Adaptation is the ability of a system
to adjust to climate change (includingclimate variability and extremes) tomoderate potential damages, to takeadvantage of opportunities, or to copewith the consequences.
(Source: IPCC 4th Assessment Report, 2007)
What is adaptation?

water adaptation needs
knowledge and adaptation management
• develop knowledge on impacts and
vulnerabilities
• integrating adaptation into wider policies
• develop specific climate adaptationguidelines and tools for water planners andpractitioners

basin adaptation:Citarum River Basin (Indonesia)
Climate Risk Assessment Process:
1. Identification of climate sensitivity
2. Climate modeling and projection of risks
3. Assessment of climate impact
and adaptation strategies:
i. Creation of hydroclimatologic scenarios
ii. Development of adaptation strategies thatcreate resilience to the expectedhydroclimatologic challenges

water adaptation
• adaptation needs action across disciplines,sectors and organisations
• whilst mitigation is largely “in the air”,adaptation is mainly about “water”
• integrated Water Resources Management(IWRM) is a sensible framework for climatechange adaptation

adaptation investment needs
• more extensive adaptation than is currently occurring is
required to reduce vulnerability to future climate change• poverty is the largest barrier to developing the capacity
to cope
• For a one meter sea level rise, global protection costscould amount to $1 trillion (Asia)

G8 Hokkaido Toyako Summit Leaders
DeclarationHokkaido Toyako, 8 July 2008
Recognizing that poorer countries are among the mostvulnerable to the adverse impacts of climate change, we will
continue and enhance cooperation with developingcountries, in particular least developed countries (LDCs) andsmall island developing states, in their efforts to adapt toclimate change including disaster risk reduction.
To address this issue, we commit to support urgent actionsto mainstream adaptation into broader development
strategies and encourage developing countries themselvesto integrate adaptation into their development policies. Theearly start of activities under the UNFCCC Adaptation Fundshould make an important contribution in this respect. We
call on the multilateral development banks and otherdevelopment agencies to support countries in this endeavor.

in Asia: significant and immediate
investments are needed in resources andinfrastructure.
the costs to Asia, particularly to the poor,will be high. Inaction on adaptation will bevisible, and socially and politically
uncomfortable.
