Given the concerns around climate change and ecological degradation, a shift to natural farming practices that exclude the use of chemical fertilizers and pesticides, is advocated by many as the only way forward. But, can going back to a simplistic method of using farm waste and manure help feed a country of 1.4 billion? Is natural farming even financially sustainable for farmers and consumers alike? And in any case, there is very little evidence so far about the efficacy of natural farming. A new report by the Bengaluru-based NGO The Nudge, tries to offer some. The Plate's editor TR Vivek speaks to Ankur Sanghai, an associate director at The Nudge and the lead author of the report to understand if the idea of a shift to natural farming is utopian or indeed an urgent need to save the planet.
