Short summary
The study looked at published data on drained organic forest soils in boreal and temperate zones to revisit current Tier 1 default emission factors (EFs) provided by the IPCC Wetlands Supplement. We examined the possibilities of forming more site-type specific EFs and inspected the potential relevance of environmental variables for predicting annual soil greenhouse gas balances by statistical models. The results have important implications for EF revisions and national emission reporting.

A 2-year study assessed the soil carbon dioxide (CO2) balance of drained and undrained hemiboreal peatland forests across Estonia, Latvia, and Lithuania. The study sites included a wide variety of nutrient-rich organic soils, ranging from those near the threshold of organic soil definition to deep peat soils. The soils varied in pH, nutrient levels, and C : N ratio, which contributed to the observed behavior of the soils, demonstrating CO2 sink and source dynamics under both drained and undrained conditions.

Short summary
Estimates of CO2 fluxes from drained nutrient-rich organic soils in croplands and grasslands in the hemiboreal region of Europe revealed that annual net CO2 fluxes were lower than the latest (2014) IPCC (Intergovernmental Panel on Climate Change ) emission factors provided for the whole temperate zone, including the hemiboreal region. The contribution of CO2 fluxes from shallow highly decomposed organic soils, former peatlands that no longer meet the IPCC criterion for organic soils, to total emissions can be high and should not be underestimated.

Redox potential, indicative of the active pathways of organic matter decomposition, was monitored for 2 years in a boreal peatland with three drainage regimes. Contrary to expectations, the water table level and redox potential were not found to be correlated in a monotonic fashion; thus, the relationship between the water table level and redox conditions is not modellable using non-dynamic models.

The emissions of greenhouse gases (GHGs) carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) were measured from a clear-cut peatland forest site. The measurements covered the whole year of 2022, which was the second growing season after the clear-cut. The site was a strong GHG source, and the highest emissions came from CO2, followed by N2O and CH4. A statistical model that included information on different surfaces at the site was developed to unravel surface-type-specific GHG fluxes.

Short summary
Drainage of boreal peatlands strongly influences soil methane fluxes, with important implications for climatic impacts. Here we simulate methane fluxes in forestry-drained and restored peatlands during the 21st century. We found that restoration turned peatlands into a source of methane, but the magnitude varied regionally. In forests, changes in the water table level influenced methane fluxes, and in general, the sink was weaker under rotational forestry compared to continuous cover forestry.

Updating the Yasso07 soil C model's dependency on decomposition with a hump-shaped Ricker moisture function improved modelled soil organic C (SOC) stocks in a catena of mineral and organic soils in boreal forest. The Ricker function, set to peak at a rate of 1 and calibrated against SOC and CO2 data using a Bayesian approach, showed a maximum in well-drained soils. Using SOC and CO2 data together with the moisture only from the topsoil humus was crucial for accurate model estimates.

A two-year study in Estonia, Latvia, and Lithuania evaluated forest organic soil carbon balance and the impact of drainage. CO2 emissions from soil did not significantly differ, showing a uniform methodology should be applied in national greenhouse gas inventories. Neither drained or undrained soils lost carbon during the study period. However, it was estimated that the negative impact of drainage on carbon sequestration in hemiboreal forest soils is 0.43±2.69 t C ha−1 year−1.

Current and future nitrous oxide (N2O) emissions are difficult to estimate due to their high variability in space and time. Several years of N2O fluxes from drained boreal peatland forest indicate high importance of summer precipitation, winter temperature, and snow conditions in controlling annual N2O emissions. The results indicate increasing year-to-year variation in N2O emissions in changing climate with more extreme seasonal weather conditions.

We measured and modelled the CO2 and CH4 fluxes of the terrestrial and aquatic ecosystems of the subarctic landscape for 2 years. The landscape was an annual CO2 sink and a CH4 source. The forest had the largest contribution to the landscape-level CO2 sink and the peatland to the CH4 emissions. The lakes released 24 % of the annual net C uptake of the landscape back to the atmosphere. The C fluxes were affected most by the rainy peak growing season of 2017 and the drought event in July 2018.

We measured CO2 and CH4 fluxes in heterogenous Arctic tundra in eastern Siberia. We found that tundra wetlands with sedge and grass vegetation contributed disproportionately to the landscape's ecosystem CO2 uptake and CH4 emissions to the atmosphere. Moreover, we observed high CH4 consumption in dry tundra, particularly in barren areas, offsetting part of the CH4 emissions from the wetlands.

Short summary
In Finland peatlands cover one-third of land area. For half of those, with 4.3 Mha being drained for forestry, Finland reports sinks and sources of greenhouse gases in forest lands on organic soils following its UNFCCC commitment. We describe a new method for compiling soil CO2 balance that follows changes in tree volume, tree harvests and temperature. An increasing trend of emissions from 1.4 to 7.9 Mt CO2 was calculated for drained peatland forest soils in Finland for 1990–2021.
