The book examines research-extension-farmers linkage in relation to participatory finger millet technology development and delivery, and the identification of factors influencing linkages in North West Ethiopia due to the fact that the present research-extension-farmers linkage scenario in Ethiopia in general has been inefficient and ineffective in achieving the prescribed goal of food security and improving the quality of life of farmers. However, little research attempts have been made in blending the various aspects of technology development and transfer with research-extension-farmers linkages. This book, therefore, provides critical success factors for effective research-extension-farmers linkage that foster demand driven, multi stakeholder, grouped based technology generation and transfer, and should be especially useful to researchers, extension agents, farmers and relevant actors who may use the success factors for sound technology development and transfer efforts. It also raises awareness to policy makers on the importance of linkages and to design linkage policies that promote system perspectives with transparent and agreed-upon linkage strategies.
