This toolkit is designed to help development practitioners use interactive radio to create compelling radio programming. The toolkit does not assume that radio is always the most appropriate solution for disseminating information. Rather, given the presence of radio in much of the world, this toolkit aims to help practitioners develop a systematic approach to using interactive radio as one effective way of sharing information with their target audience.
