  1. Swedish Hydrology Day 2014Welcome ! Georgia Destouni

  2. Main theme: Water and Energy Close relations Different perspectives Highlights

  3. Temperature Precipitation Latent heat flux Evapotranspiration Water flux & availability

  4. Land cover data Sweden van der Velde et al. (J Geophysical Res: Atmospheres, 2013) Data-givenETfor different land cover types Land cover developments drive changes in water& energyfluxes ET / P Energy useefficiency AET/PET ET / PET

  5. Temperature Precipitation Latent heat flux Evapotranspiration Waterusefor energy & foodproduction Water flux & availability

  6. Hydroclimaticshifts driven by human water useforfood and energyproduction Destouni et al. (Nature ClimateChange, 2013) T P Start 20thcentury End 20thcentury

  7. Solid lines: ETwb=P-R Agricultural catchments Hydropowercatchments Destouni et al. (Nature ClimateChange, 2013) Unregulatedcatchments

  8. Temporal Rvariability Unregulatedcatchments – fluctuationsbut no shifts in CV(R) Hydropowercatchments – decreasedCV(R) Agricultural catchments – increasedCV(R) Destouni et al. (Nature ClimateChange, 2013)

  9. Integratedframeworktoassessclimate, land-use, energy and waterstrategies (CLEWs) Howells et al. (Nature Climate Change, 2013) Water, energy and land systems arehighlyintegrated, and anyassessmentoftheseresourcesshouldtreatthem as such
