As environmental challenges intensify across Europe, addressing water quality, biodiversity loss and climate change is more important than ever. From analysing Europe’s rivers and advancing climate change models to optimizing agricultural water use and spearheading conservation efforts, LIST is at the forefront of shaping sustainable strategies to empower policymakers and industries to act with precision and foresight, ensuring a resilient future for ecosystems and communities alike.

Assessing Europe’s rivers: progress and ongoing challenges
Top Story
LIST contributed to a major study published in Nature Ecology and Evolution, analysing water quality and biodiversity in European rivers.
The findings showed that while ecological conditions improved after the 1990s, progress has since stalled, with 60–80% of rivers still failing to achieve good ecological status.
In Luxembourg, LIST’s long-term monitoring efforts confirmed these trends. The study also revealed a complex relationship between water quality and biodiversity, highlighting the need for better metrics and baseline data. As pressures like climate change and pollution persist, LIST’s research provides key insights to inform future river management policies.
Sarah Vray, Senior R&T engineer, stated:
"Our research clearly shows that improved water quality doesn’t automatically translate into better biodiversity outcomes. Biodiversity responds in complex and sometimes contradictory ways, depending on the metrics we use and the scale we examine. That’s why we need to move beyond a single-indicator approach and adopt more nuanced, multi-metric frameworks to truly understand ecological health. At LIST, we’re committed to supporting evidence-based policy with robust data, helping ensure that biodiversity goals in Europe are grounded in scientific reality rather than oversimplified assumptions."
