In the ongoing battle against air pollution in India, Richard Peltier, a senior US scientist and member of the World Health Organization’s Global Air Pollution and Health Technical Advisory Group, emphasized the importance of long-term strategies over quick-fix solutions. In an interview with PTI, Peltier expressed skepticism about the effectiveness of costly technologies like smog towers and cloud seeding in addressing the country’s pollution woes.
Understanding the Challenge
Peltier acknowledged the widespread recognition of India’s severe air pollution problem but highlighted the lack of precision in monitoring due to the limited distribution of air pollution monitors. Drawing parallels with the United States’ experience, he emphasized that achieving significant improvements in air quality is a gradual process that demands sustained effort and time.
Long-Term Efforts
Reflecting on the US’s journey in tackling air pollution through measures like the Clean Air Act implemented in the 1960s, Peltier emphasized the need for patience and persistence. He underscored that addressing India’s air pollution crisis is akin to a marathon rather than a sprint, requiring concerted efforts over several decades.
Limitations of Smog Towers
While smog towers have garnered attention as potential solutions, Peltier cautioned against over-reliance on these structures. While they may offer localized air purification benefits, their scalability to cover entire cities is questionable due to cost and maintenance challenges. Peltier likened the effectiveness of smog towers to “trying to dry up a big mighty river with a bath towel,” highlighting the impracticality of this approach.
Concerns with Cloud Seeding
Cloud seeding, another proposed solution, was also met with skepticism by Peltier. He raised doubts about its sustainability and long-term viability, questioning the practicality of continuously seeding clouds to induce rainfall. Peltier underscored the potential environmental impacts and logistical challenges associated with widespread cloud seeding operations.
Need for Enhanced Monitoring
Addressing concerns about the accuracy of pollution data due to limited monitoring infrastructure, Peltier stressed the importance of expanding the network of air pollution monitors, particularly in urban areas. While acknowledging the challenges, he emphasized the urgent need for more comprehensive monitoring to better understand and address air pollution hotspots.
Alarming Statistics
Highlighting the severity of India’s air pollution crisis, independent reports have underscored that a significant majority of the population breathes air exceeding WHO standards for PM2.5. Moreover, vulnerable groups like pregnant women are disproportionately affected, with a majority residing in highly polluted areas. The detrimental impact of air pollution on life expectancy, as revealed by research studies, further underscores the urgency of addressing this pressing issue.
In conclusion, Peltier’s insights emphasize the need for a multifaceted approach that prioritizes long-term strategies, enhanced monitoring, and sustainable solutions to combat India’s air pollution crisis effectively. As policymakers and stakeholders grapple with this complex challenge, a concerted effort guided by scientific expertise and international collaboration will be crucial in achieving meaningful progress towards cleaner air and healthier communities.
