Presentation Transcript

  1. GES : scales for assessment and aggregation methods MSCG 12-13 November 2013, Brussels European Commission DG Environment Unit C.2 Marine Environment and Water Industry

  2. Status • Limited guidance in Common Understanding document • Highly varied approaches by MS in 2012 reporting • Project to review approaches and develop guidance (spring 2013-spring 2014) • Draft report on analysis • Workshop with MS 23 October • Work guided by GES Drafting Group • Next steps: • Finalise analytical report • Develop guidance with MS • Need for further work after project?

  3. Preliminary conclusions/principles (1) • Determination of GES: some aspects at EU level (e.g. hazardous substances), some at regional level (ecosystem-specific) • Ecosystem-based subdivision of regions/sub-regions – supplemented with WFD and national boundaries for some descriptors (e.g. HELCOM approach) • Nested scales – allow aggregation from smaller to larger areas) • Link state and pressure scales (but pressure scales typically can be smaller)

  4. Preliminary conclusions/principles (2) • Balance between too many and too few areas – can a nested system fit most/all purposes? • Accommodate administrative and management needed as well as ecosystem-based assessments • Aggregation – important not to mask problem areas (e.g. use proportion of area at GES) • Integration of indicators/criteria – need both pressure and impact assessment
