Figure 2

The option space (green cells) results from the combination of four yield variants, five cropland expansion variants, two variants of the feed basis for livestock at the supply side (lines) and five human diet variants combined with three variants of the origin of livestock products at the demand side (columns). Each cell in the option space represents a scenario. Scenarios affected by cropland limitations represent cases where the global demand for cropland products exceeds global supply by more than 5% and scenarios affected by grazing limitations when global grazing intensity exceeds ecological thresholds. ‘Probably feasible’ are scenarios for which demand and supply differ by <5%. *For the VEGAN diet, the source of livestock products is not relevant.
