Abstract/Summary:
Restoring peatland ecosystems is based in many cases on rewetting practices. 2013 Wetlands Supplement (IPCC 2014) considers drainage-rewetting as the activity changing the GHG sinks and sources ratio. Preventing losses of carbon accumulated in peat deposits is an effective measure for climate change mitigation. The high uncertainty in the accounting of carbon emission reduction by peatland rewetting is an obstacle to related reporting. The adaptation effect of peatland restoration could be assessed through the enhancing of ecosystem services. The accounting of ecosystem services gain at the project level is also not a straightforward procedure. The research was aimed to identify the indicators for the assessment of peatland restoration progress, that are also compatible with climate reporting under the Nationally Determined Contributions (NDCs). The evaluation was carried out at the peatland restoration site level and for the entire administrative land unit. Geographic scope – the temperate zone of the Central Part of the European Russia and the West Siberia and permafrost ecosystems in the Nenets Autonomous Okrug in the Arctic. At the restoration site level, the calculations of GHG reduction were still uncertain because of the leakages and high spatial and temporal variation of fluxes. For the administrative area, the reduction was assessed using the Tier 2 approach for the limited number of the land classes and given emission factors. The ecosystem services assessment and evaluation of gains due to the restoration were precise enough to be applied to report climate change adaptation. Peatland restoration is recommended as a nature-based solution for meeting the NDC by the Russian Federation. However, using carbon voluntary market mechanisms at the site level demands considerable investments in the monitoring systems.
