Description

Expected outcome

This topic aims at directly engaging with and supporting riparian and coastal areas, waterfront cities and islands and their communities in demonstrating and accelerating the transitions needed for achieving one or several objectives of the Mission “Restore our Ocean and Waters”. The participation of relevant public bodies managing those areas and their communities as partners of the consortium is strongly encouraged. Project results are expected to contribute to all the following outcomes: Member States and Associated Countries are provided with cost-effective and innovative solutions to increasing riparian and coastal areas’ resilience to climate change, especially in waterfront cities and islands, contributing to reach the targets of the EU climate adaptation and water resilience strategies for 2030, but also supporting achievements of the EU biodiversity strategy for 2030, the Water Framework and the Marine Strategy Framework directives; Enhanced ecological functions of riparian and coastal areas including in waterfront cities and islands (e.g.: water quality improvement, pollution remediation, erosion control, morpho-dynamics and sediment transport, biodiversity conservation and restoration); Reduced vulnerability to climate change related risks (e.g.: lowering flood risks by increasing their natural buffer capacity; adapting to sea level rises and extreme events, and enhancing drought resilience by increasing groundwater recharge functions, carbon sequestration, reducing harmful algal blooms, etc.) with biodiversity co-benefits; Increased socio-economic benefits deriving from protecting and restoring riparian and coastal areas and from the remediation of pollution, as well as for recreational and touristic activities; Stakeholders and local competent authorities managing riparian and coastal areas, including in waterfront cities and islands (not limited only to those who are partners in the consortium), are engaged to implement and upscale innovative solutions that contribute to increasing resilience to climate change and water-related risks, including by strengthening synergies with their own programmes and resources and encouraging public and private investment.

Scope

Riparian and coastal areas play a critical role in local climate regulation and serve as the buffer regions between land and waterways, providing a wide array of important ecosystem services such as acting as natural barriers against storm surges, flooding, and erosion, filtering pollutants from the water, regulating floods, providing habitats for species and increasing soil health. sequestering carbon. Islands, which offer invaluable natural resources that support people, cultures and livelihoods, are particularly vulnerable to climate change. The proposal should build (when relevant) on previously developed or existing solutions by other projects, funded by EU and national programmes, in particular the European Union Framework programmes for Research and Innovation , the co-funded Partnership Water Security for the Planet (Water4All) as well as ERDF, INTERREG and LIFE programmes. Proposals are also encouraged to consider -- where relevant -- the services offered by European research infrastructures . The proposals should take in consideration the projects to be funded under HORIZON-MISS-2025-01-CLIMA-03: Demonstrating solutions to help hotspots in coastal regions to adapt to climate change. Each proposal should address only one basin/Mission 'lighthouse', which should be explicitly stated in the proposal, i.e.: 1. Atlantic and Arctic sea basin or 2. Mediterranean Sea basin or 3. Baltic and North Sea basin or 4. Danube River basin (including its delta and the Black Sea). Activities should be tailored to address regional/sea basin specificities, with strong and meaningful involvement of public administrations, including relevant island public authorities. The basins / Mission “lighthouses” include the river basins flowing into the respective sea basins. Proposals should: Test and demonstrate effective solutions in riparian and coastal areas including in waterfront cities and islands to achieve the Mission’s objectives and targets and to address resilience of communities living in those areas to relevant climate change impacts. Proposals are encouraged to have an emphasis on Nature-based Solutions, an integrated source-to-sea approach including land-sea interactions, transboundary actions and the regeneration of the blue economy; Show a significant replication potential by identifying areas and locations where the proposed solutions could be replicable. An action plan and roadmap needed for the replication and scale up of the solutions for improving resilience to climate change of islands and riparian and coastal areas are expected to be drawn up by the end of the project; Monitor the impacts and effectiveness of demonstration activities at a local scale.

What this means for cities and regions

Waterfront cities, islands and the public bodies that manage coasts and riverbanks; their participation as consortium partners is strongly encouraged. Topic budget €35.7 million; 4 grants expected; €8 million–€8.93 million per project. Opens 9 February 2027; closes 21 September 2027. Coastal erosion, sea-level and storm-surge monitoring rely on Sentinel imagery and Copernicus marine and climate data to set the baseline and track results.

Eligibility notes

Type of action for this topic

HORIZON Innovation Actions (HORIZON Action Grant Budget-Based).

Who can apply

  • Any legal entity (public body, private body, NGO, university, research organisation, SME, large company) established in an EU Member State (including Overseas Countries and Territories), or in a Horizon Europe Associated Country.
  • The list of Horizon Europe Associated Countries is maintained on the EU Funding & Tenders Portal.

Consortium rule for this topic

Proposals must be submitted by a consortium of at least 3 independent legal entities, each established in a different EU Member State or Horizon Europe Associated Country, of which at least one must be established in an EU Member State.

Co-financing rate

  • Research and Innovation Actions (RIA): 100% of eligible direct costs + 25% flat-rate indirect costs.
  • Innovation Actions (IA): 70% of eligible direct costs (100% for non-profit legal entities) + 25% flat-rate indirect costs.
  • Coordination and Support Actions (CSA): 100%.

The applicable Type of Action is indicated on the topic record in the Funding & Tenders Portal.

Restrictions and special cases

  • Natural persons not eligible except sole traders.
  • International organisations and the JRC are eligible.
