Description
Successful proposals will contribute to the impacts of this destination by improving knowledge and developing modelling tools to guide the restoration of degraded ecosystems ensuring the provision of ecosystem services. It will thus contribute to the objectives of the European Climate Law (which requires Member States to promote nature-based solutions and ecosystem-based adaptation) and will improve knowledge to ensure that biodiversity and climate policies and their implementation are coherent, mutually supportive and provide co-benefits for sectoral policies.
Project results are expected to contribute to all the following expected outcomes:
- national competent authorities, decision makers and practitioners having to implement restoration activities benefit from updated knowledge and new tools based on modelling approaches;
- nature restoration is fully taken into account in the modelling frameworks used for climate and land use policies.
The EU biodiversity strategy for 2030 set the following targets for 2030: significant areas of degraded and carbon-rich ecosystems are restored; habitats and species show no deterioration in conservation trend and status, and at least 30% reach favourable conservation status or at least show a positive trend. The EU Nature Restoration Regulation establishes framework within which Member States shall put in place effective and area-based restoration measures with the aim to jointly cover, as a Union target, at least 20 % of land areas and at least 20 % of sea areas by 2030, and all ecosystems in need of restoration by 2050.
The use of models is expected to support national and EU competent authorities and stakeholders for the implementation of the EU Nature Restoration Regulation, in particular in the following areas:
- determination of the good conditions of habitats as defined in the Habitats directive and the good environmental status defined in the Marine strategic framework directive;
- establishment of threshold values for the favourable reference area for habitats and ecosystems covered by the EU Nature Restoration Regulation;
- estimate of ecological needs of species in terms of quantity and quality of their habitats and better understanding of links between habitats and ecosystems restoration and species conservation;
- better understanding of connectivity, functionality, ecological coherence of Natura 2000 network and marine reserve network and competing needs of species;
- analysis of restoration pathways proposed by competent authorities to achieve the short term (2030) and long term (2040-2050) targets of the EU biodiversity strategy for 2030 and the EU Nature Restoration Regulation for all ecosystem types.
Proposals should either address Area A: main focus on terrestrial ecosystems, or Area B: main focus on marine ecosystems. The area (A or B) should be clearly indicated on the application.
For both areas, R&I activities should:
- develop a model as described above capable of simulating dynamic ecosystems processes, including interactions at different scale levels, based on literature review, available datasets or data-basis, realised restoration activities, on-going projects including demonstration cases, and existing guidance. The model should be able to estimate ecological reference values tailored to the specificity of ecosystems in different territories and in given contexts including under climate change, to assess proposed restoration pathways and to contribute to improve/expand other models;
- prioritise ecosystems corresponding to synergies identified between ecosystem restoration and one or several of the following areas: climate change mitigation, climate change adaptation, land degradation neutrality and disaster risk prevention;
- address data gaps with direct observation if needed;
- formulate practical guidelines or advice for practitioners about how to carry out restoration, including when dealing with invasive alien species;
- aim at improving and expanding models used for climate and land-use policies, by coupling modelling functionalities as described above.
Proposals should build on the results of relevant existing projects and envisage enough resources to collaborate with other selected projects under this topic to provide an effective integration of the generated models.
Proposals should build on the knowledge compiled in the assessment reports produced by the Intergovernmental science-policy Platform on Biodiversity and Ecosystem Services (IPBES), including the IPBES scenarios and models assessment, and should show how the planned activities could provide timely information for consideration to future reports.
Concrete efforts should be made to ensure that the data produced in the context of the funded projects is FAIR (Findable, Accessible, Interoperable and Re-usable), particularly in the context of real-time data feeds, exploring workflows that can provide “FAIR-by-design” data, i.e., data that is FAIR from its generation. Possibilities offered by the European Open Science Cloud (EOSC) to store and give access to research data should be considered, including data from in-situ sensors and satellite-based Earth observations.
Citizen Science approach could be appropriate for this action to produce, collect and analyse data.
When dealing with models, actions should promote the highest standards of transparency and openness, as much as possible going well beyond documentation and extending to aspects such as assumptions, protocols, code and data that is managed in compliance with the previously mentioned FAIR principles.
This topic is part of a coordination initiative between ESA and the EC on Earth System Science (ESSI). Projects will be asked to cooperate with projects that will be selected under ESA's Future EO programme as well as under the following topics under this call: HORIZON-CL6-2025-01-BIODIV-04: Large-scale in situ biodiversity observations for better understanding of biodiversity state, drivers of its decline and impacts of policies and HORIZON-CL6-2025-01-BIODIV-06: Assessing and modelling socio-economic impacts of nature restoration. To this end, proposals should plan to allocate sufficient resources for effective coordination, with concrete cooperation activities to be defined at a later stage. Applicants are not expected to contact the ESA or ESA projects to prepare proposals.
Proposals should foresee cooperation with the EC Knowledge Centre for Biodiversity and the Science Service project BioAgora.
Destination & Scope
Under destination “Biodiversity and ecosystem services”, R&I in 2025 provides scientific support to the development and implementation of EU environmental legislation and of European Green Deal initiatives, in line with the new Commission priority “Sustaining our quality of life: food security, water and nature”.
