The book focused on maize value chains in the South Achefer and Jabitehnan districts of the West Gojjam zone of Ethiopia. The main objectives of the study were to map and identify the actors of the value chains, the structure of costs and marketing margin among them and to identify the determinants of farmers' participation decision and marketed volume in the study areas. In this study, both primary and secondary data were used. Producers, collectors, wholesalers, and retailers were found to be important actors in the maize value chain. Value chain governance was studied based on control oversupply, contractual agreement, quality and level of competition.
