First Published in 1991. This volume, containing the proceedings of a Conference organised by the Science, Technology and Development (STD) Forum in association with the Developing Countries Research Unit (DCRU), University of Strathclyde, on 9-10 April 1990, is a modest attempt at advancing awareness concerning Third World development mainly in two inter-related areas: (a) the problems faced in the advancement of science and technology in the Third World and (b) the use of scientific and technological knowledge for promoting sustainable development of these countries. Given the multi-disciplinary character of the Conference and, in particular, the variety of approaches adopted by the contributors, any attempt to synthesise the papers in a brief introduction is likely to be futile. The best that can be done is to introduce some of the papers in a brief review. But before that a few words on the objectives of the Conference, and in particular on the need for North-South Cooperation in science, technology and development, may be helpful.
