    How much methane does rice produce in China?
    Methane emissions from rice cultivation in China are estimated at a range of 6.21–6.57 Tg yr −1 over the past two decades. Reduction in the rate of straw added could significantly lower methane emissions by 9.4 %–10 %. Policies focusing on production or demand can increase CH 4-rice by 0.3 % to 5.6 %.

  1. Rice cultivation and methane emission are linked as follows123:
    • Rice is a staple crop for more than half of the world’s people, but growing rice produces methane, a potent greenhouse gas.
    • Methane from rice contributes around 1.5 percent of total global greenhouse gas emissions.
    • As more carbon dioxide enters the atmosphere, rice plants grow faster, leading to increased methane production.
    • Rice fields harbor both methane-producing and methane-oxidizing microorganisms.

    Rice is the nutritious staple crop for more than half of the world’s people, but growing rice produces methane, a greenhouse gas more than 30 times as potent as carbon dioxide. Methane from rice contributes around 1.5 percent of total global greenhouse gas emissions, and could grow substantially.

    As more carbon dioxide enters the atmosphere, rice plants grow faster, the experimental data showed. This growth, in turn, pumps up the metabolism of methane-producing microscopic organisms that live in the soil beneath rice paddies. The end result: More methane.

    Does rice cultivation increase CH4 emissions?
    The trend of CH 4 emissions from rice cultivation showed an increase followed by no significant change and then, a stabilization over 1990–2020. Consequently, the contribution of CH 4 emissions from rice fields to the renewed increase in atmospheric CH 4 concentrations since 2007 was minor.
