TECHNOLOGY CHANGE AS AN INSTRUMENT IN AGRICULTURAL DEVELOPMENT

The introduction of new technology into agriculture is a central feature of development schemes, but is regularly criticised because of its distributive effects. Technology change is unavoidably biased, however, and cannot easily be used to serve specific distribution objectives. Ex post studies do not necessarily guide the appropriate choice of technology as they rarely offer causal explanations. Predicting the consequences of innovation is hampered by the narrowness of established economic models and the conceptual indefiniteness of technology as a variable in those models. In the absence of a wider system framework, technology for development is selected according to more general guides. These emphasise either the primacy of output objectives or advocate technology forms presumed appropriate to distribution objectives. Neither adequately substitutes for a broad framework to guide the choice of technology as an instrument in development.
