so obvious. If tractors, threshers or other machines are sensible, group purchase and utilization can assure that benefits are widely shared and can reduce the likelihood that the first individual purchaser of machines will use his new profits to buy out his neighbors, who can no longer com- pete with him. If improvements in livestock management are suggested -- such as regulated grazing and breeding or control of communicable livestock diseases -- cooperative action by many farmers is needed. Group action by farmers may also be useful in controlling plant diseases and pests, in- cluding rodents. For improvements in general sanitation, which are crucial for improved human health, some collective actions (or at least restraints) are needed. For these types of activities and others, group organization can be very helpful, and extension work can both be facilitated by groups and help form the groups. At a broader, more political level, when farmers are organized in groups, they are more likely to exercise power over the personnel and policies of the extension system. When organized, the farmers are better able to fund local extension activities and to participate in local experiments by contributing land and their own knowledge. At the broadest, philosophical level, the animation rurale projects in former French colonies are "based on the belief that man is by nature a social animal who finds individual fulfillment through participating in activities which lead to the development of his community." This view has its roots in both Catholic humanism and African socialism.
