Rainfall recycling needs to be considered in defining limits to the world’s green water resources
Open accessAbstract
In PNAS, Schyns et al.’s (1) analysis of the limits to the world’s green water resources starts from the commonly made assumption that rainfall is an independent, exogenously determined variable, not influenced by anthropogenic land cover change. An increasing body of research now suggests that this is incorrect (2). It matters where rainfall comes from, and where evapotranspiration (ET) goes to. While blue and green water as distinct hydrologic concepts advance scientific discussion, setting potential limits to green water use requires an understanding of rainfall recycling across the globe. Portraying water management as a green water versus blue water allocation issue avoids the up- and downwind dynamics of the … [↵][1]1To whom correspondence should be addressed.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
