The document discusses different pathways for disseminating agroforestry technologies in Western Tanzania that were used as part of a scaling up strategy. It finds that using farmer-trainers who have experience adopting the technologies themselves is the most effective approach. Over 70% of farmers identified farmer-trainers as a more useful source of information than agricultural extension agents. Establishing a research and dissemination network that includes farmers, researchers, and organizations also helped scale up the technologies by facilitating knowledge sharing and providing feedback to refine the approaches. While local leaders could help disseminate the technologies, most farmers were opposed to them playing an active extension role.
