The Border Security Force (BSF) is reportedly exploring the use of natural deterrents such as snakes and crocodiles to enhance security in riverine and ecologically sensitive stretches of the India–Bangladesh border.
India–Bangladesh Border
The India–Bangladesh border is India’s longest international land boundary, extending approximately 4,096.7 km. It passes through the states of West Bengal, Assam, Meghalaya, Tripura, and Mizoram.
Out of the total border length:
-
Around 3,232 km is already fenced
-
Nearly 864 km remains unfenced
-
About 174 km is classified as non-feasible gaps
Reasons for Unfenced and Non-Feasible Stretches
Several environmental and geographical factors make fencing impossible or ineffective in certain areas.
(a) Riverine Terrain
Major rivers such as the Ichhamati, Raimangal, and Haribhanga flow through the border region. These rivers frequently change course, making permanent fencing structures unstable.
(b) Flood-Prone Conditions
Regular flooding leads to:
-
Damage to fencing infrastructure
-
Continuous shifting of land boundaries
-
Difficult maintenance and repair work
(c) Sundarbans Region
The Sundarbans mangrove ecosystem presents extreme challenges due to:
-
Dense mangrove forests
-
Swampy and unstable terrain
-
High tidal activity and waterlogging
Use of Natural Deterrents
To address these challenges, the BSF is considering the use of natural deterrents like snakes and crocodiles in specific riverine and mangrove zones.
The idea is based on leveraging the existing ecological environment to discourage illegal crossings in areas where human deployment or fencing is difficult.
Purpose of the Strategy
-
To create a natural barrier effect in unfenced riverine areas
-
To reduce dependency on physical infrastructure in hostile terrain
-
To enhance surveillance in remote and inaccessible zones
Significance of the Initiative
If implemented carefully, this approach could provide several advantages:
-
Improved security in difficult riverine stretches
-
Reduced infiltration and smuggling activities
-
Lower infrastructure burden in non-fencable areas
-
Adoption of ecosystem-based border management techniques
About Bangladesh
Bangladesh is a South Asian country located in the deltaic region of the Indian subcontinent. It shares extensive land borders with India on the west, north, and northeast, and a smaller border with Myanmar in the southeast. The country also has a coastline along the Bay of Bengal, which plays a crucial role in its economy, climate, and ecology.
River Systems and Physical Geography
Bangladesh is primarily formed by one of the world’s largest river delta systems. It is shaped by the combined flow of three major rivers:
-
Padma (Ganges)
-
Jamuna (Brahmaputra)
-
Meghna
These rivers, along with their numerous tributaries, create a vast and fertile floodplain.
Nearly 80% of Bangladesh’s land area consists of fertile alluvial plains formed by these river systems.
Biodiversity and Ecological Significance
Bangladesh has rich and globally significant biodiversity, supported by its unique ecosystems.
(a) Sundarbans Mangrove Forest
The Sundarbans is the world’s largest tidal mangrove forest, shared between India and Bangladesh. It is a UNESCO-recognized ecological zone and plays a vital role in coastal protection and climate resilience.
It is also home to the endangered Royal Bengal Tiger, along with diverse species of birds, reptiles, and aquatic life.
(b) St. Martin’s Island
St. Martin’s Island is Bangladesh’s only coral-bearing island, located in the northeastern part of the Bay of Bengal. It is protected as a marine park and is ecologically significant due to:
-
Coral reef ecosystems
-
Marine biodiversity
-
Endangered sea turtles
-
Unique coastal flora and fauna
India–Bangladesh Border Management:
Major Issues
1. Porous Border and Illegal Migration
The India–Bangladesh border is highly porous, which facilitates large-scale illegal migration. This migration is primarily driven by economic disparities, population pressure, and environmental factors such as floods and riverbank erosion in Bangladesh. As a result, it creates demographic pressure, security concerns, and political tensions in bordering Indian states.
2. Smuggling and Transnational Crime
The border is highly vulnerable to smuggling and organized criminal activities, including cattle smuggling, narcotics trafficking, and circulation of fake currency. These activities are often carried out by well-organized networks that exploit difficult terrain and local support systems.
3. Riverine and Difficult Terrain
A significant portion of the border passes through riverine and flood-prone areas, particularly in Assam and West Bengal. The changing course of rivers complicates border demarcation and makes surveillance difficult. Moreover, physical fencing is not feasible in many of these low-lying areas.
4. Border Fencing Challenges
Border fencing faces multiple hurdles such as land acquisition problems and resistance from local communities. Additionally, fencing norms requiring construction at a distance from the zero line result in gaps between the fence and the actual border, leaving some areas vulnerable.
5. Humanitarian and Social Concerns
People living in border areas often face restricted movement, loss of livelihood opportunities, and limited access to basic services. There are also allegations of excessive force by security forces, which contribute to local resentment and alienation.
6. India–Bangladesh Coordination Issues
Although bilateral relations are generally positive, occasional tensions arise due to border killings, disputes over fencing near the zero line, and migration-related sensitivities. These issues sometimes strain coordination between the two countries.
Border Management Measures Adopted
1. Deployment of Border Security Force (BSF)
The BSF is the primary force responsible for guarding the India–Bangladesh border. It conducts round-the-clock surveillance, patrolling, and prevention of illegal activities along the border.
2. Technological Interventions (Smart Border Management)
The government has adopted advanced technologies such as BOLD-QIT (smart fencing system), especially in riverine areas of Assam. This system uses thermal imagers, ground sensors, and radars for real-time monitoring and effective surveillance.
3. Strengthening Border Infrastructure
Efforts have been made to increase the number and density of Border Outposts (BOPs). Additionally, “dark areas” with poor connectivity are being identified and improved. Infrastructure development, including roads and floodlighting, has enhanced border management.
4. Bilateral Cooperation with Bangladesh
India and Bangladesh have strengthened cooperation through mechanisms like the Coordinated Border Management Plan (CBMP). This includes joint patrolling, regular flag meetings, and intelligence sharing, which help in better coordination and conflict resolution.
5. India–Bangladesh Land Boundary Agreement 2015
This agreement resolved long-pending boundary disputes through the exchange of enclaves and demarcation of undefined borders. It has significantly improved mutual trust and reduced conflict along the border.
6. Border Haats (Local Trade Markets)
Border haats have been established to promote legal cross-border trade and reduce dependence on smuggling. They also help in improving livelihoods and strengthening people-to-people ties between the two countries.
Challenges and Concerns in Opting Natural Deterrents
1. Ecological and Ethical Issues
The use of natural deterrents such as snakes or crocodiles for border security raises serious concerns. Introducing or artificially increasing such wildlife populations can disturb ecological balance and disrupt fragile ecosystems. Moreover, it may violate existing wildlife protection laws and ethical norms related to conservation.
2. Proportionality Concerns
Natural deterrents like snakes and crocodiles are inherently unpredictable and cannot distinguish between infiltrators and innocent civilians. This creates significant risks for local fishermen, farmers, and border residents, raising serious humanitarian concerns about the proportional use of force.
3. International Law Angle
The deliberate use of lethal natural hazards as a method of border control may conflict with international humanitarian principles. Such measures could be seen as indiscriminate and excessive, potentially violating norms related to human rights and safe border management practices.
