摘要：Social metabolism analysis gives the conceptual basis to understand interactions between society and nature. Beyond this perspective and the systems theory, this article analyzes at different scales social and economic relations of three natural resources management systems in a rural community from Mexico. A system typology was constructed based on the productive components and local institutions. Each system was studied considering three types of fluxes: i) monetary fluxes from subsidies; ii) material fluxes from agricultural and livestock production and iii) labour fluxes. A characterization of these fluxes was made at three scales: i) productive component (maize, livestock and forest); ii) parcels (system) and iii) community. The results showed that there is a negative interaction between subsidies and productive diversification and a positive interaction between number of components and labour demand. Subsidies for commercial forest plantations and social organization are associated with the diminution of agricultural area and an increase of forest cultivated surface. These results had shown some of the internal and external factors that affect peasant strategies of natural resources management and its implications with self sufficiency.
