The knowledge and the cultural heritage concerning traditional recipes based on local and ancient crop varieties are very diffused in small rural areas and in local communities, in particular in Italy. This kind of knowledge, if well recognised and documented, can contribute to the sustainable development of territories in which it developed through oral transmission of local people. The traditional knowledge concerning food and foodways, that can be interpreted in terms of intangible heritage asset of the territory, in this paper is studied using the logic of Knowledge Transfer (KT). In fact, a crucial step for the preservation of the knowledge for future generations is the involvement of local communities, in order to elicit and to track the information of which they are custodians. The final goal is to engage them in the management of food knowledge for the sustainable economic, social and environmental development of their territory; in other words to preserve the social capital for future generation. The objective of the paper is to conduct a survey, in a very specific territory, that is the “Bio-Distretto della Via Amerina e delle Forre”, in Central Italy, in order to gather information concerning the actual awareness of local people and organizations concerning their food heritage and the values (cultural and economic) they attribute to it. The information retrieved will then be used as a basis for the preparation of a theoretical framework of valuation and management of food heritage through citizen engagement in other areas/organizations. The survey will have the structure of a questionnaire, used to elicit awareness, feelings and wishes about the food heritage and their desired management for the development of the territory, in order to achieve information about cultural and economic values of this heritage. In particular, for the latter type of values, a Contingent Valuation Method (CVM) will be used. The expected result in terms of Knowledge Management and Transfer will be the development of a tool that can be interpreted as a Participatory Rural Assessment (PRA) method. Indeed, the mix of surveys and public engagement techniques aimed at understanding the values and knowledge that local populations in Bio-Districts wish to sustain allows an informed and communitarian preservation of food intangible heritage.
