Assessing the impact of agri-environmental schemes on the eco-efficiency of rain-fed agriculture

This paper analyses the impact of the Agri-environmental Extensification Scheme for the Protection of Flora and Fauna (F&F Scheme) on the eco-efficiency of a sample of dryland farms in the Spanish region of Castile and Leon. Using Data Envelopment Analysis (DEA) and the so-called program decomposition approach to efficiency measurement, we explore whether or not the production technology of the farms included in the F&F Scheme is more eco-efficient than the technology used by farms that are not included in the Scheme. The results obtained confirm the foregoing hypothesis, providing evidence that environmental pressures could be reduced if all farms adopted the F&F Scheme technology. Furthermore, shadow prices are used to assess the monetary value of the potential reduction in environmental pressures that farms could achieve by adopting the F&F Scheme. The results show that the average opportunity cost of the decrease in environmental pressures ((sic)55.65 ha(-1)) is similar to the compensation received by farms included in the F&F Scheme. Nevertheless, bearing in mind the great diversity of farms, we recommend agricultural policymakers to use an auction system to award such environmental contracts.
