The Metropolitan Region of Buenos Aires (RMBA) is the main urban conglomerate of the Argentine Republic. It is configured as a semicircular territory developed around the Autonomous City of Buenos Aires (CABA), whose diameter rests on the estuary of the Río de la Plata. The rivers and streams that flow into it are arranged in radial bands, forming geographical features that are decisive for urbanisation. The historical relationship between watershed’s system and the population process has been the subject of various environmental conflicts. The purpose of this article is to make visible the interactions between nature and urbanisation in the RMBA, taking watersheds as units of analysis, and the landscape as a theoretical and methodological approach. Two representative cases are analysed: del Gato stream basin, the most urbanised in the La Plata district (capital of the province of Bue...
