New Delhi: One-day contribution of stump burning to PM2.5 Delhi rose as high as 48%, but experts say the impact of agricultural fires is estimated to remain low now.
Data from air quality systems and weather forecasting and research (Safar) shows that combustion buncit shares have been below 10% since November 16, and only 3% on Tuesday.
A senior official, who wants to be named after, said, “Because the number of fires continues to fall, the impact on PM2.5 Delhi is likely to be ignored now.
Safar data shows that it remains below 10% in the last week of November 2020 too.” Fire count is 770 on Tuesday.
LS Kurinji, Partner Programs, Energy Councils, Environment and Water, said, “While agricultural fires usually subside around mid-November, this year observed a delay of 4-5 days (especially in Punjab) due to the delay for harvesting on a delayed Monsun withdrawal account.” Gufran beig , Director of the Founder Project, Safar, said, “Now, the period of the impact of burning stumps towards the impact session due to FAG and the fog will increase.” Safar data shows that the number of effective fire was 64,881 in November so far.
Safar calculates the number of effective fires of the four countries – Punjab, Haryana, Uttar Pradesh and Jharkhand.
Another analysis conducted by the Energy Council, Environment and Satellite Water NRT VIIRS 375M NASA, said that this year Punjab and Haryana (combined) reported a total of 86,004 agricultural fires, the highest since 2016.
However, the consortium for research on monitoring agroecosystems and modeling from outside laboratories Angkara, Indian Agricultural Research Institute (IArI), said a total of 89,162 burning events were detected in six countries between September 15 and November 23, 2021, which were distributed as 71,181; 6,792; 3,376; 4; 1,222 and 6,587 in Punjab, Haryana, UPS, Delhi, Rajasthan and MP, respectively.
Meanwhile, satellite data that differs from the number of fires varies depending on their methodology and resolution.
VK Sehagal, Professor and Main Scientist, IARI, said, “Data varies depending on special satellite resolutions.
It also depends on the channel used by the satellite to detect or estimate the surface temperature and also depend on the algorithm to detect the temperature difference in with respect to The surroundings.
“Kurinji added,” For the following season, priority must promote the absorption of short duration varieties and provide incentives to farmers to transition from rice.
