Economic analysis of soil erosion: The off-site effects evaluation in the Genil basin

Sergio Colombo, Javier Calatrava Requena

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.
