China has been developing fast over the last decades. Intensive human activities in food production and urbanization have led to increasing nitrogen (N) and phosphorus (P) losses to water systems, causing freshwater and coastal water pollution. Reducing water pollution is important in China, especially given its commitments to the Sustainable Development Goals (SDGs) (e.g., SDGs 6 - "clean water and sanitation" and 14 - "life below water"). Nutrient models have been used to analyze the causes of nutrient pollution in water systems and to explore solutions for China. Existing modeling studies focus on either nutrient flows in human activities (e.g., food production) at administrative (e.g., province, country) scales, or on nutrient fluxes from land to water systems at biogeophysical scales (e.g., river basins). However, a better understanding of how human activities at the administrative scales affect nutrient fluxes at bio-geophysical scales of water systems is needed for China. Nutrient pollution in water systems may continue to increase in the future because of the expected changes in socio-economic development (e.g., population, economy) in China. Climate change may also influence hydrology (e.g., runoff, river discharges), and thus will influence nutrient transport in water systems (e.g., rivers). However, how socio-economic and climatic changes, together, will affect future nutrient pollution in water systems in China is not well studied. Such analysis can be done by implementing the global Shared Socio-economic Pathways (SSPs) and Representative Concentration Pathways (RCPs) in nutrient models for China. Moreover, many policies in China attempt to reduce future water pollution by nutrients. However, limited insights are available on the effectiveness of these policies for reducing future water pollution by nutrients. The objective of this PhD thesis is thus to improve our understanding of nutrient pollution in water systems in China, with a focus on the challenges, trends, and solutions. To this end, I formulated six sub-objectives for my research on nutrient pollution in water systems (sub-objectives 2, 4, and 6) from human activities on land (sub-objectives 1, 3, and 5).
