2 nd AIACC Asia and the Pacific Regional Workshop A Risk-Based Approach to Adaptation ( ADB Technical Assistance to the Pacific) Presented by: Edy Brotoisworo Asian Development Bank
3
Climate Change Adaptation Program for the Pacific (CLIMAP) IMPLEMENTATION: Asian Development Bank IN COOPERATION WITH:Government of FSM Government of the Cook Islands SOURCE OF FUNDING: Canadian Government under the Canadian Cooperation Fund for Climate Change – GHG abatement, carbon sequestration and adaptation CONSULTANT: Maunsell Ltd, in association with: International Global Change Institute (IGCI)
4
Objectives: mainstreaming climate adaptation through integrated risk reduction (CCIRR) into development planning in selected PDMCs and ADB operations Activities: a. ADB Operations b. Pilot activities (Cook Islands & FSM)
5
CLIMATE SYSTEM Extreme Events Variability Change TIME Human Activities Consequences (Characterize & Evaluate) Likelihood (Characterize & Evaluate) Reduce Risk through Disaster Reduction and Adaptation Raise Risk Threshold through Adaptation Reduce Risk through Greenhouse Gas Mitigation Unacceptable Risks Acceptable Risks Learn from Experience Responding to Climate Variability & Change

How much warmer will it be? Increase in mean temperature by 2100 3oF3oF
8
By how much will sea level rise? 0.5 ft lowest emissions 1.3 ft typical emissions 2.8 ft highest emissions

Adaptation to climate change is, in large part, a continuous process that involves the adjustment of society to changing risks arising from climatic extremes KEY PREMISE

FSM Case Studies
20
Reflecting Climate Risks in Infrastructure Design and Local Level Decision Making Demonstrated by “Climate Proofing” infrastructure and other Development projects Reflecting Climate Risks in Landuse Planning, Regulations and Permitting Demonstrated by “Climate Proofing” such instruments as the Building Code, EIA Regulations and Procedures, And Health Regulations Reflecting Climate Risks in National Development Planning Demonstrated by “Climate Proofing” National Strategic Development Plans Immediate, Project Level Long Term, National Level “Cimate Proofed” Development Enabling Environment CCAIRR Promotes Integration…… …….Mainstreaming “Climate Proofing” is shortand for reducing, to acceptable levels, the risks due to climate variability and change, including extreme events
21
Climate Proofing FSM’s National Strategic Development Plan “……… Infrastructure designed, located, built and maintained to avoid unacceptable risks to infrastructure associated with natural hazards, including weather and climate extremes, variability and change.” “……… Conduct risk assessments at state level and develop national- and state-level guidelines to ensure risks to infrastructure development projects are identified and addressed in a cost effective manner at the design stage.” National Strategic Development Plan

How will Climate Change Reduce Project Sustainability?
23
Roading Project: Kosrae (FSM) Design Life: 50 yr Design Rainfall: Hourly rainfall with return period of 25 yr Used: 177 mm 2000: 190 mm 2050: 254 mm
24
Climate Change will Increase Road Maintenance Costs
25
How can Project Sustainability be Maintained Despite Climate Change? “Climate Proofing” is shortand for reducing, to acceptable levels, the risks due to climate variability and change, including extreme events

Cost-Benefit Analysis: RS4 Section Yet To Be Built Net Present Values: Current Design No climate change$4,475,200 With climate change$7,803,064 Climate Proofed Design With climate change$4,986,364 Internal Rate of Return11%
28
Costs (2004 US$) To be built section (6.6 km) US$ 77,449 per km Built section (3.2 km) US$ 242,558 per km Incremental Cost of Climate Proofing the Road Higher costs if climate proofing is retroactive

36
Some Key Points………. Despite international efforts to reduce greeenhouse gas emissions, the need to adapt to climate change is inevitable Climate change will manifest largely as changes in the frequency and consequences of extreme events, rather than as long-term trends in average conditions Adaptation should be based on effective and efficient risk reduction strategies Adaptation costs (including incremental costs) and benefits can be quantified. Typically adaptation is a cost effective intervention, especially when implemented at the design stage of a project. Retrospective adaptation incurs far greater costs
37
Some Key Points………. Requires integration (“mainstreaming”) of adaptation, across time scales and three levels: –National policy: National Strategic Development Plan –Sector policy: Landuse planning, regulation & enforcement –Project planning and implementation
