6. Examples measures to mitigate the impact of drought
Campaign :
20% reduction in water use
Irrigation ban (issued by municipalities) during summer
Public awareness campaigns
New desalination plants up and running, Baltic Sea
Water pipeline from the mainland to island in Baltic Sea
Improved data and information (drought risk website, increased monitoring, new groundwater mapping using Sky TEM, etc)
New national drinking water council
Local and regional water plans
Initiative on methods for reducing runoff

7. Impact on status/ trends
GWBs
Mainly in quaternary deposits
Number: 3705
Cover 9 % of country area
Median size: 1,7 km2
Poor quant status: 9
Work in progress at local water authorities– no national results
-Good recovery in aquifers after abundant precipitation this autumn/winter
-Measures have been taken to reduce abstraction pressure (successful results reported)
Unclear change in number of GWBs in poor status due to the recent drought
New monitoring efforts in identified risk areas that faced drinking water shortage this summer
Poor quant. status
