After a lengthy period of negotiations, Greece became the tenth member of the European Economic Community. The most important problems to overcome in reaching the Treaty of Accession were those associated with the integration of Greek agriculture into the Common Agricultural Policy (CAP). The importance of the farm sector for the Greek economy as a whole, the structural problems it faces, and the political weight of the Greek farmers led to an agreement on the necessity of a five year transitional period during which Greece will have to adjust progressively to fully adopting the CAP. The major concern of this study is to examine the impact of the changes which are required for the reorientation of the Greek agricultural policy on Greece's agriculture and particularly on its feedgrain-livestock subsector. The specific objectives of the paper are: 1) to provide an overview of the organizational structure of the Greek feedgrain-livestock subsector; 2) to examine the agricultural policy in Greece and the adjustments associated with the accession to the EEC; 3) to analyze production, consumption, and trade of livestock and feedstuffs trends during the last 15 years and to project them in 1985 and 1990; and 4) to draw conclusions regarding the changes that EEC membership is going to impose on the development of the Greek feedgrain-livestock subsector.
