Agricultural land currently covers 37% of the world's land surface,1 and most projections indicate that there will be future increases.2 Since crops represent a significant proportion of this anthropogenically altered land cover, they have substantial potential as a platform for land surface based climate solutions. Cropland has multiple ways in which it could be used to help mitigate climate warming, including conventional mitigation (reducing carbon emissions from the agricultural sector),3 as a source for carbon capture and storage (CCS) geoengineering4 (for instance using bio-char)5 and as a way of managing surface net solar radiation (surface...
