The evaluation had the primary objective of measuring the impact of the FBO training program on farmers' farm productivity and crop income. It was based on a randomized phase-in approach, taking advantage of the fact that not all FBOs that were to be part of the program could be trained at the same time, and so implicit in the program design itself was some degree of phasing. At the core of the impact evaluation was a difference-in-difference approach designed to measure the difference in agricultural output between the treatment group (a collection of FBO members who received commercial trainings in 2008 and 2009) and the control group (a collection of FBO members who received commercial trainings a year later). The Farmer-Based Organization (FBO) Survey series is a collection of data designed to evaluate the impact of these trainings on farmers in Ghana. To aid the survey and enable the implementation of the difference-in-difference approach, the FBOs were divided into two batches and each farmer was to be interviewed twice: once at baseline and again after one year. Batch 1 treatment and control farmers were surveyed in November-December 2008 and again in February-April 2010. Batch 2 treatment and control farmers were surveyed in February-April 2010 and again in November 2010-January 2011. In total, approximately 6,000 farmers -- 3,000 in the treatment group and 3,000 in control group -- were surveyed.
Kind of Data
Sample survey data [ssd]
Unit of Analysis
The FBO Survey collected data on both farming individuals and farming households. The demographic information captured FBO members farmers' non-farm employment activities. Demographic information related to the individual included: sex, age, educational attainment (and literacy levels), religious affiliation, marital status and the relationship to the head of household. Descriptive information of the household included: age-sex composition, household size, sex of head of household, and household dependency ratios.
Anonymized dataset for public distribution
The FBO Survey targeted only farmers in rural Ghana who were also members of Farmer-Based Organizations (FBOs). Commercial trainings occurred in 30 districts across three (3) zones: the Northern Agriculture Zone (Northern Region), the Afram Basin Zone (Ashanti and Eastern regions), and the Southern Horticultural Belt (South-East Coastal Plains).

The Farmer-Based Organization (FBO) Survey covered farmers in three (3) Millennium Development Authority (MiDA) operational zones and the sample was selected in two (2) stages. In the first stage, FBOs were selected within each zone. MiDA made 600 FBOs available to the survey group, all of which were used in the sample. FBOs were randomly assigned to either receive the early trainings (Batch I) or the late trainings (Batch II). In the second stage, five (5) farmers were selected from each of the the 600 FBOs. Each batch contained approximately 3,000 farmers and 6,000 farmers in all were interviewed.
Deviations from the Sample Design
Researchers noted that there seemed to have been some level of contamination of the control group -- a problem that the farmers in the southern zone raised. There were two sources of this contamination. One was from the control farmers attending training sessions meant for the treatment group. The other source was engendered by the situation where farmers who got the training went around to their colleagues in the control group (who may have been part of some "original" groupings) and taught them what they had learned. Whereas the first was an implementation challenge, researchers noted, the second reflects positive spillovers of the training.
