Identify economic activities relevant to the Policy Issue.

Subtask Description:
Identify economic activities relevant to the Policy Issue.

Action points:

Oder/Odra Estuary, Baltic Sea, Germany (& Poland)

Policy Issue:
Water quality and eutrophication.

Human Activities:
Tourism, agriculture, industrial and urban activities, fishing, shipping.

General Information:
The river loads are responsible for the poor water quality in the lagoon and its highly eutrophic state. Temporary anoxia, fish mortality, algae bloom and poor water transparency reflect the poor water quality state. There is a lot of existing information and previous management efforts for the area. At the moment, the German-Polish cross border integration and cooperation receives much more attention than a river basin-coast cooperation and management. The choice of the PI does not reflect the priority setting in the region itself, but political reasons that did not allow tackling of other issues.

Example of Implementation:
Main economic activities:
Industry: large and small scale – small mainly connected with minor activities in the urban areas.

Agriculture: although the land used covers approximately 70% the upper river basin and 58 % of the middle basin, the contribution of the activity to the area’s gross product is only 3.9 %.

Other economic activities: mainly in the urban areas.

Impacts within the ecosystem:
High nutrient loads in the river, responsible for poor water quality and highly eutrophic state in the lagoon.

Occurrence of temporary anoxia events, fish kills, algae blooms and poor water transparency all reflecting the poor water quality state in the Coastal Zone system.

Ecosystem Services provided by the Oder Estuary region:

Impacts from the Policy Issue

Economic Valuation Techniques

Use value:

Direct Use Value:

Recreation and tourism:

Eutrophication and its effect on smell, algal blooms (algal mats, foam and toxicity) etc. can affect swimming, sports fishing, boating, diving, sailing and other water sports

Market analysis

Planning costs

Agricultural economic models and calculations

Opportunity costs

Travel costs analysis

Hedonic pricing


Contingent Valuation Method


Pollution can affect the perceived beauty of the area

Commercial fisheries:

Eutrophication has resulted in the reduction and elimination of spawning grounds of commercially valuable fish and mussels (cod, herring, sprat, plaice, Maraena whitefish, etc.)

Emission sink:

Nutrient sink from agricultural uses and emission sink for urban and industrial waste water.

Indirect Use Value:

Water quality maintenance:

The coastal ecosystem filters and removes nutrients (nitrate, phosphate) and pesticides that can contaminate water, as well as toxins and other pollutants

Expenditures for preventive measures

Estimation of changes in productivity


Restoration costs


Support of food webs and nutrient cycling.

Option value:


Preserving biological diversity and genetic materials for future uses.

Main economic indicators:
