A swampy mangrove delta with water channels and a simple border fence segment near dense vegetation.
Key takeaways
  • The Border Security Force is considering whether a fence can be built in the Sundarbans without causing unacceptable environmental damage.
  • The Sundarbans is a swampy, tidal and ecologically fragile landscape that complicates conventional border fencing.

The Border Security Force is considering whether to build a fence in the Sundarbans. The proposal matters because the Sundarbans is both a strategic border zone and one of India’s most fragile coastal ecosystems.

The terrain is swampy, tidal and shaped by shifting water channels and unstable soil. Conventional fencing is therefore difficult to construct and maintain, and it can also damage mangrove habitats and obstruct wildlife movement.

The UPSC angle · GS3 · GS1

UPSC can frame the Sundarbans case as a border-management question that tests whether candidates can balance security needs with environmental safeguards, especially in mangrove deltas and tidal terrain.
