GSOCseq - Relative soil organic carbon sequestration rates

The Relative SOC sequestration rates are accompanied by their corresponding uncertainty maps (%). Uncertainties in GSOCseq v1.1 were estimated by forward propagation of plausible uncertainty ranges of input layers (see the Technical Report, Section 5.6), and do not include the model structural uncertainties. The uncertainties maps include: SSM1: uncertainty of relative sequestration rates under sustainable soil management scenario 1 This map represents the uncertainties (in percent) in the estimate of the average annual rate of soil organic carbon stock change after 20 years of implementation of sustainable soil management practices (Scenario 1) compared to business as usual practices, due to the uncertainties of the input layers. SSM2: uncertainty of relative sequestration rates under sustainable soil management scenario 2 This map represents the uncertainties (in percent) in the estimate of the average annual rate of soil organic carbon stock change after 20 years of implementation of sustainable soil management practices (Scenario 2) compared to business as usual practices, due to the uncertainties of the input layers. SSM3: uncertainty of relative sequestration rates under sustainable soil management scenario 3 This map represents the uncertainties (in percent) in the estimate of the average annual rate of soil organic carbon stock change after 20 years of implementation of sustainable soil management practices (Scenario 3) compared to business as usual practices, due to the uncertainties of the input layers. **Contact points:** **Data lineage:** Data quality information not available **Online resources:** Download the data from Google Cloud Storage

GSOCseq is a country-driven global product which depicts the projected Soil Organic Carbon (SOC) stocks (in t C ha-1) 20 years into the future, in current agricultural lands under different soil management scenarios that vary in the degree of carbon inputs to the soil, at 0-30 depth and 1 x 1 km spatial resolution. __Initial SOC stocks (GSOCseq_T0_Map030)__ This map represents an estimate of current soil organic carbon stocks (in t C ha-1) in 2020 (stocks at time 0; t0), at a soil depth of 0-30 cm. The best available national datasets collected over the years from the different countries were used to derive the 2020 baseline stocks __Final SOC stocks under business as usual scenario(GSOCseq_finalSOC_BAU_Map030)__ This map represents the projected soil organic carbon stocks (in t C ha-1) in 2040 (t20), after 20 years of business as usual (BAU) management, at a soil depth of 0-30 cm. __Final SOC stocks under sustainable soil management scenario 1 (GSOCseq_finalSOC_SSM1_Map030)__ This map represents the projected soil organic carbon stocks (in t C ha-1) in 2040, after 20 years of implementation of sustainable soil management (SSM) practices that generate a 5 percent increase in carbon inputs (SSM Scenario 1), at a soil depth of 0-30 cm. __Final SOC stocks under sustainable soil management scenario 2 (GSOCseq_finalSOC_SSM2_Map030)__ This map represents the projected soil organic carbon stocks (in t C ha-1) in 2040, after 20 years of implementation of sustainable soil management (SSM) practices that generate a 10 percent increase in carbon inputs (Scenario 2), at a soil depth of 0-30 cm. __Final SOC stocks under sustainable soil management scenario 3 (GSOCseq_finalSOC_SSM3_Map030)__ This map represents the projected soil organic carbon stocks (in t C ha-1) in 2040, after 20 years of implementation of sustainable soil management (SSM) practices that generate a 20 percent increase in carbon inputs (Scenario 3), at a soil depth of 0-30 centimeters. **Contact points:** **Data lineage:** Data quality information not available **Online resources:** Download the data from Google Cloud Storage

__GSOCseq - SOC Stocks Uncertainties__ The Initial SOC stocks (stocks at time 0, t0) and the final SOC stocks under the BAU and three SSM scenarios are accompanied by three uncertainty maps. Uncertainties in GSOCseq v1.1 represent the forward propagation of plausible uncertainty ranges of input layers (see the Technical Report, Section 5.6). These uncertainties do not include the model structural uncertainties. The uncertainties maps of the SOC stocks include the following products: T0: uncertainty of initial SOC stocks (stocks at time 0; T0).The uncertainties (in percent) in the estimate of initial soil organic carbon stocks in 2020, due to the uncertainties of the input layers. BAU: uncertainty of final SOC stocks under business as usual scenario. The uncertainties (in percent) in the estimate of the projected soil organic carbon stocks after 20 years of business as usual (BAU) management, due to the uncertainties of the input layers. SSM: uncertainty of final SOC stocks under sustainable soil management scenarios This map represents the uncertainties (in percent) in the estimate of the projected soil organic carbon stocks after 20 years of sustainable soil management practices, due to the uncertainties of the input layers **Contact points:** **Data lineage:** Data quality information not available **Online resources:** Download the data from Google Cloud Storage

Global Soil Organic Carbon Map v1.5 is the first global soil organic carbon map ever produced through a consultative and participatory process involving member countries, which makes this map totally new and unique. In fact, the map was prepared by member countries, under the guidance of the Intergovernmental Technical Panel on Soils and the Global Soil Partnership Secretariat. Countries agreed on the methodology to produce the map and were trained on modern tools and methodologies to develop national maps. The Global Soil Partnership then gathered all national maps to produce the final product, ensuring a thorough harmonization process. The dataset comes along with a technical report presenting methodologies and process of compiling the Global Soil organic Carbon Map. The link to download the report is available in the on-line resources. **Data revision:** 2019-06-01 **Supplemental Information:** No data value : -3 Unit : t/ha Scale Factor : 1.0 Map code : GSOCMAP1-5-0 **Contact points:** Resource Contact: [Yusuf Yigini](mailto:GSP-Secretariat@fao.org) Metadata Contact: [CBL Global Soil Partnership](mailto:GSP-Secretariat@fao.org) **Data lineage:** Information on data quality at https://openknowledge.fao.org/server/api/core/bitstreams/c3ccec0d-fe75-49b7-9a4c-ee0a8777fed9/content **Resource constraints:** This work is made available under the Creative Commons Attribution 4.0 International licence (CC-BY-4.0) **Online resources:** Download the data from Google Cloud Storage Download - GSOC-Map Technical Report Global Soil Partnership GSOCmap Contributors

These datasets were prepared within the scope of the CUP4SOIL (Copernicus user uptake for soil information products) project (Copernicus user update project). The soil property maps were generated at a resolution of 20m, and created with LUCAS and other continental level data using digital soil mapping. Users should assess the local predictive accuracy of the maps prior to using them for making recommendations at local (or field) level. The datasets contain the following soil properties (for top soil (0-30 cm) depth): Soil organic carbon content, pH in water, Total nitrogen, Bulk density (oven dry), Coarse fragments (volumetric), Soil inorganic carbon content, Sand, Silt, Clay. The SoilSuite products (https://c.geoservice.dlr.de/web/datasets/soilsuite_eur_5y) were used as covariates, together with a range of other copernics products. Measurement units and web links for the above properties can be found here below. The maps are provided as Web Map Service (WMS) layers which load dynamically in a GIS software. The Soil organic carbon content "soc_topsoil_030cm_mean_forest" layer is represented here in the Web Map Service (WMS). For more information and to visualize all layers, please refer to the ISRIC web page at https://maps.isric.org/. The suffix `_mosaic` refers to the full data (20m spatial resolution). If you need to use the data, please use layers with the `_mosaic` suffux. The suffix `_overviews` refers to spatial overviews for faster visualisation. However datasets with the `_overview` suffix will not load to the full resolution. **Data creation:** 2025-04-16 **Data publication:** 2025-04-16 **Contact points:** Metadata Contact: [Data infodesk](mailto:data@isric.org) Resource Contact: [Betony Colman](mailto:betony.colman@isric.org) Resource Contact: [Laura Poggio](mailto:laura.poggio@isric.org) Resource Contact: [Luis Calisto](mailto:luis.callisto@isric.org) Resource Contact: [Niels Batjes](mailto:niels.batjes@isric.org) **Data lineage:** Data quality information not available **Resource constraints:** Attribution 4.0 International (CC BY 4.0), https://creativecommons.org/licenses/by/4.0/ **Online resources:**
