Harnessing the potential of natural processes in freshwater restoration can create significant ecological, social and economic benefits, according to a major new report.

Researchers from the MERLIN project analysed restoration monitoring data from eighteen rivers, streams and wetlands across Europe to assess the impacts of so-called ‘nature-based solutions’ on the environment and society. Such approaches aim to help amplify natural processes to benefit both people and nature. For example, a healthy wetland can help filter water pollution and buffer floodwaters, whilst planting so-called ‘riparian zones’ of trees and other vegetation along river banks can help provide valuable biodiversity habitat, keep water bodies cool, and lock up carbon to help mitigate climate change.

The new report explores the impacts of a diverse range of European freshwater restoration strategies using nature-based solutions. These include peatland rewetting, beaver reintroduction, floodplain restoration and reconnection across a variety of landscapes. The results show that such restoration approaches can generate significant benefits for nature and society. In particular, many of the impacts support the goals of the European Green Deal, which aims to support climate neutrality, sustainable economies and healthy, diverse ecosystems across the continent.

In this podcast, we hear from two MERLIN researchers behind the new report: Laura Pott from the University of Duisburg-Essen, and Axel Schwerk from the Warsaw University of Life Sciences. Laura and Axel cover a range of topics including how to monitor the impacts of nature-based solutions in complex landscapes across Europe, the importance of engaging stakeholder groups around an ecosystem, and the value of Theory of Change approaches in helping map how a restored landscape might develop over time.

Restoring our natural ecosystems is a task that is never really finished: science progresses; governments change; technology advances; society shifts; funding pots appear and disappear. And all the time, our rivers, lakes, streams and wetlands are a constant; their fate determined by the choices we make about them. In a time of rapid ecological loss and the ongoing climate emergency, it can be hard to think hopefully about the future of our ecosystems.

In this podcast we hear from four inspirational young scientists who are helping restore Europe’s freshwaters, and with it, hope for the future of our natural world. The four scientists all work on the EU MERLIN project, but each have their own research focus. They are Miriam Colls Lozano from the University of the Basque Country, Andrea Schneider from the University of Duisburg-Essen, Viviane Cavalcanti from DELTARES and Joselyn Verónica Arreaga Espin from BOKU.

We hear about the challenges of bringing disparate communities together through freshwater restoration, fostering exchange and collaboration between different communities, thinking creatively about funding restoration in the future, and strategies for bringing the public and policy makers on board with ambitious restoration programmes. The thread that runs through all these themes is the need for good communication in fostering positive change for the future.

In this podcast we take a behind the scenes look at environmental restoration in Europe on the cusp of what will likely prove to be a transformative year. First, we find out about the EU’s big environmental policy, the Green Deal, then about the ambitious new Nature Restoration Law adopted last year. We then hear from four EU restoration projects about the challenges of planning, financing and carrying out restoration on freshwaters, forests, wetlands and coastlines across the continent.

Podcast host Rob St John speaks to Colombe Warin from the European Commission, Shane McGuinness from WaterLANDS, Agustín Sánchez-Arcilla from REST-COAST, Elisabeth Schatzdorfer from SUPERB and Sebastian Birk from MERLIN to get the inside story on restoring Europe's landscapes.

Four key themes emerge around contemporary restoration in Europe: the use of nature-based solutions; the importance of bringing communities and stakeholders together; the challenges of financing ambitious restoration projects; and the need to upscale restoration activities from individual sites to entire landscapes and watersheds.
