The document describes the GSOCseq project, which aims to map the global soil organic carbon sequestration potential under different soil management scenarios through 2030. It will simulate carbon stocks in agricultural lands at national scales to identify areas with potential for increased carbon storage. The process involves countries running a modeling script using national climate, land use, and soil data to generate maps of carbon sequestration rates and soil organic carbon levels. Regional trainings and technical guidelines are provided to support countries' participation and capacity to produce their own maps as part of a global effort to understand soils' role in climate change mitigation.

- 2. GSOCseq- Global Soil Organic Carbon Sequestration Potential Map The GSOCseq is to fill a big gap, simulate soil organic carbon stocks over a 20–year period in agricultural lands and quantify the soil organic carbon sequestration potential under different sustainable soil management and business as usual (BAU) scenarios at national scale and eventually will give us a global perspective and understanding of critical role of soils in major global issues.
- 3. GSOCseq Approach Low carbon inputs sustainable soil management scenario SSM1 SOCseq SSM1 Medium carbon inputs sustainable soil management scenario SSM2 SOCseq SSM2 High carbon inputs sustainable soil management scenario SSM3 SOCseq SSM3 Business as usual BAU SOCseq BAU BAU scenario refers to the land use, land management, production practices or technologies that are currently being implemented in croplands and grazing lands.
- 4. GSOCseq- Global Soil Organic Carbon Sequestration Potential Map Entire process is country-driven, continuous, participatory, based on and guided by the best available science, rigorous collection and analysis of appropriate data, and consideration of experiences and good practices within, and outside, countries.
- 5. ● Set attainable and evidence based national targets for carbon sequestration; ● Achieve their commitments to the LDN Target Setting Programme implemented by the UNCCD; ● Simulate national soil organic carbon stocks under Business as Usual (BAU) and different sustainable soil management scenarios; ● Identify which regions, soil types and production systems have greater risks of decreasing and which with greater potential to increase SOC stocks, in order to establish priorities for research and implementation of public policies; GSOCseq - ADDED VALUE & BENEFITS ● Support policy making in adoption of SSM practices that foster SOC sequestration at national scale; ● Improve technical capacities on sustainable soil management, soil data management, digital soil mapping and modelling. ● Improve soil health as an integral step towards achieving the Sustainable Development Goals (SDGs), specifically the Goals on zero hunger (SDG 2), climate action (SDG 13), and life on land (SDG 15). ● Support the provision of incentives to farmers implementing SOC-centred SSM practices
