Francisco Sagasti examines the complex interactions between science, technology and development through history, explores how capabilities in these areas are created in different countries and places the role of international co-operation in perspective. The book then introduces a 'science and technology capability index' to rank countries, analyses the policy implications of the place they occupy, and summarizes the experience of developing countries in formulating science and technology policies. It concludes with a review of important lessons for the future. This highly innovative and original work will strongly appeal to academics, policymakers, development practitioners and students interested in the role of knowledge and innovation in contemporary society, and in the disparities between developed and developing countries.
