Food System Focus Would Help Solve Climate Change, Says Study

A paper in the journal Nature Food presents a new global food-system approach to climate-change research. The authors of the paper worked together on the Food Security chapter of the recent Intergovernmental Panel on Climate Change Special Report on Climate Change and Land, and their new approach brings together agricultural production, supply chains, and consumption. The authors propose that to respond to climate change via their food systems, countries can now move beyond traditional supply-side mitigation in crop and livestock production to encompass demand-side strategies, mainly dietary changes. The authors say the maximum amount of greenhouse gas reduction achievable through dietary change is eight billion metric tons of CO2 per year.
