Globally, 10–20% of peatlands have been drained for agriculture or forestry, and they emit close to 5% of global anthropogenic CO2 emissions. There are countries in Europe that have more than 60% of their agricultural emissions originating from cultivated organic soils, and the fate of South-East Asian peatlands is of global concern. Drainage causes losses of specialized species and further ecosystem services such as nutrient retention. However, most peatland-rich countries address peatlands poorly in national emission reporting and climate change mitigation strategies.
Innovative mitigation measures that sustain economically viable biomass production while reducing negative environmental impacts including greenhouse gas emissions, fire risk and supporting ecosystem services of organic soils are currently vigorously studied. Management measures include, but are not limited to, productive use of wet peatlands (“paludiculture”), improved water management in conventional agriculture and innovative approaches in conservation-focused rewetting projects. Production systems where peatland water table is 40 cm below the surface or higher, can generate food (e.g. fish, berries, mushrooms), feed (e.g. fodder for livestock), fiber (for construction, furniture) and fuel, and raw materials for chemical industry. How to implement these innovations in practice and integrate them into national GHG inventories remains a challenge.
We invite studies addressing peat-preserving management practices on organic soils as well as their implementation into GHG inventories. Work on all spatial scales from the laboratory to the national level addressing biogeochemical as well as biological aspects and both experimental and modelling studies are welcome. Especially research on development of traditional systems with details on commodities with viable value chains and income generation would be of interest. Furthermore, we invite contributions that address policy coherence and identify policy instruments for initiating and implementing new management practices on organic soils.
This session is organized as a joined effort of Global Research Alliance “Peatland Management” working group, Global Peatlands Initiative, Greifswald Mire Center, Thünen Institute and RePeat (REstoration and prognosis of PEAT formation in fens - linking diversity in plant functional traits to soil biological and biogeochemical processes 2016-2019; BiodiVErSA) and PeatWise (Wise use of drained peatlands in a bio-based economy: development of improved assessment practices and sustainable techniques for mitigation of greenhouse gases 2017-2020; FACCE ERA-GAS) – projects.
