El metabolismo social en la cuenca baja del plata: Un análisis desde los outputs para evaluar las transformaciones del entorno bioproductivo

The notion of Social Metabolism is long-standing but in recent decades have appeared novel methodologies that seek to analyse society-nature interactions. Some of these approaches have a look of black box quantifing inputs and outputs of the system while ohers aim to analyze what happens in the five social metabolic processes (appropriation, transformation, circulation, consumption and excretion). Recently it has published studies of this type for Latin America and Argentina. The hypothesis of this paper is that analyzing the evolution of the outputs we can also get an interesting perspective on the changes of the system. Focusing on the Lower Del Plata Basin as study area we suggest that through the analysis of freight logistics can track the changes that occur "upstream" in the production chain and in the environment in which they settle.
