Research methods in climate change adaptation
Methods
Vulnerability mapping
Social network analysis
Stakeholder-driven adaptation options
Scenario planning
Adaptive capacity: systems thinking
and bayesian modelling
Vulnerability
Identify vulnerable communities
Census and statistical data
Inform risk mapping
Social network analysis
Map community structure
Identify key stakeholders
Optimize stakeholder
engagement
Research-based pathways
Research-based policies
Scenario planning
Identify adaptation options with
stakeholders
Scenario planning: test
adaptation options under
different scenarios
Refine adaptation option pool
Adaptive capacity
Engage with stakeholders
Identify determinants of
adaptive capacity to implement
options
Use of systems thinking and
bayesian modeling
From research to practice: developing coastal hazard adaptation strategies
Decision making tool
Coastal hazard adaptation strategies (CHAS)
QLD Government $12M funding 2016-
2018
Local government $ matching
41 Local government areas eligible
Expert guidance, guidelines and tools
CHAS guidelines
1. Stakeholder engagement plan
2. Scoping of issues to be addressed
3. Coastal hazard mapping
4. Identification of system components
5. Risk mapping
6. Identification of adaptation options
7. Multi-criteria assessment and CBA
8. Trigger points for implementation, etc.
Stakeholder engagement plan
Scoping issues
• Coastal processes
• Ecosystems
• Buildings and infrastructure
• Socio-economics
• Selection of specific localities
Hazard mapping
Queensland Government maps:
Coastal erosion and storm tides
High or medium hazard areas
0.8 m sea level rise
1% AEP / 100 year ARI
GIS overlay to assets maps
Identification of system components
Coastal ecosystems and parks
Buildings and infrastructure
Planning instruments
Public services
Recreation, culture and
values
Risk = Probability x Consequences
Risk = Probability x Consequences
Identification of adaptation options
1. Regenerative options 1.1 Beach nourishment 1.2 Dune construction and regeneration
1.3 Riparian corridor restoration and generation
1.4 Wetland restoration
2. Coastal engineering options
2.1 Artificial reefs 2.2 Detached breakwaters
2.3 Groynes and artificial headlands 2.4 Sea dykes
2.5 Seawalls 2.6 Storm surge barriers
3. Coastal settlement design options
3.1 Building retrofitting and improved design
3.2 Flood-resilient public infrastructure 3.3 Raise land levels
4. Planning options 4.1 Development setbacks
4.2 Land buy-back 4.3 Land swap
4.4 Land-use planning
