sends plumes of acrid smoke packed with dangerous cancer-causing particles drifting over a densely-populated belt of northern India, including capital New Delhi's 30 million people.</p> <p>But it is cheap—for farmers at least—to carry out.</p> <p>Small-scale growers like Sher with less than two hectares (five acres) of land—who make up 86 percent of Indian farms, according to the World Economic Forum—say alternatives to burning simply do not allow them to make the profit they need to survive.</p> <p>The 55-year-old farmer is just one of the many thousands who torch the stubble left after their rice harvest to prepare the fields to plant a winter crop of wheat.</p> <p>"I am scared of the authorities finding out, but I can't help it," said Sher, from Haryana's Jind district, as black plumes rose from his fields some 115 kilometers (70 miles) from the capital.</p> <p>He faces a hefty fine and loss of critical government farming subsidies if caught.</p> <p>But he said that burning provided the only way to clear the land in time to ensure wheat seeds are planted in the narrow weather window.</p> <div class="article-gallery lightGallery"> <div

part of the toxic smog impacting the health of millions, which, along with vehicle and factory emissions, create choking air that surges to more than 50 times the World Health Organization recommended limit of hazardous PM2.5 pollutants.</p> <p>A study in <i>The Lancet</i> medical journal attributed 1.67 million premature deaths in India to air pollution in 2019.</p> <p>India's federal government has pumped in millions of dollars of subsidies to encourage modern machinery to stop the burning.</p> <p>That includes baling machines that gather the straw into blocks, as well as combined plowing and planting tools, which return the stubble back into the soil while sowing the next crop.</p> <div class="article-gallery lightGallery"> <div

</div> </div> <p>It makes economic sense on paper for the longterm, but the wider cost of burning is vast.</p> <p>One study by global consultancy firm Dalberg estimates air pollution overall drives losses to the tune of $95 billion annually, or roughly three percent of the country's GDP.</p> <p>Burning fields also "reduces <a href="https://phys.org/tags/water+retention/" rel="tag" class="textTag">water retention</a> and <a href="https://phys.org/tags/soil+fertility/" rel="tag" class="textTag">soil fertility</a> by 25 to 30 percent", according to the UN Environment Program, thus requiring farmers to pay more in expensive fertilizers and irrigation systems.</p> <p>But <a href="https://phys.org/tags/small-scale+farmers/" rel="tag" class="textTag">small-scale farmers</a> say the numbers do not add up for them.</p> <p>They cannot afford to buy the tractors needed, so they must rely on costly contractors to clear their fields.</p> <p>Rice and wheat farmer Ajay Saini said that slices into his already limited profits.</p> <p>"We spend money from our pockets in paying the contractor," he said, adding that the straw bales collected had tumbled in value too.</p> <div
