Europe’s seas face uncertain future if urgent, coherent action not taken
Faced with the increased threats posed by overexploitation of marine resources, pollution and climate change, urgent action is needed to bring Europe’s seas back to good condition. According to the European Environment Agency’s report on Europe’s marine ecosystems, published today, we are running out of time to reverse decades of neglect and misuse.
The current condition of Europe’s seas is generally poor according to the EEA report ‘Marine Messages II.’. This is bad news for people as it affects our quality of life, livelihoods and economies. The condition of our seas determines their capacity to supply, amongst others, oxygen, food, a habitable climate, and certain raw materials, and it also supports our recreation, leisure and health.
Historic and current use of our seas — from the Baltic to the Mediterranean — is taking its toll, resulting in changes in the composition of marine species and habitats to changes in the seas’ overall physical and chemical make-up. Added to these complex problems is climate change, which is worsening the impacts of the other threats. The combined effects of these changes are currently on a path which could cause irreversible damage to marine ecosystems, the EEA report says. There are, however, signs of marine ecosystem recovery in some areas as a result of significant, often decade-long, efforts to reduce certain impacts like those caused by contaminants, eutrophication and overfishing, the report says.
Status for Norwegian waters
NIVA (The Norwegian Institute for Water Research) Denmark is a major contributor to the report, and many of the tools applied to determine the status of Europe’s water are NIVA-developed.
"In most parts of Norwegian marine waters, the MMII report concludes that ecosystem health is impaired (classified as being problem areas) due to (over-)fishing of specific commercial fish stock. In few areas, the cause of impairment is related to contaminants and inputs of nutrients", says Jesper Harbo Andersen, chief scientist at NIVA Denmark.
Andersen has, together with colleagues from NIVA and NIVA Denmark, been heavily involved in report.
“We are proud to have collaborated closely with the EEA in this marine assessment; although our common findings raises concern about the current condition of Europe’s seas”, says Jesper Harbo Andersen, chief scientist at NIVA Denmark.
An European effort
“Our seas and marine ecosystems are suffering as a result of years of severe over-exploitation and neglect. We may soon reach a point of no return, but, as our report confirms, we still have a chance to restore our marine ecosystems if we act decisively and coherently and strike a sustainable balance between the way we use of seas and our impact on the marine environment. In this context, the new EU Biodiversity Strategy to 2030 and other elements of the European Green Deal bring renewed hope that urgent and coherent action for protection and restoration will be underway,” said Hans Bruyninckx, EEA Executive Director.
EU Member States are unlikely to achieve in all their waters by 2020 the ‘good environmental status’ goal of the EU’s Marine Strategy Framework Directive (MSFD), the main EU law for marine environmental protection. Still, significant progress and achievements have been made since the Directive is in place. These conclusions are echoed by the European Commission’s own report (LINK), reviewing the current state of implementation of this Directive, which is also published today. The EEA’s report feeds into the Commission’s review and suggests solutions that can help the EU achieve the legislation’s goal of clean, healthy and productive seas, mainly through ecosystem-based management.
“’Marine Messages II’ combines scientific excellence, policy and perspectives and sets a new standard for how assessments should be written”, Jesper Andersen says.
All the data reported by EU Member States to the Commission is made public for the first time at a dedicated website on WISE-Marine, as well as data products and visualization tools that provide an overview of the status of the marine environment in the EU.
Other key findings:
- The EU’s maritime economy continues to grow and the competition for marine resources like fish, fossil fuels, minerals or renewable energy production and space is expected to increase. This will add extra pressure on already overexploited marine ecosystems. To avoid this, the growth in this sector needs to be decoupled from the degradation and depletion of marine ecosystem and be contained within the limits for their sustainable use.
- Despite EU and global commitments, biodiversity loss in Europe’s seas has not been halted. A high number of marine species and habitat assessments continue to show an ‘unfavourable conservation status.’ Studies point to the challenging situation species like seabirds, marine mammals (seals and whales), and fish stocks, like cod, find themselves in.
- Management measures targeting individual marine species and habitats have led to improvements in their condition in some EU marine regions, but this fragmented success does not offset the combined effects of multiple pressures from human activities across all of Europe's seas.
- Where regional cooperation has been established and implemented consistently, negative trends in certain pressures are beginning to be reversed, for example, levels of nutrients and contaminants or the introduction of non‐indigenous species.
- Land-sea interactions, as well as the significance of coastal areas, are important dimensions to consider when actions are designed to reduce pressures on the marine environment.
- Changes in ocean temperature and oxygen content, and ocean acidification, indicate that negative systemic changes are taking place in EU marine regions, which further reduce marine ecosystems' resilience including resilience to climate change.
- Past EU and regional policy implementation help identify a set of lessons for restoring marine ecosystems, which should be used when coming up with actions and solutions to achieve clean, healthy and productive seas.
- With political resolve, additional resources and increased coordination among stakeholders and policy integration, Europe can move towards a 'good condition' for its seas within the existing EU policy framework by 2030. To achieve this goal, pressures on marine ecosystems must to be reduced. With its ambition to protect 30% of Europe’s seas and 10% under ‘strict protection’, the new EU Biodiversity Strategy to 2030 (LINK) brings a new impetus for reducing such pressures.
- Achieving good condition for Europe’s seas is instrumental to the Sustainable Blue Economy and maritime spatial planning objectives as reflected in the European Green Deal.
