Save the Date for RRR2025

Wet landscape. Save the date for RRR2025.

On Global Peatlands Day

02/06/2024 In celebration of this year’s World Peatlands Day, the Greifswald Mire Centre warmly invites you to save the date for the 4th international RRR conference on the Renewable Resources from Wet and Rewetted Peatlands. Taking place in Greifswald, Germany from September 23rd to 26th, 2025, the conference will unite experts from diverse disciplines to share insights and experiences and address pressing questions within the field of paludiculture.
In 2024, "paludiculture" marked its 25th anniversary since being called into life, with significant advancements made in practical knowledge regarding rewetting, cultivation, processing, marketing, policy development and awareness-building, but large-scale implementation is still low. This conference aims to unite stakeholders involved in the utilisation of rewetted peatlands, welcoming scientists, landowners and users, administrators, manufactors, artists, designers and policymakers. By fostering cross-sector networks, sharing experiences and knowledge, we seek to bridge the gap between science and practice and together discuss and shape the future of paludiculture.
Through a diverse program including lectures, poster presentations, excursions, and a range of interactive events, we endeavour to facilitate meaningful dialogue and collaboration. Stay tuned for further details, including abstract submission and registration information, which will soon be available on our website. We look forward to your participation! For conference updates please visit our website, or follow @greifswaldmoor on the GMC’s social media channels.

Afforesting drained peatlands?

No viable option, new GMC paper shows

13/05/2024 Although the EU Nature Restoration Law was wiped off the EU’s trilogue-agenda in March, scientists took a close look on what was suggested as a restoration measure during the negotiations: active afforestation of degraded peatlands. Their conclusion: evidence for long term overall climate benefits is lacking. Their recommendation: the NRL should foster true natural ecosystems wherever possible, particularly where those are demonstrably carbon capture systems.
For the article “Active afforestation of drained peatlands is not a viable option under the EU Nature Restoration Law” peatland professor Gerald Jurasinski with colleagues of Greifswald Mire Centre and other European peatland scientists assembled facts of several studies. In most cases CO2 release from peat soil degradation will likely exceed carbon sequestration in the forest biomass, as the paper pubished in Ambio Journal of Environment and Society states. It is pointing out the severe challenges to measure greenhouse gas fluxes in peatland forests both with airtight chambers and eddy covariance technique. Another point of critique: the studies quoted in favor of afforestation do not describe the situation after afforestation of agricultural fields or cutover peatlands.

No peatlands in Bellevue's Garden?

Yes - at the Environment Week 2024

13/05/2024 There are no peatlands in the garden of Bellevue Palace? That's right, but there will be during the Environment Week on June 4-5.

We from the Greifswald Mire Center, together with the Agency for Renewable Resources, will be demonstrating how important peatland protection is for climate protection - with cattail in the wall and peat moss on the plate - at the Environment Week of Federal President Frank-Walter Steinmeier and the German Federal Environmental Foundation (DBU).

At our stand no. 35, interested visitors can find out how peat moss is propagated in a bioreactor or what a landscape with paludiculture looks like in a model. As a souvenir, you can take home some cress in a home-made press pot - filled with substrate made from paludiculture biomass, of course!

Registration for the event is open until May 15.

But what is the Environment Week? Not quite for a week, but for two days, Federal President Frank-Walter Steinmeier and the DBU invite environmental and nature conservation organizations and other exhibitors to the park of the official residence to showcase current and imaginative ideas and projects for more environmental, climate and species protection. The show is intended to inspire all participants for a sustainable future. The park will be transformed into a tent city. This year, around 190 exhibitors and more than 70 specialist forums on health, society, the economy, nature conservation, etc. will be taking place.

The Week of the Environment was launched in 2002 by the then Federal President Johannes Rau. Since then, it has been organized together with the Osnabrück-based German Federal Environmental Foundation. This year it is in its seventh edition.

Launch of PaludiAllianz

SOM-Card launch of the Alliance of Pioneers.

Companies for paludiculture

It was end of April, but the beginning for the Alliance of Pioneers: 14 large commercial enterprises from the paper, packaging, construction, insulation and wood-based material industries declared at a kick-off event in Berlin that they would test renewable, regional raw materials from wet peatlands in their production and integrate them wherever possible. According to the joint press release issued by the Michael Otto Environmental Foundation and the Succow Foundation, partners in the Greifswald Mire Centre, which launched the PaludiAllianz in the toMOORow initiative, the aim is to achieve rapidly growing demand for paludiculture in various sectors of the economy. Well-known companies are now among the founding members:

Interest in future paludiculture products in the construction sector has been expressed by prefabricated house manufacturer Bau-Fritz GmbH & Co. KG, the construction group STRABAG SE and OTTO WULFF Bauunternehmung GmbH and Sto SE & Co. KGaA. The companies toom Baumarkt and OBI Group Holding SE & Co. KGaA also consider biomass from paludiculture in the horticulture segment as a supplier of substrates. The retail and service company Otto (GmbH & Co. KG), LEIPA Group GmbH, the WEPA Foundation and, in the area of recyclables management, PreZero Stiftung & Co. KG with OutNature GmbH aim to make paper and packaging more sustainable by adding of paludiculture biomass. Procter & Gamble Service GmbH is involved in the area of consumer goods for household and cosmetics, as is Tengelmann Twenty-One KG with KiK Textilien and Non-Food in the retail sector.
“Development of scalable value chains with paludiculture biomass from rewetted peatlands in Germany in practical cooperation with economic players” (PaludiAllianz) is the detailed title of the project, for which Cem Özdemir, Federal Minister of Agriculture and Nutrition, handed over a funding decision of almost 1.8 million euros over the next three years at Kulturbrauerei in Berlin. As rewetting also offers effective natural climate protection, Federal Environment Minister Steffi Lemke was also a guest speaker at the event.

Methane and rewetting

SOM-Card for film "Why methane emissions do not undermine peatland rewetting (Illustration: Sarah Heuzeroth)

Explained in new film

17/04/2024 This film is troubleshooting this peatland question: What’s the lesser evil - drained peatlands emitting carbon dioxide (CO2) or rewetting causing methane (CH4) emissions? Find answers on:

Do peatlands emit methane? Yes!
Wet peatlands – intact and rewetted - release methane, and the climate-damaging greenhouse gas is also produced when rewetting formerly drained areas. Methane has a much stronger effect on the climate than carbon dioxide , but - remains in the atmosphere for comparably short time.
Then better avoid rewetting to prevent methane emissions? What’s the better choice for climate protection?
Addressing the climate crisis requires reducing atmospheric concentrations of all three greenhouse gases relevant to peatlands (CH4, CO2, nitrous oxide (N2O)). Rewetting effectively reduces long-lived CO2 emissions from peatlands to zero effectively and quickly and is therefore always the right choice for climate protection.
Can we control methane in rewetted peatlands? Yes!
It is possible to minimise methane emissions by various measures as removing biomass ahead of rewetting, avoiding long-term flooding and rewetting gradually
Want to know more about the role of methane, peatlands and rewetting?

MoorMaidens at Mapathon

Open data mining for better peatland maps in Germany and worldwide

A map of all peatlands and wetlands in Europe is to be created as part of the Mapathon at the University of Galway, Ireland, on 6th April. The MoorMaidens, the team of the Greifswald Mire Centre, is determined to engage in quite some sound mapping acitivity the coming Saturday.

The event is intended to draw public attention to the peatlands, but also to the opportunities offered by open data. The wetlands will be considered from the following perspectives: Biodiversity, Climate Protection, Energy, Community & Culture, Environmental Quality - Water, Soil & Air, Land Use & Agriculture, Research & Applied Sciences, Economy.

Here's how it works: Each team selects a specific geographical area that it would like to map, usually a European country. With the help of open data, mire areas and the categories assigned to them are visualised.

The Mapathon will be streamed live on Zoom and YouTube throughout the day, and a technical support team will be available to answer questions via Google Chat. A full list of discovered open data on peatlands will be distributed to all participants after the event.

Interested parties are encouraged to participate online or on site. The main tool used will be QGIS. There will be an introduction and technical support if required.

A mapathon is a coordinated mapping event where the public is invited to make map improvements in their neighbourhood to increase coverage. The knowledge and work of many is brought together to form a whole from which everyone benefits.

The European Peatlands & Policies Open Data Mapathon 2024 starts on 6th April at 11 a.m. CET, and there are also great prizes for the best teams: The winners will receive 1200 EUR.

Biodiversity - how to save it?

SOM-Card: 10 must knows from the world of research (Picture: Leibniz).

10 must knows from the world of research

Good news: There are only six years left to achieve the biodiversity targets, but we can do a lot to effectively conserve biodiversity at local, national and European level, in society and in politics! 64 scientists have compiled their ideas in the new report of the Biodiversity Research Network, coordinated by the Leibniz Association. Peatlands are mentioned right at the top (the Greifswald Mire Centre and the University of Greifswald also contributed to this), as their conservation helps to combat both the climate crisis and species loss.

In fact, only a small part of global biodiversity is understood so far. The report therefore recommends focusing on the functioning of entire ecosystems rather than individual species. Environmental measures can thus become more sustainable. The "10 must-knows from biodiversity research" provide facts for a National Biodiversity Strategy 2030, which is currently being developed. This will enable the German government to implement the 23 global biodiversity targets agreed by the member states of the United Nations at the World Conference on Nature in December 2022.

