Working Together Across Borders
Arena for Journalism in Europe supports collaborative journalism – journalists working together across geographical borders, and journalists working across professional borders with scholars, scientists, and with civil society.
We believe that collaborative journalism is crucial to knowledge sharing, critical thinking and political life in European societies. We build European networks, create cross-border meeting spaces, and spread the tools and experiences of collaborative projects.
The core activities of Arena are:

The Conferences
Planning and organizing Dataharvest – the European Investigative Journalism Conference (next May 28-31, 2026) and the Climate Arena Conference (next Oct. 10-11, 2025, in Budapest.).

The Networks
Facilitating open networks for information sharing to help journalists to collaborate across borders.

The Academy
Educating and knowledge sharing about cross-border collaborative journalism through training, publishing articles, speaking, developing educational materials and advising on cross-border collaborative journalism education.
