Development programs need to broaden their assistance works so as to reach the poorer population in the shape of concrete alternatives in very localized action fields. This is the case of the free agri-fairs by family agriculturists. Such fairs come to be the main commercial link between the producer and the urban center society which allows him to fare income to his family. Thus, this paper analyses the dynamic familyagriculturists’ fair in Turmalina town., Alto Jequitinhonha, MG. When analysing the problematic of producers in the fair and their relationship with other social agents, one seeks to understanding the reach of the fair in economical terms, that is, the workforce used and the forms of income-building to this local market. A fundamental part of the research consists of identifying the spaces of social and cultural reproduction of the families that participate in the fair, was well as the performance and participation of members of the family unit in its productive organization.
