BE-AWARE II Final Project ConferenceRonneby, Sweden: 18-19 November 2015

• Environmental and socioeconomic vulnerability analysis

Documentation: Technical sub report 2: Environmental and socioeconomic vulnerability mapping

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

Vulnerability mapping 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:

Vulnerability mappingSensitive Ecological features in the BA area

Shoreline and Coastal Habitats Open Sea Habitats Exposed rocky shores and reefs on less

than 20m depth; Exposed rocky shores and reefs on

more than 20m depth: Sheltered rocky shores and reefs on

less than 20m depth: Sheltered rocky shores and reefs on

more than 20m depth; Littoral chalk communities; Sandy beaches; Shingle beaches; Tidal sand and mud flats; Salt marshes; Underwater sandbanks on less than

20m depth Underwater sandbanks on more than

20m depth; Biogenic reefs on less than 20m depth Biogenic reefs on more than 20m

depth Maerl beds Seagrass beds (Zostera sp. > 5%) Estuaries Coastal lagoons (open to the sea); Large shallow inlets and bays;

Open water column on less than 20 m depth

Deep sea water column (>20 m depth) Deep sea floor (>20m depth) Seamounts Coral gardens and sponge aggregations Carbonate mounds Lophelia pertusa reefs Sea-pen and burrowing megafauna

Habitat classesA combination of :•EUNIS habitat classif. system•EU Habitats Directive Ann. 1

EUNIS classification


Habitat classes – Harmonisation


• 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)
