BROWN = least suitable

Impacts:

SimCLIMs can be used to:SimCLIMs can be used to:

• Describe baseline climatesDescribe baseline climates• Examine current climate variability and extremesExamine current climate variability and extremes• Assess risks – present and futureAssess risks – present and future• Investigate adaptation – present and futureInvestigate adaptation – present and future• Create climate change scenariosCreate climate change scenarios• Conduct sensitivity analysesConduct sensitivity analyses• Project sectoral impacts of climate and sea level changeProject sectoral impacts of climate and sea level change• Examine risks and uncertaintiesExamine risks and uncertainties• Facilitate integrated impact analysesFacilitate integrated impact analyses

A customised, prototype SimCLIM model can be developed for AIACC projects

Data Required:

• Spatially interpolated monthly climatologies

• Time-series climate data for stations (monthly or daily)

• Downscaled, standardised patterns of monthly temperature and precipitation changes from GCMs.

• Digital elevation model (optional)

Part 3:

The “hands-on” training exercise

Objective

To gain practical experience in:

• selected elements of integrated assessment

• using an Integrated Assessment Model

- Hands-on Training Exercise -

The “Republic of Vanda Islands”The “Republic of Vanda Islands”(an imaginary country)(an imaginary country)

- Hands-on Training Exercise -

Using:

The Island VersionDeveloped by the International Global Change Institute, University of Waikato, New Zealand

- Hands-on Training Exercise -

Problem Focus: Risk Reduction

• Assess current climatic risks• Assess adequacy of current adaptation to climatic

variability and extremes• Develop scenarios of future climate changes• Assess possible future changes in risk• Assess adaptation options for reducing future

risks• Estimate incremental cost ratios

- Hands-on Training Exercise -

Choice of 4 Training Groups• Coastal Flood Risk (storm surges)

• Agricultural Drought Risk

• Risks of Groundwater shortage

• Drought risk to water supply

Aosis

- Hands-on Training Exercise -

Sessions

• All four training groups in each session

• No more than four persons per group

• Each session repeated four times

- Hands-on Training Exercise -
