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.
