Biodiversity - how to save it?

10 must-knows from the world of research

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

Good news: There are only six years left to achieve the biodiversity targets, but we can make it! We can do quite a lot to effectively conserve biodiversity at local, national and European level, on the ground as well as on in society and 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 - thanks to Greifswald Mire Centre and the University of Greifswald ;) - 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 to focus on ecosystems functioning rather than on individual species. Environmental measures can thus become more sustainable. The "10 must-knows from biodiversity research" provide facts for a German National Biodiversity Strategy 2030, which is currently being developed. This will enables 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

#savethedate

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's 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 year, 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, nature and landscape. The salon evening on February 22 at 7 p.m. in Ellernholzstr. 1-3 is free of charge, but registration is required.

PaludiZentrale

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 (https://www.google.de/maps/@54.0923148,13.3655688,19z?entry=ttu). As the number of participants is limited, please register at bibliothek@greifswaldmoor.de.

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.
