Delhi’s persistent air pollution crisis continues to raise concerns despite the implementation of several mitigation measures, including smog towers and anti-smog guns. Experts argue that these short-term solutions have failed to bring about significant improvements in air quality, emphasizing the need for comprehensive regional policies and stronger political commitment.
Ineffectiveness of Current Measures
Delhi authorities have introduced various initiatives over the years to combat air pollution, including:
- Smog Towers: Installed in high-traffic areas to purify the air within a limited radius.
- Anti-Smog Guns: Used to spray water in the air to reduce dust and particulate matter.
- Odd-Even Vehicle Scheme: Implemented periodically to control vehicular emissions.
- Construction Bans: Temporary halts on construction activities during peak pollution seasons.
Despite these efforts, Delhi’s Air Quality Index (AQI) frequently remains in the ‘Severe’ category, with PM2.5 and PM10 levels far exceeding safe limits recommended by the World Health Organization (WHO).
Expert Opinions and Recommendations
Environmental experts and health specialists have expressed concerns over the limited impact of current pollution control measures. Some key observations include:
- Localized Solutions Not Enough: Experts believe that smog towers and water sprinklers only provide temporary relief in isolated areas and fail to address pollution at the source.
- Regional Cooperation Needed: Pollution in Delhi-NCR is largely influenced by emissions from neighboring states, including industrial activities, vehicular pollution, and stubble burning.
- Need for Policy Overhaul: Stricter enforcement of emission norms, promotion of clean energy alternatives, and investment in public transport infrastructure are recommended as long-term strategies.
According to Dr. Anumita Roychowdhury, an environmentalist at the Centre for Science and Environment (CSE), “Air pollution control requires a multi-pronged approach, including regional collaboration, sustainable urban planning, and aggressive promotion of electric mobility.”
Government’s Response and Future Plans
In response to growing criticism, Delhi authorities have announced plans to:
- Expand electric bus fleets to reduce reliance on fossil fuels.
- Introduce stricter emissions checks for industries and vehicles.
- Encourage afforestation and green infrastructure projects.
The Delhi government has also urged neighboring states to work collaboratively on measures such as crop residue management to reduce seasonal pollution spikes.
Key Takeaways
- Short-term measures like smog towers and water sprinklers offer limited relief.
- Experts advocate for regional cooperation and long-term policies to address pollution at the source.
- Government plans to focus on electric mobility and stricter emission norms in the future.
Conclusion
While Delhi continues to battle severe air pollution, experts agree that a holistic, multi-sectoral approach is the only way forward. Stronger policies, better enforcement, and regional cooperation are crucial to achieving sustainable air quality improvements for the capital and its surrounding areas.
