This paper seeks to answer the following question: what are the impacts of European agri-environmental policy (AEP) on member states’ policy patterns? The concept of Europeanisation is employed, as it relates to the adaptation of domestic policies and policy instruments to existing EU legislation. An analysis of the extent to which the European level of policy-making has affected the emergence and further development of the AEP in Poland will be undertaken. Additionally, the paper examines the way in which Poland has applied Agri-environmental Schemes (AESs) and what effects this has had on the relevant Polish institutions. Empirically, this research draws on semi-structured interviews with key administrative bodies and social actors involved in agri-environmental issues.
