This book is the outcome of a three-year project coordinated by a group of Swedish researchers and with collaborating scholars from Africa and Asia. It provides a comparative study between Asian agricultural development during the Green Revolution in food production and the current problematic agricultural situation in sub-Saharan Africa. Case studies of eight African and eight Asian countries (focusing on the early part of the Green Revolution) were carried out. Based on these studies the book presents a causal and explanatory model of Asian green revolutions and discusses why it has occurred in Asia, but not in Africa.
