Sources: point (sewage) and diffuse (agriculture, natural areas)
Main inputs: agricultural activities, sewage systems, land use, hydrology
Main outputs: river export of DIN, DON, DOP, and DIP by source and sub-basin; ICEP (Indicator for Coastal Eutrophication Potential)
Modelling approach
Figure 1: Conceptual framework of the model application to China for global change impacts. SSP is shared Socio-Economic Pathways (Wang et al., 2020). SDG is sustainable development goal (Wang et al., 2022)
Model outputs (example)
Figure 2: Indicator for Coastal Eutrophication Potential for 2012 and 2050 scenarios (kg C-eq. km−2 day−1). SSP is Shared Socio-Economic Pathways. RCP is Representative concentrative Pathways. Published in Wang et al., (2020)
Figure 3: We found (a) Six SDGs that are highly relevant to nutrient pollution in Chinese water systems; (b) there are 319 interactions between SDG 6 “Clean Water and Sanitation”, 14 “Life Below Water” and other SDGs for the case of water pollution by nutrients in China.
