Explore how to best maintain existing areas of edible urban greenery - and integrate new ones - into the area, as well as how these green spaces can be used to connect the existing neighbours with the new ones by providing spaces for community gardening, togetherness and knowledge exchange.


Restoring Danube floodplains in Romania

Garla Mare Romania

Former wetlands adjacent to the river are being reconnected to demonstrate the benefits of re-wetting /reconnection to the natural flood pulse of the Danube River in order to enhance the benefits provided to nature and local communities.

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.


Climate change adaption and the river Seest Mølleå

The center of the city Kolding is frequently under threat from flooding due to heavy or prolonged precipitation events. Located at the bottom of a river valley, the municipality has initiated many climate-proofing projects to mitigate flood risks. One such project, initiated by Kolding municipality and the utility company Bluekolding, concerns the river Seest Mølleå. The nature-based climate adaptation project cost a total of 3,5 mio. DKK, and was inaugurated in November 2021 after 5 months of construction. 

When heavy prescriptions occur in the large catchment area outside the city...


Kampinos National Park

Kampinos National Park (c M.Szajowski & A.Andrzejewska)

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

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.


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...


Removing dams in the Deba River, Spain

Dam removal in the Deba River

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...

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...
