Since 1900, N export by the Yangtze river increased 17-fold and that of P 7-fold. This dramatic increase in coastal nutrient loading could lead to declining oxygen concentrations waters, and the increase in molar N:P ratio could increase the risk of harmful algal blooms.
NewClimate Institute, PBL Netherlands Environmental Assessment Agency and IIASA present an overview of on climate change mitigation policies in 25 major emitting countries/regions that have been adopted since July 2017. The policy information compiled by in this document...
At least once every 5 years Dutch Parliament receives a report about the efficiency and the effects of the Manure and Fertilisers Act. In the report it is concluded that the manure policy has not improved the Dutch water quality substantially in the past 10 years.
The BioScore 2.0 model analyses impacts of human-induced pressures on European terrestrial biodiversity. The model can be used for scenario analysis and the assessment of policy options. This report provides a detailed description of the methodology and examples of the...
Livestock production systems currently occupy around 28% of the land surface of the European Union (equivalent to 65% of the agricultural land). In conjunction with other human activities, livestock production systems affect water, air and soil quality, global climate and...
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.
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, with emphasis on voluntary or incentive-based schemes in the United States...
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...
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...
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...
