The architect of the country’s green revolution, M.S. Swaminathan, on Tuesday gave a clarion call for taking up an ‘evergreen revolution’ that “increases productivity in perpetuity without causing any ecological harm and without using chemical inputs”.

“I am against a second green revolution, but I am very much for an evergreen revolution,” he said. Pointing out that a majority of food production comes from farmers with small holdings, he said it was essential to increase their income through higher productivity. But it should be done without harming ecological interests, he noted.
