On Monday morning, scientists from the European Molecular Biology Laboratory (EMBL) and the University of Luxembourg collected water and soil samples from the Moselle river near Machtum. Their aim: to gain a clearer picture of the impact human activity has on river health. One key focus is how different microorganisms respond to environmental changes, as Professor of Ecosystem Biology Paul Wilmes explains.
He states that this is their first time conducting a truly system-wide, integrated analysis to create a comprehensive data set. The goal is to identify future milestones, such as new approaches to managing antimicrobial resistance. "The crucial point is that general pollution leads to an increase in antimicrobial resistance", Wilmes cautions, the environmental dimension of which remains largely unexplored.
The research team is not looking at these challenges in isolation. Their study covers a range of interconnected issues, including the effects of climate change, environmental pollution, the spread of antibiotic resistance, and the decline in biodiversity. The objective is to analyse these developments not as separate phenomena, but to understand how they interact and influence one another.
Wilmes explains that this is not a one-dimensional issue; instead, there is a whole range of interlinked factors that they are trying to untangle with this programme. They aim to generate data that will inform decision-making processes, so that "rational decisions can be made when it comes to addressing these challenges", he adds.
The European project is also examining other rivers across the European Union, but the EMBL considers the Moselle an ideal region for this type of research. As a border river between three countries, its course is heavily shaped by industry, agriculture, and shipping, explains researcher Jan Korbel.
He adds that they aim to repeat these studies in the future and return to the same sites over time to reliably determine how environmental influences and a changing climate affect ecosystems.
