1. Towards shared water assessments
Shared environmental information system - SEIS
Peter Kristensen
Project Manager
Inland water data & indicators
Welcome participants and highlight the title as the working title for the entire team meeting – not all questions will be answered in this presentation, but hopefully in the course of the day

2. Much valuable water information is available at country level
Water websites describing in water resources, water pollution and state of water systems.
Water chapter in SoE reports
State of water and many detailed reports
During the last years several countries have established Internet based services similar to the WISE-viewer such as database access and Web-GIS functionality that provide the interested public with access to monitoring results.

3. State of the Environment Reporting Information System (SERIS) http://www.eionet.europa.eu/seris
Project 4 (SEIS IP) SERIS upgrade
SERIS - Water

4. SERIS 2.0 – SERIS Water SERIS update
Information in SERIS is not always up-to-date
Restricted to SoE reports including water chapters
SERIS - Water
WISE is already the European water portal (policies – water data – European assessments)
Should country/RBD water assessments be linked to WISE/SEIS?
How could it be done?

5. where to find the right information?
Too much information-

6. National WFD links in WISE
Not water assessments

7. European water assessment should:
provide the basis for identification and assessment of environmental problems and the dominant threats at regional and European levels
provide information necessary to enable actions/policies to be taken to improve the environmental state of the water bodies and to ensure sustainable development

8. Current data flows for European water assessments

9. Current data and information flows and benefits of shared water assessments
The current data and information flows from country to European level are unidirectional.
Current data flows are only covering part of the information needed for European assessments.
They are not taking enough stock of results from assessments and analysis at national and RBD level.
Links from European assessments to national and RBD assessments would enable access to more specific and detailed information.
Links to national results could improve the timeliness and make the assessments more policy relevant
Increased ownership of European assessments

10. From exchange of data to shared water assessments
Current:
Countries report data
EEA producing European assessments
Shared water assessments:
Data available at source
Use of results from national assessments
Cross-referencing between national and European assessments

11. Towards shared water assessments

12. Linking RBD, country and European assessments

13. Nitrate concentration in rivers
Map and diagram illustrating nitrate concentration and trend in Walloon rivers
European (EEA and DG ENV) and country assessments generally have:
• A map illustrating the concentration level
• Trend graphs illustrating the development in nitrate concentration
The following example is a first rough visualisation of shared water assessments

14. Example
In the future water assessments reporting on nitrate concentration can be done as a co-operation between EEA and the countries, where EEA together with the countries produce European assessments and then link to similar assessments produced at country/RBD or watershed level
On the following pages is by a simple template:
key message;
map & trend graph; assessment;
links to other geographical scales and
link to more detailed information
illustrated how European and national assessments of nitrate/nitrogen in rivers can be linked.

16. Challenges
There are several challenges, which require a close cooperation between EEA and member countries in the Eionet.
Many of the challenges have to be explored and discussed with Eionet partners in the coming years.
The most obvious are the following:
• Quality assurance: Consistent quality assurance of the basic data is the first vital step to a good comparability between member countries
• Streamlining/harmonisation: As the examples in the previous section show the approaches for assessments should be comparable (e.g. map and trend graph).
• Commitment by countries to participate in the exercise.
Resource constraints
Volunteer countries together with EEA to develop the methodology

18. Questions for further discussion
Is the vision of shared water assessments well described (paper and presentation)? Where are clarifications needed?
Are the benefits and challenges well described? What should be added?
Is there an interest by member countries in developing this vision further and who would volunteer to co-operate with EEA on the further development?
