Increasing pragmatic and ethical concerns have been raised about the inadequacies of conventional approaches to agricultural research and extension worldwide and the lack of integrated efforts among researchers, extension educators, and users. This paper examines three models of these relationships: the diffusion or supply model; the induced innovation or demand model; and the synthesis triangular or supply/demand model. The triangular model builds and improves upon the previous models by focusing on the role of clients or users in the broadest sense (...) in creating a demand for science and extension education, as well as on the role of scientists and extension educators in creating a supply. The triangular model views the relationship as an interactive partnership in which research and extension education are conducted in response to client needs and demands expressed through negotiation, persuasion, and coercion involving all partners. To implement this model will require significant organizational and managerial changes as well as reorientation in the values and attitudes of researchers, extension educators, clients, and their organizations. The remainder of the paper presents a brief discussion of suggested strategies at the individual, institutional, regional, national, and international levels for enhancing this partnership in order to more effectively meet the future needs of our food system.
