Why most measures taken to tackle pollution (in NCR) are episodic rather than strategic responses?
Published: October 26, 2018
Delhi is one of the most polluted cities in the world. To address this crisis there is a need of a strong policy support.
Measures taken to address the pollution crisis
- Regulating the use of firecrackers.
- Odd-even restrictions.
- SC ban on 2,000 cc+ diesel engines which was later lifted.
- Aiding mechanization of harvesting to prevent stubble burning.
- Mechanized sweeping and water-sprinkling of roads.
Why episodic responses not make much difference
- Odd-even didn’t make much impact because vehicles accounted for around 9% of the city’s pollution and just a tenth was due to 4-wheelers that were affected by odd-even restrictions.
- Road dust contributes 56% and 38% of Delhi’s PM10 and PM2.5 pollution; industries including power plants are responsible for over 50% of the NOx pollution.
- Crop stubble burning in Haryana and Punjab adds considerably to NCR.
- The sides of the roads could be paved or covered with grass that holds the soil together and stops the production of the dust
- Improving the efficiency and efficacy of public transport will aid in reducing the vehicular density on roads.
- Completing the peripheral highways around the capital to lower the movement of trucks into Delhi region.
- Improving the waste management practices so that the garbage dumps are not fired. There has to be a comprehensive solution for segregating and processing waste.
- The initiatives for mechanization for harvesting must be further expanded to reduce the stubble burning to zero.
Short-term solutions like green-crackers and community fireworks may help, but only as a few short gasps. There is a need of a comprehensive strategic policy to address the challenge of pollution.
