Farm stubble fires of Punjab-Haryana-Delhi have increased in numbers, intensity: Centre for Science and Environment
The Centre for Science and Environment (CSE) has issued an early winter pollution alert and stated that farm stubble fires of Punjab-Haryana-Delhi have increased in numbers and intensity. Delhi’s seasonal winter PM2.5 average improved during the pandemic, but it stagnated post-pandemic. As Delhi and the National Capital Region (NCR) brace for the upcoming winter, it remains to be seen if the seasonal average of PM2.5 during winter -- that had improved during the pandemic but had stagnated post-pandemic -- will further bend or increase. This winter season is also starting from a much cleaner benchmark due to rains in September and October. The Centre for Science and Environment’s (CSE) Urban Lab has released its winter pollution assessment – the objective, says Anumita Roychowdhury, executive director, research and advocacy, CSE, has been “to understand the trend and the starting line of the onset of the winter pollution season or pre-winter levels in this region. Farm stubble fires of Punjab-Haryana-Delhi are increasing both in numbers and intensity. Last year registered the highest instances of farm stubble fire in the last seven years -- 2021 October-November saw a 10 per cent jump in observed fire count by MODIS and 5 per cent increase by VIIRS compared to 2020 October-November. Similarly, the total fire radiative power from these fires was 13 per cent and 7 per cent higher compared to the 2020 fires as observed by MODIS and VIIRS respectively.
