Sex roles in the Nigerian Tiv farm household and the differential impacts of development projects

Data are drawn from an agricultural project in Central Nigeria, and focus on one ethnic group, the Tiv. The paper provides a quantitative comparison between the projected impacts of a development project using a conventional planning methodology based on the aggregated farm household and one using the proposed methodology in which project impacts are disaggregated by sex. It finds that a consideration of sex role differences helps to identify obstacles and flexibilities that are not anticipated by conventional analysis but which can influence farmers" decisions to adopt new technologies. Appended are reports covering labor requirements for 10 crops on a typical farm, the division of labor in staple crop production, net returns by crop, farm labor profiles by crop, and a 46-item bibliography (1954-81).
