Extended Data Fig. 2: Main determinants of national caloric yield stability.

From: National food production stabilized by crop diversity

Extended Data Fig. 2

af, Magnitude of the change in national yield stability as dependent on effective crop group diversity (a) and effective species diversity (d), precipitation instability (b, e) and irrigation (c, f). ac, Values of national yield stability are predictions from the multiple regression model using effective crop group diversity (Extended Data Table 2a). df, Values of national yield stability are predictions from the multiple regression model using effective crop species diversity (Extended Data Table 2b). Predicted values were back-transformed from log-transformation, calculated using the observed range of the three predictors and keeping all the other predictors at their mean values. The grey bands represent the regression 95% confidence interval.
