“When a river is alive, it has a sound,” said Angela Ortigara, a senior adviser at WWF Netherlands. “You hear it trickling down the rocks. You see vegetation around it. It’s this flow of life.”
And “across Europe, that sound is now beginning to return,” said CNN. The environmental coalition Dam Removal Europe has calculated that a record-breaking 603 dams were removed across the continent last year as countries embarked on a “broader reassessment of how rivers function in an era of climate extremes.”
The removals allow waterways to “resume their natural course,” and they are part of a “global trend to restore rivers to help wildlife thrive,” said The Guardian. The damming of rivers “disrupts ecosystems, hinders the transport of sediments” and is believed to have contributed to a 75% fall in Europe’s freshwater migratory fish population over the past 56 years.
Not everyone is on board, though. Some farming groups and policymakers have criticized the wide-scale dismantling of dams and water barriers, raising concerns about potential impacts on land use and rural livelihoods. The presence of dams could slow the spread of invasive species, while barrier removals may allow new threats to travel from one part of a river to another, according to a study published last year.
But with “careful preparation, monitoring and long-term management, these risks can be minimized,” said Ellen Dolan, a biologist at Queen’s University Belfast and the lead author of the riverine barrier removal study, to The Guardian.
