Extended Data Fig. 9: Observational constraint for the blue water tradeoff.
From: Mid-latitude freshwater availability reduced by projected vegetation responses to climate change
Constraining the runoff loss to vegetation (blue water tradeoff, BWT) and changes in runoff, ∆Q. Because ∆C/ET dominates changes in C/P (see Fig. S8), we show the relationship between historical (observed period, 1982–2014) C/ET and future C/P in (a) across models and regions. For each region, we show the observational range ( + /− 1σ) of C/ET, derived from the sum of interception and transpiration from Wei et al. GRL (2017) as colored bars mapping to the x-axis, with colors corresponding to the inset map. (b) Bar plot of unconstrained (raw) versus constrained BWT and ∆Q for each region. Whiskers show 1 standard error of the mean.
