Once straightened and constrained, l’Eau Blanche is learning to flow freely again.
Led by Natagora, this river restoration project in Wallonia[1] shows how working with nature can help address today’s intertwined climate and biodiversity challenges. By restoring the river’s natural meanders, the project slows the flow of water, revitalises wetlands, and recreates a rich mosaic of habitats where fish, birds, and plant life can thrive once more.
This transformation goes beyond ecology—it responds directly to the increasing risks of floods, droughts, and biodiversity loss.
By supporting this initiative, the Candriam Institute for Sustainable Development puts its environmental commitment into practice, in line with one of its core pillars: protecting natural ecosystems. Through such partnerships, the Institute turns conviction into action, helping to restore nature’s resilience while contributing to a more sustainable future for both communities and the environment.
Project’s Key Figures
- 1.6 km of watercourse before works, 2.4 km after works, representing an increase of 780 metres in channel length
- More than 100 shelters and refuges for fish
- 800 m² of spawning grounds (favourable for the reproduction of brown trout and European grayling in particular)
- More than 400 m of hedgerow planted
- 4 ponds created
