Overview
• Adaptation assignment & spatial planning• A planner’s perspective• Tools to
• Quantify the assignment• Support planning and design
• Recent developments
Hazards and challenges
Climate is changing
Flooding (coastal, fluvial, pluvial, groundwater)
Drought
Heat stress

The planning process
Tiered approachThree steps:1: Vulnerability scan2: Strategy to reduce vulnerability3: Select set of adaptation measures

Vital and vulnerable objects, networks
• Power• Telecom• Hospitals• Evacuation routes• Elderly homes• Chemical plants• … … …
vulnerable people, animals andvital objects and networksrequire extra protection
CIrcle tool to analyse chain effects in vital infra
Tools• to identify the assignments• to support planning & design
Many, many options:
Lots of measures can be taken
Soft solutionsHard solutions
flexible and cost-effectiveless flexible, extra investment
more space but multi-functionalless space required
Blue-green solutions preferred over grey ones
Discuss and co-design solutionswith experts and stakeholders

Adaptation Support Tool
Dashboard
Ranked list of 62 blue, green andgrey adaptation measures
Dashboard
Dashboard with KPI’sbased on key figures, e.g.:
• Retention [m3]• Peak flow reduction (Treturn [yr])• Seasonal storage [m3]• Cooling effect [oC]• Groundwater recharge [mm/yr]• Water quality improvement:
• Nutrients (%)• HMs, PAHs, min. oil (%)• Bacteriological quality
• Costs (implementation and maintenance)• Benefits and ‘co-benefits’
Recent developments
First applications of these tools:
in the NetherlandsUtrecht, Dordrecht, …
abroadLondon, Beira, Oaxaca, …
