Projected Impact of Extreme Climatic Events on Animal Habitats by 2085

A 2024 study published in the Indian Express reports that extreme climatic events could affect 36% of terrestrial animal habitats globally by 2085. This projection is based on current trends in climate variability and habitat vulnerability, with India being a significant hotspot due to its diverse ecosystems. The Intergovernmental Panel on Climate Change (IPCC) AR6 data indicates a global temperature rise of 1.16C above pre-industrial levels as of 2023, exacerbating the frequency and intensity of extreme events such as heatwaves, droughts, and floods. The India Meteorological Department (IMD) confirms a 60% increase in extreme heatwave frequency between 2000 and 2020, directly threatening habitat stability for many species.

Legal and Constitutional Framework for Habitat Protection in India

Article 48A of the Constitution of India directs the State to protect and improve the environment, including animal habitats. The Environment Protection Act, 1986 (EPA 1986) empowers the central government under Sections 3 and 5 to take measures against environmental hazards, including those arising from extreme climatic events. The Wildlife Protection Act, 1972 provides habitat protection under Sections 2 (definitions) and 38 (protection of specified areas). The National Biodiversity Act, 2002 regulates biodiversity conservation through Sections 36 and 37, focusing on sustainable use and habitat preservation. The Forest Conservation Act, 1980 restricts forest land diversion under Sections 2 and 3, crucial for maintaining habitat connectivity. Landmark Supreme Court rulings such as M.C. Mehta v. Union of India (1987) have reinforced the judiciary's role in enforcing environmental safeguards.

Economic Consequences of Habitat Loss Due to Extreme Events

Climate-induced habitat degradation threatens not only biodiversity but also economic stability. The World Bank (2021) estimates global economic losses up to $1.2 trillion by 2050 due to habitat loss. India’s biodiversity-dependent sectors, including agriculture and tourism, contribute over 17% to GDP (Economic Survey 2023-24). The TERI Report (2022) values ecosystem services at approximately 61,500 billion annually, which are at risk from habitat disruption. The government's allocation of around 600 crore annually under the National Adaptation Fund for Climate Change (NAFCC) highlights efforts to build climate resilience, though current funding may be insufficient given the scale of projected impacts.

Institutional Roles in Monitoring and Mitigating Habitat Impacts

• Ministry of Environment, Forest and Climate Change (MoEFCC): Formulates policies and enforces laws related to environment and wildlife protection.
• India Meteorological Department (IMD): Provides early warning and data on extreme weather events.
• Zoological Survey of India (ZSI): Conducts research on animal biodiversity and habitat status.
• National Board for Wildlife (NBWL): Advises on wildlife conservation and habitat management.
• Intergovernmental Panel on Climate Change (IPCC): Offers scientific assessments on climate impacts globally.
• United Nations Environment Programme (UNEP): Supports international environmental governance and reporting.

Data on Habitat Vulnerability and Species at Risk

• 36% of terrestrial animal habitats projected to be impacted by extreme events by 2085 (Indian Express, 2024).
• India’s forest cover stands at 21.71% of total geographical area (Forest Survey of India, 2023).
• Over 70% of endangered species in India depend on specific habitats (ZSI Report, 2023).
• Climate change may reduce suitable habitats for Bengal tiger by 30% by 2050 (WWF India, 2023).
• Frequency of extreme heatwaves in India increased by 60% between 2000 and 2020 (IMD Report, 2022).

Comparative Analysis: India and Costa Rica on Climate Adaptation and Biodiversity Conservation

Critical Policy Gaps in India’s Climate and Biodiversity Framework

Current Indian policies inadequately integrate climate adaptation with biodiversity conservation, particularly regarding habitat connectivity and species migration corridors. This gap undermines resilience against extreme events, as fragmented habitats limit species' ability to relocate. Enforcement challenges under the Wildlife Protection Act, 1972 and delays in forest land diversion approvals under the Forest Conservation Act, 1980 further exacerbate habitat vulnerability. Additionally, economic incentives for local communities to participate in habitat conservation remain insufficient, reducing the effectiveness of existing schemes like NAFCC.

Significance and Way Forward

• Strengthen integration between climate adaptation and biodiversity conservation policies, emphasizing habitat connectivity and corridors.
• Increase funding and expand schemes like NAFCC to include targeted habitat restoration and species migration facilitation.
• Enhance enforcement of existing laws such as the Wildlife Protection Act and Forest Conservation Act to prevent habitat fragmentation.
• Adopt economic incentive models similar to Costa Rica’s PES to motivate local stakeholders in conservation efforts.
• Leverage institutional capacities of MoEFCC, IMD, ZSI, and NBWL for coordinated monitoring and rapid response to extreme events.
