From the reviews: "This book encompasses three main topics: Framing the Issue of Sustainability, Sustainable Pathways and Sustainable Metrics. ... This book should serve as a resource for science-based knowledge for future researchers and policy-makers, and as a catalyst for collaboration among interested experts from various disciplines. In this sense, the effort of this book may indeed be significant." (Giancarlo Barbiroli, International Journal of Environment and Pollution, July, 2006)
