Description
Expected Outcome:
Project results are expected to contribute to all of the following expected outcomes:
- Member States and Associated Countries contribute to the implementation of area-based management tools, such as protection targets and adaptive management approaches for deep-sea regions under the Treaty on Biodiversity Beyond National Jurisdiction (BBNJ) and the Kunming-Montreal Global Biodiversity Framework (GBF), for Regional fisheries Management Organisations (RFMOs) and for transitions areas with the EU exclusive economic zone notably by identifying Ecologically and biologically significant marine areas (EBSAS), and informing the next Global Assessment of Biodiversity and Ecosystem Services;
- Public Authorities prioritise deep sea areas for inclusion in their 30% protection target while enhancing maritime spatial planning achieved through science-based information, habitat mapping and ecosystem-based approach, aligned with the EU strategies for biodiversity and climate adaptation by 2030.
Scope:
The deep sea represents 90% of the Ocean volume and remains the least explored biome of the planet. Nevertheless, we know that the deep sea forms an extensive and complex ensemble of ecosystems which functioning is crucial to the rest of the biosphere, global biogeochemical cycles and ecosystems upon which much terrestrial life, including human civilisation, depends. The critical limiting factors in the definition and implementation of protection and restoration measures are the lack of biodiversity knowledge and appropriate monitoring, especially in layers below 1000 m. The main reasons are the limited access and high cost of explorations of the diversity of biotopes in the deep sea, and the resources available to identify organisms across the full range of sizes (from microorganisms to megafauna) and describe ecosystems functioning.
In line with the objectives and targets of the EU biodiversity strategy for 2030, the EU Nature Restoration Regulation, the Marine Strategy Framework Directive, the EU climate adaptation strategy, the strategy for European life sciences, the European Ocean Pact, the Treaty on Biodiversity Beyond National Jurisdiction (BBNJ) and the Kunming-Montreal Global Biodiversity Framework (GBF), proposals should:
- fill the gaps in geographical coverage in habitats mapping, species inventory, genetic diversity, ecological functioning, food webs and ecological connectivity (including migratory species) of deep sea ecosystems in the bathypelagic and abyssopelagic zones (abyssal seafloor, hydrothermal sites, seamounts, canyons and across the water column) between them and with shallower ocean zones (mesopelagic, epipelagic, coastal...);
- develop, integrate and deploy imaging, acoustic, multi-omics, genomics and taxonomic technologies and methodologies for the inventory and fast identification of deep-sea marine species from microbes, invertebrates to migratory species, apex predators such as sharks and mammals, corals and other habitat-forming species, generating reference datasets from identified voucher specimens and novel methods to improve biodiversity monitoring and inventory and the discovery of novel biological traits, enhancing understanding of ecosystem resilience to climate and anthropogenic pressures;
- contribute to the Global Taxonomy Initiative of the Convention on Biological Diversity (CBD) and to free and open access to the Global Biodiversity Information Facility’s biodiversity data;
- establish baselines, spatial and temporal dynamics, assess and predict the cumulated impacts from climate change and other anthropogenic stressors including underwater noise, on ecosystems functioning and services, including the biological carbon pump fisheries stock;
- describe holistic interactions between the deep sea, Ocean and planetary health and propose actionable knowledge by involving multiple stakeholders for identifying adaptive management approaches, and mitigation and conservation scenarios for prioritised deep sea areas to reduce impacts of climate change and other anthropogenic stressors on ecosystem structure and functioning;
- identify the indicators and thresholds, such as Essential Ocean Variables (EOV) and Essential Biodiversity Variables (EBV) and propose cost-effective observation approaches and the data integration, for the long-term monitoring and the modelling of deep-sea biodiversity and ecosystems functioning, covering oxygen concentration, carbon fluxes, nutrients and biogeochemistry, to inform management on impacts and conservation or mitigation measures.
Proposals should foresee dedicated tasks and resources for cooperating with projects funded under this topic as well as with other relevant international, Horizon Europe and Horizon 2020 projects on marine biodiversity, functional ecology and on observation, mapping, monitoring and modelling. Proposals should also foresee appropriate resources to ensure close cooperation with the EC Knowledge Centre for Biodiversity (KCBD) and its Science Service. International cooperation is encouraged.
