A two-year cluster-randomised trial across 2,345 Ethiopian households found that supplementing government extension agents with locally filmed instructional videos raised farming-technique adoption by 6-7 percentage points, though crop yields did not rise.
Digital Green partners with Ethiopia's Ministry of Agriculture to supplement in-person extension work with short, locally filmed instructional videos (10-15 minutes) on specific farming practices such as row planting, precise seed spacing, and urea top-dressing. Government Development Agents (DAs) screen the videos to farmer groups alongside their normal extension visits.
Activities
A two-year cluster-randomised controlled trial run with J-PAL covered 2,345 households across 342 kebeles in 30 woredas in Amhara, Oromia, SNNP and Tigray.
Results
Video-mediated groups were 6 percentage points more likely to adopt at least one of the three target technologies in year one (from a 64% base) and 7 points more likely in year two. Farmers in video groups were also 17 percentage points more likely to report direct contact with a Development Agent. Despite the adoption gains, self-reported crop yields did not increase. A parallel arm inviting farmers' spouses to viewings improved women's knowledge scores but produced no additional adoption, since male household heads retained the final planting decision.
Conclusions
Digital Green reports the model has since been scaled to reach 438,488 farmers with 1,236 videos nationally, though this scale-up figure is self-reported by the implementing organisation rather than independently audited.
