Ambitious renewable energy targets have been implemented in the EU that can only be attained if further policy measures are taken to boost, among others, bioenergy production on agricultural land. The aim of this article is to explore consequences for land use, environment, and policy if bioenergy crop production will be expanded in Austria considering constrained arable land availability. In a policy experiment, we assess the bio-physical and economic production potentials of bioenergy crops and explore the trade-offs between food, feed and bioenergy crop production on arable lands in Austria. In particular, we analyze how costly it is to expand domestic bioenergy crop production by employing an integrated modeling framework using an elaborated set of bio-physical and economic data. The results indicate that an expansion of bioenergy crop production for first and second generation biofuels would imply significant adjustment costs for the agricultural sector. Furthermore, increasing feedstock production would have significant impacts on land use and fertilizer intensity levels. The economic analysis considers regional contexts and bio-physical site conditions, which should better reflect the differences in opportunity costs, and hence, lead to higher feedstock costs as estimated in previous studies. Subsidies on domestic bioenergy crop production induce higher regional food and feed prices as well as leads to higher land prices in a land constrained economy.
