Europe’s Nitrogen Problem
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.

Phosphorus demand for the 1970–2100 period: A scenario analysis of resource depletion
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.
Global river nutrient export: A scenario analysis of past and future trend
Synthesis of the Global Nutrient export from Watersheds project.
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 will continue to be a great challenge to China.
Human alteration of the global nitrogen and phosphorus soil balances for the period 1970–2050
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...
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 the future. This approach was developed as part of an international...
From forest to waste: assessment of the Brazilian soybean chain, using nitrogen as a marker
With economic growth, urbanization and changing diets, world demand for plant-derived oils and their derivates is soaring. Oils are used inter alia in the food, feed and cosmetics industry, and increasingly as a biofuel. Soybean is one of the major booming oil crops. In...
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, estuaries, continental shelves and oceanic waters, which has been described...
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 starting point, or baseline, was taken as the nitrate concentration of the...
The Dutch nitrogen cascade in the European perspective
This paper provides an overview of the origin and the fate of nitrogen in the Netherlands, the various reported impacts of nitrogen, the Dutch and European policies to reduce nitrogen emissions and impacts. In addition, ways are presented to go forward to potentially solve...
