Espacios fronterizos del sur sudamericano. Propuesta de un modelo conceptual para su estudio.

This is a conceptual model for the comparative geographical study of border areas formed between national states. The empirical systematization this proposal is based on has been carried out in southern South America, defined as the area where, during the nineteenth and twentieth centuries, the territories of six national states were differentiated: Argentina, Bolivia, Brazil, Chile, Paraguay and Uruguay. This article aims to renew the studies on Argentine borders, from a critical geographic tradition point of view and based on a relational and multiscalar aspect on the construction of territories. The model recognizes six main components for the study of border areas: territorial differentiation, frontierization, internal territories, external territories, border areas and mobilities.
