    INTRODUCTION  MATERIALS AND METHODS  Productivity of silvopastoral systems under Pinus radiata D. Don estimated with the Yield-SAFE model  Ferreiro-Domínguez N1,2, Palma JHN2, Rigueiro-Rodríguez A1, Mosquera-Losada MR1  1Crop Production and Project Engineering Department.

Universidad de Santiago de Compostela, 27002 Lugo, Spain 2Forest Research Centre, School of Agriculture, University of Lisbon, Tapada da Ajuda, 1349-017 Lisboa, Portugal E-mail: mrosa.mosquera.losada@usc.es  RESULTS   CONCLUSION: the LER simulated by the Yield-SAFE model was 1.41 which indicates that the hypothetical silvopastoral system of this experiment was more productive than the exclusively forest and agricultural systems probably due to the diversified production of the silvopastoral systems. Therefore, the establishment of silvopastoral systems could be promoted around the Europe due to its high productivity compared with the exclusively forest and agricultural systems which is increased by the non-market products that the agroforestry systems support  ACKNOWLEDGEMENTS We acknowledge support of the European Commission through the AGFORWARD FP7 research project (contract 613520) and Xunta de Galicia, Consellería de Cultura, Educación e Ordenación Universitaria (Programa de axudas á etapa posdoutoral DOG nº122, 29/06/2016 p.27443, exp: ED481B 2016/071-0). The views and opinions expressed in this report are purely those of the writers and may not in any circumstances be regarded as stating an official position of the European Commission      To determine the productivity of exclusively forest and agricultural systems and a silvopastoral system established with Pinus radiata D. Don in Galicia (NW Spain) through the Yield-SAFE model to calculate the LER        The Yield-SAFE is a biophysical model to predict the long-term production according to light and water availability in exclusively agricultural and forest systems and also in agroforestry systems in which woody vegetation, crops and/or livestock are integrated on the same area of land   The productivity estimated with the Yield-SAFE model can be used to determine the Land Equivalent Ratio (LER). The LER allows compare the productivity of an agroforestry system with the productivity of a monoculture system    Yield-SAFE model   OBJECTIVE    CliPick tool (climate daily data)   i) Forest systems established with Pinus radiata D. Don. It was simulated the management carried out in the yield tables for this tree species in Galicia    ii) Agricultural systems with a Dactylis glomerata L. pasture which was harvested three times in the spring and one time in autumn to replicate traditional practices in Galicia   iii) Silvopastoral system in which the pasture was combined with Pinus radiata D. Don established at 100 tree ha-1 to keep the land eligible for CAP support. It was simulated that the pasture was harvested three times in the spring and one time in autumn during the first ten years and then only one time in the spring and one time in the autumn because the pasture production decreases over time due to the shade generate by the trees   SIMULATIONS (Pasture Production and Stand Volume) LER =  pasture production in agroforestrypasture production in agricultural+stand volume in agroforestrystand volume in forestry At the end of this study the hypothetical silvopastoral system   produced 41% more than the exclusively forest and agricultural systems
