This Strategy sets out the priorities and themes of the United Nations Research Institute for Social Development over the period 2021–2025. It integrates research, communications, policy engagement, results and impact—and is calibrated against the fast-moving social, economic and political context as it impacts on development. It is the product of work with a wide range of stakeholders, and takes on board policy concerns and academic debates. We aim to fill identified knowledge gaps and also to anticipate fast-evolving social issues that are not yet in the mainstream. We are proud to have been doing this important work since 1963, and look forward to celebrating the 60th Anniversary of UNRISD in 2023, the mid-point of this Strategy period.
