Rural worlds are about experiencing global changes impulsed by new forms of agrarian capitalism. The new agenda for Latin America development sees the interaction between old and new trends, which produces new conflicts. This paper takes the socio-economic doctrine of so-called neo-structuralism as a starting point for analysing policies on family farming under different perspectives: the role of the State, agricultural development models, the role of the market, the relations between different actors in the public sphere in terms of discourses and debates. The working hypothesis of the paper is to analyse Argentina as a case study, not as much as an example but rather as a specific case, which is developing in political frames and trends common to America Latina as a whole. This allows me to detect new processes of inclusion of family farming in the economic model, as well as traditional logic of its exclusion and subordination to the mainstream.
