The former Chair of the Scientific Group for the 2021 UN Food Systems Summit, lays out the importance of an inclusive process and multi-disciplinary scientific collaboration to meet the calls for food system transformation. Dr von Braun joins us to talk about his experience as Chair, what he sees as the successes of the summit, and what work remains to be done. We also discuss who should be involved in knowledge production and how, and we hear his thoughts on whether we should create an Intergovernmental Panel for Food (not unlike the IPCC) that would have the power to work towards scientific consensus on food system issues.
