"This article focuses on a comparative analysis of community radio realities in two Lusophone African countries: Guinea-Bissau and Mozambique, whose local ield research refers to 2003, 2004, 2007 and 2009, respectively. It focuses on the tense relationship between political power and community radios through theoretical reviewing of two emerging concepts: “Communication for Development” and “Glocalization”. A comprehensive ground-breaking study, it aims at determining what role these media can play so as to build challenging and participative citizenship. It exposes the dangers threatening the sustainability of these tools of empowerment, on being deprived of viable institutional frameworks. The main objective is to identify similarities and differences, to discuss resulting issues and to investigate the feasibility of unifying criteria, formats and deinitions." (Abstract)
