Abstract

RESUMEN: Entre las externalidades producidas por la actividad agraria hay que considerar su aportación a la configuración del paisaje, es decir, la externalidad estética de los agroecosistemas. Su conocimiento y valoración adquiere cada vez más relevancia. En el presente trabajo se han utilizado los métodos de Análisis Conjunto y Valoración Contingente para estudiar, por una parte, la importancia relativa de la componente agraria en la función de utilidad derivada del disfrute de los paisajes de Las Alpujarras (Granada-España) y, por otra, la disposición a pagar de los entrevistados por disfrutar de dichos paisajes. Se ha realizado un test a una muestra de potenciales visitantes a la zona, utilizando tres elementos básicos de los paisajes: cubierta vegetal, pendiente y nivel de edificación. Dentro de cada uno de estos componentes del paisaje, se han considerado distintos niveles, algunos relacionados con la actividad agraria. Posteriormente, se ha ajustado un modelo de regresión múltiple con el fin de identificar la relación entre la Disposición a Pagar por disfrutar de cada uno de los paisajes considerados y los atributos del mismo y las características sociodemográficas de los entrevistados. Los resultados de los análisis de preferencias y de la Disposición a Pagar han permitido identificar líneas estratégicas para potenciar la función paisajística de los sistemas agrarios de la zona con vistas a su desarrollo endógeno, integral y sostenible. PALABRAS CLAVE: Análisis Conjunto; Valoración Contingente; Paisaje Agrario; Desarrollo Rural Sostenible. SUMMARY: Among the externalities produced by agrarian activities one must consider its contribution to the shaping of the landscape, an aesthetic externality value of the agrosystems. Recognizing and appraising this contribution is becoming more and more important every day. In this study a Conjoint Analysis and Contingent Valuation methods has been used to estimate, first the relative importance of the agrarian component level in the utility function achieved from enjoying landscapes, and secondly the Willingness To Pay of surveyed for these landscapes existing in the area of The Alpujarras (Granada-Spain). Data has been obtained by a questionnaire performed to a sample of a potential visitor of the area, using three main features of landscape, as follows: Vegetation layer, level of building, and mountain inclines, each of them with different levels. Subsequently, a multiple regression model has been fitted to identify the relationship between the Willingness to Pay for landscapes and its features and the socio-cultural traits of the individuals. According to results concerning both the preferences and the Willingness To Pay of visitors for landscapes, some conclusions have finally been drawn, allowing to derive strategies to maintain the most valued landscape in the area and to make use of it for the sustainable development of the region.
