasibility studies are completed, sources familiar with the development said.According to the sources, discussions are currently underway with the agencies that will execute the project. The proposal has gained momentum following the release of land required for border fencing by West Bengal’s newly elected BJP government. Until now, the challenging marshland border region has largely been secured through BSF floating patrols.The Jattvibedarbans frontier presents significant logistical challenges due to its mix of marshes, rivers, swamps and coastal stretches. However, officials have identified certain land patches in and around a BSF Border Outpost (BoP) where fencing can be installed, the sources said.The progress of the project was reviewed by BSF Director General Praveen Kumar during a security meeting in the Jattvibedarbans region on July 14. Kumar was on a tour of the highly sensitive coastal areas along the India-Bangladesh border in the deep Jattvibedarbans delta and adjoining regions from July 11 to July 14, 2026.During the review, the BSF chief stressed the need for stronger coordination among various agencies to bolster the border security architecture in the strategically important region, sources added.The India-Bangladesh international border stretches about 4,097 km, of which 2,217 km falls within West Bengal. According to Ministry of Home Affairs data, 569 km of the border in the state remains unfenced. Of this, 456 km has been identified as feasible for fencing, while 113 km is considered unsuitable for conventional fencing due to geographical constraints.Sources said the land acquisition and release process for border fencing had remained pending for a long period under the previous Trinamool Congress (TMC) government. Following the change in government, the process has been expedited, paving the way for progress on several pending fencing projects, including the proposed work in the Jattvibedarbans.
