According to a study conducted in India, rice farming across the world should be responsible for up to twice the level of climate impact relative to the climate impact which was previously estimated.

The study published in PNAS( Proceedings of the National Academy of Sciences) of USA found that intermittently flooded rice farms can emit 45 times more nitrous oxide as compared to the maximum from continously flooded farms that predominently emit methane.

The researchers investigated greenhouse gas emissions from rice farms across southern India. They found that nitrous oxide emissions from rice can contribute up to 99% of total climate impact of rice cultivation at a variety of intermittant flooded farms. These emissions contributed substantially to Global Warming pollution far more than the estimate of 10% previously suggested by multiple global rice research organizations.
