N2 - Returning organic nutrient sources (for example, straw and manure) torice fields is inevitable for coupling crop–livestock production. However,an accurate estimate of net carbon (C) emissions and strategies tomitigate the abundant methane (CH4) emission from rice fields suppliedwith organic sources remain unclear. Here, using machine learning and aglobal dataset, we scaled the field findings up to worldwide rice fields toreconcile rice yields and net C emissions. An optimal organic nitrogen (N)management was developed considering total N input, type of organicN source and organic N proportion. A combination of optimal organic Nmanagement with intermittent flooding achieved a 21% reduction in netglobal warming potential and a 9% rise in global rice production comparedwith the business-as-usual scenario. Our study provides a solution forrecycling organic N sources towards a more productive, carbon-neutral andsustainable rice–livestock production system on a global scale.
