MERLIN Podcast Episode 1: introduction and floodplain restoration on the Rhine Delta

September 9, 2022

This week we’re delighted to bring you Episode 1 of the new MERLIN podcast. As we’ve covered in recent months, MERLIN is a major European Union funded project which is investing millions of Euros to help mainstream freshwater restoration across the continent over the coming years.

This podcast follows the MERLIN project in this journey. It offers a behind the scenes look at some of the continent’s most ambitious freshwater restoration projects carried out through cutting-edge aquatic science and conservation.

In July 2022 podcast host Rob St John travelled to the Netherlands to meet MERLIN practitioners working on the project’s large river restoration sites.

Over a number of hot, sunny days the team explored floodplains across the Rhine Delta which had been restored through a major project called Room for the River. Started in 1995, Room for the River worked to reconnect the Rhine with its floodplains, which had become isolated through the construction of dikes and levees. By making room for the river to periodically inundate its floodplains, new spaces for biodiversity habitat, carbon storage and recreation have been brought back to the Rhine catchment.

Walking along the banks of the Rhine, Rob speaks to restoration practitioners about their work, and catches up with MERLIN coordinator Sebastian Birk to hear about what the project hopes to achieve.

You can also listen and subscribe to the podcast on Spotify, Amazon, and Apple Podcasts. Stay tuned for Episode 2 in the coming weeks.

Freshwater Fact Cards: drawing attention to special freshwater species

Freshwaters are some of the most biodiverse yet highly threatened ecosystems in the world. As conservationists have repeatedly highlighted recently, the freshwater biodiversity crisis receives significantly less attention and support than that on land, or in the seas.

Part of this shortfall in attention is due to the nature of freshwater environments. Rivers, lakes, streams and wetlands can often obscure the wildlife they support below the water’s surface. This can make it hard not only to notice their richness, but also any ecological declines.

As a result, highlighting important – but often overlooked – freshwater species has become a key advocacy approach for many conservationists in recent years. In some cases, this approach tallies with ecological theory, which suggests that the conservation of particular ‘umbrella species’ can benefit the health of the wider ecosystem.

A new series of illustrated cards highlights twenty freshwater species that deserve special conservation attention. Scientists from IGB, Berlin and the Alliance for Freshwater Life have curated the project to spotlight species which are often inconspicuous, or found in remote regions, but are vital for freshwater conservation efforts.

“We chose the twenty species for two reasons,” says project curator Dr. Fengzhi He from IGB. “First, some are considered charismatic and hold the potential to function as flagship umbrella species to enhance freshwater conservation. The selected freshwater megafauna species such as European sturgeon, arapaima, Amazon river dolphin, common hippopotamus, gharial, Chinese giant salamander fall under this category. These are also species targeted in the Freshwater Megafauna Futures project.

“Most of these freshwater megafauna species are threatened, and the Chinese paddlefish has been officially listed as Extinct by the IUCN Red List,” continues Dr. He. “Second, we included species that are closely studied by IGB researchers. Some of these species may be smaller but have important ecological roles in local ecosystems or are key model organisms in freshwater research.”

The Freshwater Fact Cards highlight fascinating information about each of the featured species. For example: How do arapaima breathe? How deep can Baikal seals dive? How fast are hippos? How long can freshwater pearl mussels live? And how do water fleas reproduce?

“We really hope that these fact cards will raise the fascination of people about freshwater life,” says project curator Prof. Sonja Jähnig from IGB. “We are very happy about the nice visualisations and illustrations done by Studio Adén. The cards not only show interesting facts on freshwater species and the research conducted at IGB, but they can be used as postcards or decorations.”

“Freshwater biodiversity is underrepresented in the information presented to the general public, often being out of sight, out of mind. We would like to use the Freshwater Fact Cards to highlight amazing freshwater life and promote public awareness and conservation actions for freshwater biodiversity,” says Dr. He.

“We will distribute the cards widely at outreach events, where visitors can take them as small souvenirs,” says Prof. Jähnig. “The fact cards also support the Alliance for Freshwater Life in their ambition to raise the profile of freshwater biodiversity and make people better understand, value, and safeguard freshwater biodiversity.”

The Freshwater Fact Cards project is still growing. “If you have an idea for which species we should add, or if there is an idea for a new set of species from a certain region, or including other artists, please reach out to us,” says Prof. Jähnig.

MERLIN restoration case studies: large transboundary rivers

August 18, 2022
The five large transboundary river sites in the MERLIN project: (4) Room for the Rhine branches, Netherlands; (7) Upper-Mid-Danube floodplain, Austria and Hungary; (8) Lower Danube floodplain, Romania; (9) Tisza River, Hungary; (10) Germany’s Blue Belt.

The MERLIN project focuses on 17 freshwater restoration case studies located across Europe.

These diverse sites and projects – including large rivers, small streams, peatlands and wetlands – offer researchers the opportunity to learn about best-practice approaches for restoration in contemporary landscapes. The project will explore how the impact of these projects contributes to the targets of the EU Green Deal.

Moreover, MERLIN is investing more than €10 million in these projects to help upscale their management through the use of nature-based solutions. It is intended that the progress made in bringing freshwaters back to life at these sites will help strengthen arguments for mainstreaming freshwater restoration across the continent.

This is the third of three articles introducing the 17 restoration case studies. This week, we focus on the five large transboundary rivers.

Room for the Rhine Branches, Netherlands

Restoration of a resilient large river system for biodiversity, flood protection and navigation

Ongoing restoration work will be carried out across a 300km network of River Rhine branches throughout the Netherlands. These stretches of river – from the German border to the North Sea – have been heavily modified for centuries, with widespread weirs, embankments and groynes alongside intensive agriculture, mining and urban development.

This restoration of the Rhine branches follows decades of work through the Room for the River programme, which finished in 2018. Whilst significant progress has been made, climate change and channel erosion pose new challenges for restoration, which will be managed in the future through the Integrated River Basin Management programme.

Restoration measures, tailored to local conditions, include: floodplain restoration (e.g. through the removal of artificial channels and dikes); river channel restoration (e.g. the removal of polluted sediments); and connectivity restoration (e.g. the removal of barriers to the movement of water, sediment and fish). The overall aim is to create a more resilient large river system which balances conservation, flood protection, freshwater supply, navigation and recreation needs.

