Land cover developments drive changes in water &
energy fluxes
Land cover data Sweden

Latent heat flux
Evapotranspiration
Water flux & availability
Water use for energy & food production
Destouni et al. (Nature Climate Change, 2013)
Hydroclimatic shifts driven by human water use for food and energy production

Agricultural catchments
Hydropower catchments
Unregulated catchments
ETwb=P-RSolid lines:
Destouni et al. (Nature Climate Change, 2013)
Temporal R variability
Hydropower catchments – decreased CV(R)
Unregulated catchments – fluctuations but no shifts in CV(R)
Agricultural catchments – increased CV(R)

Integrated framework to assess climate, land-use, energy and water strategies (CLEWs)
Howells et al. (Nature Climate Change, 2013)
Water, energy and land systems are highly integrated, and any assessment of
these resources should treat them as such
