Methane and rewetting
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.

Together for Europe's peatlands
GMC team in on the action
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. A team from the Greifswald Mire Centre will also play its part.
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?
10 must-knows from the world of research
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.