“A lot has been already been achieved by the Room for the River programme, but there are new challenges due to climate change, resulting in more extreme discharge patterns, and incised river beds requiring sediment management,” says Tom Buijse from restoration managers DELTARES. “Its successor is IRM for which the visionary plan should be ready by 2023. This will result in a follow-up programme for the coming decades.”

Upper-Mid-Danube floodplain, Austria and Hungary

Reconnecting floodplains and tributaries to foster multifunctional landscapes

Two stretches of the Mid-Danube River in Austria and Hungary are being restored through a range of measures across its floodplains and tributaries. Whilst the sites are geographically independent, the upscaling of their restoration will be developed together.

In Austria, a stretch of the Danube in the Donau-Auen National Park will be managed towards more natural conditions by reconnecting floodplains to the main river, restoring riparian areas and removing artificial bank structures. It is intended that this range of adaptive restoration measures will help address multiple pressures such as riverbed deepening, the impacts of navigation, flood protection and land-use alterations.

In Hungary, a side branch of the Danube has been reconnected to the main river around the 4km-long Liberty Island. A key goal for this initiative has been to create a long-term, sustainable conservation model for white willow alluvial forests around the river. Restoration work has cleared invasive and non-native tree species around riparian areas, restoring water flows in the river side arm to allow the forest to flourish, even in times of drought.

“This case study represents the systematic process-orientated restoration of a whole large river stretch through adaptive management processes, to address multiple pressures,” say restoration managers from viadonau. “These are multifunctional floodplains, where restoration design should address the maintenance of a variety of ecosystem services and trade-offs including fishing, shipping, flood protection, forestry, agriculture and recreation,” add project partners from BOKU, Vienna.

Lower Danube floodplain, Romania

Reconnecting floodplains to boost biodiversity and buffer floods

Floodplain restoration is being upscaled at a series of sites along the Lower Danube River in Romania. As with much of the basin, the Lower Danube is highly regulated and altered by human construction, and as a result its huge former floodplain is largely disconnected from the main river. Intensive land use around the river has caused further habitat degradation, water and soil pollution, and water supply issues.

Restoration work seeks to reconnect the Lower Danube River with its floodplains as a means of boosting ecosystem health and mitigating flood risks. It is intended that more natural hydrological cycles will be created across wide areas of floodplain, wetland and polder, fostering a biodiverse mosaic of landscapes linked to the river. It is hoped that restoration work will, in turn, encourage sustainable grazing, fishery and aquaculture activities, alongside increased recreational and tourism use.

“The entire Danube river is regulated and long dike system protects the largest former floodplain area in the continent,” say restoration managers from WWF Romania. “The implemented measures use nature-based solutions to reconnect a part of the former floodplain with the Danube River.”

Tisza River, Hungary

Rewetting floodplains for sustainable farming practices

Floodplains on the Tisza River – a major tributary of the Danube – will be reconnected to the river and transitioned to sustainable farming systems. Like much of the Danube basin, the Tisza has been heavily modified by humans, and many of its former floodplains are dominated by intensive arable farming, which has dried out these formerly-wet landscapes.

Two floodplains in the middle Tisza River will be ‘rewetted’ through a series of floodways and flood risk reduction reservoirs. Initially implemented over 1,800 ha of floodplains, this work will increase water retention in the landscape, and create the conditions for sustainable floodplain farming practices.

It is intended that floodplain restoration will not only increase biodiversity and buffer flood waters, but also help foster economically-viable land-use systems around the Tisza. It is hoped that this work could be upscaled to over 150,000 ha of former floodplain landscapes along the Tisza basin.

“This case study presents real integrated solutions for flood risk management, water scarcity in agriculture, biodiversity loss, and climate adaptation,” say restoration managers from WWF Hungary. “It offers new economic and social opportunities for local communities, and for the cooperation of stakeholders.”

Germany’s Blue Belt

Renaturalising a major network of German rivers and floodplains

This ambitious national project seeks to restore around 4350km of rivers and 240,000 ha of their floodplains across Germany. The Blue Belt initiative began in 2019, and aims to renaturalise a huge network of federally-managed waterways, whilst at the same time maintaining their commercial navigability for boat traffic.

Most of the Blue Belt network – which includes major rivers such as the Rhine, Elbe and Weser – is heavily modified, with altered water flows, channel structure and degraded water quality. Floodplains across the network are often subject to intensive urban and industrial land use.

It is intended that renaturalisation of the banks and floodplains of this national river network will create significant new biodiversity habitat and offer new opportunities for tourism and recreation. Restoration work in the Blue Belt initiative seeks to foster a major new biotope network along Germany’s waterways.

“This project aims to ecologically restore functional river landscapes throughout Germany, but at the same time not to set aside commercial navigability,” say restoration managers from the Federal Institute of Hydrology, Koblenz. “Renaturalised federal waterways and their floodplains will form an important part of a biotope network and help to preserve water and floodplain species and their habitats. As a result of this a significant number of ecosystem services are generated, sustained or even enhanced.”

MERLIN restoration case studies: small streams and basins

August 4, 2022
The six small streams and basin sites in the MERLIN project: (2) Basque streams; (11) Emscher catchment; (13) Sorraia catchment; (15) Tzipori catchment; (16) Scheldt catchment; (17) Forth catchment.

The MERLIN project focuses on 17 freshwater restoration case studies located across Europe.

These diverse sites and projects – including large rivers, small streams, peatlands and wetlands – offer researchers the opportunity to explore best-practice approaches for restoration in contemporary landscapes. The project will document how the impact of these projects contributes to the targets of the EU Green Deal.

Moreover, MERLIN is investing more than €10 million in these restoration projects to help upscale their management through the use of nature-based solutions. It is intended that the progress made in bringing freshwaters back to life at these sites will help strengthen arguments for mainstreaming freshwater restoration across the continent.

This is the second of three articles introducing the 17 restoration case studies. This week, we focus on the six small streams and basin sites.

Basque streams, Spain

Reconnecting a heavily altered river through barrier removal.

A series of dams on the 60km-long Deba River in Spain will be removed to allow water, fish and sediment to move freely along its course. The local region of Gipuzkoa has a long history of industrial and urban development, and as a result the Deba’s channel is heavily altered. Many of the built obstacles along the Deba are now either obsolete or disused, yet they continue to block the free movement of water and fish.

Restoration work aims to reconnect the Deba River by removing ten dams along its course. It is intended that this work will restore more natural flow conditions in the river basin, whilst also supporting populations of migratory fish such as trout and eels, which migrate upstream to spawning grounds. It is also hoped that dam removal along the Deba will help restore habitat for wildlife.

“A key objective is to promote environmental education and nature-based solutions as restoration policies,” say restoration scientists from the University of the Basque Country. “Stakeholder interaction is being promoted, connecting local communities, institutions and governments.”

Emscher catchment, Germany

Restoring riverbank habitats for biodiversity and recreation.

The Emscher River and its tributaries in Northern Germany have been heavily altered over many years. Urban and industrial development in the Emscher catchment has left much of the river flowing through concrete channels fragmented by weirs, culverts and artificial pumping stations. Cut off from its natural floodplains, the Emscher has been heavily polluted for decades as a result of sewage overflows and industrial run-off.

The MERLIN project will help restore meadow grasslands along riverbanks throughout the Emscher catchment to provide new habitat and recreation areas. These activities will help boost urban biodiversity in the catchment, and will complement wider river restoration measures being undertaken in the region. The MERLIN project will also help foster more participatory water management – for example through citizen science initiatives – and explore synergies between water management and environmental restoration.

“The Emscher restoration is, among other drivers, triggering the structural change in the region with the aim of ecological, social and economic sustainability,” say restoration managers from Emschergenossenschaft. “Nature-based solutions are being implemented in the urban areas to enhance climate regulation and adaptation, improving urban climate and the attractiveness of the cities, and thus, enhancing quality of life.”

Sorraia catchment, Portugal

Reconnection of floodplains and water flows through ‘blue-green’ restoration.

Rivers and floodplains across the Sorraia catchment in Southern Portugal will be restored using measures which improve water quality, boost biodiversity and encourage natural water flows. The Sorraia River and its tributaries are vulnerable to drought, as a result of a Mediterranean climate compounded by irrigation, flow regulation and damming. There are many permanent barriers such as weirs throughout the basin, which provide obstacles to fish migration. In the lower basin, much of the river system has been deepened and connected to irrigation channels. Agricultural activity also brings water quality issues due to nutrient and pesticide pollution.

Restoration in the Sorraia basin seeks to improve ‘blue-green’ connectivity between the river and its floodplains. Strategies include restoring riparian vegetation along river banks and the removal of exotic invasive plants such as water hyacinth and Brazilian milfoil. Other innovative nature-based solutions to be applied in the catchment include the creation of farm ponds, forest islands and ‘pollinator hotels’ to help boost floodplain biodiversity. It is intended that this ‘blue-green’ landscape restoration will also help reduce nutrient and sediment runoff and reintroduce natural water flow dynamics. Fish passes will also be constructed at weirs and river crossings to reconnect migration corridors.

“The case study has the ambition to quantify the importance of greening in the landscape, especially in agricultural landscapes,” say restoration managers from the University of Lisbon. “Both the National Environmental Authority APA and the National Agriculture Authority are part of the Advisory Committee of the Project, and The Farmers Association is a partner. The results are expected to have impacts that could feedback at the international policy level.”

Tzipori catchment, Israel

Floodplain restoration and sustainable agriculture across an entire river basin.

The Tzipori River in Israel is fed by natural springs in the Nazareth Hills, and flows 32km through an intensively cultivated catchment to the Mediterranean Sea. The river is subject to a number of ecological stressors including water abstraction for agriculture, channel modification for flood protection, effluent and sewage pollution, and heavily agricultural land-use.

Restoration of the Tzipori catchment – which covers around 300km2 – centres on floodplain restoration, the creation of natural flood retention basins, and the transition to sustainable agricultural practices. It is intended that restored wetlands, floodplains and riparian vegetation will help naturally reduce flood risks, boost biodiversity, improve water quality and provide new opportunities for ecotourism.

“The restoration plan for the Tzipori takes a broad and in-depth ecological and hydrological perspective, accounting for the interfaces of the river with agriculture, urban spaces, and the open, natural landscapes along its entire length,” say restoration managers from Tel Aviv University. “The implementation of this plan, leading to rehabilitation of the entire river through a holistic river-basin approach, is considered a breakthrough in the field of river rehabilitation in Israel.”

Scheldt catchment, Belgium

Stream restoration for biodiversity habitat and flood protection.

An area of the upper Scheldt River basin around Zwalm in Belgium will be restored through a range of measures aimed at improving biodiversity habitat and water quality and reconnecting fish migration routes. The 355km long Scheldt River flows through France, Belgium and The Netherlands to the North Sea. Its upper reaches consist largely of small brooks, which are heavily impacted by untreated urban wastewater and agricultural pollution.

Restoration work through MERLIN seeks to restore riparian and fish spawning habitat along the upper catchment. Barriers to fish migration will be removed, and fish passes equipped with new online monitoring technologies will be installed to improve the connectivity of the catchment. Advanced new wastewater treatment plan and sewerage systems will be installed to help reduce the environmental impacts of pollution on the upper catchment streams. Water buffer basins along catchment floodplains will help reduce flood risks by slowing the flow of heavily rainfall.

“This project shows that ecological, economic and social aspects of restoration can be optimised in a smart manner, even over large spatial areas in densely populated areas with very high industrial and agricultural activities,” say restoration managers from Ghent University.

Forth catchment, Scotland

River restoration in a post-industrial landscape for flood risk, biodiversity and socio-economic benefits.

Restoration work across the Forth catchment in Central Scotland includes both peatland and stream environments. Stream restoration in the catchment will include upscaling work being undertaken on the Allan Water, a tributary of the Forth. Allan Water (like other rivers within the Forth basin) is liable to cause flooding in downstream urban areas as a result of physical modifications to the river and its disconnection with floodplains.

Restoration work through MERLIN seeks to restore connections between the rivers and their floodplains on the Allan, Forth and Teith, to contribute to natural flood management and the restoration of valuable wetland habitats. Measures include placing large woody debris in the river channel and removing sections of engineered bank protection. Rivers will be reconnected to their floodplains through the removal of embankments and the restoration of stream channels, together with riparian tree planting. Through these works, restoration managers hope to create a more natural meandering river course surrounded by biodiversity-rich habitats. It is also intended that this work will help buffer flood risks, store carbon, and help boost local communities.

