a total dissolved N (TDN) inputs to rivers, b total dissolved P (TDP) inputs to rivers, c river export of TDN to seas, and d river export of TDP to seas. These rivers are the Liao, Hai, Yellow, Huai, Yangtze, and Pearl Rivers. For 2050, six scenarios are explored: baseline SSP5-RCP8.5 (Shared Socio-economic Pathway 5-Representative Concentration Pathway 8.5), and alternative SE (improved sewage treatment), AG (improved nutrient use efficiencies in agriculture), AG + SE (a combination of AG and SE), AG + SE + SFC (sustainable food consumption in addition to AG + SE), and AG + SE + SFC + CLI (climate mitigation in addition to AG + SE + SFC) scenarios. Others include biological N2 fixation, atmospheric N deposition, and leaching of organic matter for TDN, as well as P weathering and leaching of organic matter for TDP.
