Strategic Policy Fit

This topic underpins the European Green Deal, the Climate Adaptation Strategy, the upcoming European Water Resilience Strategy and the Nature Restoration Regulation. Funded projects must generate demonstrable innovation that:

1. Assesses and manages the changing hydrological cycle at fine spatial scales.

2. Fosters water-resilient land use and natural water cycle restoration supporting biodiversity.

3. Improves cross-sector & transboundary catchment cooperation within the Water-Energy-Food-Ecosystem (WEFE) nexus.

4. Delivers basin-level water-use efficiency, rebalancing demand & supply and restructuring water governance/economics.

5. Enables policy makers to plan future-proof water infrastructure ensuring fair access to drinking water & essential uses.


Budget & Cost Rules

* Funding covers up to 70 % of eligible costs for for-profit entities (exceptionally 100 % for non-profit).

* Indirect costs reimbursed at 25 % flat-rate of direct eligible costs.

* No co-funding from other EU programmes for the same activities (no double financing).

* “Equipment” costing method: depreciation only.

* Large-scale demonstration expenses (pilots, living labs, digital twins, citizen science) are eligible if clearly linked to objectives.


Consortia Requirements

* Minimum: 3 independent legal entities from 3 different eligible your country, incl. at least 1 Member State.

* Multidisciplinary consortia are encouraged: hydrology, climate science, ecology, economics, social science, digital twins, satellite EO, governance.

* Joint Research Centre (JRC) may join as beneficiary.

* If using EO/PNNT services, proposals must exploit Copernicus and/or Galileo/EGNOS.


Intellectual Property & Open Science

* Mandatory Data Management Plan (DMP) with FAIR principles.

* Open Access to peer-reviewed publications.

* Exploitation strategy for foreground IP (freedom to operate, licensing, standardisation pathways).

🇪🇺 Strategic Advantages

EU-Wide Advantages & Opportunities for the Topic “Strengthening the resilience of water systems and water sector to climate and global socio-economic change impacts”


1. Single Market Access (450+ million consumers)

• Unlocks a unified demand for water-resilience solutions across 27 Member States, enabling rapid commercial uptake of tools for forecasting, allocation and infrastructure management.

• Harmonised public-procurement rules (Directives 2014/24/EU & 2014/25/EU) simplify the sale of smart sensors, nature-based retention solutions and digital water services to utilities and municipalities EU-wide.

• Sector coupling (WEFE nexus) opens parallel markets in agriculture, energy, tourism and industry, multiplying revenue streams for successful demonstrators.


2. Cross-Border Collaboration & Knowledge Exchange

• Grant explicitly requires demonstrations in diverse European regions, favouring multi-country consortia that pool hydrological data, best practices and complementary expertise (e.g. Mediterranean drought management + Nordic flood control).

• Facilitates creation of transboundary river-basin pilot sites (Danube, Rhine, Douro, Sava, etc.), directly addressing shared water risks that no single Member State can solve alone.

• Participation of the Joint Research Centre (JRC), Copernicus service operators and Destination Earth initiatives guarantees access to cutting-edge EU datasets and modelling capacity.


3. Alignment with Flagship EU Policies

• Directly serves the European Green Deal, EU Climate Adaptation Strategy, Nature Restoration Regulation and forthcoming European Water Resilience Strategy.

• Contributes to the Digital Europe Programme via integration with Destination Earth digital twins and Copernicus data layers.

• Supports Biodiversity Strategy 2030 and Farm-to-Fork by safeguarding ecological flows and enabling water-efficient agriculture.


4. Regulatory Harmonisation & Standard Setting

• Research outputs can feed into the Common Implementation Strategy (CIS) of the Water Framework Directive, accelerating EU-wide adoption of new efficiency indicators and allocation rules.

• Early engagement with standards bodies (CEN/CENELEC, ISO/TC 224) positions consortia to influence European standards for smart water metering, remote sensing and nature-based solutions, easing later market entry.


5. Access to Europe’s Innovation Ecosystem

• Leverages 3,400+ Horizon Europe beneficiaries, 300+ EIT Climate-KIC & Water-KIC partners, and 200+ Water4All partnership members for rapid dissemination and exploitation.

• Facilitates recruitment of top talent through cross-border secondments, Marie Skłodowska-Curie actions and Erasmus+ mobility.


6. Funding Synergies & Blending Opportunities

• Results can be up-scaled with:

• EU Mission “Adaptation to Climate Change” demonstration regions (up to €360 m).

• LIFE programme for large-scale nature-based retention investments.

• Connecting Europe Facility (CEF2) for trans-European water infrastructure, including data backbones.

• ERDF & Cohesion Funds for regional deployment in convergence regions.

• InvestEU and EIB “Water Sector” windows for blended finance and guarantees.

• Alignment avoids double-funding while maximising cumulative impact.


7. Scale & Impact Potential

• Pan-European pilots generate statistically robust evidence across varied climates (Atlantic, Continental, Mediterranean, Boreal), proving generalisability and supporting EU-wide policy uptake.

• Common open-source toolkits and interoperable data layers enable plug-and-play replication by other river basins, accelerating market growth beyond the project lifetime.

• Improved water resilience underpins €2.6 trillion of annual EU GDP that depends on secure water supply (agri-food, pharma, semiconductors, renewables), providing macro-economic justification for further investment.


8. Strategic Value of Operating at EU Scale

• Addresses hydrological cycles that ignore national borders, ensuring solutions match natural systems rather than administrative limits.

• Consolidates fragmentary monitoring networks into a coherent European Observing System, reducing uncertainty and data costs for all users.

• Creates a first-mover advantage for European SMEs & utilities in the growing global market for climate-resilient water management (projected €1 trillion by 2030).


Bottom Line: By exploiting the EU’s single market, regulatory alignment, world-class research networks and blended-finance toolbox, projects under this call can achieve faster innovation, broader deployment and higher socio-economic returns than would ever be possible through isolated national initiatives.
