Nutritional yield and nutrient density indicators for global food systems

Summary

This paper, published in Global Environmental Change, proposes or evaluates indicators for measuring nutritional yield and nutrient density at the scale of global food systems. It likely argues that conventional productivity metrics such as caloric or biomass yield are insufficient to assess the nutritional quality of food production, and advances metrics that better capture the capacity of food systems to meet human micronutrient needs. The work is relevant to debates about sustainable food system transformation and the integration of nutrition into agricultural and environmental policy.

UK applicability

Although framed at the global scale, the indicator frameworks developed in this paper are likely applicable to UK food system assessment, particularly in the context of post-Brexit agricultural policy, the Environmental Land Management scheme, and efforts to align food production with public health goals.

Key measures

Nutritional yield (nutrients produced per unit area or input); nutrient density indices (nutrient content per unit food weight or energy); potentially land use efficiency metrics

Outcomes reported

The study likely develops and applies composite indicators of nutritional yield and nutrient density to assess how well different food systems deliver nutrients per unit of land, input, or output. It may compare performance across crops, regions, or dietary patterns using standardised metrics.
