Spatial Database of Planted Trees (SDPT Version 2.0)

Published: March 1, 2024

This paper describes the methods for updating Spatial Database of Planted Trees (SDPT) in three areas: boundaries, to spatially differentiate planted forests and tree crops from natural seminatural on a global scale; species information, help screen illegal exportation timber products; carbon sequestration rates, or removal factors, improve maps atmospheric dioxide by trees.

Cost-effectiveness of natural forest regeneration and plantations for climate mitigation

Nature Climate Change, Journal Year: 2024, Volume and Issue: 14(9), P. 996 - 1002

Published: July 24, 2024

Abstract Mitigating climate change cost-effectively requires identifying least-cost-per-ton GHG abatement methods. Here, we estimate and map cost (US$ per tCO 2 ) for two common reforestation methods: natural regeneration plantations. We do so by producing integrating new maps of implementation costs opportunity reforestation, likely plantation genus carbon accumulation means plantations, accounting storage in harvested wood products. find (46%) plantations (54%) would each have lower across about half the area considered suitable 138 low- middle-income countries. Using more cost-effective method at location, 30 year, time-discounted potential below US$50 is 31.4 GtCO (24.2–34.3 US$20–100 )—44% than alone or 39% alone. that offers 10.3 (2.8) times US$20 (US$50 most recent IPCC estimate.

Forest disturbance decreased in China from 1986 to 2020 despite regional variations

Abstract Human activities have altered disturbance patterns in many parts of world, but there is no quantitative information on and trends forest regimes China. We applied a spectral-temporal segmentation approach over all available Landsat data to map individual patches characterize the rate, size, frequency, severity across China’s forests. From 1986 2020, about 39.7% forests were disturbed with an annual rate 1.16 ± 0.41% yr −1 . The decreased at −390 142 km 2 , primarily driven by effective implementation protection policy since 2000s. size generally intensified Southeast, weakened Northeast Our high-quality, spatially explicit provides essential layer understand landscape-scale drivers dynamics functions for important less understood pan-temperate regions.

Substantial and increasing global losses of timber-producing forest due to wildfires

Nature Geoscience, Journal Year: 2023, Volume and Issue: 16(12), P. 1145 - 1150

Published: Nov. 13, 2023

Abstract One-third of global forest is harvested for timber, generating ~US$1.5 trillion annually. High-severity wildfires threaten this timber production. Here we combine maps logging activity and stand-replacing to assess how much timber-producing has been lost wildfire century, quantify spatio-temporal changes in annual area lost. Between 2001 2021, 18.5–24.7 million hectares forest—an the size Great Britain—experienced wildfires, with extensive burning western USA Canada, Siberian Russia, Brazil Australia. Annual burned increased significantly throughout twenty-first pointing substantial wildfire-driven losses under increasingly severe climate change. To meet future demand, producers must adopt new management strategies emerging technologies combat increasing threat wildfires.

Past decade above-ground biomass change comparisons from four multi-temporal global maps

International Journal of Applied Earth Observation and Geoinformation, Journal Year: 2023, Volume and Issue: 118, P. 103274 - 103274

Published: April 1, 2023

Above-ground biomass (AGB) is considered an essential climate variable that underpins our knowledge and information about the role of forests in mitigating change. The availability satellite-based AGB change (ΔAGB) products has increased recent years. Here we assessed past decade net ΔAGB derived from four global multi-date maps: ESA-CCI maps, WRI-Flux model, JPL time series, SMOS-LVOD series. Our assessments explore use different reference data sources with re-measurements within decade. comprise National Forest Inventory (NFI) plot data, local maps airborne LiDAR, selected Resource Assessment country countries well-developed monitoring capacities. Map to comparisons were performed at levels ranging 100 m 25 km spatial scale. revealed LiDAR compared most reasonably while using NFI only showed some agreements aggregation <10 km. Regardless level, losses gains according map consistently smaller than data. Map-map highlighted captured known deforestation hotspots. also identified several carbon sink regions detected by all maps.

Biodiversity Impact Assessment Considering Land Use Intensities and Fragmentation

Environmental Science & Technology, Journal Year: 2023, Volume and Issue: 57(48), P. 19612 - 19623

Land use is a major threat to terrestrial biodiversity. Life cycle assessment tool that can assess such threats and thereby support environmental decision-making. Within the Global Guidance for Cycle Impact Assessment (GLAM) project, Initiative hosted by UN Environment aims create life impact method across multiple categories, including land impacts on ecosystem quality represented regional global species richness. A working group of GLAM project focused developed new characterization factors combine strengths two separate recent advancements in field: consideration intensities fragmentation. The data sets parametrize underlying model are also updated from previous models. cover five groups (plants, amphibians, birds, mammals, reptiles) broad types (cropland, pasture, plantations, managed forests, urban land) at three intensity levels (minimal, light, intense). They available level ecoregions countries. This paper documents development factors, provides practical guidance their use, critically assesses remaining shortcomings.
