A major source of nutrient load to periodically hypoxic Manila Bay is the urban nutrient waste water flow from humans and industries to surface water. In Manila alone, the population density is as high as 19,137 people/km2.
Growing global demand for food leads to increased pressure on phosphorus (P), a finite and dwindling resource. China is the largest producer and consumer of P fertilizer in the world. A mass balance analysis of historical P use on China's arable land shows that P input...
As in many European countries, eutrophication of surface waters is a key problem in the Netherlands, caused by high concentrations of nitrogen (N) and phosphorus (P). For implementation of the EU Water Framework Directive (WFD) in the Netherlands, surface water types have...
The proposed reform of the Common Agricultural Policy (CAP) will have little impact in developing countries. This is the conclusion by the PBL Netherlands Environmental Assessment Agency. Opportunities for the reform to have a positive effect on sustainable rural development...
Global food production strongly depends on availability of nutrients. Assessment of future global phosphorus (P) fertilizer demand in interaction with nitrogen (N) and potassium (K) fertilizers under different levels of food demand requires a model-based approach. In this...
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. Importantly, the waste from fish or shellfish cannot easily be managed, as...
Standardised exposure scenarios play an important role in European pesticide authorisation procedures (each scenario is a combination of climate, weather and crop data to be used in exposure models). The European Food Safety Authority has developed such scenarios for...
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...
