Seven Food System Metrics of Sustainable Nutrition Security

This paper proposes a new food security assessment methodology based on the concept of sustainable nutrition security (SNS). The model defines seven metrics: (1) food nutrient adequacy; (2) ecosystem stability; (3) food affordability and availability; (4) sociocultural wellbeing; (5) food safety; (6) resilience; and (7) waste and loss reduction. Each of the metrics comprises multiple indicators that are combined to derive an overall score (0-100) for use in characterizing sustainable nutrition outcomes of food systems.