Restoration of these rivers in MERLIN is undertaken in partnership with The Allan Water Project Steering Group and others, which engages with landowners to support sustainable land management practices.

“The Forth Valley provides a rich and diverse landscape with a wide range of ecosystem services that have been impacted by centuries of mining, industry and urban expansion that along with poor management has compromised the natural assets of soil, water and air and includes areas of significant economic deprivation,” say restoration managers from the University of Stirling. “Despite this, the diverse landscape, interconnected with rivers, lakes, estuary and coastal environments presents many of the solutions required to support a smooth inclusive and just transition to a net zero economy, whilst mitigating against the extremes of climate change.”

Creativity and conservation: a Red List of creatures of Scandinavian folklore

July 20, 2022

Linnéa Jägrud is a limnologist based in Gothenburg, Sweden. Her work in MERLIN addresses peatland restoration in Sweden. Over the course of a year, Linnéa travelled with photographer Tore Hagman across Sweden to trace the landscapes of Nordic folkloric creatures called ‘vaesen’. As Linnéa explores in this guest article, their search for vaesen reveals the deeply-rooted cultural and historical connections to nature in Swedish landscapes. These connections can, in turn, deepen our modern-day understandings of ecological conservation and restoration.


For thousands of years, we humans have changed our landscapes. The last century has been extra-hard for nature. Our formerly-rich environment has lost so much. Species are pushed aside towards Red Lists of Threatened Species. We must take better care of our Earth, so that all Earthlings can continue to exist.

The Scandinavian folklore creatures known as ‘vaesen’ are strongly connected to the landscape. For thousands of years, humans have passed on ancient stories about our Nordic vaesen. Men and women have seen them in the hide of the forest, or in the dim of the barn. A hint can be seen in the salt of the wave and the vortex of the stream. But what if the vaesen are more than just stories?

Or, even worse. What if we were not alone, but we are now? Could it be, that the landscape has changed so drastically that we have lost more than birds, meadows, bats and lichen? Could the vaesen also be on the Red List? And if so, what if we have also lost a piece of ourselves?

Living folklore in Swedish landscapes

Like a tree, this project was once a seedling in the head of Tore and I. Our idea rapidly grew into something more: a will to tell the story of the folkloric vaesen. And by tracing the landscapes of the vaesen across Sweden through photography, we wanted to offer a new perspective on modern-day conservation and restoration imperatives to “save and restore.”

With a common love for nature, with joy and creativity, sweat, laughter and some drops of blood, Tore and I took twenty-one photographs depicting the Nordic vaesen in the environments which birthed their folklore. The vaesen is strongly connected to the landscape. In the dark of the Swedish winter, it was easy to mistake a stump for a troll, or a rat for a tomte, a sort of gnome. Or maybe, these sightings were not mistakes?

Before electricity came, the vaesen was often seen and there are thousands stories about child being taken by trolls, women being drowned in the river, or men being seduced by the beautiful but dangerous “Lady of the Forest”. But there were equally as many stories about lost people who found their way thanks to the vaesen, or fishermen who got good catches after offering up a coin.

Creativity and conservation: photographing the vaesen

It is commonly known that the nature is, and always has been, a great inspiration for many artists and authors around the world. Some of the vaesen we photographed are still commonly known in Scandinavia, but not all of them. Through our work, we saw a strong correlation between the fragmentation and domestication of the landscape and the loss of vaesen folklore. The conservation of landscapes is not only about biodiversity, but folklore, too.

The further north in Sweden one goes, almost to Norway, the more time people spend in nature in their daily lives. It’s in these places that the vaesen folklore stays alive. Even further out, in Iceland, road construction is forced to take diversions around sites where folklore says that Icelandic elves dwell. In central Europe, with concrete, cities, intensive agriculture and irrigation systems, the beauty of the nature is so often lost, biodiversity is degraded and the folklore which springs from the landscape disappears. As a consequence, when we lose the stories which tie us to a landscape, we may lose the feelings which prompt us to conserve and restore its nature. And if we lose the love for the nature, we no longer consider it so important to keep.

I chose the locations for the photo shoots based on what would have been a suitable habitat for the vaesen. It required a lot of background research with folklore experts and Facebook groups. For example, for one shoot, I needed to find a horse that can actually stand still without someone holding it. And the horse needed to be in a lake with lilypads in the hair! Not all horses can do that, but eventually, after searching several social media groups, I found a very calm and nice horse named Brolle, who could do the job.

For the Kraken picture, we created a papier-mâché tentacle that is over three metres long, and had to transport it and the small wooden boat out in the sea. Papier-mâché, ocean, leaking wooden boat and rain is a very bad combination. The weather conditions were extremely important and at the very last second, the wind calmed down and we could take the shot. The Lady of the Mine picture required a visit to the mine of Taberg, south of Jönköping. It is a very old mine, but it closes during winter to protect the bats. Hence we had to hurry up and make our way between flying bats in the complete dark of the mountain, before it closed for half a year.

Using leftovers from a Viking house building, my husband Johannes and I built the exhibition frames for the photographs. We created “species-specific factsheets”, which included the last observation of the vaesen, its Red List category, biotope, threats, and measures to save it, which were printed directly on a metal plate. The sounds which accompanied the photographic exhibition were also very important. I carefully picked the appropriate birdsong for each environment, in order to evoke the sounds that surrounds the photos. Currently the exhibition is shown at Rydals Museum, on the west coast of Sweden. In the autumn, the exhibition is ready to tour and be shown in other places.

Freshwater folklore: a Red List of the vaesen

An important thing about these vaesen is their name. Many of the Scandinavian vaesen are named “rå” (raa). A rå is a vaesen that protects and take care of a certain place. Hence, the Skogsrå, the lady of the forest, is not only a good-looking women in the forest. She is the forest. She is a vital part of what we today would call the ecosystem. She takes care of the animals in the forest and guards the trees. Maybe that is why she used to seduce the timber men? Maybe she did not want them to cut the trees? The Havsrå, the mermaid, is another rå, who takes care about the coastal areas and guards it. She decides if the fishermen shall get fish, or not. There is also a rå in the mine, and she seems to prefer the bats and keep them safe during winter. Numerous stories tell that you must always be polite towards the rå. Greet them by name and give them some small gift, and you shall be greatly re-gifted. The Gruvrå (Lady of the Mine) could tell you if the mountain was safe to enter, and the mermaid could tell you when there was a storm coming in.

Our folkloric Red List is based upon how fragmented the vaesen’s environment is today. Trolls for example, need very old forests. Since almost all of the old forests have been cut down, the trolls are left to survive only in nature reserves and national parks. The nix, or Näcken in Swedish, is a water man that live in the strong wild stream. He is traditionally found to be playing the fiddle, and sometimes luring innocent humans into the stream. What will happen when there is a hydropower station being built? The stream is lost and the music of the river can no longer be heard.

On the mire, we have at least two kinds of vaesen. The old women of the mire, or the mosekone, is a Danish vaesen. She is said to have a magic cauldron, and when she brews, the fog will rise and spread over the landscape. It is also said that it is the fog that keeps the bog alive. When the peatlands were drained, the water disappeared and the fog was gone. Since the mosekonen could no longer do her magic brewing, the frogs and dragonflies died. The same destiny has hit the fairies. They are known for dancing in the fog. After draining mires, the mist disappeared, and the fairies are no longer seen dancing.

Storying freshwater restoration

The work with the Nordic red listed vaesen has made me think more about the story behind restoration. In the EU MERLIN project, we often talk about engaging people in plans for freshwater restoration. The story behind the Red Listed vaesen is actually saying the same thing, but with another narrative. We need to restore these vitally-important freshwater environments, not only for their ecology, but for their cultural importance, too.

We know that we have lost biotopes, habitats and species. This is a fact, and should be enough for anyone to immediately act strongly for conservation and restoration. But what if we have lost more than species? What if we have lost a deeper connection to nature through the disappearance of the vaesen in everyday life? Stories of the vaesen return magic to the landscape. What needs to be done is to bring people out into nature. Let them have some magic. Let the nature be living on more than one level. Imagine the forgotten creatures that once existed in many places. Find the stories before they are completely lost.

Water Always Wins: Thriving in an Age of Drought and Deluge

July 6, 2022

Water is central to so many contemporary environmental issues. Climate change, biodiversity loss, flooding, the list goes on: water percolates through the key global challenges we face in shaping sustainable futures on Earth.

But after decades of corralling water away from floodplains and wetlands into channels, dams and sewers, a new generation of ‘water detectives’ suggest that humanity’s desire to control water should be rethought. These water detectives – a loose global network of restoration ecologists, hydrogeologists, biologists, anthropologists, urban planners and engineers – are the focus of Erica Gies’ new book Water Always Wins: Thriving in an Age of Drought and Deluge.

Gies highlights that many of the water detectives she studies are asking the same fundamental question at their sites: what does water want? That is, what natural patterns, rhythms and dynamics did water cycles have in particular locations, before their landscapes were radically altered by human development? And could giving up attempts to control water actually help mitigate contemporary environmental issues such as intensifying floods and droughts?

Through following projects at sites across the world, Gies suggests that vital new approaches to water management which focus on repairing – or mimicking – natural hydrological systems are emerging globally. Such projects include dam removal, floodplain reconnection and river re-meandering. And, as projects – such as MERLIN – focused on such nature-based solutions for restoration are finding, repairing natural water systems can have significant wider ripple effects which address issues such as biodiversity loss and climate crisis.

Gies argues that the infrastructure of many global water systems has removed the ‘slow’ phases of the water cycle. These phases often occur on wetlands, floodplains and peatlands, where water slowly flows, percolates and settles in the landscape. Gies highlights that such slow phases of water are often “where the magic happens” in supporting flourishing ecosystems, naturally filtering water, and buffering flood surges. However, many such environments have been lost to human development over the last century, and are now in pressing need of restoration.

As a result, Gies advocates for a Slow Water approach to contemporary water management. Resonating with the long-established Slow Food movement, she outlines an approach which works with local landscapes, climates and cultures to restore the natural ‘slow’ phases of water to support water supply, flood control, carbon storage and biodiversity habitat.

Support for such approaches requires a shift in how we perceive our water landscapes, Gies suggests. “A big part of shifting to water management that collaborates with nature is giving up the illusion of control,” Gies writes. “Green infrastructure is not static or predictable like concrete: nature is messy. Water rises and falls. Plants sprout, live, and die. Mud is exposed. Although these spaces can be beautiful – perhaps more beautiful than, say, a dam – people might not always like what they see. We will need to learn to accept a dynamic environment.”

Accordingly, Gies aligns the Slow Water approach with Aldo Leopold’s land ethic, which frames humans as part of wider communities of non-human life which carry moral and ethical responsibilities for conservation and care. Such an outlook is currently being extended in the modern ‘rights of rivers’ movement, in which naturally-functioning freshwater systems are given right within legal systems.

Through Water Always Wins, Gies follows a series of ‘water detectives’ as they apply Slow Water approaches across the world. In Seattle, USA, an urban stream named Thornton Creek is broken out of concrete channels into new floodplains, bringing back a whole food web of aquatic life, reducing flooding and restoring salmon spawning grounds. In Devon, UK a trial reintroduction of beavers is found to naturally filter river water, boost biodiversity and buffer flood surges as a result of the animals’ ‘ecosystem engineering’.

In Chennai, India, large areas of periodically-flooded marsh and wetland are restored in collaboration with local communities as a means of reducing droughts and floods and creating biodiversity habitat. And in China, a series of ‘Sponge Cities’ incorporate restored greenspaces and wetlands to help store and slow the flow of heavy rainfall to mitigate flooding and filter pollutants.

These diverse projects provide inspiration for anyone seeking to better understand – and manage – our contemporary relationships with water. Broadly, they all involve a ceding of our human control of water, and an embrace of uncertainty and complexity towards working with nature to achieve conservation and restoration goals. As Gies concludes, through such Slow Water approaches, “In letting go, in providing space, we acknowledge the power of waterlands – to hold water, to hold carbon, to hold life, including us. In giving, we receive.”


Water Always Wins: Thriving in an Age of Drought and Deluge

Major new Nature Restoration Law proposes restoring 20% of European ecosystems by 2030

June 23, 2022

The European Commission published a proposal for a major new European Nature Restoration Law yesterday. The proposal suggests a series of new binding targets to restore 20% of the EU’s land and sea by 2030, alongside deadlines for the restoration of important natural habitats. Further, it suggests that all European ecosystems in need of restoration should be restored by 2050.

The proposed Nature Restoration Law is an indication of the vital contemporary importance of ecological restoration, both in Europe and worldwide. The proposal is intended to build on existing environmental policy such as the EU Green Deal and Biodiversity Strategy for 2030 to ensure that Europe’s ecosystems are restored, resilient and adequately protected.

“The window to adapt to the reality of the climate crisis is rapidly closing,” says Laura Hildt, Policy Officer for Biodiversity at the European Environmental Bureau. “The Nature Restoration Law proposal is a strong tool to bring back and improve ecosystems that can help us to deal with droughts, floods and heatwaves. The overarching obligation to restore 20% of the EU’s land and sea by 2030 can be game-changing – provided all Member States do their fair share and put in place real restoration measures.” 

EU Member States will be required to develop new national restoration plans to achieve these ambitious goals within national environmental and social contexts. Through supporting the restoration of Europe’s ecosystems, the Nature Restoration Law is intended to help boost biodiversity, limit climate change, build up resilience to natural disasters – such as floods – and reduce food security risks. Moreover, environmental restoration can have significant benefits to our health and wellbeing, and help create new sustainable jobs and ecotourism opportunities.

“We’re not just talking about the survival of nature, we’re talking about the survival of humankind,” says Sofie Ruysschaert, Nature Restoration Policy Officer at Birdlife Europe and Central Asia. “From farming to fishing, our ability to continue feeding humanity hangs on repairing the damage done to ecosystems while we still can. Vested interests argue that nature is a threat to our food provision, but the truth is that it is our most important ally. But the devil is in the details – this law can put nature on the path to recovery only if it makes governments take effective measures to recover species and habitats severely impacted by intensive agriculture, forestry and fisheries practices.”

Rivers, floodplains and peatlands are all addressed in the new proposal. It outlines that the objective of restoring 25,000km of free-flowing EU rivers in the Biodiversity Strategy should be supported by the ongoing removal of barriers such as dams and weirs. The proposal suggests that major new inventories of barriers to water movement – both along river channels and out onto floodplains – should be made, and obsolete barriers should be urgently removed. This is intended to result in the restoration of the natural connectivity of rivers and their floodplains.

The Nature Restoration Law proposal also calls for the restoration and rewetting of degraded European peatlands, emphasising the vital role they play in storing carbon and providing biodiversity habitat. It places peatland restoration as a key aspect of agricultural restoration targets in the new policy.

However, WWF researchers point out that whilst it is positive that river and peatland restoration is given direct attention in the proposal, there are still improvements that could be made. They suggest that Member States should be required to restore 15% of the length of European rivers (or 178,000km) as free-flowing, as well as restoring their floodplains. Further, they suggest that the proposal’s targets for peatland restoration need to be strengthened and specified to ensure they function as effective carbon stores.

The Nature Restoration Law proposal will now be considered by the The European Parliament and Council of the EU ahead of its potential adoption. If adopted, the new Law is expected to come into force in 2024.

“The restoration law is a huge opportunity to bring nature back before the climate and biodiversity crises spiral completely out of control,” says Sabien Leemans, Senior Biodiversity Policy Officer at WWF European Policy Office. “Restoration of ecosystems like peatlands, forests and seagrass meadows can help reduce emissions and sequester millions of tonnes of carbon each year. The Commission’s proposal is good, but we need to keep in mind the urgency and make sure the bulk of the restoration action in these ecosystems is not pushed back beyond 2030. This decade must be the turning point to place nature on the path to recovery.”

A step closer to Europe’s first Wild River National Park on the Vjosa River

June 15, 2022

Conservation of the Vjosa River took an important step forward this week as the Albanian government signed a commitment to establish Europe’s first Wild River National Park across its catchment.

The Vjosa is often termed one of ‘Europe’s last wild rivers’, flowing largely-unobstructed by dams and hydropower schemes from the Greek mountains through Albania to the Adriatic Sea.

In recent years, scientists and campaigners have sought to highlight the diverse ecosystems and wildlife supported by the Vjosa and its tributaries. A report released last year documented over 1100 plant and animal species across the catchment, including 13 globally threatened animal and two plant species. The report authors argue that Vjosa is thus a vital ‘near-natural’ river system, which has been largely lost elsewhere in Europe.

However, until now the Vjosa catchment as been afforded scant environmental protections, and has been threatened by a number of proposed hydropower developments and oil prospecting. The new agreement, signed in Tirana on Monday, states that the Albanian government will work with the Save the Blue Heart of Europe NGO group and Patagonia organisation to establish a Vjosa Wild River National Park.

It is intended that protections of the Vjosa River and its free-flowing tributaries will be raised to the IUCN Category II Level National Park. Under this designation, large ‘natural or near-natural areas’ are set aside to protect large-scale ecological processes. In other words, this level of protection would severely limit the potential for future hydropower and dam construction in the Vjosa basin, in order to conserve its biodiversity and ecosystems.

“Albania’s Vjosa is nature’s unrelenting force, the only survivor of the wild rivers of our continent, the last river vein that bears no trace of contamination from the industrial development that has morphed Europe’s rivers into animals tamed for the energy-generation circus,” says Albanian Prime Minister Edi Rama.

“Vjosa will remain the only wild water body that, just like on the day of its creation, will continue to bear witness to the wonder that once were the European riverbeds,” continues Rama. “Under the protective cloak of the National Park, Vjosa will stay intact for Albania, for Europe, for the planet we want for our children’s children.”

The agreement follows years of campaigning from groups such as Save the Blue Heart of Europe, who term the Vjosa the ‘last wild river in Europe outside of Russia’. The catchment is characterised by a mosaic of habitat types, from fast-flowing gorges to braided floodplains and deltas, many of which have high conservation importance. Moreover, the Vjosa basin is vital in supporting local communities through fishing, farming and – increasingly – eco-tourism.

“Albania’s leaders have shown vision and commitment today, signalling to the world their intention to do something unprecedented in nature protection,” says Patagonia CEO Ryan Gellert. “Through our long-standing partnership with the NGOs behind the Save the Blue Heart of Europe campaign, we have learned first-hand just how exceptional the Vjosa is and are therefore humbled to work alongside the government and groups, devoting our skills and expertise to the establishment of Vjosa Wild River National Park.”  

