Why in the News?
The Central Pollution Control Board (CPCB) recorded an average AQI of 494 (Severe plus category) for Delhi where the different scales and methods explain the gap.
A study by the Centre for Science and Environment reveals that:

What are the challenges in Monitoring AQI?
- Inconsistent Data Reporting: There is confusion regarding AQI readings, with some private agencies reporting values exceeding 1,000 while official figures cap at 500. This discrepancy arises from differences in how pollutant concentrations are converted to AQI values based on less stringent national guidelines compared to WHO standards.
- Dependence on External Data: India’s reliance on satellite data from NASA for monitoring fires and pollution limits its ability to independently assess air quality. There is a need for more localized monitoring using Indian satellites that can provide continuous coverage.
- Lack of Comprehensive Frameworks: Current monitoring systems do not adequately account for regional cooperation or comprehensive frameworks that address transboundary pollution issues effectively. This lack of coordination complicates efforts to manage air quality across state lines.
Why does India need a sustainable and health-centric framework?
- Long-Term Strategies: Efforts must go beyond immediate fixes and focus on sustainable practices that consider the interconnectedness of air quality management and climate change adaptation. This includes integrating scientific research into policy-making and resource allocation.
- Public Health Prioritization: A health-centric approach should prioritize the well-being of citizens by implementing measures that reduce exposure to harmful pollutants, particularly for vulnerable populations such as children and the elderly.
- Multidisciplinary Solutions: Addressing air quality issues necessitates collaboration across various sectors, including transportation, urban planning, and public health. This multidisciplinary approach can foster innovative solutions tailored to local contexts while addressing broader climatic challenges.
Conclusion: Northern India’s AQI crisis highlights the urgent need for sustainable, health-centric air quality management. The government should address the pollution through multidisciplinary solutions aligned with SDG 3 (Good Health) and SDG 13 (Climate Action), ensuring healthier lives and climate-resilient communities for future generations.
Mains PYQ:
