All over the world local animal breeds and plant varieties combined with the traditional knowledge of small-scale farming and craft enterprises provide the basis for a range of local products that are sold beyond the region as specialities. Black Forest ham，champagne，Nuremberg gingerbread-the list could be continued；in Europe alone 564 products from 15 countries have so far been registered. In addition these traditional products often have their own history which，alongside the product’s quality and the appeal of traditional methods of manufacture，provides an additional purchase incentive for the consumer.