“While there is much work to do before we can guarantee the future of the Vjosa, this is a major milestone for Albania and for river defenders everywhere,” states Besjana Guri from EcoAlbania. “The ambition of creating Europe’s first Wild River National Park is one step closer to becoming a reality.”

MERLIN restoration case studies: peatlands and wetlands

June 8, 2022
The seven peatland and wetland sites in the MERLIN project: (1) Nørreådalen ved Kvorning, Denmark; (3) Beaver reintroduction, Sweden; (5) Kampinos wetlands, Poland; (6) Karstic peatland, Bosnia and Herzegovina; (12) Lima basin, Portugal; (14) Oulujoki-Iijoki catchments, Finland; (17) Forth catchment, Scotland.

The MERLIN project focuses on 17 freshwater restoration case studies located across Europe.

These diverse sites and projects – including large rivers, small streams, peatlands and wetlands – offer researchers the opportunity to explore best-practice approaches for restoration in contemporary landscapes. The project will document how the impact of these projects contributes to the targets of the EU Green Deal.

Moreover, MERLIN is investing more than €10 million in these restoration projects to help upscale their management through the use of nature-based solutions. It is intended that the progress made in bringing freshwaters back to life at these sites will help strengthen arguments for mainstreaming freshwater restoration across the continent.

This is the first of three articles introducing the 17 restoration case studies. This week, we focus on the seven peatland and wetland sites.

Rewetting peatlands for carbon storage, water quality and biodiversity

A 430 ha area of lowland arable fields in Northern Denmark will be ‘rewetted’ through the restoration of natural hydrological processes. Measures to restore the site’s peatlands include closing agricultural drainage ditches and re-meandering streams.

The plan is for the water level of the site to rise, which will reduce the loss of organic carbon stored over millennia and reinstate the conditions for its natural formation. In turn, it is intended that peatland restoration will reduce carbon dioxide and nitrous oxide emissions from the soil, and improve carbon sequestration from the atmosphere. This will improve the site’s capacity to act as a greenhouse gas sink.

State-of-the-art filter technologies will also be used to reduce phosphorous pollution into surrounding streams. Cleaner water and better habitat quality resulting from restoration are intended to boost biodiversity at the site.

“Rewetting in combination with other restoration measures is proposed as a valid strategy to restore the unique biodiversity of peatlands and the recreation of the carbon and nutrient sink function,” say restoration managers from the Danish Nature Agency.

Beaver reintroduction, Sweden

Natural ecosystem engineering to boost biodiversity, reduce flooding and mitigate drought

Beavers are recolonising forest landscapes in river catchments across Sweden following decades of decline. Beavers are natural parts of these ecosystems, but their numbers have been reduced in many areas due to human activities and over-hunting. Reintroductions of beavers from Norway took place in Sweden in the 1920s and 30s, and their populations have gradually spread since.

By building dams, beavers act as ‘ecosystem engineers’ which can benefit the wider landscape. By raising water levels and slowing river flows, their dams can help mitigate drought and reduce flooding. Studies also suggest that their activities can benefit the wider ecosystem by creating nursery areas for spawning fish and new habitats for plants and insects.

Beaver reintroduction work in MERLIN builds on existing projects across Sweden. These projects frame the animals as active participants in the ecological restoration of river catchments degraded by agriculture and forestry: a truly nature-based solution.

“The restoration performed by beavers could catalyse landscape transformation due to the ecosystem engineering scale of their activities,” say case study managers from Swedish University of Agricultural Sciences.

Kampinos wetlands, Poland

Restoring wetlands for biodiversity, flood buffering and carbon storage

Two hundred and fifty years of drainage for agriculture have caused the Kampinos wetlands in central Poland to shrink and dry out, leading to the loss of important biodiversity. Restoration at the site seeks to ‘rewet’ over 6000 ha of the wetlands by constructing small dams and dykes which slow the flow of water from the site and raise the groundwater to pre-drainage levels.

The Kampinos wetlands are a unique habitat. Located close to the city of Warsaw, they are protected within a national park and UNESCO Biosphere Reserve due to their habitats for rare plants, birds, mammals, fish, amphibians and insects. Restoration work at the site is intended both to boost biodiversity and improve wetland capacity to buffer floodwaters and store carbon.

“This case study is a diverse, large-scale wetland protection effort which is implemented in the neighbourhood of highly urbanised area and area of large human pressure,” say site managers from the Kampinoski Park Narodowy. “Restoration is expected to enrich the biodiversity of meadows, ditches, rivers and ponds.”

Karstic peatland, Bosnia and Herzegovina

Restoring sustainable water systems in a unique peatland landscape

The karstic peatlands in Bosnia and Herzegovina are a hotspot for biodiversity and a vital landscape for carbon sequestration. Their unique formation of peatland on karstic limestone bedrock is extremely rare, and is increasingly threatened by water demands for irrigation and hydropower. This, coupled with land reclamation for agriculture, significantly threatens the karstic peatland ecosystems of the region.

The complex water flows – through underground rivers, sinkholes and springs – across karstic peatlands makes restoration management challenging. Their restoration requires close collaboration with agriculture and hydropower industries to shift their practices towards sustainable water usage, which will allow more natural water systems to return to the landscape.

“The Dinaric karst fields are biodiversity hotspots – especially for endemic species – as well as the most prominent natural carbon sequestration ecosystems in Europe,” say environmental managers from WWF Adria. “The Dinaric karst fields have played a crucial role for climate regulation and mitigation of climate change. Water allocations and land reclamation have brought the karst field ecosystems to the brink of disappearance.”

Restoring Iberian river corridor wetlands and forests

Restoration of wetland and floodplain forest is planned along the River Lima in north-west Portugal. Floodplains along the Lima valley have been drained, channelised and altered for decades to allow urban and agricultural development. In addition, the river is regulated by two large hydropower dams.

Restoration of the Lima floodplains seeks to re-establish wooded wetland ecosystems, as part of a wider LIFE Fluvial project to improve ‘river corridor’ habitats across the north-west Iberian Peninsula. This work highlights the value of river corridors as unique connections between freshwater and terrestrial habitats. Restoration measures in the catchment will include livestock grazing management, invasive species control (particularly of Eucalyptus plantations and Acacia species) and native tree planting. Fish passes will be installed on the hydropower dams.

“The floodplain forest restoration intends to develop and demonstrate an ecological restoration approach for fluvial floodplains transferable to lowlands across the biogeographic region of the north-west Iberian Peninsula,” say project managers from the University of Lisbon.

