Greenhouse Strategy Action 5.5
Climate Change Vulnerability Assessment South
West WA
An integrated global climate change impact and
assessment strategy for the south west of WA will
be prepared through collaborative action by the
AGO, the State Government, local governments,
stakeholders and the public.
3

Why AGO involvement?
to provide both a framework for adaptation
in the south west of WA, but also to develop
techniques for regional climate responses in
other regions of Australia and overseas.
4

SW WA one of three nationally identified
priority regions for integrated assessment of
climate change vulnerability
Why AGO involvement?

• Coastal populations industry
• Agriculture
• Biodiversity
• Water supply
• Tourism
• Forestry
• Fisheries

What is an integrated assessment?
Climate Change Vulnerability Assessment South

How do you do one?
7

Integrated assessment
How do you do one?
a social process in which expert knowledge is
organised, evaluated, integrated and presented to
inform policy and other decisions.
8

Integrated?
How do you do one?
Multi-sectoral What not to include? Cross-sectora
l Drivers? Conflicts? Opportunities?
9
What is the best CSIRO advice in 2005?
Under the most optimistic future greenhouse
gases scenarios, significant warming and
decreased rainfall is projected for SW WA.
10
Climate change or global change / CO2
increase
11

• Differential sectoral vulnerability?
• 15 decrease in SW WA rainfall in the mid-70s
• crop yields increased.
• stream flow decreased by 50 -gt Perth is already
  water constrained.

How does God invest in biodiversity?
What lives?
What dies?

• What is our regional planning objective?
• business liquidation?
• speculation?
• investment?

14
Secondary effects through other factors?

• Storms, wind?
• Lightning?
• Fire?
• Pest infestations?
• Species invasions?
• Salinity impacts?
• Impacts to overseas producers or markets?

credible, salient and legitimate
17

• Critical features of recommendations
• Good scientific basis

Critical features of process
18

• Historical sectoral review

Stage One What can we learn from SW WA climate
change?
2. public engagement
19

• Stage One
• Report on experience of climate change in SW WA
  draft by mid 2006 final by Oct 2006
• Plan for Stage Two March 2006
• Climate scenario needs
• Consultation processes
• Analytical techniques
• How to integrate sectors
• Management and governance
• Partnerships localities / region

20

• What experience
• Was there any apparent capacity to have
  predicted the change in climate?
• When was the change perceived?
• When was there a overt response to the change
  per se.
• What was the nature of the response Control?
  Adaptation? ?
• What characteristics indicate an effective
  response?

21

• Stage Two
• When climate is a variable or changing factor
• What are the sectoral vulnerabilities /
  opportunities?
• What are the cross-sectoral conflicts,
  opportunities and drivers?
• What will be the key decisions?
• What are the options locally, regionally?
• What policy tools would be most effective?
