'Drawing together the findings of a decade of research, this book presents numerous lessons learned for targeting, designing, managing and monitoring agricultural PES. The contributors apply a rigorous and skeptical scientific eye to the body of experience, describing failures as well as successes, and highlight challenges that have not yet been solved.' Sara J. Scherr, President, EcoAgriculture Partners'This book compiles years of research and policy implementation on ecosystem services in the Neotropics, from measurement to certification and payment. It is essential reading for anyone looking to analyze experience to date and to identify future directions and challenges for sustaining ecosystem services in agricultural landscapes.'
