The Border Security Force (BSF) Headquarters has directed its field units to conduct a feasibility study on the deployment of crocodiles and venomous snakes along a 371-kilometre stretch of the India-Bangladesh border that remains unfenced due to riverine terrain. This unconventional approach to border security is intended to serve as a natural deterrent to illegal infiltration in areas where physical fencing is impractical.\n\nThe 371 km of unfenced India-Bangladesh border consists largely of river channels, wetlands, and floodplains where traditional infrastructure such as barbed wire fencing and floodlights cannot be effectively deployed. Criminal networks and trafficking groups have historically exploited these natural gaps in border security.\n\nBSF's proposal involves studying whether crocodiles — indigenous to some of these riverine areas — and venomous snake species could be encouraged or introduced into these stretches to create a biological barrier. The study is to assess the feasibility, ecological impact, and practical implementation challenges.\n\nThe initiative is currently at the feasibility-study stage only. No deployment decision has been made. Officials and wildlife experts have raised significant concerns about civilian safety, as these border areas are inhabited by local fishing and farming communities who regularly use rivers and riverbanks for their livelihoods.\n\nConservation groups have also questioned whether artificially introducing or concentrating reptile populations would violate wildlife protection laws and cause ecological disturbances. The BSF has acknowledged these concerns and stated that the study will comprehensively evaluate safety and ecological risks before any recommendation is made.\n\nThe proposal reflects the broader challenge of securing India's porous riverine borders using non-conventional methods given the limitations of physical infrastructure.
