This book is a must for practitioners in science and technology policy in developing countries, with a rich array of case studies in the continuing search for demand driven policies which can tap into globalized knowledge production. This book is about changing social relationships and the authors focus on the question of what social relations make for successful science and technology policies. In particular, the various chapters illustrate what happens at different social interfaces, such as between policy makers and researchers, and between the users and producers of knowledge. In other words, they are interested in the knowledge networks that are emerging between the many different actors involved in the development of science and technology.
