Community radio can be an effective tool for improving food security and climate adaptation among subsistence farmers in Malawi. The African Farm Radio Research Initiative partnered with Dzimwe Community Radio to conduct participatory radio campaigns promoting improved farming practices like hybrid maize varieties. Monitoring found the campaigns significantly increased adoption rates of the new technologies and helped farmers improve food security and health. Lessons from this success suggest community radio is well-suited to disseminating climate adaptation strategies to rural smallholder farmers in Malawi and beyond.
