Summary

In this conference, Pascale Biron, a professor at Concordia University and co-director of the GRIL, explains the concept of river freedom space and its importance for river health and climate change adaptation. She begins with an introduction to hydrogeomorphology, emphasizing that rivers transport both water and sediments, and that a balance between these is crucial. She illustrates how human interventions like channel straightening and bank stabilization disrupt this balance, leading to erosion and loss of biodiversity. Biron presents the concept of river freedom space as the sum of mobility space (where meanders can migrate) and inundation space (floodplains), including riparian wetlands. She shows examples from Quebec and elsewhere, and highlights the role of beaver dams in creating diverse habitats. The talk concludes with a call to give rivers more space, allowing natural processes to restore ecosystems and improve resilience to climate change.
