Nitrogen pollution costs the European Union between €70 billion and €320 billion per year. This cost is more than double the value that nitrogen fertilizers are estimated to add to European farm…
For the last five years, scientists across Europe have chronicled the little-known nitrogen dilemma and the threats it poses to our environment and health – as well as how we can solve the problem.
Increasing anthropogenic nitrogen inputs and riverine DIN exports from the Changjiang River basin
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…
Global nitrogen and phosphate in urban wastewater for the period 1970 to 2050
This paper constitutes the first spatially explicit, global assessment of sewage N and P emissions to surface water for the period 1970 to 2000, and the first projection of such N and P emissions for…
Global patterns of dissolved silica export to the coastal zone: Results from a spatially explicit global model
This study presents a model for river export of dissolved SiO 2 , with river-basin spatial scale and an annual temporal scale. The model is based on four variables with a significant influence on DSi…
A framework to identify appropriate spatial and temporal scales for modeling N flows from watersheds
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…
Denitritication across landscapes and waterscapes: a synthesis
Both newly fixed N and recycled N (e.g., manure) are processed by terrestrial ecosystems. A substantial portion of this recycled N is subsequently transferred to groundwater, wetlands, lakes, rivers…
Nitrate leaching in agriculture to upper groundwater in the sandy regions of the Netherlands during the 1992-1995 period
The Dutch National Monitoring Programme for Effectiveness of the Minerals Policy (LMM) was initiated to allow detection of a statutory reduction in nitrate leaching caused by a decreasing N load. The…
Environmental effects of manure policy options in the Netherlands
This study explores the effects of manure policy options for agricultural land in The Netherlands on nitrate leaching to groundwater, ammonia and nitrous oxide emissions to the atmosphere and on…
