Présentation de l'éditeur : Rice is a strategic and political crop in many African countries. The hikes in rice prices since 2007 have shown the vulnerability of many African countries that depend on the world market for rice imports and the need to boost Africa's domestic production. The purpose of this book is to provide a comprehensive overview of Africa's rice sector and ongoing rice research and development activities, and indicate priorities for action on how to realize Africa's Rice Promise', i.e. the notion that Africa has sufficient land and water resources to produce enough rice to feed its own population and, in the long term, generate export revenues. The critical challenge facing the African rice sector is to enhance performance in production, processing and marketing to respond to a major concern that needs to be turned into an opportunity: the growing demand for rice as a preferred staple. This book discusses challenges and opportunities related to: sustainably increasing rice production and rice productivity; enhancing rice quality and marketing; promoting conducive policies for smallholder and agribusiness development; and strengthening impact-oriented rice research, extension and knowledge management. The analyses and case studies presented in this book will be a valuable resource for researchers, development agents from public and private sectors, rice value- chain actors and policy makers concerned with Realizing Africa's Rice Promise.
