OSPAR and eutrophication
|
The OSPAR Eutrophication Strategy aims to combat eutrophication in the OSPAR maritime area in order to achieve and maintain a healthy marine environment where anthropogenic eutrophication does not occur. The Eutrophication Committee (EUC) (part of the Hazardous Substances and Eutrophication Committee (HASEC)) facilitates the implementation of the Eutrophication Thematic Strategies by evaluation of the extent of eutrophication problems in the OSPAR maritime area and identifying the actions needed to achieve non-problem areas.
The Common Procedure
To assist Contracting Parties towards the objectives of the Eutrophication Strategy OSPAR developed a common assessment framework: the Common Procedure for the Identification of the Eutrophication Status of the OSPAR Maritime Area. It characterises maritime areas with regard to eutrophication as:
- Non problem areas: there are no grounds for concern that anthropogenic enrichment by nutrients has disturbed or may in the future disturb the marine ecosystem.
- Potential problem areas: there are no reasonable grounds for concern that the anthropogenic contribution of nutrients may be causing or may lead in time to an undesirable disturbance to the marine ecosystem due to elevated levels, trends and/or fluxes in such nutrients.
- Problem areas: there is evidence of an undesirable disturbance to the marine ecosystem due to anthropogenic enrichment by nutrients.
The Common Procedure comprises two phases: the Screening Procedure and the Comprehensive Procedure. In the Screening Procedure Contracting Parties screen their maritime waters in order to identify the areas characterised as non-problem areas. They give information on demographics, optical observations, nutrients, hydrodynamics, agriculture and industry. The Comprehensive Procedure is applied to those areas not identified as non-problem areas in the Screening Procedure and consists of a set of qualitative assessment citeria.
