In 2003, the new CAP reform for EU member states (MS) was decided by the European Commission. CAP reform scenarios have been calculated here for Southern Germany using the regional model ACRE. By using statistical data found for agricultural production in England ACRE was calibrated for England and CAP reform scenarios have been calculated. This study presents the calibration of ACRE to England and results of CAP reform scenario calculations for the Southern German Neckar river basin and England.
