Slight improvement in Delhi’s air but situation still serious, stubble burning raises concern

Air Quality In Delhi -NCR: Delhi’s air quality improved marginally on Wednesday (November 3) due to relatively better conditions. The Air Quality Management Commission (CQM) said the restrictions under the fourth phase of the Graded Response Action Plan (GRAP) do not need to be implemented immediately. The restrictions under the fourth phase of GRAP include ban on entry of trucks and closure of educational institutions. SAFAR, an agency under the Union Ministry of Earth Sciences, said the share of stubble burning in Delhi’s 2.5 PM pollution rose to 32 per cent due to favorable transport-level wind speeds.

Transport-level winds blow in the lowest two layers of the atmosphere – the troposphere and the stratosphere – and bring smoke from farm stubble burning into the National Capital Region. Meteorological experts said moderately favorable surface-level wind speeds (up to 8 kmph) did not allow the pollutants to accumulate rapidly.

what was the condition of delhi

Delhi’s 24-hour air quality index (AQI) stood at 376, up from 424 on Tuesday, its worst since December 26 last year when it was 459. Addressing a press conference, Delhi Environment Minister Gopal Rai said that the impact of air pollution is not limited to the national capital and other National Capital Region (NCR) cities like Ghaziabad (AQI 332), Noida (339), Gurugram (NCR) The situation is equally bad in 310, Greater Noida (336) and Faridabad (346).

Targeting BJP

Aam Aadmi Party leader Rai said farmers in Punjab were forced to burn stubble as the BJP-led central government did not support the state government’s plan to give them cash incentives for not burning stubble.
