To promote the consumption of local and quality food from small producers, it is necessary to diversify distribution channels and promote local scale processing (canned fruits and vegetables). This allows to give a better value to the products during peak production and improved food security. The collaborative economy is a societal trend, who can play an interesting role here : more and more citizens involve themselves in food (see the development of CSA or consumer cooperatives eg ). However, developing a local and collaborative processing food , it is necessary both to Learn to work together producers and consumers to respect specific rules of production and be organized to be able to transmit knowledge to a non-professional public And this is the purpose of this project : create and implement the conditions for diffusion of a "training of trainers " to farmers and consumers and citizens , motivated to create and facilitate collaborative workshops (for fruits, vegetables, cheese ) We rely on « learning by doing » pedagogy : the content of the training will be developed and validated during testing sessions. Beyond the project group (eight people from four European countries), all involved in the re-localization of the economy , twenty people and resources persons will benefit from the action directly during the project. But the challenge is to deliver the training of trainers to 20 - 25 people per year in each partner country and thus to encourage the creation of « collaborative workshops food processing » . This theme , which contribute to several priorities of the European Union (environment protection, food security , employment) is also a source of cultural and gastronomic exciting exchanges. It will allow us to give this project a European dimension both in terms of educational innovation and in terms of culture.
