Unlocking the potential of soil organic carbon - Ronald Vargas

  1. 1. Unlocking the potential of soil organic carbon Ronald Vargas
  2. 2. Sustainable Development Goals
  3. 3. What to promote in terms of SOC? • Consistent with our approach, ITPS suggested the organization of a Global Symposium on SOC together with other organizations. • Bringing scientific evidence for policy making. • For positioning soils and SOC in the decision making agenda. • Setting a way forward where we can foster feasible options.
  4. 4. Milestone event: First time that a scientific symposium of this nature is co-organized by different organizations and bodies of the United Nations to gather scientific evidence for policy development on the role of SOC for climate change, food security and SDGs agendas. Global Symposium on Soil Organic Carbon
  5. 5. • 8 recommendations paving the way forward for the global SOC work. Through the development of policies and implementation of actions to foster the protection, sequestration, measurement, mapping, monitoring and reporting of SOC. • Partners are currently working on the implementation of the Outcome Document and specific recommendations.
  6. 6. SOC: sequestering more? - Efforts should be made to at least MAINTAIN current SOC stocks (by reducing degradation). - Ideally, we should foster SOC Sequestration through proven and locally contextualized practices, WHEREVER IS SCIENTIFICALLY SUITABLE (not all soils). - Innovation is crucial for this, but we should be innovative in sound practices, no renaming or creating new concepts only.
  7. 7. Recommendations : MEASURING, MAPPING, MONITORING AND REPORTING SOC STOCKS AND STOCK CHANGES 1. Organize capacity development and training for countries to develop national reference values for SOC stocks, as well as the necessary data management capacities and facilities. 2. Establish a working group to develop feasible and regionally contextualized guidelines for measuring, mapping, monitoring and reporting on SOC that can be adapted locally to monitor SOC stocks and stock changes to support management decisions.
  8. 8. Recommendations : FOSTERING SOC SEQUESTRATION 3. In estimates of the potential for SOC sequestration, include the full GHG balance and consider possible interactions between the carbon and nitrogen cycles that could affect the climate change mitigation potential of applied practices. 4. The design of implementation strategies and appropriate soil and land management practices for SOC protection and sequestration should consider land use and the local environmental, socio-economic, cultural and institutional contexts, and potential barriers to adoption. 5. Identify and specify the tangible short-term and long-term benefits for farmers of management practices for SOC sequestration to trigger their adoption, and introduce mechanisms to incentivize the adoption of such practices.
  9. 9. Recommendations : MANAGING SOC IN SOILS WITH HIGH SOC (PEATLANDS, PERMAFROST AND BLACK SOILS) 6. Prevent SOC losses by maintaining current SOC stocks (especially in carbon-rich soils) as the minimum action on SOC management. 7. Prioritize sustainable management actions on soils with the highest carbon stocks in the development of national and regional policies on soil conservation to prevent SOC losses. 8. Support land-users sufficiently to implement and sustain appropriate soil and land management practices to protect and enhance SOC under local conditions for long-term benefit.
  10. 10. Recommendation 1: Organize capacity development and training for countries to develop national reference values for SOC stocks, as well as the necessary data management capacities and facilities. • 150 experts from 110 countries covering 60% of the world area. SOC mapping
  11. 11. Recommendation 2: Establish a working group to develop feasible and regionally contextualized guidelines for measuring, mapping, monitoring and reporting on SOC that can be adapted locally to monitor SOC stocks and stock changes to support management decisions. • 135 experts from all GSP Regions responded to the Call !WE ARE HERE!
  12. 12. Recommendation 3: In estimates of the potential for SOC sequestration, include the full GHG balance and consider possible interactions between the carbon and nitrogen cycles that could affect the climate change mitigation potential of applied practices. Recommendation 4: The design of implementation strategies and appropriate soil and land management practices for SOC protection and sequestration should consider land use and the local environmental, socio-economic, cultural and institutional contexts, and potential barriers to adoption. Recommendation 5: Identify and specify the tangible short-term and long-term benefits for farmers of management practices for SOC sequestration to trigger their adoption, and introduce mechanisms to incentivize the adoption of such practices.
  13. 13. The VGSSM is generally compatible with the SM of SOC. It is general in nature, however should be refined at the national and local scales to encompass site-specific condition: • Climate • Soil type • Land use and • Farm typology
  14. 14. • 220 people answered the call • 80 replied to the online questionnaire • 130 actively participating • Online participation and collaboration • Formal format with the editorial rules • Google docs for editing and correcting Working group to produce a technical manual on SOC management at the regional and sub-regional scale
  15. 15. Synthesis of the process for generating the structure of the technical manual on SOC management Regional Soil Partnerships Global ecological zones LADA Global Map of Land Use Systems Synthesis: LADA Global Map of LUS Call for the establishment of a WG and definition of the structure of the manual Online survey filling and sending resultsDefinition of the timelineReview by ITPS and other stakeholders LAUNCH OF THE TECHNICAL MANUAL ON SOC MANAGEMENT
  16. 16. Structure of the technical manual on SOC management 3. Recommended management practices and actions for preservation and/or enhancement of SOC 1. Unmanaged and Protected Lands (including virgin forests, rangelands, grassland, shrublands, 2. Forestry (managed/silviculture). 3. Forestry with agricultural or livestock activities: agroforestry, silvopastoral systems. 4. Grassland, shrublands, and bare and sparse areas with low, moderate, and high livestock density. 5. Rainfed agriculture - subsistence and familiar. 6. Rainfed agriculture – commercial. 7. Irrigated agriculture. 8. Rainfed or irrigated agriculture with livestock. 9. Urban areas. 10. Wetlands with agricultural activities.

  18. 18. Recommendation 6: Prevent SOC losses by maintaining current SOC stocks (especially in carbon-rich soils) as the minimum action on SOC management. Recommendation 7: Prioritize soils with the highest carbon stocks in the development of national and regional policies on soil conservation to prevent SOC losses. Recommendation 8: Support land-users sufficiently to implement and sustain appropriate soil and land management practices to protect and enhance SOC under local conditions for long-term benefit.
  19. 19. International Network on Black Soils • To provide a platform for countries with BS to discuss common issues related to the conservation and SM of BS. • To develop a report on the global status. • To foster collaboration among countries. • To identify relevant research gaps. • To develop governance guidelines. International Symposium on Black Soils • State the status of black soil resources. • Promote sustainable use and management of black soils. • Build Concept Note and Framework of INBS. • Initiate work plans and projects of INBS. • Organize a outcome document and a global status report on black soils.
  20. 20. Koronivia: capitalizing on the expertise captured under the GSP process Improved soil carbon, soil health and soil fertility under grassland and cropland as well as integrated systems, including water management.
  21. 21. What's Next? • Interpretation of GSOC map. • Global SOC Monitoring System based on the GSOCmap. • Potential of carbon sequestration of global soils.
