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 period 1970–2010 and the Millennium Ecosystem Assessment scenarios for...
Cost-benefit analysis can be used to provide guidance for emerging policy priorities in reducing nitrogen (N) pollution. The results support the priority for further reduction in NH3 and NOx emissions from transport and agriculture beyond commitments recently agreed in...
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, Belgium, northern France and Germany). The most marked effect since the...
This paper presents a spatially explicit model for simulating the transport of nitrogen (N) and the denitrification and associated production of nitrous oxide (N2O) in groundwater, with a one-kilometre resolution on the European scale. The model shows that the projected...
Global nutrient surpluses will continue to increase in the next fifty years. This will lead to larger amounts of nutrients in soil and surface waters, disrupting ecosystems and harming biodiversity.
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.
Synthesis of the Global Nutrient export from Watersheds project.
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...
This study presents a model for river export of dissolved SiO2, with river-basin spatial scale and an annual temporal scale. The model is based on four variables with a significant influence on DSi yields (soil bulk density, precipitation, slope and area with volcanic...
