Vultures and Public Health: Preventing Future Pandemics
Why in News?
- As the National Action Plan for Vulture Conservation (2016–25) nears its end, attention is turning to how vultures can be integrated into pandemic preparedness strategies.
- Vultures, South Asia’s most efficient waste managers, play a crucial role in preventing zoonotic disease outbreaks.
Vultures and Pandemic Prevention
- Carcass Disposal: Vultures consume animal carcasses rapidly, preventing pathogens (anthrax, botulinum, rabies) from spreading.
- First Line of Defence: By limiting exposure of stray dogs, rats, and humans to decaying carcasses, vultures reduce zoonotic spillover risk.
- Cost-Effective: Conservation requires far less investment than the cost of responding to pandemics.
- Community Role: Local communities near carcass dumps can be vital partners in surveillance and awareness.
India’s Vanishing Vultures & Public Health Risks
- Population Decline: India once had 40 million vultures in the 1980s. Since 1990s, numbers fell by 95%+ due to diclofenac (toxic veterinary drug).
- Ecological Collapse: Absence of vultures → carcass piles → rise in stray dogs and feral animals → higher rabies transmission.
- Biodiversity–Health Nexus: Declining vulture numbers = weakened natural disease buffer → increased pandemic risks.
Central Asian Flyway (CAF) & Regional Linkages
- CAF: Migratory route spanning 30+ countries, used by vultures, raptors, and millions of birds.
- Links ecosystems and transboundary disease risks.
- Poorly managed dumps or landfills on CAF → potential pathogen hotspots.
- Hence, CAF is both a biodiversity corridor and a public health corridor, requiring regional cooperation.
Conservation Challenges
- Vultures still absent in many regions despite partial recovery.
- Threats:
- Veterinary drugs (diclofenac, ketoprofen, nimesulide).
- Electrocution/collision with power lines.
- Fragmented funding and lack of integration with One Health strategies.
- Policy & health security efforts remain siloed.
Post-2025 Vulture Strategy – India’s Roadmap
Five proposed pillars:
- Nationwide Satellite Telemetry: Track habitats, migratory routes, and hotspots.
- Decision Support System (DSS): Integrate wildlife, livestock, and human health data.
- One Health Approach: Cross-sectoral coordination (health, environment, livestock).
- Transboundary Cooperation: Use CAF + align with WHO’s regional health security roadmap.
- Community Stewardship: Empower women, youth, local groups for awareness & surveillance.
India’s Global Opportunity
- India hosts key species: Himalayan griffon, Cinereous vulture, Eurasian griffon.
- Can showcase a “conservation = health security” model by:
- Scaling telemetry & DSS.
- Embedding vultures in One Health.
- Building pandemic resilience at modest cost compared to outbreak losses.
- Could inspire regional & global adoption of biodiversity-linked health security frameworks
