The Freshwater Knowledge Exchange Network is an interdisciplinary initiative focusing on advancing the restoration of free-flowing rivers across Europe. It operates in accordance with the goals of the 2030 EU Biodiversity Strategy's target of restoring at least 25,000 kilometres of free-flowing rivers, as adopted in the legally binding Nature Restoration Regulation (Article 9). The restoration of free-flowing rivers presents a complex challenge that requires the integration of scientific research with practical policy-making. It is particularly pressing as it addresses not only the conservation of freshwater biodiversity and the maintenance of natural ecosystem functions, but also achieving the ambitious targets laid out in major EU policies such as those mentioned above.
The issue of river connectivity is a perfect example of a multifaceted problem where ecological, hydrological, social and economic dimensions all interact, a reminder that effective restoration goes far beyond simple technical fixes. Accomplishing this is not straightforward as it involves navigating conflicts among various water uses, including energy, agriculture, transportation and flood control. Our approach involves a careful review of current policies and collaborative networks alongside the development of actionable short- and medium-term strategies designed to bridge existing legislative and operational gaps. Another essential part of our work is establishing a clear and uniform framework for understanding key concepts like free-flowing rivers, barriers and reference areas. Having such a common language is vital for bringing together all stakeholders, scientists, policy-makers and society at large as well as for ensuring that the scientific approach for the restoration efforts is aligned with broader policy goals. By doing so, we help transform isolated pilot projects into a well-connected network of initiatives that can have a large-scale, lasting impact on conservation.
