Brochure, flyer, fact-sheetUnderstanding countries’ status and challenges for the estimation of carbon stock changes from mineral soils in national greenhouse gas inventories: Preliminary survey findings 2022
Also available in:
No results found.Despite the growing global support for capacity building to improve soil management, the estimation and reporting of greenhouse gas (GHG) emissions and removals, especially from mineral soils in national GHG inventories, is still very limited. In 2021, the Institute for Global Environmental Strategies (IGES) and FAO conducted a global survey to assess how countries have addressed the estimation of carbon stock changes (CSCs) in mineral soils in their GHG inventories. This report presents the findings from the survey. -
Book (stand-alone)Measuring and modelling soil carbon stocks and stock changes in livestock production systems – A scoping analysis for the LEAP work stream on soil carbon stock changes 2019
Also available in:
No results found.In order to build consensus on methods to measure and model soil carbon stocks and stock changes, the Steering Committee of the Livestock Environmental Assessment and Performance (LEAP) Partnership mandated a task force to develop this scoping analysis and pave the way towards the formation of the LEAP Tecnical Advisory Group on soil carbon stock changes. Soil carbon sequestration and storage in grasslands offers a significant potential to compensate for GHG emissions from livestock, but the lack of consensus on the appropriate methodologies to account for soil carbon stock changes hinders robust and standardized assessments. In this report, we reviewed several published soil organic carbon (SOC) models, and evaluated their aptitude to combine them with life cycle assessments (LCAs). Among contentious issues, the most relevant are: a) the lack of universal models, b) the uneven data availability, comparability and quality between countries and regions, and c) the difficulty to match measurable SOC fractions with those determined by the models. Taking this into account, a tiered approach is proposed, according to the availability of original data to run the models. The use of IPCC carbon (C) accounting system appears to be the simplest approach suitable to countries with scarcity of original C data. Conversely, more complex models such as Century (Parton 1987, 1988) or Roth C (Smith 1998) are likely to perform better and give less uncertainty when original input data are easily available. -