This destination is based on the vision developed in the EU biodiversity strategy for 2030 and supports its implementation, pursuing the orientations of the Work Programmes 2021-2022 and 2023-2024, and notably focuses on the EU Nature Restoration Regulation and other new European Green Deal initiatives such as the proposal for an EU soil monitoring and resilience law, the proposal for an EU forest monitoring law and the EU Taxonomy for Sustainable Activities (specifically the Environmental Delegated Act) and the EU action plan: protecting and restoring marine ecosystems for sustainable and resilient fisheries. R&I activities continue to support the environmental objectives of the common agricultural policy and reflect the strong interconnections between the EU biodiversity strategy for 2030 and the European Green Deal objectives for a competitive, resilient and sustainable agri-food system, including the pollinators initiative.
R&I on biodiversity and ecosystems services, if translated into action, contribute to a clean environment for the EU and Associated Countries, including water, soil, air, health, climate adaptation and risk (including disaster risk) reduction, sustainable bioeconomy and blue economy policies.
This destination also contributes to the twin green and digital transition. Where relevant, advantage should be taken of the use of advanced digital technologies and tools such high-performance computing, Artificial Intelligence (AI) and Environmental Observation where appropriate.
This destination supports the EU leadership in the relevant international fora and develops analysis and tools to reach our international biodiversity commitments, such as those taken in the Kunming-Montreal Global Biodiversity Framework (GBF), in line with the new Commission priorities. It will in particular support the monitoring framework of the GBF. Its activities serve the objectives of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), the Intergovernmental Panel on Climate Change (IPCC) and of the potential International/Intergovernmental Panel for Ocean Sustainability (IPOS).
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” of the Strategic Plan 2025-2027, and more specifically to one or more of the following impacts:
- improved knowledge, innovations, methods, pathways and tools are available to protect healthy ecosystems and to restore degraded ones ensuring the provision of ecosystem services, including for adaptation and/or mitigation to climate change;
- the ongoing biodiversity crisis and its consequences, the benefits of ecosystem services and the need to protect and restore them are better understood. Policymakers and all relevant sectors of society are aware and well informed thereof, and fully grasp opportunities of biodiversity protection and restoration. Society is on a path of transformative change;
- farmers, foresters, and land managers test and implement biodiversity-friendly practices while safeguarding food security and the long-term sustainability of farming and forestry;
- progress towards reaching the goals and targets of the Kunming-Montréal Global Biodiversity Framework contributes to reducing the pressure on biodiversity and to ensuring sustainable development worldwide.
R&I under Destination “Biodiversity and ecosystem services” will mostly deliver under Key Strategic Orientation (KSO) 1 of Horizon Europe Strategic Plan 2025-2027: Green transition and to a lesser extent KSO 3: A more resilient, competitive, inclusive and democratic Europe.
Spending under this destination counts 100% against the target for biodiversity expenditure under Horizon Europe. In addition, most of the activities, especially in the area of ecosystem restoration, contribute to the target for climate expenditure in line with the European Climate Law, which acknowledges that the restoration of ecosystems can maintain, manage and enhance natural sinks.
The Work Programme 2025 supports additional activities of the European Biodiversity Partnership Biodiversa+, while ensuring complementarity of actions with other instruments.
Synergies are sought with:
- EU missions, in particular “A Soil Deal for Europe” and “Restoring our ocean and waters by 2030” in topics dealing with nature restoration;
- Horizon Europe partnerships: in addition to Biodiversa +, several co-funded partnerships under Cluster 6 notably Water4All, sustainable blue economy and agroecology;
- JRC activities, notably the EC Knowledge Centre for Biodiversity (KCBD) and its Science Service for Biodiversity (SSBD), the Competence Centre on Participatory and Deliberative Democracy, the European Technical Support Centre for the Global Biodiversity Framework as requested by the Convention on Biological Diversity, European regional centre for biodiversity and the Global Knowledge Support Service for Biodiversity (GKSSB).
To maximise the impacts of R&I under this destination, international cooperation is encouraged in topics as appropriate. International cooperation is sought, in particular in topics that support IPBES, the implementation of the Kunming-Montreal Global Biodiversity Framework, the Sustainable Development Goals, the Paris Agreement and related international agreements such as the Agreement on the conservation and sustainable use of marine biological diversity of areas beyond national jurisdiction (BBNJ).
Under this destination there is a substantial need for more fundamental research and therefore there is a majority of Research and Innovation Actions (RIAs).
This destination benefits from interdisciplinarity and trans-disciplinarity, including the contribution of social sciences and humanities (SSH), and takes into due account gender and other social categories and their intersections to ensure promotion of democracy and a socially just transition where relevant. Citizens and stakeholders’ engagement will be sought including with living labs. The destination is expected to contribute to the new Commission priority “Protecting our democracy, upholding our values” by engaging with civil society. Furthermore, it strives to take full advantage of the potential of nature restoration and nature-based solutions, to deliver multiple social, economic and environmental co-benefits.
