Family farming and sustainable development are the subject of intense debate regarding their feasibility to promote the development of the Amazon Region. As a result of the social movements of the rural and extractive workers, the struggle and resistance for the preservation of the forest resulted in the implementation of the Extractive Reserve (RESEX) Chico Mendes. The aims of this article are to evaluate the innovative dynamics and the investment in RESEX Chico Mendes, located in the State of Acre, in the last 20 years. For this evaluation, the methodology used by the ASPF Project (Socioeconomic Analysis of Rural Family Production of Acre), developed at the Federal University of Acre (UFAC), is used, based on economic indicators such as efficiency and reproductive tension, as well as the typology of families. The results indicate that rural family production based on RESEX Chico Mendes still faces reproductive difficulties, lacking public policies and investments in the search for new sustainable technologies.