Destination & Scope
This destination will mostly support the EU Commission priority ‘Sustaining our quality of life: food security, water and nature’.
The implementation of the EU Green Deal[1] will continue to guide R&I in this destination. R&I will develop knowledge and tools to support the implementation of the EU biodiversity strategy for 2030[2] and notably the EU Nature Restoration Regulation[3], including with the development of nature credits as proposed in the Nature Credits Roadmap[4]. This destination will also address the EU proposal for a Directive on soil monitoring and resilience[5], the EU proposal for a Regulation on a forest monitoring framework[6] and will inform deliberations on EU biodiversity policy after 2030, thus protecting our natural world. Nature-based Solutions are deep-rooted in this destination, which will support the EU climate adaptation strategy[7] and the EU climate mitigation targets by maintaining or improving natural carbon sinks, since natural ecosystems store large amounts of carbon globally and ecosystems’ carbon sequestration potential is tightly linked to their biological diversity. R&I should particularly assess the ecosystems ongoing ability to sequester carbon and, if necessary, focus more on ecosystems that reliably do so while also providing benefits to biodiversity.
Actions will contribute to the European Ocean Pact[8], to the European Water Resilience Strategy[9] and to the EU legislative proposal on pollutants in EU waters[10] (update of chemical substances listed for control).
R&I activities for sustainable farming, fishing and aquaculture will be supported in alignment with the Vision for Agriculture and Food[11], the Vision for Fisheries and Aquaculture towards 2040[12], as well as with the environmental objectives of the Common Agricultural Policy[13] and the EU Action Plan for the Development of Organic Production[14]. These efforts will enhance biodiversity and climate-resilient farming practices, ensuring the long-term competitiveness of these sectors within ecological boundaries, and foster innovation to drive sustainable food production.
R&I actions under this destination will encourage international cooperation in line with the global approach on R&I, contributing to EU international biodiversity commitments, notably those taken under the Kunming-Montreal Global Biodiversity Framework (GBF)[15], which defines targets for the medium term (2030) and goals for the long term (2050). This destination will also support the Paris Agreement[16], the Sustainable Development Goals[17] and the United Nations agreement on biodiversity beyond national jurisdiction (BBNJ Agreement)[18]. Support to processes of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES)[19] will be continued.
Complementarities and synergies will be ensured with the activities supported by the co-funded partnerships Biodiversa+[20], Water4All[21] and the co-funded partnership on Agroecology[22], and LIFE[23] projects, particularly on nature restoration and protection.
The destination supports unlocking the unique assets for research and innovation of the EU outermost regions, in line with the EU strategy for outermost regions[24].
Expected impact: Proposals for topics under this destination should set out a credible pathway contributing to “putting biodiversity on a path to recovery, and protecting and restoring ecosystems and their services”, and more specifically to one or more of the following expected impacts:
- Knowledge on biodiversity status and trends and drivers of biodiversity loss is improved;
- Innovations, methods, pathways, models and tools are available and used to protect healthy and resilient ecosystems and to restore degraded ones, ensuring the continuous provision of ecosystem services, including for adaptation and/or mitigation to climate change;
- The ongoing biodiversity crisis and its consequences, notably on ecosystem functioning and their services, and the need to monitor, protect, restore and sustainably use biodiversity are better understood to better benefit the whole society in an inclusive way;
- Policymakers and stakeholders, all relevant economic sectors and society are aware and well informed of relevant challenges and opportunities of biodiversity protection, restoration and sustainable use, leading to better implementation of the biodiversity legislation and better valuation of ecosystem services, leading to transformative change towards a nature positive economy;
- Farmers, foresters, land and sea managers, fishers and aquaculture producers have access to key information, and test and implement biodiversity-friendly management practices, while safeguarding food and water security and fostering competitiveness, demonstrating the long-term sustainability of these sectors;
- Progress towards international commitments worldwide on biodiversity is made.
