Recycling crop stubble is the simplest solution for Delhi’s annual smog problem

Hindustan Times  

Even as Delhi and the rest of India’s National Capital Region continues to be covered by thick smog, with Air Quality Index still in dangerous zones, we are yet to find a sustainable solution to this annual and largely man-made disaster. An estimated three-fourth of this are used as fodder for cattle and as fuel for a wide range of commercial and household needs and around 92 million tonnes of the crop waste is burned in-situ, making it one of the biggest contributors to the annual smog problem. A report by IIT Bombay estimated the economic cost of Delhi’s annual smog problem to be around $11 billion in 2015. The only solution that we can afford now is also the simplest and most effective one – cut and recycle the crop leftovers back into the soil, which is basically mulching. Burning crop kills every living organism, microbes to earthworm, up to one centimeter of soil, thus severally damaging it and making the crops that grow on them vulnerable to diseases.
