With Professor Paul Behrens and Dr Juan Pablo Cordero, chaired by Professor Sarah Bridle

Many decisions about our food system are being made based on data and computer models, including how we should respond to climate change, what subsidies governments should provide, and what changes supermarkets should make. But how do we know if these numbers and models are reliable? When should we trust them, and when should we be asking more questions?

Transparency is often suggested as a solution, but what would that actually look like in practice? Can we imagine a world where researchers, policymakers, and practitioners share their data and models openly -- combining their insights to create something more powerful than any one group could achieve alone?

Our panel brings together expertise from energy systems, astrophysics, and food system modelling. They'll share how they build computer models to understand our food system, the practical challenges they face, and what they've learned about using these tools to inform real-world decisions. Expect an honest conversation about the potential and the pitfalls.
