Amount and location of changes in cropland for feed under different protein future scenarios. Percent of feed-based cropland spared (blues) or used (reds) to meet crop demands based on a comparison of business-as-usual (BAU) 2050 meat-based diet to seafood diet scenarios, from (A) mixed (freshwater and marine) aquaculture or (B) predominantly marine aquaculture. C depicts the total average land use (±SD) from crops for feed under each scenario and (D) displays the distribution of FAO regions that would spare more and use more in land use. Countries in gray do not change or are not applicable.
