Query: Are the results of the groundwater model robust?   De Graaf et al. (2019) suggest that groundwater pumping will bring 42--79\%
of worldwide watersheds close to environmental exhaustion by 2050. We are
skeptical of these figures due to several non-unique assumptions behind the
calculation of irrigation water demands and the perfunctory exploration of the
model's uncertainty space. Their sensitivity analysis reveals a widespread lack
of elementary concepts of design of experiments among modellers, and can not be
taken as a proof that their conclusions are robust.
