Rice growing and methane
Webb1 jan. 2024 · Although rice cultivation is one of the most important agricultural sources of methane (CH 4) and contributes ∼8% of total global anthropogenic emissions, large discrepancies remain among estimates of global CH 4 emissions from rice cultivation (ranging from 18 to 115 Tg CH 4 yr −1) due to a lack of observational constraints.The … WebbGrowing rice in flooded paddies produces methane, a greenhouse gas many times more powerful than carbon dioxide at warming our atmosphere. Since 2014, the International Rice Research Institute (IRRI) has implemented a Climate and Clean Air Coalition initiative to provide technical and policy guidance to governments to help reduce greenhouse gas …