Participatory watershed visions for restoring abandoned peatlands

The peatlands in the Oulujoki-Iijoki river basin region in Northern Finland have been altered and drained for forestry, agriculture and peat extraction for decades. This has caused the loss of peatland ecosystems, alterations to stream habitats, and deterioration in water quality due to nutrient, carbon and dissolved metal pollution.

Environmental management across the basin seeks to find sustainable land uses for extracted peatlands by restoring their ecosystem functions through ‘rewetting’. The plan is that peatland restoration will boost biodiversity and help naturally purify water in the basin, improving water quality. It is also intended that restoration will help buffer floodwaters, and improve carbon capture and storage in the basin.

Restoration in the Oulujoki-Iijoki basin is being guided by ‘watershed visions’ which involve local communities, experts, NGOs and government in participatory management, and offer funding for local restoration projects.

“These watershed vision projects provide innovative applications for restoration projects and governance at different scales,” say restoration managers from the Finnish Environment Institute, SYKE. “The idea behind these projects is that there is an advisory board, consisting of local people, NGOs and municipalities, which sets up collective targets for the future and determines ways how to reach them.”

Wetland and peatland restoration for ecological, economic and social benefits

Peatland restoration plays a key role in Scotland’s ‘green recovery’. Restoration can help deliver the transition to net-zero by supporting the rural economy through the creation and development of land-based jobs and skills across Scotland.

The restoration effort in the River Forth catchment in eastern Scotland aims to restore several peat bogs and their carbon stores, helping mitigate climate change, reduce carbon emissions and tackle habitat loss. The plan for this case study is to remove conifer plantations, block drainage ditches and rewet degraded peat bogs for improvement of carbon sequestration, water retention capacity and biodiversity.

“This project will also provide us with important lessons to rapidly upscale the most valuable solutions in time to meet our net zero and biodiversity targets,” says the NatureScot lead for the Forth catchment.

RUN BLUE: Mina Guli runs 200 marathons in a a year to raise awareness of the world’s water crisis

June 1, 2022

Mina Guli is the founder and CEO of Thirst Foundation, a non-profit organisation which seeks to address the world’s water crisis.

Mina is running 200 marathons over the course of a year in some of the most water-stressed places in the world. Her final marathon will take place on 23rd March 2023 in New York City to coincide with World Water Day, and the United Nations 2023 Water Conference.

We caught up with Mina to find out more about her work, and her RUN BLUE marathon campaign.


The Freshwater Blog: Tell us about RUN BLUE: why is it important to talk about water right now, and what do you hope to achieve with the campaign?

Mina Guli: The RUN BLUE campaign empowers companies and inspires people around the world to join together to raise awareness, create urgency and drive action on water.

It is important to talk about water right now because water-related challenges are worsening and becoming more urgent. An estimated 2.3 billion people already live with water scarcity. In just 3 years, 40% of the world’s population is projected to live in water-stressed areas. This means more floods and droughts; more biodiversity loss and disease; more hunger and more poverty. Overall, more suffering. 

Globally we need to close the gap on the targets set out in the United Nations Sustainable Development Goal 6 – clean water and sanitation for all. Unfortunately we are way off track to achieve these targets by 2030. With the first United Nations water conference on water in almost 50 years coming up in March 2023, now is the time to ensure urgent action on water happens.

It’s action from companies. Companies use nearly 90% of the world’s fresh water, either directly or indirectly. It’s action from me. I am running 200 marathons to show the urgency of what we are all facing and why we have to act.  Ultimately, it’s action from all of us. We can all become water aware, use water wisely and demand action from the brands we buy from and the government.

What is the Six for 6 framework? How can it help encourage sustainable water management?

The Six for 6 is a best practice framework developed by Thirst Foundation in conjunction with senior global water leaders from business, the NGO sector, government and civil society.

The framework helps companies and business leaders in six ways. First, to set and achieve water quantity targets – essentially, using less water to deliver the same outcome. Second, to set and achieve water quality targets – ensuring water used leaves a company or supply chain as clean as it arrived. Third, to ensure the delivery of clean water, sanitation and hygiene (also known as WASH) for employees and their families in their companies and across their global supply chains.

Fourth, to standardise water reporting and publicise place-specific data on progress to provide greater transparency. Fifth, to value water by understanding water risk and water dependency as part of strategic decision-making. Finally, to take collective action by working with others and implementing supporting policies to solve shared water challenges. Companies who join the RUN BLUE movement and commit to using the framework will also be teamed up with NGOs within the Thirst Foundation network.

Why did you choose to run 200 marathons in one year for RUN BLUE?

I am running 200 marathons in some of the most extreme, water affected places on the planet, to show the urgency of what we are all facing and why we have to act now.

Marathon #1 was on World Water Day 2022 in Uluru in central Australia. Marathon #200 will be on World Water Day 2023 in New York City, USA which is at the same time the United Nations 2023 Water Conference will be taking place. 

By aligning the RUN BLUE campaign with the United Nations 2023 Water Conference, it is hoped we can drive urgency and action – particularly among companies. Companies currently account for nearly 90% of the world’s fresh water use so companies which means, companies can become the biggest problem solvers for water.

How did you choose the locations of the marathons, and how does running through them influence your experience of water issues in different landscapes?

As part of the RUN BLUE campaign, I will travel from Australia to Central Asia, Africa, the Middle East, Europe, India, Latin America, South East Asia, Mexico and America.

Primarily I am visiting places facing water problems so I can hear from locals how the global water crisis is affecting them locally and to share their stories. The stories of women and children in places like India and Bangladesh who have to walk in extreme conditions, and often fearing for their own safety, just to fetch water – and kids in places like South Africa who have to stay home from school, waiting for water to be delivered by trucks.

In addition to visiting negatively affected places, I am also traveling to places where there have been positive water advancements. For example, I recently visited a rural cotton region in Australia called Narrabri and was amazed to learn the Australian cotton industry has improved its water use efficiency by 48% over the past 30 years.  

I will also visit key business districts to speak about the global water crisis publicly and with industry and business bodies, NGOs and government officials. I am looking forward to the chance to give a keynote presentation at Dushanbe in Tajikistan (June 2022), COP27 in Egypt (November 2022) and the United Nations 2023 Water Conference (March 2023).
