Share of raw material costs in total production costs
The share of raw material costs in the total costs for producers can be calculated using different methods. This note compares two of these methods; the energy and material costs and the basic raw…
In ‘The Netherlands in 21 infographics – Facts and figures on the human environment’ the PBL Netherlands Environmental Assessment Agency presents facts and figures in a novel way. The booklet covers…
Key role of China and its agriculture in global sustainable phosphorus management
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…
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…
Crop yield response to soil fertility and N, P, K inputs in different environments: Testing and improving the QUEFTS model
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…
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…
The provision of public goods by agriculture: Critical questions for effective and efficient policy making
Agriculture produces both marketable and public goods, such as landscape and farmland biodiversity. The provision of these public goods is often under pressure as a result of various developments…
A modelling approach for the assessment of the effects of Common Agricultural Policy measures on farmland biodiversity in the EU27
Greening of the EU Common Agricultural Policy (CAP) may help to achieve targets of the EU Biodiversity Strategy to 2020. A suite of models can ne used to calculate the impacts of policy measures…
The global nitrogen cycle in the twenty-first century
Global nitrogen fixation contributes 413 Tg of reactive nitrogen (Nr) to terrestrial and marine ecosystems annually of which anthropogenic activities are responsible for half, 210 Tg N. The majority…
Assessing agricultural risks of climate change in the 21st century in a global gridded crop model intercomparison
