Agroforestry systems have been touted as sustainable production systems that alleviate many of the environmental problems associated with modern production systems. Are they indeed ecologically and economically sustainable? Using case studies from around the globe, this book highlights the potential of agroforestry systems to produce a broad range of commodities. In addition to addressing the biophysical and socioeconomic dimensions of producing traditional food, fodder and fiber crops, this volume examines the potential to integrate biomass crops, botanicals and ornamental plants into agroforestry practices. The book should be particularly useful to students, professionals, researchers and policy makers involved in natural resource management, agroforestry, and environmental management.
