Situations and conditions in which Peace Corps volunteers who are ABG's (A.B. generalists, or individuals with a bachelor of arts in English, liberal arts, or social science) are effective in agriculture and the factors which contribute to the ABG's effectiveness were analyzed and assessed in the study. Methodology included an analysis of training and service completion of over 1,600 volunteers, an analysis of costs and cost-effectiveness, an opinion survey of volunteers currently working in agriculture, and field research in 11 Peace Corps countries. Findings indicate the following: ABG's, in general, are effective in that their service record (duration, achievements, etc.) is comparable to other volunteers working in agriculture. They are cost-effective in that their cost per month of service is the lowest in relation to the other skills used in agriculture. ABG's who are specifically trained to perform well-defined, challenging jobs, who are supported with adequate supplies and equipment, and who are given proper supervision perform effectively in agriculture. It is concluded that there is a supply of ABG's and a demand for trained manpower to develop agriculture; it is the responsibility of the peace Corps to identify the demand which meets the known supply and to program accordingly.
