Officials from the pollution control board have noted that the Graded Response Action Plan (Grap) period commenced on October 1. The Commission for Air Quality Management (CAQM) has directed various agencies to implement mitigation measures to combat air pollution, based on Delhi's air quality index (AQI).

According to GRAP, the adverse air quality is categorised into four different stages: stage 1 or 'poor' when the AQI ranges from 201-300, stage 2 or 'very poor' when AQI falls between 301-400, stage 3 or 'severe' when AQI ranges from 401-450, and stage 4 or 'severe+' when the AQI surpasses 450.

650 incidents of stubble burning reported so far

Punjab has reported over 650 instances of stubble burning as on Wednesday starting from September 15, news agency PTI reported citing data from the Punjab Remote Sensing Centre based in Ludhiana.

Specifically, on Wednesday, the state experienced 95 instances of stubble burning, a notable increase compared to 23 and 65 farm fires on the same day in 2021 and 2022, respectively.

The practice of burning paddy straw in Punjab and Haryana has been identified as a significant contributor to the concerning rise in air pollution levels in the Delhi-NCR region during October and November.

In response to this issue, the state's agriculture department has committed to providing 24,000 crop residue management machines to curb stubble burning. These machines include Super SMS, happy seeder, paddy straw chopper, mulcher, smart seeder, zero-till drill, surface seeder, super seeder, crop reaper, and shrub master for in-situ management, as well as baler and straw rake for ex-situ management of paddy residue.

With a budget of 350 crore, the agriculture department aims to eliminate stubble burning incidents in districts like Pathankot, Hoshiarpur, Rupnagar, Mohali, SBS Nagar, and Malerkotla.
