Data for a study of learning within farmers' cooperatives were collected by interviewing members of 25 such cooperatives in Imo State of Nigeria. Information was also gathered from a literature review and interviews with Nigerian government officials who worked closely with cooperatives. Three types of cooperative associations were identified: those where members own and operate communal farms as a group, cooperative societies that facilitate the business of members who remain independent farmers, and a mixture of these two, where a cooperative society operates communal farms and members operate their private farms as well. Learning activities are mostly informal. Members learn through observation and participation. By participating in planning and execution of projects, members develop planning, production, marketing, leadership, public relation, and community development skills. Although extension agents and cooperative inspectors play significant roles in the educational process, members are primarily their own teachers. Most educational activities are carried out according to plans based on needs and directions aimed at correcting weaknesses. Major problems of farmer cooperatives relate to conflicts of interest, poor member education, and lack of storage and processing facilities. Cooperatives contribute positively to the education, business, income, and well-being of their members. (YLB)
