A new method of cultivation, called direct seeded rice (DSR), reduces the overall cost of cultivation by using 12-35% less irrigation water and reducing labor, sowing time, and use of chemical herbicides and fertilisers. The cultivation of rice, a staple food for more than 3 billion people worldwide, is responsible for 12% of global methane emissions and 1.5% of total greenhouse gas emissions.
Agriculture is India s biggest employer, supporting the livelihoods of 250 million farmers and informal labourers - but their work is getting harder as climate change makes living off farming difficult, pushing up debt, migration and suicides. Worries over falling yields have driven up the use of chemical fertilisers that are stripping the soil of nutrients and fuelling agricultural emissions on a warming planet.
