This document summarizes the Digital Green agricultural extension model which uses locally produced videos shown by local mediators to disseminate information to farmers. Key points: - Digital Green shows short videos on farming best practices produced by and featuring local farmers. This helps overcome issues like illiteracy and lack of access to experts. - Early experiments showed Digital Green was over 7 times more effective at increasing adoptions of new practices than traditional extension methods and cost 10 times less per adoption. - The model scales through a network of local mediators who screen the videos on a rotating basis in villages and facilitate discussions to support farmers. - Over 2500 videos have been produced on a range of topics indexed by location,

Rough “storyboarding”
– Repetitive pattern; easy to
learn
– Minimize post-production
Local farmers on their own fields
– Reduce perception of
