Assessing the climate benefits of afforestation in the Canadian Northern Boreal and Southern Arctic

Nature Communications, Journal Year: 2025, Volume and Issue: 16(1)

Published: Feb. 25, 2025

Abstract Afforestation greatly influences several earth system processes, making it essential to understand these effects accurately assess its potential for climate change mitigation. Although our understanding of forest-climate interactions has improved, significant knowledge gaps remain, preventing definitive assessments afforestation's net benefits. In this review, focusing on the Canadian northern boreal and southern arctic, we identify synthesize existing knowledge. The review highlights regional realities, Earth's climatic history, uncertainties in biogeochemical (BGC) biogeophysical (BGP) changes following afforestation, limitations current assessment methodologies, emphasizing need reconcile before drawing firm conclusions about benefits afforestation. Finally, propose an framework which considers multiple forcing components, temporal analysis, future contexts, implementation details. We hope that research discussed inform afforestation policy Canada other circumpolar nations.

Afforestation on Abandoned Croplands in China Has the Potential to Increase Carbon Sequestration by half

Research Square (Research Square), Journal Year: 2025, Volume and Issue: unknown

Published: March 4, 2025

Afforestation of abandoned cropland represents a promising strategy for land-based climate change mitigation, particularly in regions where land resources additional afforestation are limited. However, the carbon sequestration potential such remains largely unknown. Here, we assess spatial distribution China and its through incentives, using 10,818 empirical data derived from 298 peer-reviewed articles, multisource remote sensing data, machine learning models. We identify 6.03 Mha that have been undergoing natural regeneration since early 21st century. This has to sequester an 215.12–218.94 Tg biomass 15.87–17.64 soil organic (SOC) by 2060, representing 51.95–53.94% increase compared alone. Our results further show benefits could offset 47.71–49.57% government investments (approximately USD 16.254 billion) cropland. findings highlight significant on support China’s neutrality goals, while also offering cost-benefit framework guide policy decisions.

Climate change mitigation through woodland caribou (Rangifer tarandus) habitat restoration in British Columbia

Environmental Research Ecology, Journal Year: 2025, Volume and Issue: 4(2), P. 025004 - 025004

Published: April 1, 2025

Abstract Climate change poses a significant global threat, requiring rapid and effective mitigation strategies to limit future warming. Tree planting is commonly proposed readily implementable natural climate solution. It also vital component of habitat restoration for the threatened woodland caribou ( Rangifer tarandus) . There potential goals conservation carbon sequestration be combined co-benefits. We examine this opportunity by estimating impacts tree in range British Columbia (BC), Canada. To do so, we couple Landsat-derived datasets with Physiological Processes Predicting Growth, process-based model forest growth. compare informed needs maximum under multiple scenarios including shared socio‐economic pathways (SSP) 2, representing ∼2.7 °C warming, SSP5, ∼4.4 Trees were modelled as planted 2025.

They underscore value models evaluating implications areas changing climate.
