Valoración de activos ambientales mediante métodos multicriterio. Aplicación a la valoración del Parque Natural del Alto Tajo

The valuation of these goods can be a relevant element for their conservation and improvement, though the intangible and immaterial aspects of environmental assets difficult the utilisation of the traditional methods of valuation. This work presents a methodology for the valuation of those assets combining multi-criteria methods, the Analytic Hierarchy Process and the Goal Programming and traditional method the Discounted Cash Flows. The combination of both techniques allows extracting an indicator of the Total Economic Value (TEV) of an environmental asset, as well as of each partial value which make up the TEV, including tangible and intangible elements. The proposed methodology is applied to the valuation of the 'Alto Tajo' Natural Park.
