Impact of Farmer Field Schools on Agricultural Productivity and Poverty in East Africa

Farmer field schools (FFSs) are a popular education and extension approach worldwide. Such schools use experiential learning and a group approach to facilitate farmers in making decisions, solving problems, and learning new techniques. However, there is limited or conflicting evidence as to their effect on productivity and poverty, especially in East Africa. This study is unique in that it uses a longitudinal impact evaluation (difference in difference approach) with quasi-experimental methods (propensity score matching and covariate matching) together with qualitative approaches to provide rigorous evidence to policymakers and other stakeholders on an FFS project in Kenya, Tanzania, and Uganda. The study provides evidence on participation in FFSs and on the effects of FFSs on various outcomes. The study found that younger farmers who belong to other groups, such as savings and credit groups, tended to participate in field schools. Females made up 50 percent of FFS membership. Reasons for not joining an FFS included lack of time and information. FFSs were shown to be especially beneficial to women, people with low literacy levels, and farmers with medium-size land holdings. FFS participants had significant differences in outcomes with respect to value of crops produced per acre, livestock value gain per capita, and agricultural income per capita. FFSs had a greater impact on crop productivity for those in the middle land area (land poverty) tercile. Participation in FFSs increased income by 61 percent when pooling the three countries. FFSs improved income and productivity overall, but differences were seen at the country level. Participation in FFSs led to increased production, productivity, and income in nearly all cases: Kenya, Tanzania, and at the project level (all three countries combined). The most significant change was seen in Kenya for crops (80 percent increase) and in Tanzania for agricultural income (more than 100 percent increase). A lack of significant increases in Uganda was likely due to Uganda's National Agricultural Advisory Services. When disaggregating by gender, however, female-headed households benefited significantly more than male-headed households in Uganda.
