Arguing that widespread changes in human attitude and behaviour patterns are central to ensuring a more secure and sustainable future on earth, this book focuses on communication processes in development. The authors show how communication can be used to mobilize societies, to facilitate democratic and participatory decision-making, and to help people acquire new knowledge and skills. Among the issues explored are: social mobilization worldwide for child immunization; communication as a means of facilitating rapid advances in family planning; and the use of video to enable peasant farmers to participate in their own development. The book should be of interest to those working in development, both as practitioners and theorists, and to those concerned with politics and society in the developing world.
