Bedru Balana and Olufemi Popoola co-organized an enumerator training for the baseline survey on 'Solar Dryer Intervention for Post-harvest Management' randomized control trial (RCT) study in Kano State, Nigeria. The four-day training of enumerators, field supervisors, and local project partner organization focused on the basics of RCT survey design, research ethics on human-subjects, consent form, roles and responsibilities of enumerators and field supervisors, survey protocol in social/economic study (dos and don'ts), and survey management using computer-assisted personal interviews (CAPI) (surveyCTO software). The training had 10 male and 12 female participants. As more research programs and projects are entering into experimental study design (including RCT), this training is very valuable to strengthening the capacity of young field workers and local organizations.
