Abstract

El presente trabajo trata de evaluar los efectos externos de la erosión del suelo mediante el uso del método del Experimento de Elección (EE). Tras una breve revisión de la literatura socioeconómica sobre el problema de la erosión y de los métodos empleados para evaluar sus efectos, se describe una aplicación a la evaluación de los efectos externos de la erosión del suelo en la cuenca del Alto Genil (Granada). El empleo del método del EE permite el cálculo de los valores asociados a los impactos más importantes de la erosión, así como proporcionar al administrador público información útil para la determinación de prioridades de gestión en el contexto de la planificación territorial. También se estima la variación de bienestar que la aplicación de políticas de reducción de la erosión del suelo, y sus efectos externos, induce en los ciudadanos. Dichas valoraciones se compararán con las actuales ayudas que la Consejería de Agricultura y Pesca de la Junta de Andalucía reconoce a los agricultores que adoptan métodos de producción agraria de conservación del suelo. Palabras claves: Valoración monetaria, Externalidades, Experimento de Elección, Erosión. Abstract The paper presents the economic evaluation of the soil erosion off-farm effects by means of the Choice Experiment method. After a review of the main studies that consider, under a socio-economic point of view, the soil erosion problem an application of the choice experiment to monetary evaluation of the off-farm effects of soil erosion in the Alto Genil watershed (Granada province) is described. The choice experiment method allows the estimation of the values of the most important soil erosion impacts, so that to provide public-decisors with useful information regarding land management. Also, the welfare change experimented by citizens, due to the implementation of soil erosion reduction policies, is investigated. These evaluations will be compared with the subsidy that the regional government grants to farmers that adopt soil conservation measures.
