ITEM 11. Soil Organic Carbon Working Groups - Yusuf Yigini, Rosa Cuevas

  1. 1. Technical Manual on SOC management Ms. Rosa Cuevas
  2. 2. Historic trends in soil carbon stocks Magnitude of SOC loss since 1850: • 47 to 104 Pg for different biomes • 66 to 90 Pg for major soils Status of the World's Soil Resources
  3. 3. Estimates of the historic C loss are useful as a reference point for assessing the technical potential of C resequestration in soil. The rate of SOC sequestration with adoption of recommended technologies depends on: • Soil texture and structure • Rainfall • Temperature • Farming system • Soil management Lal, 2016
  4. 4. • Priority action should be to stabilize and/or increase the global SOM stocks (e.g. SOC and soil organisms). • Each nation should identify locally appropriate SOC-improving management practices and facilitate their implementation. Status of the World's Soil Resources
  5. 5. Mulching Cover cropping Integrated Nutrient Management Rhizobium Complex farming systems No-till Sustainable management Lal, 2017
  6. 6. 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.
  7. 7. Technical manual on SOC management at the regional and sub-regional scale • This WG represented a response to the urgent need to identify and compile management practices and LUS that promote the preservation and/or enhancement of SOC stocks. “Promote sustainable management of soil resources for soil protection, conservation and sustainable productivity”
  8. 8. 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. Structure of the technical manual on SOC management
  9. 9. • Description of the practice: Region and/or country where the practice can be applied, measurements and evidence-based results with the adequate statistical accuracy (include data from meta-analysis). • Context: Local environmental, socio-economic, cultural and institutional contexts. • Trade-offs: Possible synergies and co-benefits or conflicts with other practices. • Potential barriers to adoption: Considerations for adoption within the cultural and socio-economic context. Possible side effects that could negatively affect the climate change mitigation potential of the practice. • Benefits and management recommendations: Soil processes that enable SOC preservation and/or increase, case studies and success stories of effective practice adoption and achieved SOC/SOM preservation/increase. • Potential of C sequestration: For the recommended management practices, including the possible trade-offs of SOC sequestration efforts when assessing the full GHG balance.
