Agricultural Phosphorus Inputs to Rivers Under Climate and Management Scenarios

Agricultural dissolved inorganic phosphorus inputs to rivers are modeled from 2000 to 2099 under three phosphorus management storylines and two climate scenarios. The dataset includes spatially explicit thresholds for DIP inputs based on Chinese surface water quality standards. It was created by Xuanjing Chen and published in 2026.

Use Cases

• Compare projected agricultural DIP inputs under constant P surplus (S1), linearly decreasing surplus (S2), and no surplus scenarios.
• Assess environmental risk by evaluating DIP inputs against proposed spatially explicit clean-water thresholds.
• Analyze the interaction between climate scenarios (RCP 2.6 and RCP 8.5) and P management on future river pollution.
• Model legacy phosphorus effects by examining DIP inputs from 2000-2019 as a baseline for 2020-2099 projections.

Strengths

• Projections span a 100-year period from 2000 to 2099.
• Includes three distinct P management storylines and two climate scenarios for comparison.
• Data is licensed under CC-BY-4.0 for open reuse.

Limitations

• Dataset size is 113.9 KB, indicating limited raw data or a summary of model outputs.
• Spatial coverage is unclear beyond a reference to the Yangtze River Channel.
• Model outputs depend on the assumptions of the underlying storylines and climate models.
