INTERPAKS, In: G.E. Jones and M.J. Rolls (eds.), Progress in rural extension and community development. Vol. 1, Extension and relative advantage in rural development. Chicester, U.K.: John Wiley, 1982. p. 87-115., In many developing nations, serious efforts are being made to develop agricultural extension services into systems which can serve the broad masses of small agricultural producers, instead of only a few high-access farmers. Objectives have shifted to providing income-generating opportunities to small farmers; to increasing equity in rural areas; to broaden integrated rural development; or to organize rural people so as to allow them to carry their own development. Discusses the elements of the extension process. When extension objectives change, other elements must also change because the elements form an interconnected whole. Aims to systematically explore the implications of a change in extension objectives for the other elements of the process.
