NASA Research Reveals Shift in Stubble Burning Timing Worsens North India's Air Pollution Crisis
Dec 16, 2025 05:44 pm CST
NASA scientists have identified a significant shift in stubble burning patterns across northern India, with farmers now setting fires later in the evening rather than afternoon. This timing change complicates pollution monitoring efforts and may worsen air quality as evening conditions allow pollutants to accumulate more efficiently overnight. Satellite data shows this pattern shifting from 1-2 PM to 4-6 PM burning times, contributing to hazardous air quality levels across the Indo-Gangetic Plain during post-harvest seasons.
Satellite Data Reveals Farmers Shifted Stubble Burning to Afternoons, Evading Detection Systems
Dec 09, 2025 08:17 pm CST
New satellite analysis challenges claims of 90% reduction in stubble burning across Punjab and Haryana, revealing farmers have strategically shifted burning times to afternoons to evade monitoring systems. While burnt area has genuinely decreased by 25-37%, significant burning continues, undermining Delhi's air quality policy efforts.
Delhi's Air Quality Reaches 7-Year High: AQI Drops to 291 as Anti-Pollution Measures Show Results
Nov 05, 2025 01:16 am CST
Delhi has achieved its best air quality in seven years with an AQI of 291, significantly improved from 381 in 2024 and 415 in 2023. Environment Minister Manjinder Singh Sirsa credits this improvement to year-round pollution control efforts, including intensified monitoring of construction sites, vehicular emissions, and waste burning. While challenges from crop burning and increasing vehicles remain, the coordinated approach is delivering measurable results for Delhi's air quality.
Delhi Air Quality Crisis: 5 Monitoring Stations Record 'Very Poor' AQI Exceeding 300
Oct 15, 2025 06:48 pm CST
Delhi's air quality has deteriorated significantly with five monitoring stations recording 'very poor' AQI levels above 300. Anand Vihar topped the list at 345, while 20 other stations reported 'poor' air quality. Transport emissions remain the biggest pollution contributor at 19.8% as the city continues to struggle with worsening air conditions despite below-normal temperatures.
