Border Security Force considers physical fencing along Sundarbans eco-sensitive zone

This topic highlights a classic conflict between border security infrastructure along the Indo-Bangladesh border and ecological conservation in the Sundarbans eco-sensitive zone, making it directly relevant to GS3.

Notes

• Border Security Force (BSF) initiated a feasibility study to construct physical fencing along a 90-km stretch of the Sundarbans mangroves along the Indo-Bangladesh border.
• The government has sanctioned flood-light illuminated fences as a non-physical barrier in the region.
• Proposed physical fencing is envisaged along the banks of the Ichamati river in the northern reaches of the Sundarbans.
• BSF officials stated that the Sundarbans Wildlife Sanctuary will remain untouched, biodiversity will not be impacted, and land losers will receive compensation.
• Ecological concerns raised include disruption of natural movement of fauna such as tigers, deer, wild boars, and crocodiles across rivers and forest sandbanks in a fluid ecosystem.
• Terrain challenges include thick mangrove forests, creeks, and swamps that render physical construction highly inaccessible.
• Socio-economic concerns highlight potential dispossession of vulnerable local populations, drawing from past issues with land acquisition for embankments.
• Proponents argue regulatory control via fencing in non-protected areas could curb illegal fisheries and unregulated construction that threaten mangrove habitats.
