➢ First test round of the Global Soil Information System following a
bottom-up approach.

4. Role of Soil Organic Carbon (SOC)
Critical functions

5. Soil Organic Carbon Data

6. ▪ The GSP is currently tasked to provide support on soil carbon
issues
▪ Request from the SPI-UNCCD to ITPS to prepare a Global Soil
Organic Carbon map as a contribution to the SDG indicator
15.3.1.
▪ It’s part of the ongoing activities to establish the Global Soil
Information System under the Pillar 4.
▪ Need to empower member countries to develop their own
national soil information using state of the art techniques.
▪ It’s crucial to make a SOC Baseline available considering the
dynamic nature of soils.
Why GSOCmap?

8. According to the data recorded in the HWSD the total SOC stock were computed
separately for the topsoil layer (0 - 30cm) and the subsoil layers (30 - 100cm). Where
the soil depth was less than 100cm stocks were computed to that depth. The SOC
stocks thus computed for the two layers were then combined to provide an estimate of
SOC stock in t ha-1 to a nominal depth of 1m
R. Hiederer, M. Köchy 2012

9. UNEP-WCMC updated Global Carbon Map
The updated global carbon map improves upon the rather coarse data on soil carbon (IGBP-DIS 2000) that were
used in UNEP’s Carbon and biodiversity: a demonstration atlas (Kapos et al. 2008). A global map of estimated
soil carbon stocks to 1m depth was generated based on the soil organic carbon and bulk density values
included in the HWSD (FAO/IIASA/ISRIC/ISS-CAS/JRC 2009). The data in the HWSD were adjusted and
missing data filled in where possible. It therefore provides a better tool for visualising the distribution of carbon
stocks, which are dominated by soil stocks in some parts of the world such as boreal peatlands and tropical
swamps.

11. A system for automated soil mapping based on global
compilation of soil profile data and publicly available
remote sensing data.
SoilGrids is a system for automated soil mapping based
on state-of-the-art spatial predictions methods. SoilGrids
predictions are based on globally fitted models using soil
profile and environmental covariate data. Currently,
SoilGrids.org serves a collection of updatable soil
property and class maps of the world at 1 km / 250 m
spatial resolutions produced using automated soil
mapping based on machine learning algorithms.

14. SoilGrids data (GeoTiffs) can be obtained either via the
web-mapping interface at www.soilgrids.org, via FTP.
To download the complete global maps please use the
FTP service:
ftp.soilgrids.org - FTP Service (Global GeoTiffs)
SoilGrids.org — Web Service (GeoTiff Tiles)

16. NATIONAL EFFORTS
Many recent national and regional SOC maps were developed; (at least 70
publications from 50 countries), with improved national data bases and upscaling
models
Poland 50,000 samples
Slovakia 16,636 soil profiles
Denmark 45,000 samples

17. ● Precise and reliable global view on soil organic carbon (SOC) is
needed under different UN conventions and related processes
● Soil carbon is key indicator related to water and nutrient
dynamics of soils, its decomposer activity, and the physical soil
structure/stability.
● A combination of reliable national SOC estimates around the
globe can provide a new baseline on the currently existing SOC
density.

18. ● Country-driven approach
● Generate SOC soil grids : use existing soil profile data and soil
(polygon) maps, combined with digital soil mapping
● Build on existing national capacities and extend these
● Develop first indicator for the Global Soil Information
System (GSIS) - GSP demonstration project

37. Roadmap: ...provides definitions and
specifications for the GSOCMap
products.
This document provides background
and detailed specifications about the
required data sources and
methodologies.
The specifications were jointly
prepared with International Network
of Soil information Institutions .
GSOCmap - Technical Specifications

38. Roadmap:
... provides
• generic methodologies and the technical
steps to produce a SOC map.
• step-by-step guidance from data
preparation to developing 1 km grids for
SOC stocks.
• the compilation and pre-processing of
auxiliary spatial data sets, upscaling
methodologies, and uncertainty assessments.
Guidance is mainly specific to soil carbon data,
but also contains many generic sections on soil
grid development due to its relevance for other
soil properties.
