Research and monitoring are crucial because the Mediterranean Sea is undergoing a profound shift in biodiversity, with species unsuited to new climate conditions declining, leading to unknown new ecosystems. This change is driven by multiple factors, including human activities that introduce alien species through events like the Suez Canal opening or ship ballast water. Citizens can help monitor biological invasions by reporting observations to the scientific community. While eradication at sea is difficult due to the ocean’s vastness, increased public awareness is needed to challenge unsustainable development models. On land in Spain, climate change also causes intense heatwaves and water stress, threatening Mediterranean forests and leading to altered life cycles in plants and animals, such as migration and parasite expansion.

PULSE is an initiative for cross-border collaborative journalism in Europe co-funded by the European Commission under Grant Agreement n. PO 4500158093.

PULSE is an initiative coordinated by OBCT that has been promoting intensive journalistic cross-border collaborations in Europe since 2024. Its main aim is to help strengthen the European public sphere by reporting on and telling stories from new and diverse perspectives.

At the heart of PULSE are 10 leading national news outlets (Delfi – Lithuania, Deník Referendum – Czechia, Der Standard – Austria, EfSyn – Greece, El Confidencial – Spain, Gazeta Wyborcza – Poland, HotNews – Romania, HVG – Hungary, Il Sole 24 Ore – Italy, Mediapool – Bulgaria) and three transnational organisations, including OBCT , n-ost and Voxeurop .

Additional outlets and journalists are involved as associate partners, including EUobserver , Føljeton (Denmark), H-Alter (Croatia), Levila (Estonia), Rubryka (Ukraine), and The Journal Investigates (Ireland).

PULSE is driven by a sort of virtual transnational newsroom made up of journalists from all the publications involved. It collaboratively produces new journalistic content on European issues on a daily basis, coming in many different languages. The editorial output amounts to over a thousand publications per year, mostly in article form.

PULSE also runs 4 thematic networks open to any European journalist interested in crucial issues such as EU enlargement, relations between the EU and other global powers, the EU’s green transition, or media and the information society. These networks function as online communities and periodically publish calls for pitches.
