Resumen
Las alarmas ante la pérdida de biodiversidad y la degradación de los sistemas socio-ecológicos sobre dimensionados por los escenarios de cambio climático global han traído a escena una serie de conceptos y prácticas, guiadas por objetivos de sustentabilidad, conservación y restauración. Dentro de este marco, la noción de renaturalización recupera estas preocupaciones. Se presenta como un ambicioso proyecto tendiente a recuperar algo o volverlo a un estado anterior, a incrementar la heterogeneidad ambiental, la biodiversidad y reducir las intervenciones humanas (Lorimer et al, 2015). No obstante, la idea de renaturalización no impresiona homogénea (Jørgensen 2015). No sólo no hay acuerdo en cuál es ese momento previo al que hay que volver, tampoco qué debe ser recuperado y quiénes definen la conformación de esos recortes. Situada en la Diagonal Árida Sudamericana, la ciudad de Mendoza (Argentina) ha incorporado recientemente las ideas de regeneración urbana y renaturalización, como caminos a horizontes de sustentabilidad y oferta de servicios ecosistémicos, especialmente en el entorno de los ríos urbanos y espacios públicos asociados. En este contexto, el presente trabajo problematiza las nociones de regeneración urbana y renaturalización como dispositivos tecnológicos de un cúmulo de acciones tendientes a la sustentabilidad de los paisajes fluviales urbanos. En base a un estudio de caso que se despliega sobre la ciudad de Mendoza y se recurre al uso de metodologías mixtas, se revisa el alcance y contenido que estas nociones reciben en los organismos públicos con competencia en los territorios asociados a los ríos urbanos para analizar luego los conflictos y tensiones territoriales que se suscitan.
The alarms surrounding the loss of biodiversity and the degradation of socio-ecological systems, over-dimensioned by global climate change scenarios, have brought to the forefront a series of concepts and practices guided by sustainability, conservation, and restoration objectives. Within this framework, the notion of rewilding addresses these concerns. It is presented as an ambitious project aimed at recovering something or returning it to a previous state, increasing environmental heterogeneity and biodiversity, and reducing human intervention (Lorimer et al., 2015). However, the idea of rewilding does not appear homogeneous (Jørgensen, 2015). Not only is there no agreement on the point before the return is necessary, nor is there agreement on what should be recovered and who defines the makeup of these reductions. Located on the South American Arid Diagonal, the city of Mendoza (Argentina) has recently incorporated the ideas of urban regeneration and renaturalization as paths toward sustainability and the provision of ecosystem services, especially in the surroundings of urban rivers and associated public spaces. In this context, this paper problematizes the notions of urban regeneration and renaturalization as technological devices for a range of actions aimed at the sustainability of urban riverscapes. Based on a case study of the city of Mendoza and employing mixed methodologies, the scope and content of these notions are reviewed by public agencies with jurisdiction over territories associated with urban rivers, and then the territorial conflicts and tensions that arise are analyzed.
