A woman in Liberia learned to plant sweet potatoes on mounds from her brother, who learned it at school. A father says he gets his ideas about corn from his son. That is the whole design behind what we do: we train the agriculture teacher, the students practise on a school demonstration farm, and the lesson goes home with them. A four-year randomized trial by Northwestern University found this route nearly three times as effective at getting adult farmers to adopt new practices as traditional extension programs, which may be why a farmer here can say the new way gave him fifteen bags of cassava from eleven lines. This week our team is in Liberia with 4-H Liberia training the next group of teachers. Follow along to see what comes home from school next.
