The triple challenge: a stable climate, food security and space for nature – Food for thought: The role of diets in improving human and planetary health Meeting the dietary needs of a growing global population while averting dangerous climate change and safeguarding nature is one of the biggest challenges of our time. This session will feature a presentation on the potential benefits dietary shifts in over 100 countries could have on national-level human and environmental health, and how national dietary guidelines could be optimised to improve planetary health. There will be a panel discussion on how these shifts can be best achieved, with conservation, nutrition and farming experts looking at some of the solutions for a more sustainable and resilient food system.
