G_B_ Posted November 19 Share Posted November 19 https://www.business-standard.com/india-news/punjab-farm-fires-peak-as-sc-blasts-authorities-over-pollution-crisis-124111900246_1.html Farm fire surge defies earlier trends Nasa’s satellite data, collected between noon and 1:30 pm, showed a sharp rise in farm fires compared to recent years. Hiren Jethva, an aerosol remote sensing scientist at Nasa Goddard Space Flight Center, revealed a concerning shift in the timing of stubble burning. “Fires are increasingly being lit after 2 pm, beyond the time when the Nasa satellite passes over India. This raises questions about whether farmers are deliberately trying to evade detection,” Jethva told NDTV. Deeply concerning. How does this compare to Up and Haryana? I hope the AAP gov is not avtively turning a blind eye to this new tactic. diga 1 Link to comment Share on other sites More sharing options...
coffee_rules Posted November 19 Share Posted November 19 I heard that the actual fires were even higher, They wait out the time the NASA satellites pass the area and start the burning after 5 pm. You don’t have to teach jugaad to Indians! Link to comment Share on other sites More sharing options...
rkt.india Posted November 20 Share Posted November 20 Rice stubble is used as bhoosa food for cattle so why don't Punjabis sell that to bhoosa sellers! Link to comment Share on other sites More sharing options...

mishra Posted November 20 Share Posted November 20 Interestingly looks like clouds of dust start in Pakistan and moves towards India via Punjab. Reaches Delhi and then towards UP but subides in UP. so seems like Pakistanis are also contributing to our misery Lone Wolf, jigjig, Lord and 1 other 4 Link to comment Share on other sites More sharing options...

G_B_ Posted November 21 Author Share Posted November 21 is stuble burning an issue in Pakistan as well? Farmers need other crops than basmati. I doubt India gains mush financially from basmati? Link to comment Share on other sites More sharing options...

Many farmers, particularly in the Punjab region, use fire as a fast, inexpensive way to clean up fields before planting winter wheat crops. However, the influx of smoke to the densely populated Indo-Gangetic Plain often contributes to a sharp deterioration of air quality in October and November. Levels of air pollution soared during the last week of October and first week of November in 2024 as weather patterns kept air bottled up in the Indo-Gangetic Plain. On November 3, 2024, the VIIRS (Visible Infrared Imaging Radiometer Suite) on the Suomi NPP satellite acquired this natural-color image of plumes of smoke streaming from large numbers of small fires burning in Pakistan and India. Air quality sensors in Lahore, Pakistan, recorded concentrations of fine particulate matter (PM2.5) at hazardous levels—above 300 on the air quality index (AQI)—on several days in October and November, according to data posted by AirNow. As pollution levels rose, authorities in Pakistan announced school closures, partial lockdowns, and halts in construction in a bid to limit the health impacts, according to news reports. Smoke from crop fires is not the only contributor to the hazy skies, explained Pawan Gupta, a lead scientist for AERONET, a NASA-sponsored network of ground-based sensors that measures the concentration of aerosols at hundreds of locations around the world. Influxes of dust sometimes arrive from the Thar Desert to the west. An array of other human-caused sources of air pollution in cities, including motor vehicle emissions, industrial and construction activity, fireworks, and fires for heating and cooking, also produce particulate matter and other pollutants, Gupta added. Geography and weather can exacerbate the region’s poor air quality. Temperature inversions are common in November and December as cold air rolls off the Tibetan Plateau and mixes with smoky air from the Indo-Gangetic Plain. An inversion can function like a lid, with warm air trapping pollutants near the surface. The low-hanging haze becomes hemmed in between the Himalayas to the north and the Vindhya Range to the south. @Lord Seems it all starts in Pakistan and becomes more concentarted in Punjab Delhi and Haryana Edited November 21 by mishra coffee_rules and Lord 1 1 Link to comment Share on other sites More sharing options...

I doubt India gains mush financially from basmati? Throwing baby out with the bathwater. There are many alternative ways to handle this. It has been discussed widely on this board on 2 other threads. Farmers and govt must work together to incentivize and implement. Link to comment Share on other sites More sharing options...

Can we NOt ask Farmers to keep their stubble for some time and wait for Easterly wind and then burn it. I know this is not permanent Fix but would temporarily fix the issue and be a lesson to Pakistanis taht Wind blows both directions Edited November 21 by mishra Link to comment Share on other sites More sharing options...
