摘要:ACRE is an Agro-eConomic model for agricultural pRoduction at rEgional level. Based on an extension of Positive Mathematical Programming (PMP) this model was developed as a decision tool for politics with respect to questions of global change- and political scenarios. ACRE was applied in two interdisciplinary projects for simulation of agricultural production in two German river basins. Currently, the model was extended to calculate agricultural production for the federal state Baden-Württemberg in South West Germany. This paper introduces the results of CAP scenario calculations with the regional model ACRE for Baden-Württemberg.
