The present study provides an evaluation of the PDO/PGI scheme. The terms of reference of the project listed two key issues which were to be addressed by the evaluation study: First, the study has to provide a detailed description of the implementation and usage of the PDO/PGI scheme over the evaluation period 1992-2006; Second, the study has to evaluate the effectiveness of the PDO/PGI scheme itself. While the analysis of the implementation and usage of the scheme covers the 27 Member States over the period 1992 to 2006, the evaluation of the effectiveness of the scheme is based on publicly available information, research and academic literature, and detailed case studies of 18 PDO/PGI products in 10 Member States.
