"The authors present six local and independent radio stations from Africa - community radio stations, and commercial and NGO run radio stations with strong community participation - showcasing good practices for sustainability, defined as "ability of a radio station to maintain a good quality developmental broadcasting service over a period of time." Asking the question, what is it that needs to be sustained? they offer a holistic view on sustainability by examining how a radio station is embedded in its geographic, economic, infrastructural, social, linguistic and cultural context. Furthermore, the case studies consider the broadcasting environment, programme schedules, management structures and sources of income of the radio stations. Particular attention is paid to the community engagement of the radio stations and to the causes for active community involvement." (Commbox-JF)
