The CAP has introduced a higher allocation of the budget to the Agri-environmental schemes and Organic Farming over the years. In order to estimating impacts at regional level the evaluation of a Rural Development Programme single sub-measure have been considered. A FADN panel sample of Marche Region has been selected for years 2013, 2015. The application of a nonparametric matching model and the Difference-in-Difference estimator is presented. The environmental performance of organic farms is statistically different from conventional ones, therefore policy intervention has reached a positive effect. Instead, results on detected economic variables shown no differences between the two groups.
