Food systems boundaries are currently poorly defined

Summary

Behrens and Poore argue in this Nature Food commentary that food systems research and policy currently lack consistent, clearly defined boundaries—a foundational problem that limits the rigour and comparability of food systems science. The authors highlight how variable boundary definitions across studies undermine efforts to assess environmental, nutritional, and social impacts coherently. This work suggests that establishing standardised boundaries is essential for advancing food systems research and informing evidence-based policy.

UK applicability

UK food policy and agricultural research would benefit from aligning boundary definitions in food systems assessment, particularly for environmental labelling, sustainability reporting, and supply chain governance. Clear boundaries are needed to support devolved food strategies across England, Scotland, Wales, and Northern Ireland.

Key measures

Definitional approaches to food system boundaries across literature and policy; scope and consistency of boundary-setting in food systems research

Outcomes reported

The paper examines how food system boundaries are defined across different research and policy contexts, identifying inconsistencies and gaps in current conceptual frameworks. It likely assesses the implications of these boundary definitions for food systems analysis and sustainability assessment.
