Cassava is a major tropical tuber crop found throughout the tropics (India, Oceania, Africa and Latin America). Hitherto, there has been no single text covering all aspects of cassava biology, production and utilization. This book fills that gap, representing the first comprehensive research level overview of this main staple crop. Chapters are written by leading experts in this field from all continents. The book is suitable for those working and researching in cassava, in both developed and developing countries, as well as advanced students.

Horticulture Reviews is an open-ended, serial continuation series of review articles on research in commercial horticulture crops. This detailed analysis bridges the gap between the specialized researcher and the broader community of plant scientists.

This book is addressed to scientists, researchers, development specialists and policy makers who deal with natural resources and agriculture in the developing countries. It aims to (1) provide evidence of the impact of natural resource management research (NRMR) in the CGIAR; (2) establish a methodological foundation for impact assessments of NRMR; and (3) draw up a set of lessons for future impact assessment studies. The book consists of three main parts. Part I (chapters 1-3) provides the definitional, historical, and theoretical background for NRMR impact assessment in the CGIAR. Part II (chapters 4-11) presents the methods and results of seven case studies on the impact of NRMR projects carried out in the CGIAR. Two summary chapters (12 and13) are presented in part III. The book has a subject index.
