The Center-run Air Quality and Weather Forecasting System and Research (SAFAR) said that at present the deterioration of air quality is gradually causing adverse changes in weather conditions. In the Delhi environment on Friday (October 18), the participation of stubble burning in PM 2.5 concentrations increased to 10 percent. According to SAFAR’s data, on Saturday (October 12) it is projected to grow by 18 per cent.
The travel report states that there has been an increase in stray burns in Haryana, Punjab, western Uttar Pradesh and adjoining border areas for the last three days. The maximum incidents of stubble burning occur between October 15 and November 15 in Punjab and surrounding states. It is one of the major causes of air pollution in Delhi-NCR. Despite the ban on burning straw in Punjab and Haryana, farmers are doing so in the absence of financial incentives.
State governments are providing 50 to 80 percent subsidy to farmers and cooperatives to purchase modern agricultural equipment for proper management of straw and to conduct awareness campaign against burning of straw. The Delhi government has repeatedly emphasized that stubble burning was the main reason for Delhi’s deteriorating air quality. The Environmental Pollution (Prevention and Control) Authority appointed by the Supreme Court has said that pollution prevention and health of the local people is our FIR in Delhi.
Kuldeep Srivastava, a senior scientist of the India Meteorological Department, said that the winds are moving slowly in the east direction. This slow wind speed is not suitable for scattering of pollutants. There is an active Western Disturbance in parts of Jammu and Kashmir, Uttarakhand, Punjab and Haryana. The effect of stubble burning is expected to be slightly less here.
Srivastava said, “The wind speed is likely to increase after October 20 as a result of which the air quality of the city can be expected to improve.” The Meteorological Department officials said that the visibility level in Safdarjung and Palam areas fell from 2,30 meters at 5:30 pm to 1,500 meters at 8:30 pm due to haze due to pollution on Thursday (October 17).
