Modifications
• Contextualise (Norway)
• Add time (the future/climate change)

Social vulnerabilityProduct of Social inequalities and Place
inequalities • Social Vulnerability Index (SoVI)
Cutter S L, Boroff, B J, Shirley W L, 2003, Social Vulnerability to Environmental Hazards, Social Science Quarterly, 84 (2): 242 – 261.
• Social Vulnerability Index (SoVI) for the United States based on 1990 data• County level 3,141 units• Collected several variables which could act as indicators on social
vulnerability• Factor analysis (PCA): 42 variables 11 independent factors• Additive model summary score (SoVI)• Mapping SoVI identify most vulnerable counties

How to deal with the future?
• Climate is obviously not the only thing that is changing...
• Is it possible to say something meaningful about socio-economic changes in a 50-80 year perspective? How?
• Local socio-economic scenarios?

Using existing scenarios: Some issues to be addressed
Not dealing directly with climate change issues nor hazards- how to make more relevant?
Cover a period up to 2020- we need scenarios up to 2050 or longer
How to make a spatial interpretation, how to map the scenarios?
How to identify quantifiable/measurable indicators?

Forever green Renewed interest in small scale agriculture and local fishing Growth of small scale rural enterprises- decline in traditional large scale industries Decentralised and scattered settlements both in coastal areas and inland Decentralised political decision-making, emphasis on active participation (Limited population growth) Little immigration More expensive transport -emphasis on public solutions Forever Young Growth in service industries/public welfare production Growth of smaller urban settlements, decentralised urbanisation? Big public sector Growth in population Young population but also active aged Substantial organised (unskilled) immigration Development of good infrastructure/roads and mixed transport solutions Forever Growth Growth in knowledge based /high tech industries – more efficient and large scale agriculture Substantial Urban growth mainly around Trondheim and along Trondheimsfjorden (Orkanger to Steinkjer) Well modern but vulnerable infrastructure (roads, railroads) Growth in private/market based solutions Substantial population growth Immigration of well-educated people
