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.

This week, the International Atomic Energy Agency (IAEA) hosts its 69th General Conference, with this year’s Scientific Forum themed Atoms for Water. The event, running from 16–17 September 2025, brings together global experts to explore how nuclear and isotopic techniques can address water scarcity, climate resilience, and sustainable management.

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.

The Danube Strategy Priority Area on Water Quality (EUSDR PA4), together with the International Commission for the Protection of the Danube River (ICPDR) as co-conveners, are pleased to announce an upcoming online workshop on sewage sludge management, taking place on 20 June 2025, from 10:00 to 13:00 CEST.

The Joint Danube Survey 5 (JDS5), the world’s most comprehensive investigative surface-water monitoring effort, will officially kick off on 1 July 2025 in Vienna. This large-scale scientific survey will bring together experts from 14 countries to assess the health of the Danube River and its major tributaries.

The project involves 15 partners from 8 countries and aims to restore and conserve 34 islands from Germany to Romania. With the support of the EU Commission, the International Commission for the Protection of the Danube River, and the Ramsar Convention, the LIFE WILDisland project is set to become a great example of transboundary cooperation.

In the wake of what has been declared the nation's 'worst-ever natural disaster,’ more than 70% of Slovenia's territory, predominantly situated in the Danube River Basin, has been severely affected by extreme flooding. The scale of this catastrophe has led to billions of Euros in damages and a tragic loss of lives.

Despite the EU's advanced waste management and ambitious recycling objectives, studies still indicate the presence of macro and microplastic pollution in EU rivers. The Tid(y)Up project focuses on improving water quality and reducing plastic pollution in the Tisza River, which is long considered one of Europe’s most heavily contaminated rivers.
