Tuesday Keynote: Keynote address- Risk and Resilience: What climate change means for the UK food system

Climate change is, and will continue to, impact the UK food system in a variety of ways, posing both challenges and opportunities. In this keynote address, Dr. Peter Falloon—Science Lead for Food Security at the UK Met Office—will explore the systemic risks and opportunities facing the UK food system as climate conditions evolve.

Drawing on his expertise in climate modelling, weather and climate data, and agri-environment systems, Dr. Falloon will outline how climate change is expected to affect the UK food system from farm to fork and considering domestic and international dimensions. He will present the latest climate projections and illustrate how data-driven adaptation planning is essential to building resilience.

What you’ll gain

  • Clarity on climate trends: An evidence-based overview of projected changes in climate and  extreme events, informed by Met Office climate data.
  • Understanding systemic vulnerabilities: Insights into how climate change will impact the UK food system and its activities, with a particular focus on extreme events.
  • Practical adaptation strategies: Approaches to building resilience, including integrating weather and climate forecasts into planning, design, and operational practices.
  • Opportunities for cross-sector collaboration: Emphasis on partnerships between climate scientists, engineers, policymakers, and industry leaders to drive innovation and mitigate risk.

Session 8c: Code of Practice - designing systems for rising ambient temperatures
Chair: Judith Evans

Higher heat levels will affect the ability of refrigeration systems to function. Recent work in the UK has identified that there are no comprehensive and widely agreed practices to ensure that refrigeration systems continue to operate as the climate changes. The workshop will provide information on a UK initiative lead by the IOR, IMechE, CIBSE, CCF and BSRIA to develop a Code of Practice to design, maintain and operate refrigeration systems as the climate warms. The workshop will:

  • Describe the background to the work and why this Code is important and why it is being developed.
  • Provide information on the draft Code.
  • Invite attendees to provide feedback and engage with the Code development.
