Russia has the biggest location of forest in the world, with more than a fifth of the world’s trees. A brand-new research study, led by Russian researchers utilizing information from ESA’s Climate Change Initiative, has actually produced brand-new price quotes of biomass included in Russian forests, and validates that the large forested location is saving more carbon than formerly approximated.
The research study, released last month in Nature Scientific Reports, approximates that Russian forests consist of 111 billion cubic meters (~3.9 trillion cubic feet) of wood since 2014 – which relates to 39% greater than the worth reported to the Food and Agriculture Organization of the United Nations (FAO) and the United Nations Framework Convention on Climate Change (UNFCCC).
The research study utilizes satellite-based maps of forest biomass, produced by ESA’s Climate Change Initiative (CCI) Biomass task, integrated with Russian ground-based measurements, such as information from the National Forest Inventory and the ESA-supported Forest Observation System, to get more precise figures of carbon saved in forests.
Remote-noticing research studies have actually currently suggested boosts in plant life performance and tree cover over the previous years. Yet Russia has actually reported practically no modification in growing stock (+ 1.8%) and biomass (+ 0.6%) given that the collapse of the Soviet Union and shift to a brand-new forest stock system.
This brand-new quote remains in line with the arise from the National Forest Inventory, however broadens its capability in regards to spatial and temporal representation. It is anticipated to have a significant effect on how Russia reports its forest carbon stock.
“The paper demonstrates that the current methodology for UNFCCC reporting needs updating. The method of using satellite-based data that is validated with ground-based measurements is best-placed to help with this,” states the research study’s lead author Dmitry Schepaschenko, a scientist with the International Institute for Applied Systems Analysis in Austria (IIASA).

“Ground surveying is crucial in measuring biomass. However, the first forest national inventory cycle took 14 years in a country that’s as large as Russia, and is expected to provide a robust estimate at a national scale only. The combination of ground and space-based data has allowed us to provide the results for specific years in a higher spatial resolution and reduce uncertainties of the estimates.”
He continues: “Our team include representatives of Russian academic institutes, people from the National Forest Inventory and Forestry Agency – which ensures the impact on national policy.”
The authors utilize the last Soviet Union report as a recommendation, and they discovered that Russian forests built up 1 billion cubic meters annually in between 1988–2014, which stabilizes the net forest stock losses reported in tropical nations.
The group discovered that the sequestered carbon over the exact same duration was 47% greater than that reported in Russia’s UNFCCC National Greenhouse Gases Inventory.
But they alert that the forest gains won’t always continue in the long-lasting: “Whilst we found that Russian forests have been a more important carbon stock than previously thought, the situation is changing after 2014 because of the increasing severity of forest disturbances,” states Schepaschenko.

Forest disruptions can consist of forest fires, consisting of those presently happening in the Sakha-Yakutia area of Siberia, which have actually burned through 1.5 million hectares of land. The fires have actually shrouded Yakutia’s cities and towns in thick smoke, suspending all flights at the local capital’s airport. In action to the wildfire, the International Charter Space and Major Disasters has actually been triggered.
The brand-new nationwide quote and unpredictability make a crucial contribution to enhancing ESA’s maps of above ground biomass saved by forests on a global-scale by means of ESA’s Climate Change Initiative Biomass task. The authors’ ground-based measurements will likewise assist verify brand-new satellite observations of biomass that will be supplied by ESA’s upcoming Biomass objective.
