Investigating citizens' preferences for recycling residual organic products in agriculture : a choice experiment approach

Abstract : This paper presents the results of an empirical study recently conducted in the Paris Basin, aimed at estimating the economic value of using Residual Organic Products (ROPs) as fertilizers, compared to a standard mineral fertilization. A Choice Experiment approach allows to assign monetary values to the positive and negative environmental externalities associated with different modes of fertilization by ROPs or mineral fertilizers. The paper addresses in particular 3 environmental effects: the organic waste recycling, the soil erosion closely linked to a potential long-term modification of fertility of soils, and the pollution of soils.
