We would like to express our sincere thanks to all those who contributed to the preparation of this report and to our separate centers, CIP and IFPRI, for their support of this research. We owe special appreciation to Rupert Best of the International Center for Tropical Agriculture (CIAT) for his comments and corrections on the various preliminary versions of this document and for supplying abundant source material on cassava in developing countries. Our gratitude goes as well to Mpoko Bokanga of the International Institute of Tropical Agriculture (IITA) for the very useful information on yam. We particularly wish to thank Luis Maldonado and Victor Suarez for their work on several of the historical statistical tables. Greg also would like to acknowledge Princess Ferguson for her editorial support in preparing the numerous preliminary drafts of this report and Jo Sears for her help in completing the final version. The authors also thank Uday Mohan for the technical editing of the manuscript and Rajul Pandya-Lorch, head of IFPRI's 2020 Vision initiative, for her constant encouragement and guidance throughout the process.

We are grateful to Roberta Gerpacio and Nicostrato Perez for their work on earlier versions of this report. They contributed both model runs and written documents. We would also like to thank C. M. Sourang of the International Fund for Agricultural Development for his permission to cite “A Global Development Strategy for Cassava” (by Plucknett, Phillips, and Kagbo) and “Global Cassava Market Study” (by dTp Studies), both of which are works in progress. Similarly we are grateful to Reinhardt Howeler at CIAT for his permission to cite “Strategic Environmental Assessment: An Assessment of the Impact of Smallholder Cassava Production and Processing on the Environment and Biodiversity” - a draft report by Howeler, Oates, and Costa Allem.
