Context
Recent studies highlight that while chemical threats like diclofenac previously devastated India's vulture populations, electrocution from expanding power infrastructure is emerging as a critical new threat. The decline of vultures has far-reaching consequences, including increased human mortality and economic costs due to a rise in feral dog populations and rabies outbreaks.
UPSC Perspectives
Environmental
The near-extinction of India's vultures in the 1990s, driven by the veterinary use of and other Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) like aceclofenac and ketoprofen, demonstrates a catastrophic failure in biodiversity conservation. Vultures act as keystone species and crucial scavengers; their absence disrupts the ecosystem's energy flow and nutrient cycling by leaving carcasses to rot. The new threat of electrocution exacerbates this crisis. Vultures' large wingspans and behavior—perching on elevated structures and congregating near food sources—make them highly vulnerable to power lines. The reported 50% decline in nesting at historic sites underscores the urgency of addressing this infrastructure-wildlife conflict. Mitigation strategies, such as relocating carcass dumps away from power lines, insulating conductors, and installing safe perches, are vital interventions. UPSC questions often focus on the ecological roles of specific species and the drivers of their decline, making the shift from chemical to structural threats a key analytical point.
Social
The ecological collapse of vulture populations has severe public health and economic repercussions, illustrating the interconnectedness of human well-being and ecosystem health—a core concept in One Health. The disappearance of vultures led to an accumulation of livestock carcasses, which fueled a population explosion of feral dogs. This, in turn, precipitated a significant increase in rabies outbreaks. A 2024 study cited in the estimated a 4% rise in human mortality and staggering economic damages costing India $69.4 billion annually. This scenario highlights how environmental degradation translates into a public health crisis and economic burden. From a governance perspective, the initial ban on and subsequent bans on other harmful NSAIDs in 2023 represent reactive policy measures. The current challenge demands proactive infrastructure planning to mitigate electrocution risks, emphasizing the need for inter-departmental coordination between wildlife conservation authorities and power sectors.
Governance
The management of the vulture crisis reveals complexities in environmental governance and regulatory enforcement in India. The initial ban on for veterinary use by the was a necessary step, but the continued threat from other NSAIDs necessitated further regulatory action in 2023. The emerging issue of electrocution requires a different regulatory approach, focusing on infrastructure standards and environmental impact assessments (EIA) for power projects. The mitigation measures suggested, such as retrofitting power lines and altering waste disposal practices, require significant investment and strict compliance monitoring by bodies like the and state forest departments. The under-documentation of avian electrocution points to a gap in data collection and monitoring, which is crucial for evidence-based policymaking. UPSC Mains questions could explore the efficacy of regulatory bans versus structural mitigation strategies in wildlife conservation, using the vulture crisis as a prime case study.
