The phosphorus (P) cycle has been significantly altered by human activities. For this paper, we explored the sustainability of current P flows in terms of resource depletion and the ultimate fate of these flows.
Our result indicates that anthropogenically enhanced N inputs dominate and will continue to dominate river DIN yields under changing human pressures in the basin. Therefore, nitrogen pollution is and will continue to be a great challenge to China.
The Millennium Ecosystem Assessment (MEA) scenarios allow for describing contrasting future developments in agricultural nutrient use under changing climate for the next five decades. Massive increases in the flows of N and P are expected in all scenarios in the developing...
Many different large-scalewatershed nitrogen (N) flowmodels exist, which describe processes related to the horizontal movement of N through large drainage networks of river basins. Equations of such models can be applied on different scales. This modeling scale is important...
