| This paper examines the potential impact of agricultural and trade policy reform on land-use across the EU focussing particularly on the issue of land abandonment. Using a novel combined application of the well established CAPRI and Dyna-CLUE models it estimates the extent of change across Europe under removal of Pillar 1 support payments and trade liberalisation. Overall, it is estimated that around 8 per cent less land will be farmed under these reforms than under the baseline situation. However, some regions, areas and farm types face more significant reductions. The reforms are particularly felt on livestock grazing farms situated in the more marginal areas of Europe, which also coincide with areas of high nature value. Therefore, farmland biodiversity... |

| In Germany, since several decades the RAUMIS modelling system is applied for policy impact assessments to measure the impact of agriculture on the environment. A disaggregation at the municipality level with more than 9.600 administrative units, instead of currently used 316 counties, would tremendously improve the environmental impact analysis. Two sets of data are used for this purpose. The first are geo-referenced data, that are, however, incomplete with respect its coverage of production activities in agriculture. The second set is the micro census statistic itself, that has a full coverage, but data protection rules (DPR) prohibit its straightforward use. The paper show how this bottleneck can be passed to obtain a reliable modelling data set at... |

| When building an economic model for supply analysis the aim is to model a decision making process of one or more agents which fits the observed practice as good as possible. Hereby the modeller is often confronted with incomplete information about the production process; particular crop specific input data are rarely available. The problem of defining activity related technology inputs coefficients is not new. A good deal of literature comes from the mathematical programming perspective, where input coefficients were estimated using a standard linear regression function to fully represent the mathematical program. However this approach is a pure technical device and may result in an inconsistent model. The author of the paper wants to investigate whether... |
