“…'Relative year zero' is the fire year, negative values are pre-fire years (for example, '−1' year means one year before fire) and positive values are post-fire years (for example, '2' year means the second year after fire). Then, at the ith year after fire, the recovery ratio (Recoveryi (%)) is calculated from pre-fire live AGC (AGC−1) and live AGC at ith year in the post-fire period (AGCi) using equation (9). Thus, the recovery ratio for each year was plotted in Fig.…”

“…In response to warmer temperatures, a longer growing season 3 and widespread 'greening' seen by optical remote-sensing data 4,5 have been reported. These changes are generally interpreted as increases in above-ground biomass carbon (AGC) 6 and CO2 uptake 7,8 , and the prevailing view is that Siberian forests have acted as a net sink for atmospheric CO2 during recent decades [9][10][11][12][13] .…”

Siberian carbon sink reduced by forest disturbances

Siberian forests are generally thought to have acted as an important carbon sink over recent decades, but exposure to severe droughts and fire disturbances may have impacted their carbon dynamics. Limited available forest inventories mean the carbon balance remains uncertain.Here we analyse annual live and dead above-ground carbon changes derived from low-frequency passive microwave observations from 2010 to 2019. We find that during this period, the carbon balance of Siberian forests was close to neutral, with the forests acting as a small carbon sink of +0.02 +0.01 +0.03 PgC yr −1 . Carbon storage in dead wood increased, but this was largely offset by a decrease in live biomass. Substantial losses of live above-ground carbon are attributed to fire and drought, such as the widespread fires in northern Siberia in 2012 and extreme drought in eastern Siberia in 2015. These live above-ground carbon losses contrast with 'greening' trends seen in leaf area index over the same period, a decoupling explained by faster post-disturbance recovery of leaf area than live above-ground carbon. Our study highlights the vulnerability of large forest carbon stores in Siberia to climate-induced disturbances, challenging the persistence of the carbon sink in this region of the globe.

“…В рамках первого цикла проекта, завершенного в конце 2020 г. Обращает на себя внимание, что оценка по РОБУЛ (590,6 млн т) является минимальной из известных оценок объема поглощения углерода (парниковых газов) лесами и в целом вклада в этот процесс сектора ЗИЗЛХ. Другая методика, разработанная во Всероссийском научно-исследовательском институте лесоводства и механизации лесного хозяйства (ВНИИЛМ), как и РОБУЛ, в качестве информационной базы расчетов использует данные ГЛР, однако существенно отличается в способах расчетов [10,11,14].…”

Recent inclusion of the issue of economy decarbonization in the global agenda has been affecting social and political priorities. To lower greenhouse gas emissions, Russian economy has to reduce anthropogenic emissions and maximise the carbon sequestration potential of national forests. The paper demonstrates that Russian forest ecosystems compensate for more than a quarter (almost 27 %) of anthropogenic emissions. However, due to the absence of a reliable, time-tested forest inventory system in Russia, as opposed to leading countries, it is difficult to ensure the sustainable use of forest resources and full accounting of greenhouse gas absorption by forests. The research analyses systemic measures to improve the absorptive capacity of Russian forests as a key element of the mechanism for compensating industrial greenhouse gas emissions, since the global expert community should recognise the contribution of these forests to the global climate change mitigation. Potential economic benefits of increasing the carbon-absorbing capacity of forests are assessed at the regional level. The example of Irkutsk oblast shows that the calculated effect of the analysed measures can amount to 6–7 dollars/ha at the current price of carbon credits; full implementation of these measures in the region can bring up to 480 million US dollars annually, net of expenses. The research proposes to ensure the necessary quality and completeness of data of the State Forest Registry by integrating remote and ground-based field measurements. It is also suggested to enhance institutional and investment support to state forest conservation initiatives, including in the framework of the National Project “Ecology” and forest-climate projects based on public-private partnerships. These measures should be included in the reform of public policy in the field of forest management.

“…The world's boreal forest, and the transition zone from the boreal forest to the tundra zone to the north of it, has a high importance for biodiversity and in modulating the global carbon and water cycles Callaghan, Werkman & Crawford, 2002;Hofgaard, Harper & Golubeva, 2012;Rees et al, 2020). This importance is not matched by our current level of knowledge of this extensive zone, and the problem is particularly acute in Russia (Alekseev, Tomppo, McRoberts & von Gadow, 2019;Filipchuk, Moiseev, Malysheva & Strakhov, 2018). Roughly half of the Russian forests were last surveyed more than 25 years ago (Alekseev et al, 2019), while areas of tundra generally receive less attention than forest Northern high latitudes can be regarded as a "hotspot" of global warming through the phenomenon of "Arctic amplification" (Previdi, Janoski, Chiodo, Smith & Polvani, 2020), and vegetation is expected to respond directly to climate change (Diffenbaugh & Field, 2013) and indirectly through alterations in fire regimes and anthropogenic disturbance (Hofgaard et al, 2010).…”

Three decades of remote sensing subarctic vegetation in northern Russia: A case study in science diplomacy

The vegetation at and beyond the northern edge of the world’s boreal forest plays an important though imperfectly understood role in the climate system. This is particularly true within Russia, where only a small proportion of the boreal land area has been studied in depth, and little is known about its recent evolution over time. We describe a long-term collaboration between institutions in Russia and the United Kingdom, aimed at developing a better understanding of high-latitude vegetation in Russia using remote sensing methods. The focus of the collaboration has varied over time; in its most recent form, it is concerned with the dynamics of the Russian boreal forest during the 21st century and its relation to climate change. We discuss the support framework within which it has been developed and reflect on its relationship to science diplomacy. We consider the factors that have contributed to the success of a decades-long international collaboration and make recommendations as to how such joint efforts can be encouraged in future.
