The Weekend Read: How the EU Manages Its Vast Seas - Science, Solutions, and the Strategy to Restore a Resilient Ocean.

Welcome to the Weekend Read. Europe’s seas, covering more than 11 million km², are critical ecosystems that feed us, regulate our climate, and provide the majority of species found in Europe with habitats. However, these seas face rapid change due to human activities, including pollution, plastic waste, habitat loss, acidification, and warmer waters from climate change, all of which reduce marine biodiversity and ecosystem resilience. To counter these threats, EU-funded research, primarily under Horizon 2020 and Horizon Europe, is focused on reducing and preventing drivers of marine biodiversity loss and offering solutions for a healthier future. This strategic response is guided by ambitious policies such as the EU Biodiversity Strategy and the Nature Restoration Law, adopted in June 2024, which aim to effectively protect 30% of the EU’s seas by 2030 and restore habitats that are not in good condition. The ultimate goal is to restore biodiversity for the benefit of people, climate, and the planet.Achieving this resilient ocean future relies on cutting-edge science and innovative solutions. EU-funded projects are enhancing ocean governance by improving observation and forecasting systems, providing critical data for fisheries, tourism, and aquaculture. Technological innovations are tackling pollution at the source, such as the AMBI-ROBIC project developing a disruptive, net-zero carbon, and energy-efficient wastewater treatment using anaerobic digestion. Plastic waste is addressed via the ECOLACTIPACK project, which created CareTips®, a fully biodegradable, water-soluble natural polymer derived from dairy protein for plastic-free packaging, and via cleanup technologies like autonomous robots (SeaClear) that detect and collect litter from the seafloor, and bubble barriers (MAELSTROM) that prevent plastics from entering the sea via rivers. Additionally, Nature-Based Solutions (NBS) are being implemented through projects like FutureMARES and MaCoBioS to curb the effects of the climate emergency by restoring critical species like kelp and eelgrass, reviving native flat oysters for coastal sustainability, and constructing artificial dunes to mitigate coastal erosion. This holistic approach also involves integrating activities like sustainable aquaculture and tourism with offshore energy production through multi-use platforms, ensuring economic interests are balanced with environmental protection.Source: Publications Office of the European Union, European Commission: European Research Executive Agency, CORDIS and Directorate-General for Research and Innovation, CORDIS results pack on marine biodiversity, Publications Office of the European Union, 2024, https://data.europa.eu/doi/10.2830/9980277
