CLIMATE CHANGE 56/2022 - Interim report - Role of soils in climate

1 Dec 2022

The working definition was developed in the context of this research project and is based on the IUCN definition and the definition by the UNEA 5.2 Resolution 5 on NbS.1 The mitigation potential associated with nature-based soil management is examined at global, EU and German level (chapter 2). [...] Uncertainties around the range of mitigation potentials of peatlands are linked to varying estimates for degraded peatland areas and for the full implementation of the global restoration potential, and to the emission factors reflecting the different phases of peat degradation. [...] The rewetting of organic soils, the conversion from arable to grassland, as well as management and conversion to silvopastoral and silvoarable agroforestry systems have the highest absolute mitigation potential in the EU and in Germany, according to available data. [...] The effects on the climate involve the GHG emissions due to the destruction of soil profile that enhances the loss of existing SOC stocks and the loss of future carbon sequestration potential. [...] Uncertainties remain in the estimates of the mitigation potentials both at the level of individual soil management measures, as well as at the level of aggregate assessments.
