our meta-analysis suggests that digital interventions, on average, led to a 23 % increase in the adoption of fertilizer use among farmers (95 % confidence interval [CI], +6 % to +40 %)
Contexto
What changed: Delivery of agricultural advisory services and recommendations via digital channels such as video, SMS, and phone calls. Comparison: Control farmers who did not receive the digital service (status quo or traditional extension). Limits: Based on only nine studies across four countries, showing substantial heterogeneity in effect sizes across contexts and modalities.
