adaptation needs at 4°C compared to 2°C
(b) Proactive adaptation needed

Working towards adaptation planning
It all seems disempoweringly complex...
�Getting past impacts, vulnerability and adaptive capacity assessments, to adaptation decision pathways
– Not all decisions are the same
– Not all aspects of the future are equally uncertain
– There are systematic – There are systematic approaches!

Stafford Smith et al, PhilTransRoySoc 2011 (after Jones & McInnes 2004)
Sea level rise: 1m within 2080-2170
Uncertainty?Direction and magnitude ~sure, timing uncertain
• Temperature to at least 2°C, sea level rise to >1m,
non-polar ice sheet loss
Direction sure, magnitude uncertain
2150 2200 2250 2300
Direction sure, magnitude uncertain
• Atmospheric CO2, ocean acidification,
temperature extremes, total rainfall in some
regions, bushfire weather, rainfall extremes
Even direction uncertain
• Regional rainfall in some regions, cyclones, etc
Managing risk
Hallegatte (2009) Global Environmental Change 29: 240-7
(i) selecting ‘no-regret’ strategies that yield benefits even in absence of climate change (e.g. better disaster preparedness, ‘CAR’ principles))
(ii) favouring reversible and flexible options (e.g. real options, delaying development)
(iii) buying ‘safety margins’ in new investments (e.g. heavier dam foundations)
(iv) promoting soft adaptation strategies, including [a] long-term [perspective] (e.g. social networks, insurance, water demand reduction)
(v) reducing decision time horizons (e.g. shorter lifetime buildings)
Dessai & van de Sluijs (2007)
• 11 frameworks for decision-making; 12 tools for assessing uncertainty
Ranger et al. (2010)
• ‘Adaptation in the UK: a decision making process’
� Classify in terms of decision types and future change risks faced
1. Short lifetime decisions• Mainly adapt incrementally, watch out for thresholds
2. Long lifetime decisions (where most risk falls to government)1. Monotonic, ~certain to occur, timing unsure– E.g. 2°C, 1m sea level rise, more hot periods, more extremes, more CO2
– Plan for these, look for no regrets actions, use precautionary principle
2. Direction sure but extent unsure
Systematising responses
2. Direction sure but extent unsure– E.g. drying SW Australia and reduced water flows, fire risk in many areas
– Use risk management, ‘soft adaptations’ to delay expensive decisions (but prepare for these), ‘real options’ analysis
3. Even direction of response unsure– Robust decision-making, risk hedging against alternative futures, etc
3. And plan adaptation pathways, with critical decision-points• May include no action options, but deliberatively!

2. Not all threats are equal, nor equally uncertain
3. There are many approaches to managing risk

Systemic impacts of extreme events
Heatwaves
• Heatwaves in our southern cities are becoming more common and more intense events, with both chronic and acute impacts.
• Eg. SE Australia heatwave, 28-30th Jan 2009
– 374 premature deaths in SE Australia + morbidity
– Power blackouts to >500k buildings – one outage caused $70M load shed in 5h; Basslink overheatedcaused $70M load shed in 5h; Basslink overheated
– Transport disruptions (24% of Melbourne trains cancelled; $5M in fines)
– Damage to transport infrastructure
– Damage to fruit and vegetable growers; est. $10M’s
– Loss of economic activity: >$800M
• The frequency of such events is likely to at least triple in southern Australia by 2070
Queensland floods and cyclones 2010-11
Extreme events and productivity
Unexpected high-intensity rain and other weather affects transport, energy and mining infrastructure
Intensities expected to increase in many areas
Ensham Mine, Queensland, 2008• Production stopped for over a year• $millions in damage and costs
Yallourn, Victoria, 2007: • Excessive rainfall caused a massive landslip and flooding
• Caused serious power supply issues for Victoria
Pilbara, WA, 2006, 2009:• Cyclones in 2006 and excessive rain in 2009 closed the iron ore mines
Adaptation: cyclone building standards
Cyclone Yasi, 2011“JCU’s report shows that less than 3%of all post-1980s houses in the worst affected areas experienced significant roof damage, although more than 12%
of the pre-1980s housing inspected had significant roof damage.”
Cyclone Tracy, Darwin, 1974
had significant roof damage.”

1. Supply chains
• ~13% primary energy used in water supply system [US figures]
– major concern for water utilities
• Mining – despite major disruptions, evidence our industry is lagging behind
– ‘climate adaptation action’ - 40% (Canada) vs. 10% (Australia) vs. 45% LGAs (Australia)
2. Scheduling issues in mobilising capital investment
Is anyone managing the integrated risks?

2. Scheduling issues in mobilising capital investment
• Sydney Water’s $30bn assets
• E.g. roads
3. Coincident events
• Same place, multiple times; same time, multiple places; same budget cycle
Baynes et al, Climate Adaptation Flagship , 2012
1. Adaptation modelling should be in the service of decision-making
• Needs a decision-centred rather than a problem-oriented framing, with appropriate engagement with stakeholders
2. Impacts and vulnerability modelling can then be focused on particular decisions
• Support the development of adaptation pathways that reduce the risks in decision-making under uncertainty
Conclusions
decision-making under uncertainty
3. Initial studies for some sectors show significant net present benefits of acting early with respect to some risks
• Integrated/emergent risk issues (costs and benefits) may be a key driver for government action
• A useful focus for modelling as governments work out whether they should be acting
Systematising a decision-centred approach…
Not all decisions are equal
• Decision lifetimes really matter, for how decisions intersect with climate change
Not all threats are equal, nor equally uncertain
• Some aspects of climate change are far more certain than others
There are many approaches to managing risk
• Use what’s appropriate to the form of climate and other uncertainty• Use what’s appropriate to the form of climate and other uncertainty
Adaptation will not be a once-off action
• Adaptation pathways, with review points, related to climate and other updates
Don’t just assess impacts and vulnerability more precisely!!
