This study is a synthesis of the Collaborative Study of Cassava in Africa (COSCA), that was carried out from 1989 to 1997 by gathering primary data from 281 villages in six countries: the Congo, the Cote d'Ivoire, Ghana, Nigeria, Tanzania and Uganda. Designed as a follow-up to William O. Jones’s classic 1959 work, Manioc in Africa , this book will be of interest to African policy makers, international donor agencies and food policy analysts.
