BSF’s Sundarbans Fencing Proposal: Balancing Border Security and Ecological Conservation

Context

The Border Security Force (BSF) has initiated a feasibility study to examine the installation of physical fencing along a 90-km stretch of the India – Bangladesh border in the Sundarbans. The proposal aims to strengthen border security by preventing illegal activities while considering the ecological sensitivity of the region. The project follows an earlier proposal to release snakes and crocodiles into border rivers as a deterrent against illegal crossings.

Highlights

• The proposed fencing will cover a 90-km stretch of the Sundarbans mangrove ecosystem, an area known for its rich biodiversity, including the Royal Bengal Tiger, which inhabits the brackish water ecosystem.
• Construction is expected to be challenging due to the region’s dense mangrove forests, tidal creeks, and swampy terrain, which make many areas inaccessible.
• The government has also approved the construction of floodlight-illuminated border fences in the region.
• According to BSF officials, the Sundarbans Wildlife Sanctuary will remain untouched, and the fencing is being considered only along the banks of the Ichamati River in the northern reaches.
• The BSF has stated that landowners affected by the project will be compensated.

Concepts & Issues

Security Perspective

• The fencing is intended to strengthen surveillance and curb illegal cross-border activities along the porous India–Bangladesh border.
• Some experts argue that fencing in non-protected stretches may enhance border management without significantly harming the ecosystem if implemented carefully.

Ecological Concerns

• Environmental experts caution that fencing could restrict the movement of wildlife, including deer, wild boar, crocodiles, and tigers, which frequently move across rivers and sandbanks.
• The proposal raises concerns because the fluid ecology of the Sundarbans is characterised by constantly shifting rivers, tidal channels, and sandbanks, making permanent infrastructure difficult to sustain.
• Experts argue that the mangrove ecosystem has already been affected by illegal fisheries and construction activities in non-protected areas, and additional infrastructure could further increase ecological stress.

Social Concerns

• Concerns have been raised that infrastructure projects in the region may displace local communities, with rehabilitation and compensation remaining key issues highlighted by experts.

Way Forward

• Ensure that border security infrastructure is planned without compromising the ecological integrity of the Sundarbans.
• Conduct comprehensive environmental assessments before finalising the fencing alignment.
• Minimise impacts on wildlife movement by carefully selecting locations and avoiding ecologically sensitive stretches.
• Ensure fair compensation and effective rehabilitation for people affected by land acquisition.
• Adopt a balanced approach that integrates national security objectives with biodiversity conservation and community welfare.
