Carbon from stubble burning spreading to air in all parts of India: NASA scientist

NOIDA: It is high time to stop crop residue burning (CRB) which is practised within the states of Haryana, Uttar Pradesh and Punjab all through the post-harvest season, according to senior NASA scientist Sudipta Sarkar who, along with two different associates in the US and India, recently concluded a learn about on how CRB increases air pollution levels in the rest of the country.


The learn about, which was carried out earlier than, all through and after the CRB season, has printed that the air pollution brought about through this tradition has begun to turn far-reaching impact, spreading black carbon by way of prevailing wind to Maharashtra, Madhya Pradesh, Telangana, Chhattisgarh, Odisha and West Bengal. The Journal of Geophysical Research-Atmospheres printed the learn about through Sarkar, Ramesh P Singh of Chapman University, California, and Akshansha Chauhan, a PhD pupil from Sharda University, Greater Noida, on June 19. Crop residue burning spews black carbon and greenhouse gases into the atmosphere.


The follow was started in Punjab after the advent of mechanised harvesting in 2010. With this style of harvesting changing into an increasing number of fashionable in different states, the follow of CRB could also be on the rise. Sudipta Sarkar, senior scientist, NASA-Goddard Space Flight Centre, told TOI, “The scenario is urgent as a result of our statement presentations things may just go out of our arms if now not introduced below keep an eye on instantly. CRB is practised through those farmers who put in force mechanised harvesting which leaves a big a part of the crop’s stalk on the field. For lack of an alternate, the farmers burn the residue. If the farmers can promote this residue or are taught to transform it into manure, this risk would forestall. While we are told that motion has been taken to curb CRB, it is too early to signify if it has had any impact and we can follow the placement for a few extra years to state if it has progressed.”


The learn about used “energetic fireplace” data all through the post-monsoon season. The data was acquired with the assistance of NASA’s MODIS (Moderate Resolution Imaging Spectroradiometer) satellite. Sarkar said, “Some quantity of CRB takes position in central and southern states, as smartly, but it surely occurs most commonly within the previous months. The reason CRB in northwest India has such an adversarial impact is since the harvest season is after monsoon when the air is still humid and traps all pollutants. We saw a 40-60% jump in black carbon concentration over portions of central and southern India that in point of fact were given me hooked. This is occurring in November when you don’t see primary fireplace events in these portions of India. .”
