&lt;em&gt;Researchers from Harvard and NASA have shown that in October and November about half of all pollution in Delhi can be attributed to agricultural fires on some days&lt;br /&gt;
&lt;br /&gt;
Boston: &lt;/em&gt;Agricultural fires are to blame for about half of the pollution experienced in Delhi in October and November, a peak stubble burning season in Punjab, a Harvard study has found using satellite data from NASA.&lt;br /&gt;
&lt;br /&gt;
Many farmers in northwest India typically burn abundant crop residue on the fields after harvest season, to prepare their fields for subsequent planting. To what extent the large quantity of smoke emitted by these fires contributes to the already severe pollution in New Delhi has remained a key question.&lt;br /&gt;
&lt;br /&gt;
For the past few years, every autumn New Delhi&amp;mdash;already plagued with thick pollution&amp;mdash;gets engulfed choking smoke likened by many to a gas chamber. While crop burning has been illegal for years, there has not been a large enough deterrent to effectively crack down on the practice, in part because it&amp;rsquo;s been difficult to measure exactly how much smoke from the fires is making it downwind to the city.&lt;br /&gt;
&lt;br /&gt;
Researchers from the Harvard University and NASA have now shown that in October and November, a peak burning season in Punjab, about half of all pollution in Delhi can be attributed to agricultural fires on some days.&lt;br /&gt;
&lt;br /&gt;
&amp;ldquo;On certain days during peak fire season, air pollution in Delhi is about 20 times higher than the threshold for safe air as defined by the World Health Organization (WHO),&amp;rdquo; said Daniel H. Cusworth, a graduate student at SEAS.&lt;br /&gt;
&lt;br /&gt;
To model how much of that pollution is coming from the fires, the study published in the journal Environmental Research Letters, used satellite data from NASA to identify hotspots corresponding to active fires. &lt;br /&gt;

Boston: &lt;/em&gt;Agricultural fires are to blame for about half of the pollution experienced in Delhi in October and November, a peak stubble burning season in Punjab, a Harvard study has found using satellite data from NASA.&lt;br /&gt;

Many farmers in northwest India typically burn abundant crop residue on the fields after harvest season, to prepare their fields for subsequent planting.

Researchers from the Harvard University and NASA have now shown that in October and November, a peak burning season in Punjab, about half of all pollution in Delhi can be attributed to agricultural fires on some days.&lt;br /&gt;

Stubble burning doubles Delhi pollution: Harvard study

-PTI Researchers from Harvard and NASA have shown that in October and November about half of all pollution in Delhi can be attributed to agricultural fires on some days Boston: Agricultural fires are to blame for about half of the pollution experienced in Delhi in October and November, a peak stubble burning season in Punjab, a Harvard study has found using satellite data from NASA. Many farmers in northwest India typically burn abundant crop residue on the fields after harvest season, to prepare their fields for subsequent planting. To what extent the large quantity of smoke emitted by these fires contributes to the already severe pollution in New Delhi has remained a key question. For the past few years, every autumn New Delhi—already plagued with thick pollution—gets engulfed choking smoke likened by many to a gas chamber. While crop burning has been illegal for years, there has not been a large enough deterrent to effectively crack down on the practice, in part because it’s been difficult to measure exactly how much smoke from the fires is making it downwind to the city. Researchers from the Harvard University and NASA have now shown that in October and November, a peak burning season in Punjab, about half of all pollution in Delhi can be attributed to agricultural fires on some days. “On certain days during peak fire season, air pollution in Delhi is about 20 times higher than the threshold for safe air as defined by the World Health Organization (WHO),” said Daniel H. Cusworth, a graduate student at SEAS. To model how much of that pollution is coming from the fires, the study published in the journal Environmental Research Letters, used satellite data from NASA to identify hotspots corresponding to active fires.
