This book is about exploring both the potential and the limits of communication - of using communication both as a tool and as a way of articulating processes of development and social change, improving, everyday lives, and empowering people to influence their own lives and those of their fellow community members. The essence is communication. The dilemma is that communication will not solve every problem, although it can contribute in some ways to problemsolving - we just need to get better at knowing how. The discipline of communication for development is currently at a crossroad, and the approaches taken over the last few decades require serious rethinking. Technologies are evolving, societies are changing, globalization is impacting on everything - and communication for development is evolving and changing, too: as a tool as an approach and as a scientific sub-discipline of communication concerned with debates and issues relating to development and change in society. The aim of this book is to contribute to the critical reflection about how communication works in processes of change within the context of globalization.
