The International Commission for the Protection of the Danube River (ICPDR) successfully launched its webinar series “It Takes Two to Tango” on 28 April 2026, bringing together about 100 participants from across the Danube River Basin and beyond. This initiative seeks to address the growing challenges of water scarcity, pollution, and climate change that threaten both water resources and food security in the Danube River Basin.

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.
