Résumé
Natural environments provide essential services to sustain life on the planet, and protected areas have been the classic instrument to conserve and protect these places, where private owners have participated by complementing the National System of Protected Areas. Protected areas, like all natural spaces, are being affected by the impact of various global changes (GC) to which they must adapt. An important aspect to face GCs are the management plans, involving zoning models whose objective is ordering the territory according to sectors with homogeneous attributes. In Chile, methodologies for incorporating the dynamism derived from GCs in the zoning process and which allow to know the change in the demands and decisions for a wildland area management have not been reported as yet. The present study aims to propose, in the global change context, a dynamic zoning of the Huasco Altinos Private Protected Area, in the Atacama Region, Chile. The Model of Zonal Vocation Use was utilized to obtain the current area zoning. The proposed innovation consisted in applying a prospective approach, i.e. to generate future scenarios starting from a structural and morphological analysis supplying the most important variables of the territory and their possible responses to global changes. This modification in the variables, represented in two scenarios, was the input information to establish two new zonings. The maps obtained correspond to baseline and alternative scenarios that when compared presented not extremely contrasting differences. However, both scenarios have marked differences with initial zoning (current status), which denotes that in general there is a potential sensitivity in the area management to changes in its components. Finally, it was concluded that the prospective approach allows the incorporation of dynamism in the protected areas management and contributes methodologically to this purpose. By considering future scenarios, decision making concerning such management is improved since it allows to foresee the most important uses and, consequently, to prioritize actions.
