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...

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...

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...

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...

In the context of energy security and climate protection, biomass is given high importance. Nevertheless, land-use conflicts resulting from the cultivation of biomass and their economy-wide effects are yet to be fully understood. To shed light on this issue we link three distinctive models; a...

Biogasproduktion wird in Deutschland mit dem Ziel des Klima- und Umweltschutzes sowie der Substitution fossiler Energieträger durch das Erneuerbare-Energien-Gesetz (EEG) gefördert. Dieser Beitrag analysiert quantitativ durch Kopplung eines Agrarsektor- und eines Standortmodells die...

Large-scale agricultural investments (LSAIs) typically depend on strong formal institutions and market-oriented intensive farming, whereas informal institutions tend to characterize the traditional villages located around them. We investigate changes to social capital in such villages when LSAIs...

In light of the surge in large-scale farms in developing countries, concerns have been raised that smallholders may be negatively affected. There is, however, very little evidence beyond case studies to support these claims. Drawing on nationally representative household data sets and an...

The paper discusses the decisions on the CAP in the context of the Berlin summit. In a rather broad perspective the agricultural sectoral and related objectives are analyzed for their consistency and compatability with higher ranking societal objectives. The policies' allocational and...
