“…The sum of hayfields, pastures and steppes turned out to be higher than the total area of grasslands in the state statistics, which may also indicate overestimation of the areas of natural steppes outside forage lands. A recent paper by the authors of this assessment obtained roughly the same results [28]. In this study, the areas of grasslands and fodder lands are harmonized with the data of the Russian Land Cadastre [17].…”

“…Regional estimates of CO2 balance on the territory of the Russian Federation were made using the approximation method or book-keeping models (BK-Apr). To implement this approach, the areas of steppe ecosystems and average specific (expressed per unit area) values of CO2 fluxes in the ecosystem (NEE, NPP and MR) were used [27,28].…”

In order to achieve global climate goals, it is necessary to estimate greenhouse gases (GHG) fluxes from ecosystems. To obtain a comprehensive assessment of CO2, СН4, N2O natural fluxes for the Russian Federation we used the "bottom-up" method according to [1]. We updated estimates for forest ecosystems based on State Forest Inventory data and satellite monitoring of forest disturbances. For grassland ecosystems, it was based on the correct distribution of areas between steppe and non-steppe zones. The estimated net uptake of natural ecosystems of Russia was 1.1 ± 1.8 billion tons of CO2-eq./year. The study shows that if only CO2 is taken into account, the net absorption of terrestrial ecosystems in Russia corresponds to more than -2.5 billion tons of CO2 (35% of forests’ contribution). However, given the emissions of non-CO2 GHGs, total net absorption in Russia’s natural ecosystems is reduced to about -1 billion tons of CO2-eq (with the forests’ contribution increasing to 80%). With regard to anthropogenic fluxes, the overall balance of GHGs in Russia corresponds to net-emissions of 1 billion tons of CO2-eq/year into the atmosphere. To improve reporting under the Paris Agreement, countries should aim to include only anthropogenic ("manageable") GHG fluxes on managed land.

“…Основные мониторинговые наблюдения за дыханием почв приходятся на лесные и болотные экосистемы, в то время как травяные ценозы остаются малоизученными [Курганова и др., 2019]. При этом их вклад в создание положительного углеродного баланса на территории России довольно значителен [Golubyatnikov et al, 2023].…”

The article demonstrates the results of estimating the respiration from the surface of alluvial meadow soils in the Selenga River Delta. The CO 2 emissions were measured from 2015 to 2017 (May-September) using chamber method. It has been found that the dynamics of the soil CO 2 emissions are influenced by several factors: season, organic matter content, and hydrothermal conditions. Soil hydrothermal conditions primarily determine the intensity and characteristics of the seasonal dynamics of the soil CO 2 fluxes. The temperature of the upper soil layer played a determining role in the changes in the rate of CO 2 release from the soil during the vegetation season. Moisture conditions do not play a significant role in the formation of the carbon dioxide flux.
