Beneath the calm surfaces of Europe’s lakes, a quiet crisis is unfolding.

Once-clear waters are impacted by pollution, algae blooms and habitat loss, with nearly half of Europe’s lakes now failing to meet basic ecological standards. In this first episode of the Future Lakes podcast, we explore what’s gone wrong – and how innovation is opening new pathways to recovery.

The episode introduces FutureLakes, a three-year Horizon Europe project coordinated by the Norwegian Institute of Water Research, which is rethinking how lakes are restored across the continent. Moving beyond business-as-usual approaches, the project treats lakes as living laboratories, combining science, nature-based solutions, circular economy thinking and community engagement.

We hear from researchers behind a major global review of innovative lake restoration methods, led by Laura Härkönen of the Finnish Environment Institute. Drawing on more than 1,500 scientific studies and expert insights, the review reveals why traditional measures have fallen short and highlights promising new approaches that work with natural processes – from reducing pollution at source to recovering nutrients locked in lake sediments.

The episode then explores two contrasting demonstration sites: the Marker Wadden nature islands in the Netherlands, where biodiversity has rebounded at scale, and Denmark’s Lake Ormstrup, where nutrient-rich sediments are being removed and reused in agriculture.

Together, these stories show that restoring Europe’s lakes is possible – but it requires time, ambition and collaboration. Tune in to find out how FutureLakes will drive this process forward in the coming years.
