Map of the Week – Regional Sea Conventions

News article |
The European Union Member States are contracting parties to four Conventions: the Convention for the Protection of the Marine Environment in the North-East Atlantic (OSPAR), the Convention on the Protection of the Marine Environment in the Baltic Sea Area (HELCOM), the Convention for the Protection of Marine Environment and the Coastal Region of the Mediterranean (UNEP-MAP) and the Convention for the Protection of the Black Sea (Black Sea Commission).

Tomorrow, 11 October 2024, the hybrid seminar ‘Sustainable agriculture for a healthy Baltic Sea’, organised by the Helsinki Convention (HELCOM) and the Embassy of Lithuania in Finland, will take place to celebrate the arrival of the “Save the Baltic Sea” expedition, winner of the 2023 EU4Ocean Challenge of the Year, in Helsinki (Finland). This event will explore how governments, scientists, policymakers, the agriculture industry, and citizens can collaborate to reduce pollution in the Baltic Sea, one of the world’s most polluted seas [1]. Presentations and a panel discussion will provide  opportunities to address challenges due to eutrophication by exploring sustainable agricultural practices.

This week’s map highlights the four Regional Sea Conventions working to protect Europe’s marine environments through cooperation between European  Member States (MS) and neighbouring countries. These conventions include the Helsinki Convention (HELCOM)Barcelona Convention (UNEP-MAP)Bucharest Convention (Black Sea Commission), and OSPAR Convention (OSPAR). Aligned with the European Union (EU)’s Marine Strategy Framework Directive (MSFD), these conventions promote sustainable seas and conserving ecosystems. Articles 6 and 8 of the MSFD refer to these conventions to develop strategies and assess marine conditions. Each convention has action plans addressing land- and sea-based pressures, maintaining biodiversity, and applying the ecosystem approach with objectives, targets, and monitoring indicators [2].

A key issue addressed by HELCOM in the Baltic Sea is eutrophication [3]. Over the past 50 years, eutrophication has become a major water quality issue. This process occurs when excess nutrients like nitrogen and phosphorus lead to an overgrowth of phytoplankton(microscopic marine algae). Indeed, plankton populations respond rapidly to changes in their environment, making them effective early warning indicators for detecting shifts in ocean conditions [5]. This leads to harmful algal blooms and oxygen depletion, which damage marine ecosystems and reduce biodiversity [4]. Agriculture, particularly livestock farming, is the main contributor to eutrophication. It is responsible for 94% of reduced nitrogen deposition [5]. Although all sea basins are concerned in Europe, it is a particularly important issue for the Baltic Sea. At least 97% of the Baltic Sea was assessed as eutrophic in 2011-2016 [6]. Therefore, HELCOM parties adopted the Baltic Sea Action Plan (2007, revised 2021) and the Baltic Sea Regional Nutrient Strategy (2021) to call for major reductions in farming nutrient inputs and measures to limit phosphorus and nitrogen losses [7]. Additionally, the EU’s Zero Pollution Plan aims to cut ecosystem areas at risk of eutrophication from nitrogen deposition by 25% by 2030. Finally, key initiatives such as the Farm to Fork Strategy and 2030 Biodiversity Plan also aim to address this issue [5] .
