This book presents technical discussions of various AFS, economic theories, and methodologies applied to assess these systems in order to provide insight for policy and management. In doing so, the book covers 13 countries from all five continents of the world. Although the results presentd in each chapter are based on specific case study data, they can be applied broadly because they are derived through appropriate rigorous quantitative aproaches. This volume is primarily intended for upper division undergraduate and graduate students, as well as agroforestry and rural development professionals across the world. In addition, this book can be a significant new reference tool for resource conomists, rural sociologists, and other social scientists interested in rigorous, quantitative analysis of agroforestry systems. Finally, this text is intended to provide valuable insights for policy makers and representatives of government and non-government agencies dealing with agroforestry practices in bothy developing and developed countries.
