Second UN-SPIDER Workshop 13-15 October 2008

Session II: Vulnerability and Risk

Assessment - Introduction -

Dr.-Ing. Jörn Birkmann & Dr. Juan Carlos Villagran de Leon

ityGoals of the Session II

How to use remote sensing data for vulnerability and risk assessment?

How to combine remote sensing data and statistical data regarding vulnerability and risk?

How to use remote sensing data for vulnerability and risk assessment at different scales?

Who can benefit and use the data?

How to ensure the validity and reliability?

ityDimensions of Vulnerability

Social DimensionVulnerability of different social groups,Role of social networks (coping)

Economic DimensionVulnerability of different economic sectors, such as fishery and hotel business in Sri Lanka

Environmental DimensionEnvironmental fragility (groundwater, land)Dependency on environmental services

Institutional DimensionEffectiveness and failure of structures and institutions

SUB-GROUPS

ity3 Sub-Groups

A) Vulnerability / Dr. Jörn Birkmann

B) Hazard and Risk / Dr. Peter Zeil

C) Information for disaster preparedness and response / Dr. Juan C. Villagran

ityGoals of the Sub-Groups

Improved understanding on how remote sensing data is used in vulnerability and risk assessment

Systematization of lessons learnt: what has worked, what not?

Development of ideas on the web-based platfrom – what to share…

ityQuestion for each Sub-Group

How is the vulnerability and risk assessment structured?

Which elements at risk can be assessed with remote sensing (RS) information?

Hot to assess exposure, fragility and response capacities with RS and statistical data

How to integrate remote sensing information and census data within one assessment?

How should the information platform incorporate information regarding vulnerability and risk?

ityThe End

Thank you for your attention!
