Flood peak reduction

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.


Restoring Danube floodplains in Austria

Riverbank restorations are implemented on a stretch of approximately 800m shoreline of the Danube to increase lateral river-floodplain connectivity and the functioning of the floodplain as an ecosystem. The aim is to reach a good ecological status of the river as well as good navigation status. The case study works with an adaptive management process and adresses multiple pressures (ecological deficits, security of navigation, riverbed deepening, flood protection).

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.


Beaver re-introduction in Sweden

Beaver dam 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.

Kvorning re-wetting

Kvorning area in Denmark

Climate gas emission will be reduced and carbon sequestration will be stimulated by rewetting this area along the Nørreåen stream in Denmark. This restoration will preserve valuable Natura2000 habitats and endangered plant species, while at the same time making land consolidation efforts to support landowners.

This case study is one of 17 that are part of the EU Horizon2020 project MERLIN.


Biodiversity in Urban and Coastal Areas in Iceland

The Nature-based solutions in the Nordic region programme has allocated 650,000 DKK to a pilot project in Iceland that aims to increase biodiversity in Reykjavík.
 
Grasagarður Reykjavíkur is the name of the outdoor collection of living plants located in the capital of Iceland. The park conserves some 3000 plant species in eight plant collections. The collections give an idea of the enormous diversity of vegetation in the northern temperate zone.

Among the staff are Hjörtur Þorbjörnsson and...


Territorial Ordering Plan (POT) of Bogotá 2022-2035 "El reverdecer de Bogotá"

On September 2021, the mayor and the District Planning Secretary presented the proposal for the Territorial Ordering Plan (POT ) 2022-2035. This POT responds and involves the Sustainable Development Goals in land use planning. Based on these areas, the plan incorporates on four pillars, including sustainable mobility, greening, a care system for women and sustainable economic economy.


INVENTORY OF NATURE-BASED INNOVATIONS

Inventory of nature-based innovations

The Erasmus+ project „Nature-Based Innovations for Urban Forest and Rainwater Management” supports communities and local authorities in combating climate change through the identification of good practices and the dissemination of innovative solutions and manuals addressed to local authorities, stakeholders, and associations to improve policies and practices to  counter climate change from an environmental, social, and economic point of view.


Watershed-scale impacts of stormwater green infrastructure on hydrology, nutrient fluxes, and combined sewer overflows in the mid-Atlantic region

Use of vegetation in urban areas in the Mid-Atlantic watersheds of Washington DC, Montgomery County and Baltimore County MD, has reduced flooding and nutrient runoff. The ‘stormwater green infrastructure’ in these municipalities includes green roofs, bioswales, rain gardens and stormwater ponds. By increasing infiltration and groundwater recharge, and/or evaporation, they reduce the volume of run-off that can contribute to floods.


Using semi-natural meadow vegetation for restoration of river revetments: A case study in the upper reaches of the Yangtze River

This study aimed to use a semi-natural meadow as an ecological restoration tool for the optimisation of ecosystem services and landscape attractiveness of river revetments. River revetments combine bank reinforcement with greening and can resist flood washing and provide waterfront space for human activities; thus, it has become a key functional unit in riparian ecosystems used to foster ecosystem services such as the interception and filtration of polluted surface water, habitat for organisms and aesthetic beauty.
