Agriculture and forestry play an important role in emitting and storing greenhouse gases. For an efficient and cost-effective climate policy it is therefore important to explicitly include land use, land use change, and forestry (LULUCF) in economy-climate models. This paper gives an overview...

The contribution of biofuels to the saving of greenhouse gas (GHG) emissions has recently been questioned because of emissions resulting from land use change (LUC) for the bioenergy feedstock production. We investigate how an expanding biofuel feedstock production impacts on land use dynamics if...

Marine and coastal ecosystems - and thus the benefits they create for humans - are subject to increasing pressures and competing usages. For this reason, the European Union (EU) adopted the Marine Strategy Framework Directive (MSFD), which is to guide future maritime policy in the EU and aims at...

The contribution of biofuels to save greenhouse gas emissions has been challenged over the last years. A still unresolved question is how to quantify emissions from indirect land use change (iLUC). In this article we discuss the implications of uncertainties on the current policy proposals in...

Climate change affects the physical and biological system in many regions of the world. The extent to which human systems will suffer economically from climate change depends on the adaptive capabilities within a region as well as across regions. We use an economic General-Equilibrium model and...

The goal of this technical paper is to present in a transparent way a detailed description of the DART-BIO model - the bioeconomy and land use version of the DART model. Key feature of the DART-BIO model is the explicit representation of the vegetable oil industry and the biofuel sector. The...

Last year the German Parliament exempted biofuels from the gasoline tax. The promotion of biofuels is being justified by allegedly positive effects on climate, energy, and agricultural policy goals. The paper takes a closer look at bio-ethanol as a substitute for gasoline. We analyze the basic...

In June 2002 the German Parliament decided to exempt biofuels from the gasoline tax. The policy to promote biofuels is being justified by allegedly positive effects on the climate, energy, and agricultural policy. The working paper takes a closer look at bio-ethanol as a substitute for gasoline...

We use the new version of the GTAP-W model to analyze the economy-wide impacts of enhanced irrigation efficiency. The new production structure of the model, which introduces a differentiation between rainfed and irrigated crops, allows a better understanding of the use of water resources in...

Based on predicted changes in the magnitude and distribution of global precipitation, temperature and river flow under the IPCC SRES A1B and A2 scenarios, this study assesses the potential impacts of climate change and CO2 fertilization on global agriculture. The analysis uses the new version of...
