Table 1.
The four dimensions, 27 domains and associated indicators used to build the metric of food system sustainability.
The 20 indicators indicated with an * are those which were eventually retained by [18] to calculate the 97 countries’ sustainability scores.

Food system sustainability score calculated for 97 countries and 20 indicators covering the four dimensions of food system: Environment, economic, social, and food security & nutrition.
The list of indicators used to build the map is provided in Table 1. Country individual scores are provided in S4 Table. Reprinted from [18] under a CC BY license, with permission from Scientific Data, original copyright 2019.

Spearman correlation tests between food system drivers and country food system sustainability scores.
Results ranked from the strongest to the weakest coefficients ρ (in absolute values). Drivers above the dotted line are those displayed in Fig 2.
Fig 2.
Relationship between country food system sustainability scores and key drivers.
Only drivers displaying a Spearman correlation coefficient (ρ) greater than 0.3 are shown: (a) change in merchandise and services trade; (b) change in population growth; (c) changes in agricultural area; (d) change in women employment in services; and (e) change in urban population. Trends (blue lines) estimated using linear or polynomials of degree 2 functions with a jacknife resampling method, are for illustration purpose only.
