Environmental and socioeconomic vulnerability analysis BE-AWARE II Final Project ConferenceRonneby, Sweden: 18-19 November 2015 Documentation: Technical sub report 2: Environmental and socioeconomic vulnerability mapping
Objective: • Describe vulnerability on a regional scale. • map features in a consistent, comparable way to compare across country borders. • Add up effects of different relevant environmental and socio-economic features
Large area • Challenge for homogenous mapping • Dependent on available data • Different levels of: • details • coverage • features
3 STEPS: • Identification of sensitive features • Vulnerability ranking of each feature • Total vulnerability mapping
3 STEPS: • Identification of sensitive features
Step 1: ID of features • Identified in BE AWARE I • Final list revised during BE AWARE II • Determined from data availability • Data collected from: • Central sources such as EU institutions, NGO's and international conventions and organisations • Contracting parties • Organised by • Data request note:
Step 1: ID of features 34 Ecological features: 26 Habitats 18 coastal 8 open sea 4 Species 1 fish area 3 bird areas 4 Protected areas
STEP 1– Sensitive socioeconomic features 14 Socioeconomic features: 1 Fisheries offshore & coastal fisheries 3 Aquaculture fish farms Shellfish cultures Algae cultures 5 Tourism & recreation 5 Other
A combination of : • EUNIS habitat classif. system • EU Habitats Directive Ann. 1 Habitat classes EUNIS classification
Examples of mapping • Scaling issues: • Regional maps hide local details • present in data sets and used in analysis • Great variability • Some features left out but still in • marine mammals (MPAs)
Sensitivity HabitatsShoreline classes- UW sandbanks< 20 m> 20 m
Sensitivity HabitatsShoreline classes- Shingle beaches
Bird species in original Data request:- Wintering areas- Breeding areas- Staging areas

3 STEPS: 2. Vulnerability ranking of each feature
Proposed ranking of all features by COWI based on litterature review Ranking workshop determined a final score list: 4 seasons +/- dispersants
Ranking Criteria based on BE AWARE I Fate of oil related to feature Additional criteria for Soc.Econ Potential impact of oil: Sensitivity Recovery Length of interruption Compensation
3 STEPS: 3. Total vulnerability mapping
Vulnerability maps Summing individual vulnerability scores x 4 seasons x dispersed oil spills x non-dispersed spills habitats Re-classifying total vulnerability scores: Very high High Medium low Very low species protected areas soc. economic features Weighting btw. features: 25 % Total: 8 Vulnerability maps 4 seasons x 2 oil spill types
Next step (next talk) Impact x Vulnerability => Damage Base case: Surface Damage Base case: Water column
