Abstract
This document presents an analysis of the Lonquimay and the Curacautin landscapes as a socio-ecological system. The two commune areas constitute the Araucarias of Alto Malleco Forest Model in Chile, respective headwaters of the Bio Bio and the Cautin rivers. The first section introduces the analysis, by presenting its context, the issue addressed and the objective of analyzing socio-ecological dynamics. The second section, Material and Methods, tells how the analysis was led in Lonquimay and in Curacautin, presenting the PARDI method (Problem-Actors-Resources-Dynamics-Interactions) and describing the fieldwork for building conceptual models that allow to visualize practices of land use and water management. The third section of the document presents results. They consist in the formulation of the water security problem that the people of Lonquimay and Curacautin considered a central and shared issue; in the characterization and location of actors and resources that are involved in this problem; and in the representation of the main dynamics and interactions that link those actors and resources. For each landscape, two conceptual models were built, from the biophysical and the legal standpoints. The discussion section deals with the possibility to integrate both standpoints; with the mere modelling process, and; with the cost elements of water access. Main uncertainties highlighted by the analysis are revised and the report concludes by summing up our major findings in this participatory investigation process on socio-ecological dynamics.
