Heatwave Situation in India
India is experiencing unusually high temperatures early in the year, with the India Meteorological Department issuing heat alerts across central and southern regions.
Regions Affected
- Vidarbha
- Chhattisgarh
- Odisha
- Telangana
- Kerala
- Parts of Andhra Pradesh and Gujarat
- Tamil Nadu and Karnataka nearing 40°C
Contributing Factors
- Lack of western disturbances and thunderstorms
- Lower convective activity
- Residual effects of the previous El Niño
This unusual heat is typically observed in May-June but is now apparent in April, exacerbated by the urban heat island effect and humidity in coastal areas. Warmer nights hinder physiological recovery, increasing healthcare burdens.
Impacts and Concerns
- Higher risk of cardiovascular-related deaths
- Loss of 247 billion work-hours in 2024 due to heat
- Significant impact on workers in construction and agriculture
- Heat stress affecting farmers during the rabi harvest
- Accelerated crop maturity threatening food security and raising inflationary pressure
Criticism of Heat Action Plans (HAPs)
- Focus on emergency response rather than structural interventions
- Lack of funding for urban re-greening and heat-safety legislation
- Failure to address underlying vulnerabilities
Election Concerns
During the Tamil Nadu and West Bengal polls, and Gujarat and Maharashtra by-elections, high temperatures posed challenges. The Election Commission extended polling booth hours to mitigate heat impact, but such measures are insufficient.
Recommendations for Future Action
- Increase funding for HAPs and public systems
- Implement mobile health units and doorstep delivery of essential services
To combat ongoing climate challenges, India is encouraged to join a coalition of around 50 countries, organized by Colombia, to transition away from fossil fuels for better access to climate adaptation finance.
