Components of the sufficiency of measures (SOM) analysis

Step 4

Features of SOM analysis

• Supports the BSAP update by assessing how far we

are from achieving GES with existing measures

• Provides supporting information to identify need for

potential new measures

• First time SOM assessment is done in this extent
• Same approach applied across all topics to ensure

comparability and coherence (birds, mammals, fish, marine litter, underwater noise, input of nutrients, etc.)

Main components in SOM analysis using expert elicitation

• 1. Linking activities to pressures (step 3)
• 2. Effects of measures on pressures (step 4)
• 3. Linking pressures with state components

(step 6)

• Information from scientific literature and

expert elicitation to allow for comprehensive inclusion of measures, pressures and state components

Components of the sufficiency of measures (SOM) analysis

Step 4

Steps 4 and 6 in the SOM analysis

• Step 4: Estimation of effects of measures

– Estimate of the reduction in a specific pressure (in %) from a generalized measure

• Step 6: Linking pressures with state

components

– Links between pressures and state components – Depending on the existence of GES threshold:

a) Required pressure reduction (in %) to reach or maintain GES b) Change in the state component from a specific reduction in pressures (in %)

Steps 4 and 6 in the SOM analysis

• Expert elicitations (workshops and surveys)
• Literature, studies and models to complement

and use as reference points

• Discussed and supported by the SOM Platform

2-2019 meeting

Current status of work

• Mammals (EG MAMA), birds (JWG BIRD), and

hazardous substances SOM workshops implemented

• Remaining workshops:

– Fish, 4-6 November, Warsaw – Benthic habitats, 14 November, Helsinki

• Online surveys: noise, litter, eutrophication

SOM hazardous substances workshop

• Workshop objectives

– Provide background information on the sufficiency of measures (SOM) analysis in the BSAP update – Describe the expert elicitation approach – Test and discuss the components and structure of the expert surveys – Gather valuable comments and feedback for finalizing the surveys

• Notes from the workshop will be made avaliable

soon

SOM hazardous substances Next steps

• Secretariat will incorporate workshop proposals into

the surveys

• Updated surveys will be ready for distribution in

November

• Workshop concluded that all survey questions will

likely not be possible to answer by one expert

Proposal to distribute to workshop participants, EN Hazardous substances, and CPs would be requested to nominate additional experts to contribute to the survey

Document 8-12

Activity-Pressure data for loss and disturbance to the seabed

• Based on the approach used in HOLAS II

– Links percent contribution of activities to the two physical disturbance pressures

• Document also presented to S&C 11

– Agreed to provide written comments by 6.11 to the Secretariat

Proposal that a single consolidated national response is

• rganized through State & Conservation contacts by the

agreed date

Document 8-13

Activity-Pressure data for marine litter and underwater noise

• Based on expert surveys
• Litter
• Responses from FI, SE, DE, DK
• In communication with PL, LV
• Noise
• Responses from SE, EE, PL, DE
• In communication with DK

Validation process

Working mode alternatives

• 1. Forward expert input to the analysis for validation

as they become ready

• 2. Consolidate all input related to Pressure WG and

make it available at the same time.

Note: consolidated input will be ready in December 2019 at the earliest

Approval process alternatives

• 1. Correspondence
• 2. Online meeting
