The Global Soil Organic Carbon Map (GSOCmap)

The first ever Global Soil Organic Carbon map (GSOCmap) will be launched on World Soil Day 2017!

The GSOC map is not just a map! It is also a comprehensive process that supports the development and empowerment of national capacities to build their national soil information systems.

SOIL ORGANIC CARBON

Soil organic carbon (SOC) forms the basis of soil health, fertility, and food production. A healthy soil with an ideal amount of SOC (the main component of soil organic matter) can provide optimal plant growing conditions, functional nutrient cycling and effective water infiltration and storage. Agricultural soils are among the planet's largest reservoirs of carbon and hold potential for expanded carbon sequestration, and thus provide a prospective way of mitigating the increasing atmospheric concentration of carbon dioxide.

GSOCmap

Since SOC is highly dynamic we need to know how much SOC is stored in our soils and monitor changes around the world, especially in vulnerable hotspots. While remote sensing technology, particularly satellite imagery, have played a key role in providing land cover datasets, the quantity and quality of SOC is typically more difficult to map and in many cases cannot be remotely sensed. Large discrepancies have been noted between different available products and worldwide, data, need to be harmonized. In-situ or ground-based data and high resolution imagery are thus an important requirement for producing accurate SOC datasets. More

DIGITAL SOIL MAPPING TRAININGS

The GSP and the ITPS launched a global endeavor to develop the GSOCmap using a country-driven approach as part of the Global Soil Information System (GLOSIS). GSP provides technical support and on-the-job training to most countries to produce national SOC maps according to standardized specifications. Send an email for more information.
