The methodology used for Economic Valuation of the Externalities generated by the Watershead Restoration and Erosion Control Projects in the Hydrographic Basins of the Mediterranean Slope, is based on the Replacement Cost Method. Environmental Economics, however, today offer us other methodological possibilities, whose application to the valuation of this type of project may prove to be of interest. It is the case of the Contingent Valuation Method used for the evaluation of the effects of the Watershead Restoration and Erosion Control Projects of the Aljibe Basin (Almería) Spain, presented here. The results obtained show that, in this case study, application of Contingent Valuation ascribes greater social profitability of the project, with 5.23 % of IRR (Internal Rate of Return), compared to the value obtained using classic methodology of 2.25%, thus enabling us to draw closer to the true socio-environmental value of this type of project. In any case, both possibilities rather than alternatives can be considered as complementary, by focusing on the valuation from different perspectives.

Voluntary environmental agreements have been popular with government agencies in several countries. However, many questions remain about their efficiency as a regulatory tool. Recent analyses suggest that they are more effective than conventional regulatory or economic approaches when dealing with diffuse pollution and when innovation processes at the source are necessary to define effective regulation. This paper applies an activity-based framework to assess the contribution of such a voluntary agreement to the environmental performance of farms participating in a whole farm plan in the Southern part of Belgium. Using a cross-section of 52 farms, our results show that farms entering into environmental agreements are environmentally more efficient than non-participating farms in terms of the preservation and provision of landscape features. However, their environmental efficiency with regard to the reduction of non-desirable outputs, such as organic nitrogen, is mostly determined by technical efficiency and not by participation in the whole farm plan.