25 years of paludiculture


07/03/2024 The word paludiculture was born 25 years ago. A "simple" word was needed for an entire concept: rewetting drained moorland to stop the release of greenhouse gases and ... to continue using it in a new, sustainable form of agriculture. It was made up of two Latin words: palus for swamp and cultura for cultivation. A lot has happened since then: Pioneers have tried out paludiculture, research projects have looked at various aspects from sowing to certificates, politicians are looking into it and companies are beginning to discover paludiculture as a market. This development will be celebrated at the anniversary celebration on June 10-11 (lunch to lunch) in Braunschweig. The PaludiZentrale project, jointly organized by the Thünen Institute, the University of Greifswald and the Succow Foundation, invites you to lectures, excursions and intensive networking. The aim is to create a large Paludi network from paludiculture initiatives and projects in Germany to exchange know-how and experience.

Salon: Caspar and peatlands

Landscape painted, but also recognized?

10/02/2024  "Meadows near Greifswald" is one of the most famous works by the painter Caspar David Friedrich. It shows Greifswald and will even be on display in his home town in this year of the romantic painter' 250th anniversary, only ... it does not show meadows. The view up to the town's silhouette  falls on drained peatlands, then as today. In the salon series of the Caspar David Friedrich peatland professor Hans Joosten will talk about this discrepancy, about Adelbert von Chamisso's "Untersuchung eines Torfmoors bei Greifswald", published almost at the same time (1824), and about the relationship between man and nature or landscape. The salon evening on February 22 at 7 p.m. in Ellernholzstr. 1-3 is free of charge, but registration is required.

Accompanying wet peatland use on the way to market

24/01/2024 The PaludiZentrale project bundles four recently launched model and demonstration projects (MuDs) for peatland protection and the utilization of biomass from rewetted areas for more economic paludiculture potential. Jointly managed by Thünen Institute Braunschweig and University of Greifswald, it coordinates and ensures uniform scientific data collection and knowledge exchange. It evaluates results of all aprticipating projects and develops suggestions for political and economic framework conditions as well as recommendations for action for implementation in practice. It also takes care of the transfer of knowledge. The researchers will accompany the new model and demonstration projects in raising the water level at least close to the surface on peatland areas and growing paludicultures (Latin palus: swamp, cultura: agriculture). Another task is to push the utilisation of peatland biomass towards practical use. The projects “Management and biomass utilization of wet fens in Brandenburg (WetNetBB)”, “Living Lab Teufelsmoor – climate and nature conservation-oriented wet management of peatland soils with innovative growth utilization in the Osterholz district (LivingLab Teufelsmoor)” and “Sustainable production and utilization of cattails on fen sites in Lower Saxony (RoNNi)” in Lower Saxony are concentrated on the cultivation of reed and cattail to be used e.g., in building materials or as energy source. The project “Sphagnum paludiculture as a sustainable agricultural use of raised bog soils (MOOSland)” is developing large-scale peat moss cultures for substituting peat.


The rewetting of peatland reduces emissions that are harmful to the climate. In addition, climate-friendly, even climate-positive and locally renewable raw materials can be obtained from these areas for a circular economy as a replacement for previously used petroleum-based materials. The market for biomass from wet peatlands is still small. However, the large-scale rewetting of peatlands can only be successfully implemented with an economic perspective. This perspective is crucial to promote acceptance among both land owners and users and throughout society. That is why the four MuDs and the overarching technical coordination through the PaludiZentrale project are dedicated to building value chains from cultivation to utilization. They are aimed at the building materials, paper and fiber, horticultural substrates and energy production industries. PaludiZentrale ensures exchange and advice on the development of appropriate products, raw material properties, requirements and possible hurdles not only between the MuDs, but also with industry representatives, farmers and other actors. This ensures that scientists can collect and comprehensively evaluate data using a uniform and comparable methodology. This refers to cultivation and utilization, to business and socio-economic analysis. It also concerns the monitoring of long-term economic and ecological impacts, for example how greenhouse gas exchange, soils, hydrology, water quality and biodiversity develop on the rewetted areas. The researchers derive recommendations under which conditions paludicultures and their utilization in regional value chains can be economically worthwhile. This is followed by the transfer of knowledge in politics, practice and society, which is implemented jointly by the Michael Succow Foundation and the University of Greifswald, both partners in the Greifswald Mire Centre. The Federal Ministry of Food and Agriculture (BMEL) is supporting the ten-year project with funds from the Climate Transformation Fund (KTF); the project sponsor is the Agency for Renewable Resources (FNR). In addition, the PaludiZentrale project also aims to network the MuD projects via the so-called “PaludiNetz” with four pilot projects on moorland protection that are already underway and run by the Federal Ministry for the Environment, Nature Conservation, Nuclear Safety and Consumer Protection. (BMUV) is financed by Z-U-G gGmbH as the project sponsor and will also run for ten years.

