Book (stand-alone)Technical bookMeasuring 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. -

Book (stand-alone)High-profileStatus of the World's Soil Resources: Main Report 2015
Also available in:
No results found.The SWSR is a reference document on the status of global soil resources that provides regional assessments of soil change. The information is based on peer-reviewed scientific literature, complemented with expert knowledge and project outputs. It provides a description and a ranking of ten major soil threats that endanger ecosystem functions, goods and services globally and in each region separately. Additionally, it describes direct and indirect pressures on soils and ways and means to combat s oil degradation. The report contains a Synthesis report for policy makers that summarizes its findings, conclusions and recommendations.The full report has been divided into sections and individual chapters for ease of downloading:

Book (stand-alone)High-profileState of knowledge of soil biodiversity - Status, challenges and potentialities
Report 2020
2020Also available in:
No results found.There is increasing attention to the importance of biodiversity for food security and nutrition, especially above-ground biodiversity such as plants and animals. However, less attention is being paid to the biodiversity beneath our feet, soil biodiversity, which drives many processes that produce food or purify soil and water. This report is the result of an inclusive process involving more than 300 scientists from around the world under the auspices of the FAO’s Global Soil Partnership and its Intergovernmental Technical Panel on Soils, the Convention on Biological Diversity, the Global Soil Biodiversity Initiative, and the European Commission. It presents concisely the state of knowledge on soil biodiversity, the threats to it, and the solutions that soil biodiversity can provide to problems in different fields. It also represents a valuable contribution to raising awareness of the importance of soil biodiversity and highlighting its role in finding solutions to today's global threats. -
Book (series)Technical reportRespecting free, prior and informed consent
Practical guidance for governments, companies, NGOs, indigenous peoples and local communities in relation to land acquisition
2014Improving governance of tenure is the objective of the Voluntary Guidelines on the Responsible Governance of Tenure of Land, Fisheries and Forests in the Context of National Food Security (Guidelines), which serve as a reference and set out principles and internationally accepted standards for responsible practices. The Guidelines state that responsible investments should do no harm, safeguard against dispossession of legitimate tenure right holders and environmental damage, and should respect human rights. This technical guide on Respecting free, prior and informed consent (FPIC) sets out practical actions for government agencies to respect and protect FPIC and for civil society organizations, land users and private investors globally to comply with their responsibilities in relation to FPIC, as endorsed by the Guidelines.
