Of the many environmental challenges facing the Baltic Sea, the most serious and difficult to tackle with conventional approaches is the continuing eutrophication, which is caused by excessive nutrient inputs. Nitrogen and phosphorous loads to the Baltic Sea have increased several folds over the last century, reaching the Sea through agricultural run-off and leaching inadequately treated sewage and through airborne emissions from traffic and combustion processes.
The effects of eutrophication are particularly acute in the southern and eastern parts of the Baltic Sea. The impacts of eutrophication include oxygen depletion, reduced water clarity, an increase in filamentous algae, summer blooms of cyanobacteria (blue green algae) and negative effects on the benthic community.
The latest decades’ large-scale investments in waste-water treatment plants and key decisions on cleaner shipping have had an important impact on decreasing the nutrient load. However, to save the sea, further and continued action is needed,41 especially in the agricultural sector, on which progress in nutrient loads reduction greatly depends now. Full implementation of the relevant EU legislation is necessary in restoring the ecosystem status of the sea. This legislation includes the Water Framework Directive,42 Nitrates Directive,43 Urban Waste Water Directive,44 Industrial Emissions Directive45, as well as the Marine Strategy Framework Directive.46 In addition, reinforcement of some measures adopted under these Directives has become apparent and must take place without further delay. In particular it is worth noting that the Nitrates Directive is insufficiently implemented both as regards Nitrates Vulnerable Zone designation and Action Programmes. Also, the measures agreed upon in the Baltic Sea Action Plan (BSAP) of the Helsinki Commission (HELCOM), going beyond the requirements of EU legislation, must be implemented, which is currently at varying stages in the different countries concerned.
Cooperation should be promoted with a broad range of stakeholders, including other priority areas and actors in non-EU Member States in the region, in order to take advantage of the cross-cutting nature of the EUSBSR, to reach the objectives of the MSFD and other relevant legislation and to ensure stakeholders’ commitment to the reduction of nutrient emissions into the sea. As agriculture is the most important source of diffuse nutrient loads into the Baltic Sea, priority area ‘Agri’ is a particularly important stakeholder for priority area ‘Nutri’. Cooperation between the two priority areas is facilitated inter alia under the Agriculture and Environment Forum of HELCOM.
The main problems can be summarised as follows:

  • Continued and increasing nutrient loads into the Baltic Sea:

  • insufficient recycling of nutrients;

  • insufficient nutrient removal in urban waste water treatment plants;

  • structural changes in agricultural production, including centralisation of domestic animal farms and oversupply of manure in some areas;

  • difficulties in achieving rapid results due to for instance the complex cycle of nutrients, especially phosphorus, the long time lag between implementing the measure and observing an effect in the water, and the slow turnover of the water in the sea;

  • increases in run-off and thus eutrophication and other impacts due to climate change.

  • Challenges in cooperation across the macro-region:

  • varying levels of commitment to implement the BSAP;

  • lack of clear support at the highest political level;

  • conflicting policy targets of environmental and agricultural policies;

  • differing views on country-wide nutrient reduction requirements;

  • low awareness of costs-efficiency of nutrient load-reducing measures;

  • low awareness of costs and benefits of reaching the objectives of BSAP;

  • difficulties in monitoring nutrient loads from diffuse sources;

  • difficulties with providing HELCOM with accurate data due to lack of institutional capacity in some countries;

  • challenges in coordinating efforts with third countries.


Targets and indicators

A comprehensive system for the design, the monitoring and the follow-up of indicators and targets will be set up in 2013, under the responsibility of the priority area coordinators. The still missing targets and deadline, baseline, and statistics/information sources related to the below indicators will be defined.
