Arguing that widespread changes in human attitude and behavior patterns are central to ensuring a more secure and sustainable future on earth, this book focuses on communication processes in development. Colin Fraser and Sonia Restrepo-Estrada, pioneers in the use of communication techniques and media in developmental work, 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.
