Structural changes going on in Brazilian agrarian activity interface with scientific and technological development within the field. The establishment of a new reference in agrarian Science and Technology is a new possibility for rebuilding consensus around the notion of competitiveness, which brings backs labor's positive central role, now linked to individual responsibility and efficiency, perpetuating and deepening differences through unequal access to opportunities. The study includes the conceptual conflict between agroindustries' competitive rationality, which prioritize productivity aimed at accumulation _ recreating forms of submission by downplaying what is traditional and through political demobilization _ and the rationality of those farmers which, through their organizations, prioritize social reproduction and sustainability of their like and production mode. The opposition between the concept of productivity and that of social reproducibility or sustainability as part of the notion of competitiveness adds to the generation of a resistance culture, specially between family farmers. Instability and decrease in public investments in research and technology, not offset by private ones, compromise Brazilian agrarian activity future competitiveness.
