Fig. 2: Spatial and latitudinal changes in ΔY over contemporary growing area for wheat and maize.
From: Global irrigation contribution to wheat and maize yield

a Wheat, b maize. The left panel represents spatial distribution of reanalyzed ΔY. The right panel shows latitudinal distribution of ΔY for each one degree latitudinal band. The black curve shows ΔY estimated from the climate analog (CA) and the red curve shows ΔY estimated from the reanalysis, with shaded area indicates the range of uncertainty (1σ standard deviation across models).
