What's a lake worth? Measuring success and funding the future of lake restoration
Choosing where to begin: scaling up lake restoration across Europe
Most of Europe's lakes are still officially classed as failing – and yet the scientists who've spent decades beside these waters tell a more hopeful, more complicated story. So how do we actually know whether restoration is working? What gets lost when a single failing measure marks a whole lake as a failure? And, crucially, who is going to pay to bring our lakes back? In this third episode, we meet two researchers from the FutureLakes project who have spent years trying to measure success – not just in nitrogen and phosphorus, but in birdlife, swimming, jobs, carbon and euros. Lilith Kramer (Deltares) draws on a synthesis of six demonstration lakes to explain why real recovery is often hidden by EU scorecards, and why hope and complexity go hand in hand. Environmental economist Najla Kamergi (SEMIDE) makes the case for lakes' "bankability" – and asks what we risk when we put a price on nature.

Nearly half of Europe's lakes are failing to meet basic ecological standards – and with tens of thousands of degraded waters across the continent, there will never be enough money, time or attention to restore them all at once. So which lakes do we begin with? Who decides? And once the science is done, what keeps a lake healthy for the decades that follow? In this second episode, recorded at the FutureLakes midterm consortium meeting in Gdańsk, Poland, we travel to the restored Kartuzy lakes to explore the human questions at the heart of lake restoration: choosing, governing, and bringing people along. Project coordinator Laurence Carvalho (NIVA) makes the case for lakes as overlooked but vital ecosystems, and for a policy window now opening across Europe. Maeve McGovern (NIVA) introduces a new framework to help governments decide which lakes to restore first. And Åse Johannessen (Deltares) reveals why governance – trust, coordination, and who's invited into decision-making rooms – matters as much as any engineering.

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. futurelakes.eu ~ Episode image by Camilla H. C. Hagman
