Summary
This Nature paper by Springmann and colleagues presents a systems-level analysis of how to reconcile food production with planetary boundaries whilst ensuring nutritional adequacy. The authors modelled multiple pathways—combining agricultural intensification, food waste reduction, and shifts towards plant-rich diets—to identify feasible scenarios for keeping the global food system within critical environmental limits. The work synthesises evidence across soil, water, climate and nutrition domains to inform food system transformation.
UK applicability
The dietary and agricultural recommendations are relevant to UK policy, particularly regarding the National Food Strategy and Net Zero ambitions. However, the global scope means UK-specific implementation would require adaptation to domestic land availability, production capacity and consumer contexts.
Key measures
Greenhouse gas emissions, land use, freshwater consumption, nitrogen and phosphorus use; nutritional adequacy across food groups and dietary scenarios
Outcomes reported
The study assessed options for aligning global food systems with environmental boundaries (greenhouse gas emissions, land use, freshwater, nitrogen and phosphorus pollution) whilst meeting nutritional requirements for a growing population.
