Incredibly informative and well designed: the new Global Peatland Hotspot Atlas launched in a peatland Side Event at COP29. It presents the most up-to-date data on world’s peatlands in a Global Peatland Map 2.0 visualizing global threats and opportunities for peatlands.

That’s new:

  • maps for each of the six continents
  • thematic maps on biodiversity, permafrost, water supply and more
  • maps on degradation, greenhouse gas emissions, peatland use, environmental risks etc

This Global Peatland Hotspot Atlas is a call to action to place peatlands at the heart of the global environmental agenda! It enables decision makers to scope potential regions for conservation, restoration, and sustainable management, since time to act is now.
The Atlas was issued by UNEP as a product of the Global Peatlands Initiative with maps of the Greifswald Mire Centre.

Applause with reeds

Both are about saying goodbye to combustion, but in very different ways. Franziska Tanneberger and Thomas Speidel received the German Environmental Award for their commitment at an award ceremony end of October.

Functioning in lecture hall, field and parliamentary hearings - peatland researcher Franziska Tanneberger is the kind of scientist you want to meet. And engineer Thomas Speidel has developed the ‘Swiss army knife of electromobility’ to combat Germany's ‘range anxiety’. Secretary General Alexander Bonde and Chairman of the Board of Trustees Kai Niebert told the press before the award ceremony at 27th October at Mainz that choosing the winners of this year's German Environmental Award was not difficult.

Tanneberger and Speidel are saying goodbye to ‘combustion’ - in very different ways. The entrepreneur at ADS-TEC Energy is promoting electromobility with fast charging stations. The scientist at the University of Greifswald and co-director of the Greifswald Mire Centre wants to stop oxidation by draining peat soils and show the opportunities for natural climate protection through wet peatlands. “We must not be satisfied with regularly failing to meet climate targets!” Tanneberger said. She appreciates the prize because it raises awareness of solutions and – in her understanding - honours the work of an entire team of Greifswald Mire Centre. Its representatives waved reeds in applause.

Federal President Frank-Walter Steinmeier also emphasised solutions in his speech: He imagines charging stations to be as commonplace as telephone boxes used to be. They were everywhere, he said, but in peatlands, Steinmeier said. In view of the climate crisis, this landscape’s image is changing from sinister to beneficial. According to Franziska Tanneberger, peatlands send us signals even without a telephone box in them. She would like to use her share of the prize money to fund further research and implementation on climate and biodiversity protection in peatlands and their sustainable use.

About the German Environmental Award: Every year, the German Federal Environmental Foundation (Deutsche Bundesstiftung Umwelt, DBU) honours the achievements of people who make an exemplary contribution to protecting and preserving the environment with the German Environmental Award. The prize is endowed with a total of 500,000 euros and is presented by the Federal President. Here are the media reports from tagesschau and others.

The Paludiculture Interview

The paludiculture print - 3D and with reed and typha

3D printing needs a replacement for petroleum-based plastics. Scientist Jonas-Rumi Baumann is researching how plant fibers can improve the properties of new materials for this purpose at Bremen University of Applied Sciences. He also puts paludiculture plants such as cattails and reeds in his 3D printer.

Read more...

Mr. Baumann, do you constantly print small figurines in the 3D printer for your research - how should we imagine that?

I would like to, but we haven't got that far yet. First of all, we're in the process of developing the printing material. I'm personally fascinated by 3D printing. If a small part on my fridge breaks, I can simply reprint it.

What exactly do you do then?

For us, it's all about compounds - combining plastic with biomass in order to reduce petroleum-based components in products. Plant fibers can improve their properties. Such mixtures are called “natural fiber composites”. I examine the mechanical properties of these new materials using so-called test specimens - test parts. We have already worked with flax, hemp and nettles, but we are always on the lookout for new fibers.

And which paludiculture plants are suitable?

Broad-leaved cattail and reed are the most suitable so far. They have the most interesting mechanical properties. These include stiffness, i.e. how much something deforms elastically and returns to its original position unchanged. Then there is strength: how much the material can withstand before it breaks.

Paper and cardboard made from paludiculture biomass - for example. molded trays - already exist. What is different for 3D printing?

For cardboard or disposable trays, the biomass has to be processed in a completely different way. In the molded fiber packaging s, which is commonly used to produce plastic parts today, the raw material comes in granules and can be processed directly. For 3D printing we need an additional step: develop and produce a thermoplastic wire. This resembles a long metal wire, which is then wound onto a roll. During printing, it is heated to 200 °C and pressed through an opening of 0.4 mm. The workpiece is created layer by layer. We use extremely fine ground biomass for this, which must be evenly mixed with the plastic in a compounder. That in itself is difficult, but thus guarantees the product’s consistent properties. In addition, after drying, biomass often still contains moisture. 1-3%g. This moisture must be removed even though the compounder is actually a closed system. If not, the components cannot be mixed properly. In the end, the printer will not deliver good workpieces.

