This book presents the methodology and results of a three-year, eleven-country science-to-policy research project – Toward a Policy Model of Multifunctional Agriculture and Rural Development – undertaken between 2005 and 2008 and financed under the European Union''s Sixth Framework program.  It deals with an important contemporary policy issue: how best to ensure that an agriculturally-based policy can contribute to the development of rural regions. It tackles this problem in a number of different but complementary ways, primarily by the development of a unique and innovative dynamic systems model, POMMARD (a Policy Model of Multifunctional Agriculture and Rural Development).
