Wpływ zazielenienia Wspólnej Polityki Rolnej na wyniki ekonomiczne gospodarstw roślinnych

The paper presents assessment of impacts of introducing the greening scenario of the Common Agricultural Policy, proposed by the European Commission as an alternative for the reformed CAP after 2013. A number of variants of the greening was analyzed. Assessments were made for selected types of crop farms from the FADN sample with the use of the LP optimization farm model. Types of farms were defined according to the level of diversification of crop production, that was calculated with the index of concentration of cropping structure CCI. Greening of the CAP leads to changes in the cropping structure. Required diversification of cropping structure and obligatory 7% of ecological focus area results with a decrease of farm incomes comparing to baseline scenario, that assumes continuation of the current CAP.