When the compounds combine - will your existing materials end up on the compost heap or in the residual waste garbage can?

The ideal is a completely compostable composite material. Today we use the plastic polyacetide (PLA), also known as polylactic acid. It is compostable under industrial conditions, for example at a defined temperature, but not yet at home in the garden. Another plastic used is polyhydroxybutyrate (PHB). This degrades under marine conditions, for example. So it's good for combating plastic littering in the oceans.

3D printing still seems to be more of a niche - what does it look like economically? Is there a market?

3D printing will of course not be used to produce yoghurt pots at vast scale. The injection molding process is suitable for large quantities and fast production. We are also developing a material with paludiculture biomass for this purpose.  3D printing is about small quantities, often for the production of prototypes in the home, in research and development. There are more and more printers and their use is increasing. This means that there will also be a demand for bio-based, future-friendly materials for 3D printing.

Will I buy the pressure substance made from bulrush in a cartridge at some point?

Hopefully yes! With 3D printing, it's more of a role than a cartridge. There are already compounds with natural fibers. We hope that a paludiculture 3D printing wire will be competitive, as it has a very good carbon footprint.

Jonas-Rumi Baumann works in Prof. Jörg Müssig's Biological Materials working group at Bremen University of Applied Sciences. His research into paludiculture biomass for 3D printing is part of the NAPALU project.

The interview was conducted by Nina Körner.

Paludiculture Potential in Ukraine

A new compendium explores the possibilities of paludiculture in the currently war-torn Ukraine.

Read more...

Northern Ukraine is the focus of an ambitious project dedicated to peatland rewetting and climate protection. The Succow Foundation, partner of the Greifswald Mire Center, is working together with the United Nations Development Programme (UNDP) on the project “Promotion of sustainable pasture management and ecosystem protection in northern Ukraine”. The project is financed by the Global Environment Facility and the FOLUR platform. The aim of the pilot project is to convert the management of three million hectares to organic farming in order to reduce greenhouse gas emissions, improve soil fertility and protect endangered species.

A central component of the project is paludiculture, the only sustainable form of wet peatland management that helps to reduce carbon emissions by rewetting and using the peatlands. Wendelin Wichtmann and Olga Denyshchyk from the Succow Foundation, partner in the Greifswad Mire Centre, were commissioned to examine the feasibility of paludiculture in Ukraine, taking into account the specific conditions of Ukraine. They compiled a scientifically based compendium, which is now available in Ukrainian.

The compendium is intended for farmers, representatives of local communities, the scientific community, and civil society. Its purpose is to provide a scientific basis for the implementation of internationally recognized environmentally-oriented agricultural practices, particularly on wet peatlands, adapted to the unique conditions of Ukraine. The compendium also provides recommendations for the application of paludiculture practices on restored peatlands, combining environmentally-oriented solutions with economic efficiency.This is the first collection in Ukraine that contains scientific information about paludiculture a sustainable land-use method, already being implemented in European Union member states.

German Projects

Wetscapes 2.0

The German Research Foundation is providing ten million Euros for the Wetscapes 2.0 project over the next four years. The consortium led by the universities of Greifswald and Rostock has thus successfully asserted itself against four competitors.

Read more...

‘WETSCAPES2.0: novel ecosystems in rewetted fen landscapes’ will investigate the functioning and complex ecological, biogeochemical and hydrological processes in rewetted fens. The funding from the German Research Foundation was acquired by the Universities of Greifswald and Rostock together with the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB Berlin), the Helmholtz Centre Potsdam German Research Centre for Geosciences (GFZ), the Ludwig-Maximilians-Universität München (LMU), the Max Planck Institute for Biogeochemistry Jena (MPI-BGC) and the Humboldt-Universität zu Berlin (HU).

The background: peatlands have been drained for centuries, which has led to significant greenhouse gas emissions, nutrient discharge into watercourses and neighbouring ecosystems as well as massive losses of biodiversity. Rewetting programmes across Europe are now intended to reverse these negative effects. However, this is not restoring the original peatlands, but creating new types of ecosystems, the functioning of which is still only partially understood.

