 Increased crop water

Possible Adaptations
 Alternative crop systems
 Increased irrigation
 Less groundwater

 Alternative water supplies

Increasing
evapotranspiration
Less snowfall
 Less replenishment
of glaciers and
smaller snowfields in
the mountains;
reduced river flow in
summer
 Less water available
directly from melting
snow in the dry season
 Drought management plans
 In the long term, less
water available from
melting ice
 Dams and reservoirs
 Fewer avalanches
 Irrigation efficiency
 More rockfalls
 Forestation
 Water sharing agreements
 Demand management
