Context: A recent study in Conservation Biology has revealed that Anti-Depredation Squads (ADS) in Assam, designed to reduce human-elephant conflict, are associated with a 200-300% increase in accidental elephant deaths.
About Human-Wildlife Conflict (HWC)
What it is?
• Human-Wildlife Conflict refers to negative interactions between humans and wild animals, resulting in undesirable consequences for both. This includes loss of human life, livestock predation, and crop damage on one side, and retaliatory killing, habitat destruction, or accidental deaths of wildlife on the other.
Data & Statistics on Conflicts:
• Elephant Mortality: India loses approximately 100 elephants annually to non-natural causes like electrocution, train hits, and poaching.
• Human Toll: Over 500 people are killed annually in India due to encounters with elephants, primarily in states like Odisha, West Bengal, and Assam.
• Economic Impact: Millions of hectares of crops are damaged every year, often pushing marginal farmers into deep debt.
• Scale of Intervention: In Sonitpur alone, the presence of organized squads (ADS) was linked to 14 additional elephant deaths over 14 years compared to non-ADS areas.
Need for Balancing Human-Wildlife Conflict:
• Economic Security for Farmers: Conflicts often destroy the entire annual livelihood of rural families.
Example: In the Sonitpur tea gardens, elephants frequently range over croplands, necessitating organized guarding to prevent total financial ruin for villagers.
• Conservation of Keystone Species: Elephants are ecosystem engineers; their loss disrupts forest health.
Example: The 2-3x increase in accidental deaths in ADS-active villages threatens the long-term viability of Assam’s 5,000-strong elephant population.
• Psychological Well-being and Safety: Constant fear of wildlife attacks reduces the quality of life in fringe villages.
Example: The formation of ADSs was originally intended to give villagers safety in numbers, reducing the panic that leads to violent retaliatory killings.
• Maintaining Ecological Corridors: Balancing conflict ensures that traditional migratory paths remain functional.
Example: When elephants are frightened by ADS searchlights, they stray from safe corridors into dangerous linear infrastructure like railway tracks.
• Reducing State-Community Friction: Effective management mends the mistrust between the Forest Department and local communities.
Example: ADSs in Assam incentivized communities to cooperate with the Forest Department rather than resorting to illegal traps or poisoning.
Initiatives Taken So Far
• Anti-Depredation Squads (ADS): Community-led volunteer groups equipped with searchlights and firecrackers to drive away elephants.
• Project Elephant (1992): A central scheme providing financial and technical support to states for elephant management and corridor protection.
• Linear Infrastructure Guidelines: Measures like underpasses and overpasses on highways and railways to allow safe wildlife passage.
• Early Warning Systems (EWS): Use of SMS alerts, thermal sensors, and Elephant cells to track herd movement and alert villagers in real-time.
Challenges Associated:
• The Landscape of Fear: Aggressive deterrents can backfire by causing animals to lose caution.
Example: The study shows frightened elephants in Assam are more likely to fall into ditches or be hit by trains because they are distracted by pursuers.
• Fragmented Habitats: Developmental projects break continuous forests into small patches, forcing animals to cross human settlements.
Example: The loss of forest cover in Sonitpur over decades has forced elephants to range through tea plantations and banks of the Brahmaputra.
• Unsystematic Responses: Lack of training turns organized squads into local mobs.
Example: A 2019 Union Environment Ministry review noted that ADS operations often involve unsystematic firing, which reduces their effectiveness.
• Underreporting and Data Gaps: Actual conflict levels are often higher than official records due to poor department-community relations.
Example: The study had to adjust for underreporting bias because villagers often hide conflict details to avoid legal scrutiny.
• Seasonality of Conflict: Deterrents are often temporary, and animals eventually adapt to them (habituation).
Way Ahead
• Shift to Passive Deterrents: Move away from firecrackers toward non-threatening barriers like bee-fencing or chili-based deterrents.
• Rigorous Impact Evaluation: Adopt the study’s recommendation to pause the rapid expansion of ADSs until their mortality impact is statistically cleared in other states.
• Community-Led Insurance: Implement rapid crop-compensation schemes to reduce the urge to chase among farmers.
• Smart Infrastructure: Install sensor-based speed restrictors for trains in identified elephant corridors to prevent accidental deaths.
• Habitat Restoration: Prioritize the reforestation of lost corridors in priority landscapes like Sonitpur to keep elephants away from human habitations.
Conclusion:
The unexpected findings from Assam demonstrate that well-intentioned conservation strategies can inadvertently increase wildlife mortality if they rely on fear-based deterrence. Effective conflict management must transition from organized chasing to science-backed, passive co-existence strategies. Balancing the safety of rural communities with the preservation of India’s heritage animal requires a data-driven re-evaluation of current national guidelines.
