Fine tuning European geographic quality labels, an opportunity for horticulture diversification: A tentative proposal for the Spanish case
European horticulture, especially in the southern states, must exploit new qualities to increase the added value of its vegetables. This article aims to analyze the situation of the European geographical quality labels Protected Designation of Origin (PDO) and Protected Geographical Indication (PGI) to ascertain whether they are useful for this purpose. To this end, we studied the registers of the current horticultural products awarded PDO or PGI status, and we surveyed the authorities responsible for managing the labels for these products. We found that protected labels have grown steadily since their inception about thirty years ago, becoming a powerful mechanism for landrace conservation and a source of added benefits. The strongest points in the management of these labels include anchoring the products in the local history and culture roots and defining the prominent characteristics of their external appearance, and the weakest points are the lack of information about chemical traits and especially about sensory traits (texture, odor, taste). To strengthen PDO and PGI labels, we propose increasing the requirements for sensory descriptions, homogenizing protocols for analyzing sensory traits, incorporating methods combining trained sensory panels and instrumental methods such as spectroscopy, and involving public administrations in both obtaining and managing the labels. As an example of the potential impact of European geographical labels on territorial rebalancing and the organization of European horticulture, we propose a panoply of products in Spain that are good candidates for protected status.
