Summary: Siberian forests have been considered an important carbon sink, but severe droughts and fire disturbances may have affected their carbon dynamics. Limited forest inventories have led to uncertainties in the carbon balance. This study analyzed microwave observations from 2010 to 2019 and found that the carbon balance of Siberian forests was close to neutral, with a small carbon sink. Fire and drought caused significant losses of live above-ground carbon, contrasting with the greening trends in leaf area index. This highlights the vulnerability of large forest carbon stores in Siberia to climate-induced disturbances.

Summary: This study proposes an approach to map the carbon stock of each individual tree at the national scale of Rwanda using aerial imagery from 2008 and deep learning. The results show that 72% of the mapped trees are located in farmlands and savannas, and 17% in plantations, accounting for 48.6% of the national aboveground carbon stocks. Natural forests cover 11% of the total tree count and 51.4% of the national carbon stocks, with an overall carbon stock uncertainty of 16.9%. The mapping of all trees is crucial for effective planning and monitoring of restoration activities, as well as optimization of carbon sequestration, biodiversity, and economic benefits.

Summary: We assessed the distribution, density, cover, size, mass, and carbon content of over 9.9 billion trees in the semi-arid sub-Saharan Africa north of the Equator using satellite data, machine learning, and high-performance computing. The average carbon stocks of individual trees ranged from 0.54 Mg C ha(-1) and 63 kg C tree(-1) in the arid zone to 3.7 Mg C ha(-1) and 98 kg tree(-1) in the sub-humid zone. Overall, we estimated the total carbon for our study area to be 0.84 (& PLUSMN;19.8%) Pg C. Comparisons with previous simulation studies showed discrepancies in tree density and carbon stocks. We provide a linked database for scientists, policymakers, practitioners, and farmers to estimate farmland tree carbon stocks.

Summary: This study develop data-driven models to predict woody cover in Africa and find that woody cover can be accurately modeled using Random Forest. The simulations based on CMIP6 precipitation data project an overall increase in woody cover at the continental scale by 2100. However, this increase is mainly observed in regions with annual precipitation less than 1,600 mm, while higher rainfall areas are predicted to experience a decrease in woody cover. These results suggest that climate change may lead to changes in the functioning of dryland ecosystems and a loss of carbon stocks in humid areas.

Summary: Changes in terrestrial carbon storage under environmental and land-use changes are crucial for regional and global carbon budgets. This study used L-band microwave vegetation optical depth to generate global maps of annual live vegetation biomass, and found that boreal and temperate forests contribute the most to the global carbon sink, while wet tropical forests serve as small carbon sources. Additionally, the study revealed that tropical deforested and degraded old-growth forests are nearly carbon neutral, while young and middle-aged forests in temperate and boreal regions are the largest sinks.

Summary: Using high-resolution satellite data from 1986 to 2020, our analysis reveals the complex spatiotemporal patterns of southern China's forest transition. We find that the surge in forest area around 2010 is due to the growth of trees planted after 2000, which formed dense forests about a decade later. Our study documents the densification and expansion of forests in a country that had been largely deforested three decades ago.

Summary: Sustainable tree resource management is crucial for mitigating climate warming, fostering a green economy, and protecting habitats. In this study, a deep learning-based framework was developed to provide location, crown area, and height information of individual overstory trees from aerial images at the country scale. The results showed a low bias in identifying large trees and highlighted the significant contribution of trees outside forests to total tree cover, which is often overlooked in national inventories. However, the framework had a higher bias when evaluating all taller trees, including small or understory trees that are undetectable. Moreover, the framework was easily transferable to data from Finland, despite different data sources.
