This document summarizes a session from the Second UN-SPIDER Workshop on advancing knowledge for human security and development. The session focused on vulnerability and risk assessment and how remote sensing data can be used for these purposes. The goals of the session were to discuss how remote sensing data can be used for vulnerability and risk assessment at different scales, how it can be combined with statistical data, and who might benefit from using the data. Participants then broke into subgroups to further discuss issues relating to vulnerability, hazards and risk, and using information for disaster preparedness and response.

 B) Hazard and Risk / Dr. Peter Zeil
Institute for Environment & Human Security
 C) Information for disaster preparedness and
response / Dr. Juan C. Villagran
United Nations University
UN-SPIDER Workshop

18. Goals 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?
Institute for Environment & Human Security
 Development of ideas on the web-based platfrom – what
to share…

19. Question for each Sub-Group
 How is the vulnerability and risk assessment structured?
 Which elements at risk can be assessed with remote
sensing (RS) information?
Institute for Environment & Human Security
 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?
