Locked into Copenhagen pledges — Implications of short-term emission targets for the cost and feasibility of long-term climate goals
This paper provides an overview of the AMPERE modeling comparison project with focus on the implications of near-term policies for the costs and attainability of long-term climate objectives. Nine…
Implications of alternative assumptions regarding future air pollution control in scenarios similar to the Representative Concentration Pathways
The uncertain, future development of emissions of short-lived trace gases and aerosols forms a key factor for future air quality and climate forcing. The Representative Concentration Pathways (RCPs)…
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…
Regional GHG reduction targets based on effort sharing: a comparison of studies
The IPCC Fourth Assessment Report noted that Annex I countries’ targets for 2020 would need to be 25% to 40% below the 1990 level to be in line with the 2° Celsius (C) target. What is the equivalent…
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…
The European Commission has launched a discussion with its Green Paper on climate and energy policies. PBL has analysed the effects of various assumptions on Member States' emission targets for 2030…
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…
Comments on the European Commission's Green Paper ‘A 2030 framework for climate and energy policies’
The European Commission has recently published a green paper titled ‘A 2030 framework for climate and energy policies’. In that document, the Commission formulated a number of questions for public…
Assessing agricultural risks of climate change in the 21st century in a global gridded crop model intercomparison
Here we present the results from an intercomparison of multiple global gridded crop models (GGCMs) within the framework of the Agricultural Model Intercomparison and Improvement Project and the Inter…
