The Global Challenges Research Fund (GCRF) is a £1.5 billion fund that supports researchers seeking to address challenges faced by developing countries and forms part of the UK’s Official Development Assistance (ODA). The GCRF addresses the United Nations Sustainable Development Goals. The British Academy runs programmes through the GCRF that are challenge-led and interdisciplinary. The Academy also has a strong emphasis through the GCRF on strengthening capacity for research and supporting equitable partnerships. This British Academy GCRF Policy Briefing Series aims to present the knowledge and insight derived from researchers working on the programmes funded by the GCRF.
