Abstract
La degradación territorial asocia condiciones de pobreza local y erosión hídrica; ambos procesos convergen espacialmente y se potencian en forma progresiva. Sin embargo, son escasas las propuestas metodológicas de zonificación. El objetivo de este trabajo es definir distintos niveles de zonas territorialmente degradadas en la cuenca del estero Tabolguen, comuna de Cauquenes, VII Región de Chile. Esta zonificación pretende establecer prioridades en la gestión pública local, con miras al mejoramiento de la calidad de vida de la población. La definición de zonas territorialmente degradadas se logra a partir de la integración espacial del riesgo de erosión hídrica real y pobreza. El riesgo de erosión hídrica real se analiza a partir de variables edafológicas, climáticas, topográficas y vegetacionales; la pobreza, por su parte se estudia a partir de un análisis de necesidades básicas insatisfechas y vulnerabilidad. Se definen cuatro niveles de zonas territorialmente degradas. A partir de los resultados obtenidos, se concluye la pertinencia del modelo en el área de estudio por su representatividad, operatividad y sencillez. Se recomienda la aplicación de esta metodología en otras unidades territoriales similares en lo biofísico y social.
Territorial degradation associates local poverty conditions and hydric erosion; both processes converge and they are strengthen progressively. Nevertheless, methodologic proposals of zonification for the territorial degradation are scant. This project aims at defining different levels of degraded territorial zones in the basin of the Tabolguén swamp, commune of Cauquenes, VII Region of Chile and establishing priorities to the local public management, as to sequening the improvement of the population’s quality of lif.. The definition of degraded territorial zones results from the integration of the risk of real hydric erosion and poverty. The risks of real hydric erosion are analyzed from variable soil , climatic, topographic and vegetative conditions; besides,poverty is studied from the analysis of not satisfied basic needs and vulnerability. Four levels of degraded territorial zones are defined. From the outcomes, the pertinence of the model in the study area was concluded by its representativeness, operativity and simplicity. The application of this methodology in other territorial units of biophysic and social similarity is recommended.