The research network aims to better understand the functioning and complex ecological, biogeochemical and hydrological processes in rewetted fens. It will investigate the effects of rewetting peatlands in space and time at landscape level and beyond. In the long term, concrete contributions to the management of these areas and to sustainable utilisation through paludiculture will be developed.

WETSCAPES 2.0 strengthens cutting-edge research in Mecklenburg-Western Pomerania and also makes a decisive contribution to addressing global challenges such as climate change and biodiversity loss and advancing nature-based solutions locally. Knowledge transfer and the communication of research topics for greater social acceptance will take place in close cooperation with the Greifswald Mire Centre.

The DFG's Collaborative Research Centres (SFB) are long-term research institutions at universities in which scientists work together as part of an interdisciplinary research programme. Innovative, challenging, complex and long-term projects can be realised in the Collaborative Research Centres by coordinating and concentrating people and resources at the applicant universities. They serve to develop institutional priorities and structures.

Peatland sound & light art

The exhibition EIN:FLUSS:RAUM:MOOR has interwoven data, light projection and sound recordings to create a walk-in sculpture which also interactivly involves the visitor.

Read more...

EIN:FLUSS:RAUM:MOOR, the joint exhibition by MONAS-Collective and Greifswald Mire Centre, presented peatland in a sound and light artwork inspired by Caspar David Friedrich and his fascination with landscape. In the painter's anniversary year, the exhibition was on display from October 31st - December 8th at the Spielhalle Kunst in Greifswald. It combined climate data, audio recordings, light projections and exhibits. The artists captured the sound with ground microphones at the Kieshofer Moor and Karrendorfer Wiesen near Greifswald. Combined with data from greenhouse gas measurements by scientists of Greifswald Mire Centre, these were converted into light pulses in the exhibition. The visitors present also influenced the system, as the installation also measured CO2 values in the room in real time, for example. This film conveys the exhibition’s unusual experience of beauty and significance of the peatland landscape in this sound and image sculpture. By the way - the peat mosses as part of the exhibition are contributions from the MOOSstart and MOOSland projects.

Peatland projects at Germany’s Baltic coast

Networked diversity on the Treasure Coast and peatland climate protection on the Baltic Sea coast are official UN Decade of Ecosystem Restoration projects.

Read more...

The OSTSEESTIFTUNG submitted two projects to the UN Decade project competition on marine and coastal ecosystems - and both reached the final round and can now hold the title ‘TOP 10 Project 2024’. This title was awarded on 3rd September to projects that are particularly committed to the restoration, conservation or maintenance of ecosystems in Germany.

Both projects, the joint project Networked Diversity on the Treasure Coast, which has been active since 2021, and the project Peatland Climate Protection on the Baltic Sea Coast, which was approved in spring 2024, are coordinated by the OSTSEESTIFTUNG and implemented in collaboration with partners. The coastal landscape of Mecklenburg-Western Pomerania is at the centre of both projects.

‘We are delighted to receive this award,’ says Georg Nikelski, Managing Director of the OSTSEESTIFTUNG, ’which also recognises our many partners and supporters across the region. Those involved on the ground are ultimately the ones who ensure that restoration projects and plantings are preserved and maintained. Coastal peatlands, field hedges and reed beds are important ecological niches that provide habitats for many endangered key species,’ says Nikelski.

As part of the Baltic Sea coastal peatland climate protection project, several diked sections of coastline between Rostock and the Polish Baltic Sea are to be restored by 2034, covering an estimated total area of 850 hectares. The aim is to significantly reduce the ongoing release of climate-damaging gases such as CO2. Gerald Jurasinski, Professor of Peatland Science at the University of Greifswald, partner in the Greifswald Mire Centre, and Professor Maren Voß from the Leibniz Institute for Baltic Sea Research Warnemünde are responsible for the accompanying scientific research as partners of the OSTSEESTIFTUNG.

The data and knowledge gained over the years will enable a more effective approach to the restoration of coastal peatlands with predictable effects for climate and nature conservation in the future. The project is funded by the Federal Agency for Nature Conservation (BfN) as part of the Natural Climate Protection Action Programme with funds from the Federal Ministry for the Environment, Nature Conservation, Nuclear Safety and Consumer Protection (BMUV) and the state of Mecklenburg-Western Pomerania.

PaludiNetz soil workshop in Hammeniederung and Teufelsmoor

In September, a workshop on addressing and describing peat soils focused on how trafficability can be comparably measured as part of the PaludiZentrale joint project.

Read more...

Researchers from the Thünen Institute in Braunschweig conducted a workshop with experts from the PaludiNetz projects on addressing and describing peat soils and a test on the comparability of measurements on trafficability as part of the PaludiZentrale joint project.

