Emscher: NbS for dykes along Europe's most expensive river

For almost 30 years, until 2022, the Emscher river, flowing through Germany's larges metropolitan region, the Ruhrgebiet, has been restored from a heavily sewage loaded system to a vital river. As the river is located in a densely populated area, dykes and other flood protection structure are necessary at least in some part. This case study aims at transitioning the land use on these dykes and near river areas towards extensive meadows. It is a step towards creating synergies between river maintenance and nature protection.

This case study is one of 17 that are part of the EU...

Peatlands of Bosnia and Herzegovina: Neretva-Trebisnjica and Hutovo Blato

Peatland sites within carstic catchments in Bosnia and Herzigovina are to be restored through channel restoration and rewetting, thereby protecting these hotspots for (endemic) biodiversity. The case study aims at achieving an amicable transition from the current heavy hydropower usage and peatland extraction to more near-natural, healthy ecosystems.

This case study is one of 17 that are part of the EU Horizon2020 project MERLIN - Mainstreaming Ecological Restoration of freshwater-related ecosystems in a Landscape context: INnovation, upscaling and transformation

Kampinos National Park

The wetlands in Kampinos National Park, Poland, are restored in order to slow water runoff and protect Natura2000 habitats as well as species.

Kristianstads Vattenrike - Sweden’s oldest UNESCO biosphere reserve

In 2005, the UN agency UNESCO approved Kristianstads Vattenriket as a biosphere reserve covering 100 000 ha, and one of 700 in the world. This means Kristianstads Vattenrike is an internationally recognized model for sustainable development. The Vattenrike encompasses two thirds of the municipality of Kristianstad, with the goal to “preserve, develop and support the landscape's values”.

Nature-based solutions have been key for protection against droughts, floods, and preservation of the area, as well as nutrient leakage into the Baltic Sea.

The areas in Vattenriket include...

The Nabben Multifunctional Wetland in Åland

A newly built multi-functional urban wetland in the Nabben area, Åland, recently won the Nordic Council Environmental Prize 2022 focused on nature-based solutions. The wetland, which was finished in 2019 and lies adjacent to the coast, aims to increase the biodiversity in the area and contribute to the improvement of the water quality of the Baltic Sea by reducing nutrient runoff. Furthermore, it is used as an area for recreation, social cohesion and education for the city residents.

There are several components to the Nabben wetland ecosystem. The first separates the microplastics...

Beaver re-introduction in Sweden

A truly nature-based solution is implemented by allowing beavers to spread into desired areas, letting them restore degraded wetlands and small streams and ditches as well as forest landscapes.

SABICAS - Haldenvassdraget

SABICAS (SAfeguard BIodiversity and improve Climate Adaptation in catchment areas under pressure: tools and Solutions) aims to provide tools and knowledge needed to quantify the benefits and co-benefits of nature-based solutions. The goal is to facilitate dialogue and decision making among stakeholders and managers. SABICAS will engage with all key catchment stakeholders through several activities, including workshops and living labs.
