Figure 4

Predicted log10 food production (Mcal ha⁻¹ year⁻¹) from a linear model. Model terms are shown in Table 2. Predictions are classified by the main effects of the Scenario, Farm, and Timescale. Predictions are averaged over all levels of other terms included in the model. The error bar shows the approximate average LSD. Means within a single panel labelled with different letters indicates they are significantly different (P < 0.05, post-hoc Tukey test).
