Reduce flood risk

The Finnish River Management Association Virho

The Finnish River Management Association Virho (Virtavesien hoitohidstys Virho ry), was nominated for the Nordic Council Environment Prize 2022 with the theme of nature-based solutions. The Finnish River Management Association has the goal to revive and secure the living conditions of the entire water ecosystem in Finland. This includes fostering biodiversity and fish stocks in areas of flowing water. Virho has operated for more than 30 years restoring hundreds of kilometers of streams through building fish roads, rehabilitating streams and rapids, and deconstructing dams.

Room for the Rhine branches

flooded Rhine branches in the Netherlands

The aim of this case study is the creation of ecological flood retention by changing land use, reconnecting floodplains and change of sluice management in summer dikes. Floodplains are reconnected and side channels restored or their creation supported, with longitudinal main channel dams benefitting both shipping and nature.

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.

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...

Votlendissjóður - The Icelandic Wetland Fund

Votlendissjóður was established in 2018 with the goal to restore and reclaim wetlands in Iceland through cooperation with landowners, municipalities, the Icelandic state, companies, NGO’s and farmers. The fund provides finances, and in some instances equipment and personnel, to parties interested in restoring wetlands not used for cultivation or forestry. Alternatively, the Votlendissjóður themselves can foster wetlands and carry out restorations through approved methods and professionals. Volunteers monitor the effects of the wetland on birds, plants and other wildlife in the area. ...

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.

Removing dams in the Deba River, Spain

The hydro-geomorphology of the Deba River basin in the Basque country will be restored, mainly through dam demolition, restoring river morphology, connectivity and faunal permeability. Stakeholder interaction is being promoted, connecting local communities, institutions and governments. A main objective is to promote environmental education and the conceptualisation of nature-based solutions oriented restoration policies.

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...

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.

Erosion Protection with Nature-based Solutions in Norway

The Norwegian Institute for Bioeconomy will prevent erosion by strengthening slopes and edges with nature-based solutions (NbS). The aim is to improve local environmental conditions and increase water quality and biodiversity in streams and rivers.

In many creeks and streams, both large and small, erosion is a major problem. The problem arises as a result of various types of interventions in nature and is typically solved with stone and concrete - so-called grey solutions. But the grey solutions often have negative consequences on the local environmental conditions, water quality...

Multifunctional Wetlands in Åland

The Nordic Council of Ministers programme, Nature-based Solutions in the Nordic Region, is financing a project in Åland to improve four multifunctional wetlands for better water quality, sustainable food production, climate adaptation and increased biodiversity.

For several years, the drinking water from the Åland lakes and streams was assessed as insufficient and water samples showed a declining quality. This led the water supply company Ålands Vatten in 2015 to initiate research and an urgent new management plan to ensure a sustainable water supply. One study showed that...
