Climate change has emerged as a public health emergency globally and in India, driven by rising temperatures, extreme weather events, and ecological disruptions. Between 2000 and 2020, heat-related mortality in India increased by 53%, while air pollution exacerbated by climate change causes approximately 1.67 million premature deaths annually (Lancet Countdown 2023; State of Global Air Report 2023). These dynamics strain health systems and disproportionately affect vulnerable populations such as children under five and urban slum dwellers, necessitating integrated policy responses across environmental and health governance frameworks.

Constitutional and Legal Framework Addressing Climate-Health Nexus
Article 21 of the Constitution, interpreted by the Supreme Court in Subhash Kumar v. State of Bihar (1991), includes the right to a healthy environment, establishing a constitutional basis for climate-related health protections. The Environment Protection Act, 1986 empowers the central government under Sections 3 and 5 to take necessary measures for environmental protection, indirectly safeguarding public health.
- National Disaster Management Act, 2005: Sections 6 and 11 mandate preparedness and response for disasters, including climate-induced health emergencies such as heatwaves and floods.
- Epidemic Diseases Act, 1897: Provides legal mechanisms to control disease outbreaks exacerbated by climate change, such as vector-borne diseases.
- National Health Policy 2017: Emphasizes development of climate-resilient health systems and integration of climate risks into health planning.
Economic Burden of Climate-Related Health Impacts in India
India’s health expenditure is approximately 2.5% of GDP (Economic Survey 2023-24), but climate change is projected to increase health costs by $4.5 billion annually by 2030 (WHO, 2018). Heatwaves have caused productivity losses estimated at 2.5% of GDP in vulnerable states (NITI Aayog, 2022), while vector-borne diseases linked to climate change may increase by 30% by 2050 (Lancet Countdown, 2023).
- National Adaptation Fund for Climate Change (NAFCC): Has a corpus of ₹350 crore for climate resilience projects, including health infrastructure upgrades.
- Climate-induced health costs include increased hospitalizations, lost labor productivity, and expanded disease surveillance needs.
- Economic losses disproportionately affect low-income and marginalized communities, exacerbating health inequities.
Institutional Roles in Managing Climate-Health Emergencies
Multiple institutions share responsibilities for climate-health governance in India, often operating in silos. The Ministry of Environment, Forest and Climate Change (MoEFCC) formulates climate policies, while the Ministry of Health and Family Welfare (MoHFW) integrates climate impacts into public health planning.
- Indian Council of Medical Research (ICMR): Conducts research on climate-sensitive diseases such as dengue and malaria.
- National Centre for Disease Control (NCDC): Monitors outbreaks of climate-sensitive epidemics and supports early warning systems.
- Central Pollution Control Board (CPCB): Tracks environmental pollutants that worsen health outcomes.
- National Disaster Management Authority (NDMA): Coordinates disaster response including climate-related health emergencies.

Comparative Analysis: India vs Bangladesh on Climate-Health Policy Integration
Bangladesh’s Climate Change Strategy and Action Plan (2021) integrates health adaptation through community-based early warning systems and mobile health clinics, achieving a 20% reduction in heat-related mortality over five years. India’s approach remains fragmented, with limited coordination between environment and health ministries and insufficient focus on vulnerable populations.
| Aspect | Bangladesh | India |
|---|---|---|
| Policy Integration | Unified climate-health strategy | Siloed environment and health policies |
| Community Engagement | Early warning systems, mobile clinics | Limited community-based health adaptation |
| Focus on Vulnerable Groups | Explicit targeting of marginalized populations | Insufficient focus on urban poor and tribal groups |
| Outcome | 20% reduction in heat mortality (5 years) | Rising heat-related mortality and disease burden |
Critical Gaps in India’s Climate-Health Response
- Lack of a unified climate-health framework leads to fragmented interventions and inefficient resource use.
- Data integration between environmental monitoring and health surveillance remains inadequate.
- Vulnerable populations such as urban slum dwellers, children, and tribal communities receive insufficient targeted interventions.
- Limited capacity at state and local levels to implement climate-resilient health infrastructure and emergency preparedness.
Way Forward: Strengthening Climate-Health Governance
- Develop a comprehensive national climate-health action plan integrating MoEFCC and MoHFW mandates.
- Enhance data sharing platforms linking environmental and health surveillance for early warning and response.
- Expand targeted interventions for vulnerable groups, including urban poor and tribal populations, with community participation.
- Increase budgetary allocation for climate-resilient health infrastructure under NAFCC and National Health Policy provisions.
- Strengthen capacity building at state and district levels for climate-health emergency preparedness and response.
- The Environment Protection Act, 1986 empowers the central government to take measures for environmental protection impacting health.
- The Epidemic Diseases Act, 1897 specifically addresses climate change-related health emergencies.
- The National Disaster Management Act, 2005 mandates preparedness for climate-induced health emergencies.

FAQs
How does Article 21 of the Indian Constitution relate to climate change and public health?
Article 21 guarantees the right to life, which the Supreme Court has interpreted to include the right to a healthy environment (Subhash Kumar v. State of Bihar, 1991). This interpretation provides a constitutional basis for addressing climate change as a threat to public health.
What are the key climate-sensitive diseases exacerbated by climate change in India?
Vector-borne diseases such as dengue, malaria, and chikungunya have expanded their geographic range by 15% due to rising temperatures (ICMR, 2022). Heat-related illnesses and respiratory diseases linked to air pollution are also increasing.
What role does the National Disaster Management Authority (NDMA) play in climate-health emergencies?
NDMA coordinates disaster preparedness and response, including for climate-induced health emergencies like heatwaves and floods, as mandated by Sections 6 and 11 of the National Disaster Management Act, 2005.
Why is India’s climate-health response considered fragmented?
India lacks a unified climate-health framework, resulting in siloed interventions between environment and health ministries, poor data integration, and inadequate focus on vulnerable groups such as urban poor and tribal populations.
How has Bangladesh’s approach to climate-health adaptation differed from India’s?
Bangladesh’s Climate Change Strategy and Action Plan (2021) integrates health adaptation through community-based early warning systems and mobile clinics, achieving a 20% reduction in heat-related mortality over five years, contrasting with India’s fragmented policy landscape.
