"This study reviews and analyses what has already been documented on the links between radio-based communication strategies and rural development outcomes, particularly with regards to smallholder farming and food security outcomes. The report explores best radio practices, including issues related to optimal formats, schedules, production qualities, and station management, based on 17 case studies from India, the Philippines, Tanzania, Mali, Malawi, Mozambique, Ghana, and South Africa. The key findings include: testimonials and jingles facilitate the best recall and comprehension of messages (Philippines); radio forums strengthen rural decision-making structures (Tanzania); radio programmes created by communities attract high listenership (Malawi); and farm radio is more effective when linked with new information and communication technologies (Ghana). The research also identified some knowledge gaps: the lack of evaluation as an integrated element in radio campaign planning; the need to conduct regular audience surveys; the limited use of non-participatory effectiveness studies and the limited scope of evaluations focusing on the impact of just one or two programmes."
