The purpose of this article is to highlight the key developmental role, but not always perceived at its fair value, that radio plays at the national and more precisely at the local level. Radio is a means of communication easily accessible to most people, as well in rural area as in urban area. As such, in particular socio-political contexts, it plays a leading role despite the pervasiveness of television and the Internet that disrupt the current media world. The west of the Ivory Coast that was one of the main centers of the military-political crisis in the country between 2002 and 2011 offers, through the Toulepleu department, an appropriate framework for assessing the role of the media in the socio-economic development after this crisis. A number of radio stations available in this region allow for an analysis of the issue. The results obtained through field studies and participating observations do show the key role that radio plays in national reconciliation and awareness politics to other socio-economic development issues.
