The Strategic Project for Food Security of FAO in Mexico, operating since 2003, has promoted actions and productive projects in order to improve household food security in regions with high level of poverty in the country. This study evaluates the effects of the Program intervention in indigenous Tzotzil communities of the coffee-producing micro region located in Altos of Chiapas Region, Mexico. A descriptive and evaluative study was carried out comparing baseline dated before the intervention and between groups with and without the Program. Results showed that the food insecurity persists in the population. Families live mainly from agriculture and the coffee sales. However, more infrastructure and production opportunities were found in communities where the Program intervened. In relation to the data prior to intervention, in both groups no significant changes in annual household income were found. Despite this, an increase in the proportion of income destined to food was found. The Program only partially considered the indigenous cultural elements during the intervention, given that the resource and productive projects allocation in the localities were conducted with weak processes of social participation.
