GSOCmap - Yusuf Yigini, Guillermo Olmedo

  1. 1. GSOCmap Y. Yigini, G.F. Olmedo
  2. 2. What do we know about SOC? Soil organic carbon (SOC) represents the largest carbon (C) pool contained in terrestrial ecosystems
  3. 3. What do we know about SOC? Several efforts have been made to precisely quantify this global SOC pool. Available estimates report values between 504 and 1267 Pg of topsoil (0-30cm) SOC.
  4. 4. What do we know about SOC? There is a pressing need for the Earth system modeling community in order to improve our understanding of feedbacks between global C cycling and climate change. With this information we can make evidence-based decisions to mitigate and adapt to climate change and to boost sustainable agricultural production.
  5. 5. ▪ The GSP 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?

  20. 20. Country Submissions: 75 countries which represent 68% of world area have contributed their data to the GSOCmap before its public release on 5th December 2017. GSP Gap Filling: For the countries which were unable to contribute within the timeframe, GSP Secretariat created the maps using publically available soil data.

  25. 25. Validation • We ran a comparison with available data • The final database contains 312122 soil observations • Three different subsets were prepared from the full database. One including all the soil samples (’all data’), a second one only including samples with less than 150 Mg · ha, (’mineral soils’), and the last one including samples with more than 150 Mg · ha, (’carbon-rich soils’).

  30. 30. Versioning • The GSOCmap is a living product and is being updated as soon as more and better information is available (current version 1.2.0). • The GSP uses semantic versioning at certain level so that there is a standard pattern to data releases. • Semantic versioning is widely used in the software development world and helps developers having a standardized way of versioning software releases. • It follows the format of MAJOR.MINOR.PATCH - 1.2.0
