Objetive:

Is to analyze food sovereignty as a social process, based on a case study in La Trinitaria, Chiapas.

Methodology:

A participatory methodology was applied to analyze the experience of the popular school “Learning Center for Peasants and Indigenous Development” (CEFADECI, by their acronyms in Spanish), where members of the Emiliano Zapata Peasant's Organization-Plan de Ayala National Coordination (OCEZ-CNPA) have being trained in agroecology topics since 2008. The methodology included qualitative interviews, transects and meetings with peasants of five rural communities in La Trinitaria municipality, in Chiapas. The Glissman's typology of agroecological process was used to analyze the different stages that the organization members are in their social construction of food sovereignty.

Results:

We highlight the social process and strategies to scale out agroecology for the construction of food sovereignty and the difficulties faced by the peasants to achieve it.

Limitations:

Within the limits of this paper, is that the systematization of experiences can include recommendations to improve organization process, but not necessarily have been taken into acount by the militants of social organizations.

Conclusions:

Among the conclusions are reached stands that the food sovereignty social construction's strategy can be improving whit an agroecological training and production program.
