📢 The deadline is almost here! Don’t miss your chance to contribute to #ECSA2026 – Citizen Science Between Centre and Periphery, taking place at the University of Oulu, Finland.

#CitiObs is hosting three impactful sessions on how citizen science connects with data trust, validation, and participatory policy. We’re inviting submissions from researchers, practitioners, and citizen scientists.

🗓️ Submission deadline: 7 October 2025
🔗 Full programme & submission info: https://www.ecsa2026.ngo/programme/#17094

Earlier this month (September 4–5), #NILU hosted the IdeaLab on #Citizen Science for #Arctic Challenges at Framsenteret, Tromsø.

Researchers and experts from diverse fields, including architecture, biology, anthropology, and more, came together to share insights on how citizen science can support communities in the northern regions of Norway.

💡 The #workshop confirmed one thing: #collaboration across disciplines and with #communities is key!

💡Session: Panel - Citizen Observatories: #Data Awareness and Data Literacy at the Citizen–Policy–Research Interface.

We’ll share lessons from Urban ReLeaf, #GREENGAGE Project, #CitiObs and others on building shared data literacy, co-designing sampling, and ensuring citizen evidence is seen and heard by institutions.
