Losses of Ammonia and Nitrate from Agriculture and Their Effect on Nitrogen Recovery in the European Union and the United States between 1900 and 2050

Historical trends and levels of nitrogen (N) budgets and emissions to air and water in the European Union and the United States are markedly different. Agro-environmental policy approaches also differ…

Costs and effectiveness of on-farm measures to reduce aquatic risks from pesticides in the Netherlands

The European Union requires growers to implement the principles of integrated pest management (IPM) by 2014. This paper provides a quantitative overview of the costs and effectiveness of voluntary IPM…

Mariculture: significant and expanding cause of coastal nutrient enrichment

Mariculture (marine aquaculture) generates nutrient waste either through the excretion by the reared organisms, or through direct enrichment by, or remineralization of, externally applied feed inputs…

Hindcasts and Future Projections of Global Inland and Coastal Nitrogen and Phosphorus Loads Due to Finfish Aquaculture

A global model is used to calculate feed and nutrient budgets for freshwater and marine omnivorous and carnivorous aquacultural finfish production. The model uses national production data for the…

Management, regulation and environmental impacts of nitrogen fertilization in north-western Europe under the Nitrates Directive; a benchmark study

Implementation of the EU Nitrates Directive and its environmental impacts were compared for Member States in the north-west of the European Union (Ireland, United Kingdom, Denmark, the Netherlands…

Evaluation of the Dutch policy document on sustainable crop protection

Water quality has improved due to legislation on crop protection. However, policy objectives for ecological quality of surface waters and drinking water, as set in the Dutch policy document on…

Nitrogen: 'Too much of a good thing'

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…

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.

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…
