David Nabarro is currently Co-Director Institute of Global Health Innovation and Chair of Global Health, Imperial College London and Strategic Director, 4SD Foundation, Geneva, Switzerland. He serves as Special Envoy of World Health Organization Director-General for COVID-19 (since 2020) and Co-Lead, Food Workstream, UN Secretary General's Global Crisis Response Group (since 2022).

David has expertise and experience in people's food systems, nutrition, public health, climate action and sustainable development. He has worked in communities and hospitals, governments, civil society, universities and senior positions within the United Nations system until June 2017.

David's current emphasis is on connecting individuals and groups as they apply Living Systems approaches to complex challenges in human and planetary development, with a particular focus on equitable food systems and pandemic preparedness.

David's role in Food Systems Dialogues: In 2018, the World Economic Forum, EAT Foundation, the World Business Council for Sustainable Development and, later, the Food and Land Use Coalition and the Global Alliance for Improved Nutrition commissioned David and the 4SD team to devise and curate multi-stakeholder Dialogues in support of food systems transformation. 4SD then enhanced the approach and helped incorporate it into preparations for the 2021 United Nations Food Systems Summit. This led to food systems dialogues taking place in nearly 150 countries and the elaboration of transformation pathways which are now being pursued in more than 100 countries. Progress will be shared in a mid-2023 food systems stocktake and in forthcoming progress assessments on the 2030 Sustainable Development Agenda (and the SDGs).
