UNRISD Classics is a set of three volumes—Social Policy and Inclusive Development, Gendered Dimensions of Development and Revisiting Sustainable Development—that bring together 50 selected essays from 50 years of UNRISD research. The contributions both highlight some of the Institute’s most influential and ground-breaking research and, through new introductions, demonstrate its relevance to today’s development debates. For the launch event, UNRISD invited a panel of dynamic speakers who engaged with the role of research in development policy and practice, and, more broadly, how ideas have influence.
