The European biodiversity partnership Biodiversa+ has launched the call “Novel ecosystems: biodiversity, socio-ecological consequences and future trajectories” for international research projects on novel ecosystems, biodiversity, and socio-ecological transformations. The call offers opportunities for citizen science through the involvement of citizens and stakeholders in biodiversity monitoring, data collection, and the co-creation of inclusive and equitable pathways towards nature-positive futures. Deadline: 10 November 2026.

AI researchers and innovators can receive lump-sum funding of up to €30,000 through the amai! Impact Booster for activities that engage citizens in AI research and innovation. The funding supports citizen participation and outreach, thereby fostering greater societal dialogue, engagement, and acceptance of technology. This support is complementary to existing Flemish research and innovation grants.

The Global Conference on Citizen Science for Health (CS4H) 2027 invites abstracts on the societal impact of citizen science in health, highlighting multidisciplinary collaboration between citizens, patients, researchers, and policymakers. Contributions can take various formats, including oral presentations, posters, or interactive sessions, addressing themes such as health inequality, ethics, and co-creation of data. deadline: not specified

Deadline: 15 September

BMC Zoology invites submissions to a special collection on Citizen science for zoological research, focusing on how public participation enhances wildlife monitoring, conservation, and data integration. The call welcomes studies on community engagement, evaluation of citizen science initiatives, and their impact on biodiversity research and awareness. Deadline: 11 November 2026.

The European Commission invites cities and partners to design and host Science Comes to Town 2029, a one-year programme connecting citizens and science through participatory and inclusive events. The programme includes EUCYS and EU TalentOn and strongly encourages citizen science approaches and community engagement.

Deadline: 11 March 2027

call: HORIZON-WIDERA-2027-05-ERA-03

The European Commission invites proposals that develop innovative citizen science and science communication approaches, focusing either on engaging young people in research or scaling national engagement initiatives to the ERA level. This call is highly relevant for organisations aiming to co-create new methods with diverse publics and reinforce trust in science.

deadline: 11 March 2027

call: HORIZON-WIDERA-2027-05-ERA-04

This call focuses on projects related to small‑scale aquatic food production (fisheries, aquaculture, recreational fisheries) that develop new methods and digital tools to measure their ecological and socio‑economic impact. Citizen science (such as citizen observations, local knowledge, and participatory data collection, e.g. via apps or social media) is highlighted in the call text.

Deadline:23 September 2027

Call: HORIZON-CL6-2027-02-FARM2FORK-06

The European Commission launches a Horizon Europe call for living labs on invasive alien species, bringing together researchers, authorities, citizens and other stakeholders to co-create solutions for detection, monitoring, control and policy. Citizen science (e.g. public reporting, eDNA, participatory data collection) and FAIR open data are key to better understand impacts on biodiversity, ecosystem services and human health.

Deadline: 22 September 2027 

Call: HORIZON-CL6-2027-01-BIODIV-04

Horizon Europe is the EU research and innovation program for the 2021-2027 period. It focuses on 5 main missions.
Citizen science calls can be found in the Funding and Tenders portal. 

Furthermore, Citizen Science may also be used as a research method in other calls under the European funding programs.

Besides taking advantage of funding opportunities earmarked for citizen science, you can implement citizen science as a research method in your project application through 'regular' funding channels such as FWO (Research Foundation - Flanders), VLAIO (Flanders Innovation & Entrepreneurship) and BELSPO (Belgian Science Policy Office).
