Questionnaires are designed in CSPRO and administered on laptops.
We conducted two follow-up surveys, a 2012 (midline) round, and a 2013 (endline), which form a panel of households and CFs in the study area. A baseline census survey was administered to all CFs in August 2010, before the district-level randomization. Figure 1 in the paper : 'Seeing is Believing? Evidence from an Extension Network Experiment' illustrates the timing of the surveys and CF trainings over the course of four years. Midline and endline surveys collected household demographics, individual and plot-level SLM adoption, and household production information for approximately 4,000 non-CF households in 200 communities (aldeias, that mostly overlap with Mozambique's enumeration areas) (Figure 2). A listing of households residing in each community was performed, from which we drew a random sample of 18 non CF-households per community. Our field work included five survey instruments: a household questionnaire; a household agricultural production questionnaire; a CF questionnaire; an extension agent questionnaire; and a community questionnaire. The household survey was also administered to CF households, in addition to the specic CF survey. The present analysis exploits the information from the household and CF surveys.
Both midline and endline surveys were conducted during the primary planting season in this region. In each survey round, households were visited twice: pre- and post-harvest. This is because SLM practices are most visible just after planting (pre-harvest, from February to April), while production data can only be obtained after harvest (May-June). Hence, all household surveys were administered during FebruaryApril, with the exception of the agricultural production module. The agricultural production (and CF, community, and extension agent) surveys were administered post-harvest during May and June in 2012 and June through August in 2013.