Come to the construction site

Guided tour through peatland library for WWD

23/01/2024 To mark International Wetlands Day on February 2nd, “peatland pope” Prof. Hans Joosten is taking visitors - no, not into a peatland - but to the construction site, both analogue and online! To a building where inspiration will drip from the walls and tens of thousands of books in all genres and languages will be available on one topic: peatland. Renovation work is currently underway in the former lecture hall of the "Alte Chemie (Old chemistry)" at Greifswald, as this will be the new home of the  Peatland and Nature Conservation International Library PeNCIL. With 50,000 publications, this special collection is an important part of the Greifswald Mire Centre and of international importance.
In 2024, boxes of books shall move into the listed hall and be accessible barrier-free in the high room with two galleries. Statics, financing, pollution issues - there were and still are many challenges to overcome on the way from the vision of a splendid peatland library to its realisation. Hans Joosten will guide visitors through the wing, which was built at the end of the 19th century, and tell them about its history, the complex mercury decontamination and the new peatland contents. If you can't be there on WWD, you can follow a "small library construction site tour" on the Greifswald Mire Centre Facebook and Instagram accounts that day.
On site, the meeting point is in the inner courtyard of Soldmannstrasse 16 (,13.3655688,19z?entry=ttu). As the number of participants is limited, please register at

Some more info on World Wetlands Day
World Wetlands Day (WWD) has drawn attention to the importance of wetlands, including peatlands, every year on February 2 since 1997. On February 2nd the Ramsar Convention, the international agreement for the protection of wetlands, was adopted in 1971. Since last year, it has been recognized as an international day by the United Nations.
Due to pollution, drainage and agriculture, fires and overfishing, wetlands, including peatlands, are under threat or have already been destroyed worldwide. Yet they are guarantors of biodiversity and climate protection. Among other things, they offer people protection from drought and flooding, purify water and regulate the microclimate. In Germany, 95 % of former peatlands have been drained and are no longer recognizable as such today

Start for MOOSland

Peat moss harverst (Photo: Tobias Dahms)

for tiny moss on large scale

11/01/2024 With MOOSland, a small plant is supposed to make a big impact – peat moss. This can be grown as a renewable raw material to replace peat in horticulture with great benefits for the climate and the economy. Over the next ten years, MOOSland wants to implement the cultivation and utilization of peat moss biomass, which has already been researched in pilot projects, on a large scale. When grassland is being rewetted for climate protection reasons, the cultivation of peat moss offers an alternative to current drainage-based agriculture. Peat moss stores water in its cells, up to 30 times its own weight. Thus, it provides a renewable raw material with similar properties to the peat formed from it. It is therefore ideal as a peat substitute. MOOSland will now help to investigate and implement peat moss paludiculture on a large scale in an ecologically, economically and socially compatible way. MOOSland is a model and demonstration project by the University of Greifswald and seven partners from Lower Saxony. The Federal Ministry of Food and Agriculture (BMEL) is supporting the project with a total of around 12.5 million euros from the Climate Transformation Fund (KTF); The project sponsor is the Agency for Renewable Raw Materials (FNR).

Wet again – but no flooding

Flooding on the Koos (Picture: Succow Foundation)

with benefit instead of damage

6/01/2024 It has rained a lot in large parts of Germany in the past few weeks. Many rivers have overflowed their banks, numerous areas are flooded, dikes are giving way and the water is threatening towns and cities. Countless rescue workers and helpers are fighting to limit the damage.
Our use of water is a key reason for the floods: water management today is designed to drain rainwater from the landscape quickly and in a controlled manner. That's why it is crisscrossed with a dense drainage network of ditches, underground drainage pipes, receiving waters, pumping stations, etc. Straightening watercourses also contributes to the water flowing away more quickly. However, when there is high rainfall, this drainage system is overloaded. The water cannot be drained away quickly enough and flooding is the result.
Modeling shows that higher winter precipitation and more heavy rain events are to be expected in the future due to climate change. It therefore becomes even more important to make flood protection safer for the future. Simply thinking about more stable and higher dikes is not enough. Rather, retention areas should be given much greater consideration because they have great importance and great potential for flood protection. Peatlands play a prominent role here. When drained, they can exacerbate flood situations if their peat is degraded and compacted. Wet peatlands, on the other hand, can absorb and store water like a sponge, thus delaying runoff. With a peat formation horizon (so-called acrotelm) in the uppermost decimetres, they are able to “breathe”, so the surface fluctuates depending on the water supply (so-called peat oscillation). Short-term flooding thus does not harm wet peatlands, even if they are used for agricultural purposes in paludiculture. This allows them to buffer flood peaks. This is also why they say “Peatland must be wet!”.
