Climate Adaptation Flagship Goal To equip policy makers, industries and communities with practical and effective adaptation options to climate change and variability and, climate change and variability and, in doing so, create in the national interest $3 billion per annum in net benefits by 2030.

Australia: vulnerable among OECD nations < °C global warming > (a) Qualitatively different levels of impact, vulnerabilities and adaptation needs at 4°C compared to 2°C (b) Proactive adaptation needed (b) Proactive adaptation needed to plan for stabilising at 2°C are very different to those needed for 2°C heading for 4°C+ Could be disempowering… IPCC (2007) (Fig.11.4: Australia)

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!

Adaptation timing and priorities Today’s decisions must account for how long their effects will be felt 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 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 2150 2200 2250 2300
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
Systematising responses 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 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! Stafford Smith et al, PhilTransRoySoc 2010
