Rice production systems are significant sources of anthropogenic emissions of the greenhouse gases (GHGs) i.e., methane (CH4) and nitrous oxide (N2O). Practicing alternate wetting and drying (AWD) in rice substantially affects rice yield as well as CH4 and N2O emissions from rice fields. However, it is difficult to determine global impacts from individual experiments as these studies differ in practice, experimental design, locations, nature of soil, and agro-ecological regions.

湿润和干燥交替保持水稻产量并降低全球变暖潜能值：一项全球荟萃分析


水稻生产系统是人为排放温室气体 （GHG） 的重要来源，即甲烷 （CH4） 和一氧化二氮 （N2O）。在水稻中实行交替湿润和干燥 （AWD） 会显着影响水稻产量以及稻田的 CH4 和 N2O 排放。然而，由于这些研究在实践中、实验设计、位置、土壤性质和农业生态区域方面有所不同，因此很难确定单个实验的全球影响。
