Upscaling knowledge from WaterCoG - Visit from Sweden to Denmark

25 June 2018 - Published by Alistair Maltby
12th-13th June Danish Partners in WaterCoG, SEGES and Aalborg Municipality held a workshop for a group from Sweden concerning wetland restoration, drain filter solutions, catchment officers and environmentally friendly maintenance of small rivers and streams.

The workshop was held as part of the WaterCog project including the intention to reach outside project partners. Besides people from pilots within the WaterCoG project, there were also attendances from Falkenberg Municipality, LRF (Federation of Swedish Farmers), Länsstyrelsen Östergötland (Regional authority).

The workshop focused on wetland restoration of larger wetlands. The Danish tradition for larger wetland restoration goes more than 30 years back. The biggest restoration project is 2000ha, but usually several hundred ha. It often takes several years to finish a project and the governance set up for the project was presented together with the very important land consolidation process that takes a key role.

Environmental maintenance of smaller streams and rivers have been part of the Danish legislation since 1983 and since then, a lot of new methods have been developed. In this workshop we focused on how to cut weed in the streams in a way that over the years would transform straight channels into meandering streams with high biodiversity.

Finally, we focused on drain-filter solutions and the importance of the new governance structure in Denmark where catchment officers play an important role in finding and implementing these new solutions.
