What’s Causing The Pollution?

The main factors driving Delhi’s pollution include:

1. Vehicular Emissions: Contributing 16.4% of the pollution on Monday.
2. Stubble Burning: Responsible for 11% of the pollution on Sunday.
3. Weather Conditions: Stagnant winds and dropping temperatures trap pollutants near the ground, making the air quality worse.

Impact on Schools and Education: The Supreme Court has urged the Commission for Air Quality Management (CAQM) to consider resuming physical classes in schools. Moreover the court also gave a statement saying that students are missing out on mid-day meals and are unable to attend virtual classes.

In response, the CAQM has relaxed restrictions, allowing hybrid classes where students can choose to attend either in-person or online. This option will be available in Delhi and surrounding areas like Gurugram, Faridabad, Ghaziabad, and Noida.

Government Response and GRAP Stage 4: Delhi reached hazardous air quality levels on November 17, triggering the implementation of GRAP (Graded Response Action Plan) Stage-4, which includes measures like banning non-essential truck traffic. However, the Supreme Court criticized the Delhi government for not properly enforcing these measures.

Weather Forecast: Delhi’s weather on Monday was cooler than usual, with the temperature recorded at 25.8°C, which is slightly below the seasonal average. The India Meteorological Department (IMD) predicts moderate fog for Tuesday, with temperatures expected to range between 12°C and 26°C.

Conclusion: Delhi’s air quality continues to remain in the ‘very poor’ and ‘severe’ categories, with little improvement expected in the coming days. Efforts to manage the pollution are ongoing, but the weather conditions and high vehicular emissions are proving challenging. Meanwhile, the city is taking steps to adjust educational policies to ensure that students are not left behind.
