Decision basis and risk assessment due to climate change
• Spatial planning
• Precautionary measures
• Adaptation activities
• New possibilities

BalticClimate
Decision basis -natural risk management
Problem analysis and risk assessment
Decision basis for adaptation measures
Basis for spatial planning
Information gathering• Geology/geotechnical prerequisites• Protecting structures• Current and historical hazards• Assets (economic, environmental etc.)
Analysis incl climate change• Potential hazards• Potential risk areas
• Need for precautionary measures• Constraints for development• Natural hazards ”hot spots”
• Protective measures• Adaptation activities
BalticClimate
Climate adaptation – build environment
- identify vulnerability and risk levels
- adaptation and reinforcement
- permanent and/or temporary reinforcements

BalticClimate
Climate change and spatial planning
- planning conditions (soil and water)
- local and regional perspective
- long term planning focus
- precautionary measures
- security and flexibility
