Nachhaltiger Anbau von Bioenergie : eine ökonomisch-ökologische Analyse für die Landwirtschaft in Baden-Württemberg
(2012) Konold, Angelika; Zeddies, Jürgen
The aim of this thesis is on the one hand to estimate the potential of energy crop production for CO2-sequestration in Baden-Württemberg. On the other hand the focus lies on the interactions that arise from the implementation of optimized na-ture conservation measures with the land management on regional level. For this the existing economic-ecological regional model EFEM (Economic Farm Emission Model), based on linear programming, is further developed. The calculations are made on farm level and are extrapolated on regional level. The model is calibrated on the database for the years 2001-2005 and the so modeled Reference_2003 than is projected to the year 2015 (BAU_2015), this to evaluate the model results without the influence of the great changes in agricultural policy in the last years. Based on the modeled situation for the year 2015 further scenarios are defined that differ in the expansion of energy cropping and nature conservation measures. In the ?biomass scenarios? only the legal nature requirements have to be met while in the corresponding ?conservation scenarios? restrictions that are optimal from a nature conservation point of view, must be considered. The sensitivity analyses for selected parameters proved that the model results have sufficient stability to make reliable statements about synergy effects and conflicts between the expansion of energy crop cultivation and requirements for natural conservation. Altogether it could be shown that with the used model approach interactions be-tween the cultivation of energy crops and nature conservation are represented sufficiently and the objectives of energy and climate policy are compatible.