Information on the initial condition of a peatland soil is of crucial importance for the successful implementation of rewetting measures and the establishment of paludicultures, which is the aim of the PaludiNetz projects. It can be charcterised  both by their natural development history and by anthropogenic interventions such as drainage and agricultural utilisation. However, overarching statements are only possible if peatland soils are analysed and described using comparable criteria and methods. In order to establish cross-project methods, the PaludiZentrale joint project of Thünen Institute, University of Greifswald and Succow Foundation held a soil workshop in Osterholz-Scharmbeck from 25th-27th September 2024. which was attended by experts.

The workshop was a complete success for both organisers and participants and laid a further basis for successful collaboration in the PaludiNetz in the coming years. Special thanks go to the two local farmers who made their land available for the workshop. PaludiZentrale is funded by the Federal Ministry of Food and Agriculture (BMEL) from the Special Climate and Transformation Fund through the Agency for Renewable Resources (FNR).

Conference “MENSCHEN.MACHEN.MOORE.”

At the final conference of the MoKKA project “MENSCHEN.MACHEN.MOORE.” on November 7th in Schwerin, 140 participants discussed why more capacity is needed for peatland climate protection.

Why is more capacity needed for peatland climate protection? And how can this be set up? At MENSCHEN.MACHEN.MOORE., the final conference of the project “Peatland Climate Protection through Capacity Building” (MoKKA), around 140 experts and interested participants came together in Schwerin on November 7th to discuss these questions. Legal hurdles, deficits in education and training and the need for support for project sponsors of peatland projects were addressed in presentations, discussion rounds and workshops. The conference also highlighted the urgency of structural and educational policy measures for peatland climate protection.

The welcome speech  was given by Dr. Franziska Tanneberger (Greifswald Mire Centre) and Georg Nikelski (OSTSEESTIFTUNG), accompanied by words of welcome from State Secretary Elisabeth Aßmann from the Ministry for Climate Protection, Agriculture, Rural Areas and the Environment of Mecklenburg-Western Pomerania and Helmut Alda from the Federal Ministry for the Environment, Nuclear Safety and Consumer Protection. “You have been doing a very, very good job for many, many years. Thank you very much for that. We are trying to provide the best possible support and take care of the legal and funding issues. And I believe that together we can still achieve a great deal in the coming years and decades. Because Menschen Machen Moore Nass!“, said Elisabeth Aßmann.

Afterwards, Christina Lechtape (Michael Succow Foundation/Greifswald Mire Centre), MoKKa project coordinator, gave a keynote speech on which stakeholder groups are particularly important for peatland climate protection, what they need for more implementation and how they can be supported. “We need more networking and knowledge transfer in the field of peatland climate protection! The interest is there, but the capacities and opportunities are still very limited. Actors who want to take concrete action or implement projects need suitable training and individual advice,” said Christina Lechtape, MoKKa.

The first session dealt with the question of how planning and approval can be accelerated and how land availability can be improved. Keynote speeches by Sophie Hirschelmann (Michael Succow Foundation/Greifswald Mire Centre) and Prof. Sabine Schlacke (Institute for Energy, Environmental and Maritime Law, University of Greifswald) addressed legal hurdles and obstacles in procedures as well as possible framework conditions. Representatives from the BMUV, LM MV and the Brandenburg State Office for the Environment took part in the subsequent discussion on specific solutions. At the same time, the workshop “Peatland climate education with the peatland suitcase” took place, in which the Succow Foundation's new methods for educational work in the field of peatland climate protection were presented and tested in practice. The workshop was led by Hannah Marx (Michael Succow Foundation/Greifswald Mire Centre). After the lunch break, the program continued with a joint activity in which the participants played different roles in a moor. In the afternoon, the topic of “Building support structures” was addressed. First, the user perspective offered insights into the practical requirements and experiences of peatland projects through short impulses from participants of the field days and short films from the project).

The institutional perspective was then included, with presentations by Dr. Almut Mrotzek (MoorAgentur MV) and Tom Kirschey (Competence Center for Natural Climate Protection), who reported on support options and funding structures. Finally, the focus was on the question "More peatland formation - when and how?" In her keynote speech, Tabea Feldmann made clear that sustainable development in Germany is only possible if peatlands become part of general education. A panel discussion with Dr. Martina Trümper (Ministry of Education and Child Daycare Support MV) and Prof. Gerald Jurasinski (University of Greifswald) examined how the topic of peatland climate protection can be better integrated into education and training in order to create social awareness of the importance of peatlands.
