      abstract     = {Water-use efficiency is the amount of carbon assimilated
                      per water used by an ecosystem and a key indicator of
                      ecosystem functioning, but its variability in response to
                      climate change and droughts is not thoroughly understood.
                      Here, we investigated trends, drought response and drivers
                      of three water-use efficiency indices from 1995–2018 in
                      Europe with remote sensing data that considered long-term
                      environmental effects. We show that inherent water-use
                      efficiency decreased by $−4.2\%$ in Central Europe,
                      exhibiting threatened ecosystem functioning. In European
                      grasslands it increased by $+24.2\%,$ by regulated
                      transpiration and increased carbon assimilation. Further, we
                      highlight modulation of water-use efficiency drought
                      response by hydro-climate and the importance of adaptive
                      canopy conductance on ecosystem function. Our results imply
                      that decoupling carbon assimilation from canopy conductance
                      and efficient water management strategies could make the
                      difference between threatened and well-coping ecosystems
                      with ongoing climate change, and provide important insights
                      for land surface model development.},
