Fig. 3: Spatial changes in various nitrogen loss from BAU to OPSR scenario.

Nitrous oxide (N2O) emissions in BAU (a) and OPSR (b), and change in N2O emissions from BAU to OPSR (c).Ammonia (NH3) emissions in BAU (d) and OPSR (e), and change in NH3 emissions from BAU to OPSR (f). Reactive nitrogen (Nr) loss to water in BAU (g) and OPSR (h), and change in Nr loss to water from BAU to OPSR (i). j The emission reduction potential of N2O, NH3, and Nr loss to water for different provinces. k The emission reduction potential of N2O, NH3, and Nr loss to water for different crops. BAU represents reference scenario reflecting current practices in fertilizer use and livestock distribution without any optimization. OPSR represents a scenario where manure is optimally substituted for synthetic nitrogen, and livestock is relocated to better match cropland nutrient needs. The error bars represent the standard deviation. The base map is applied from GADM data (https://gadm.org/).
