The ICPDR’s 5th Joint Danube Survey (JDS5) is pushing the boundaries of what river science can do. And the first preliminary results are beginning to reveal a rich and complex picture of one of the world's most studied rivers.

Barely a month after hosting the 24th ICPDR Standing Working Group Meeting in Uzhhorod, Ukraine, brought the Danube community together again. On July 24th, Ukraine hosted its 6th National Participation Day in Odesa as part of the EU Strategy for the Danube Region (EUSDR). The event highlighted the alignment between the priorities of Ukraine’s ICPDR Presidency and the country’s path towards EU membership.

Have you ever wondered what secrets a single drop of water from the Danube River might hold? At this year’s Long Night of Research on 24 April 2026, the ICPDR invited visitors to find out at the Vienna International Centre (VIC).

The ICPDR is pleased to share a first glimpse into the microbiological findings emerging from the Joint Danube Survey 5 (JDS5) — the world’s largest river basin monitoring programme carried out on a single river system. While full results will only be available once all samples from the 108 sampling sites have been analysed, early data from the microbiology component show encouraging trends across the entire Danube Basin.

A remarkable discovery has been made in the Drava River: an angler in Croatia recently caught a ship sturgeon (Acipenser nudiventris), a species long believed to be extinct in the Danube River Basin. Measuring 176 centimetres and weighing 35 kilograms, the fish was safely released back into the river after being identified by local authorities. The sighting is encouraging as it marks the first confirmed record of the species in many decades.

Bucharest, Romania – Nine countries along the Danube River have joined forces to protect some of Europe’s most endangered species: the sturgeons. On 9–10 July, thirteen project partners and strategic allies – including national ministries, universities, NGOs and research bodies – gathered in Bucharest to launch “MonStur in the Danube,” a new cross-border effort to monitor and protect these ancient migratory fish.

The 5th Joint Danube Survey (JDS5) has reached a significant milestone by incorporating citizen science into its outreach activities for the first time. Under the Motto "Let's Go Sampling Together", this activity Coordinated by the Joint Research Centre (JRC) of the European Commission and supported by the International Commission for the Protection of the Danube River (ICPDR), engaged schools across the Danube Basin in a collaborative effort to monitor and protect the river's ecological health.

On 7 July 2025, the Vienna International Centre’s Rotunda came to life with creativity, collaboration, and a shared appreciation for one of Europe’s most iconic rivers. Under the title “Surface & Substance: Exploring the Danube Through Science and Art,” the ICPDR launched a special week-long exhibition celebrating the power of both scientific investigation and artistic expression in protecting the Danube.
