## Summary

The Water4All Joint Call funds transnational water security research consortia through FWO, offering approximately €350,000 per Flemish project over up to three years. Applicants must form consortia of at least three entities across three EU member states, with Flemish researchers leading or co-leading the work. This periodic call is open to fundamental and applied research under FWO's FO and SBO schemes, excluding spin-off projects.

## Who should apply

- Flemish researchers based at universities or public research institutions eligible under FWO funding rules
- Research teams leading or co-leading an international consortium of at least three entities across three EU member states
- Projects addressing water security through fundamental or applied research (FO or SBO track)
- Researchers ineligible under spin-off project provisions

## Key dates

- Periodic calls organised by the Water4All partnership; check Water4All and FWO websites for next deadline
- Up to 36 months project duration

## Tips for applicants

- Consortium composition is gating: ensure you have three institutional partners in three different EU member states identified and committed before drafting the proposal.
- FWO ranks proposals via a transnational panel after you submit to the call secretariat; align your water security framing with FWO's priority areas to strengthen your competitiveness.
- Verify your project pathway (FO vs. SBO) early; SBO spin-off projects are explicitly ineligible, so confirm eligibility with FWO before investing writing effort.
