Extended Data Fig. 1: The effects of total harvested area on national yield stability and its main determinants.
From: Larger nations benefit more than smaller nations from the stabilizing effects of crop diversity
The effects of total harvested area on (a) national yield stability, (b) national average crop stability, (c) national crop asynchrony, (d) effective crop diversity, (e) precipitation instability, and (f) temperature instability. Black lines with grey shades represent linear model fits and 95% confidence intervals. Solid lines show significant relationships (P < 0.05); dashed lines show nonsignificant relationships. Linear model results are shown in each panel. Sample size (n) is 673. Two-sided t-test was used for statistical testing. ***P < 0.001; **P < 0.01; *P < 0.05.
