ClimGrassHydro: Ecohydrology of mountain grassland under global change: mechanisms and consequences

Funded by the ESS-program of the Austrian Academy of Sciences (ÖAW), 2019-2022

ClimGrass design

ClimGrassHydro aims

  • to understand the individual and combined effects of multiple levels of climate warming, elevated CO2 and severe drought on the ecohydrology of managed montane grassland,
  • to quantify the implications of ecohydrological responses for agricultural yield and water yield, and
  • to develop a platform for transdisciplinary exchange and integration of knowledge with climate economics and stakeholders from the agricultural and energy sectors for identifying vulnerabilities and possibilities for climate-smart adaptation

ClimGrassHydro is based at a unique experimental facility at the agricultural research station AREC Raumberg-Gumpenstein, which includes 54 plots arranged in a response surface design for testing the multilevel effects of warming and elevated CO2, combined with a factorial design testing effects of extreme droughts under current and future climate conditions.
