Extension Worker (VEW) can be working with eight groups of farmers, each with 40-150 farmers, or a total of 300-1,200 farmers. A fully trained Agricultural Extension officer would be responsible for eight VEW, so would be overseeing extension activities of 2,500-10,000 farmers. In the absence of group organization, it would be difficult for an agent to reach effectively a fraction of these numbers. In the intensive cash- crop schemes, an agent normally serves only a few hundred farmers. Even in projects stressing agricultural extension via radio broadcasts, it appears that supplementing the radio programs with weekly group forums organized by a "monitor" added to the impact. When the monitor is backstopped by an agronomist, the effectiveness seems even higher.1 As suggested earlier, groups can also be utilized in the process of helping people to discover their own knowledge and power.2 The group may be for literacy training or grain storage (as suggested above) or may be shaped around general agricultural technology needs; it might be radio listening group or film making group. There are, of course, problems inherent in the notion of organizing groups. The theory of using groups generally assumes that the groups are characterized by an internal cohesion, a sense of mutual obligation, and a rough equality. It is presumed that because group actions are rational, it is rational for every individual to participate in the group. These pre- sumptions are frequently erroneous. 1Edgar G.
