VULNERABILITY ASSESSMENT (VA)
What is vulnerability?
• The degree of fragility of a person, a group, a community or an area towards defined hazards
• Set of conditions and processes resulting from physical, social, economical and environmental factors, which increase the susceptibility of a community to the impact of hazards
• Vulnerability is determined by the potential of a community to react and withstand a disaster, e.g. its emergency facilities and disaster organisation structure (coping capacity)(Schmidt-Thomé and Jarva, 2003)

Impact matrix as a part of the VA
• Identifying the hotspots of the study area e.g. a beach, houses, oil refinery, underground infrastructure, water supply etc.

Coping Capacity As Part of the VA
• Coping capacity refers to the capacity of an stakeholder, organisation or region, to withstand and cope with the effects of the future sea level rise such as inundation and flooding.- Helps the studied area to understand where its current strengths and weaknesses are.
• Identifying relevant key stakeholders for highest impact hotspots.
- e.g. planners, decision makers, rescue department, local waterworks, environmental experts, private households, oil refinery etc.

Coping Capacity of the Institutions
• Co-operation • Strength of institutions • Trust in decision makers • Guidance of planning • Public awareness
VA is a tool to support local and regional decision makers in analysing and interpreting the impacts of sea level rise on a study areas

Experiences From ITÄ-UUSIMAA Study Area
• Hotspots in Porvoo Housing by the riverbank Contaminated industrial shores The ground water area in Sannainen
• Hotspots in Loviisa Housing by the Rantatie road The railway in use of the Valko harbour The park at the farest end of the Loviisa bay

Interviewees in Itä-Uusimaa Region
• City planners and regional planners • Rescue department • Local water works • Local environmental experts and the Uusimaa
regional environmental centre • Road- and traffic department • Private persons with property in the risk zone,
also city councillors

Interesting Results From Itä-Uusimaa Study Area
• Shores are wanted places for houses and summer cottages in Finland in general
• Hazards related to the oil refinery in Porvoo and the nuclear power plant in Loviisa raise more concern in Itä-Uusimaa
• The long time scale (100 years) makes sea level rise still an abstract hazard
• Guidance of planning quite strong and sea level is taken into account in planning

Planning capacity assessment (examples)
• What is the level of (local official) knowledge about the type, location, and potential of hazards (sea-level rise & flooding)?
• Does development already exist to reduce the potential (land use planning and mitigation)?
• How high is community awareness of the hazard? Difficulty of avoidance of hazard-prone land use
• Are plans and resources available for mitigation? What is the planners interest?
• What kind of social, economical and political resistance is there towards influence on land use?
