Current policies
Climate change water scarcity and droughts
Policy shift and waterplan 2009
Policy development on water scarcity and droughts
1976 Most severe water scarcity and droughts event in Dutch history
1985 Policy for present water scarcity and drought management
2003 Renewed attention for water scarcity and droughts
2009 National Waterplan

ConclusionsConclusions
• Fresh water availability under pressure
• Before 2050 exceeding critical chloride concentrations
• Summer 2003 will be normal in 2100
• National water balance will be negative in 2100

Adaptation to Climate Change
Strategies
• Water users anticipate on water scarcity
• Measures in water system
• Desalination
• Retaining and storing fresh water in winter
