摘要：Drawing on a series of technology adoption studies carried out by the International Maize and Wheat Improvement Center (CIMMYT) in collaboration with national agricultural research systems in Eastern Africa during 1996-98, this paper suggests alternative approaches for designing technology adoption studies to obtain as much useful information as possible. It describes the Eastern African studies and summarizes specific lessons learned, asks what can be learned from farm-level studies in a few communities, explores generic limitations of micro studies and a range of problems and issues faced in carrying out such studies, addresses challenges that arise in trying to put together a set of compatible micro studies, and lists overall conclusions and specific recommendations.
