Book Description
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 Description
This publication contains a methodology and software tools for assessing carbon stocks and modelling scenarios of carbon sequestration developed and tested in pilot field studies in Mexico and Cuba. The models and tools enable the analysis of land use change scenarios in order to identify in a given area (watershed or district) land use alternatives and land management practices that can both maximise food production, soil carbon sequestration and biodiversity and minimize land degradation. The aims is to develop and implement "win-win" options that satisfy the multiple goals of farmers, land users and other stakeholders in relation to food security, carbon sequestration, biodiversity and land conservation. The publication also contains a CD-ROM including three case studies and a Soil-C program demo, program and user manual.

Book Description
Greenhouse gas emissions by the livestock sector could be cut by as much as 30 percent through the wider use of existing best practices and technologies. FAO conducted a detailed analysis of GHG emissions at multiple stages of various livestock supply chains, including the production and transport of animal feed, on-farm energy use, emissions from animal digestion and manure decay, as well as the post-slaughter transport, refrigeration and packaging of animal products. This report represents the most comprehensive estimate made to-date of livestocks contribution to global warming as well as the sectors potential to help tackle the problem. This publication is aimed at professionals in food and agriculture as well as policy makers.

Book Description
This document provides a conceptual framework and standard methodologies for the monitoring, reporting and verification of changes in SOC stocks and GHG emissions/removals from agricultural projects that adopt sustainable soil management practices (SSM) at farm level. It is intended to be applied in different agricultural lands, including annual and perennial crops (food, fibre, forage and bioenergy crops), paddy rice, grazing lands with livestock including pastures, grasslands, rangelands, shrublands, silvopasture and agroforestry. Although developed for projects carried out at farm level, potential users include investors, research institutions, government agencies, consultants, agricultural companies, NGOs, individual farmers or farmer associations, supply chain and other users who are interested in measuring and estimating SOC stocks and changes and GHG emissions in response to management practices. The document is an outcome of the successful Global Symposium on Soil Organic Carbon (GSOC17), which was held in Rome in March 2017. The document is of technical nature in support of the Soil organic carbon (SOC) sequestration work. Its use is not mandatory but of voluntary nature.

Book Description
Since carbon sequestration in soils reduces the amount of carbon available to the atmosphere, the Kyoto Protocols have heightened interest in soil carbon pools and their effect on carbon fluxes. Assessment Methods for Soil Carbon addresses many of the questions related to the measurement, monitoring, and verification of organic and inorganic carbon in soils. The major topics covered are: carbon pools; soil sampling and preparation, analytical techniques for soil carbon; soil erosion and sedimentation; remote sensing, GIS and modeling; procedures for scaling carbon data from point and local measurements to regional and even national scales; and economic and policy issues. In Assessment Methods for Soil Carbon, leading researchers show that we now have the ability to measure, monitor, and verify changes to soil carbon. The book establishes the need for standardized methods that can be used by anyone, and helps us better understand the link between the pedosphere (soils) and the atmosphere. It also shows the importance of developing links between the economics of carbon sequestration and the amounts sequestered, and highlights the need for scientists and policy makers to interact to ensure that policies fit within the scope of present technologies.

Book Description
Monaro Farming Systems (MFS) is a regional landholder group initiated and developed in September 2007. The group was set up, primarily, as a knowledge- and information-based organisation, to help farm businesses to be more profitable and resilient in the long term. In this way it allows peers and researchers to work together to improve practice and innovation in farming systems. The group has over 100 individual members, from the Bombala, Cooma-Monaro and Snowy River Shires. These members manage approximately 30% of the privately held land on the Monaro region (over 80,000ha) and are responsible for approximately 40% of agricultural production. The Monaro soil carbon project aimed to demonstrate the impact of farm management strategies on the concentration and stock of carbon in soil over a two year period. Eight different land-use systems were identified by members of the Monaro Farming Systems group. The practices of interest included liming, nutrient management, introduced perennial pastures and minimum disturbance cropping. In addition the project looked at increases in biomass production within the context of reducing DSE emissions intensity and any offsets required for increases in stocking rates associated with production gains. Monaro Farming Systems members wanted to compare the influence of soil type, rainfall and land management on carbon stocks. The questions they wanted answered were: Does minimum disturbance cropping influence carbon stocks over a 2 year period? What is the effect of ‘parent material’ ie. shale, deep granite and basalt (ascending texture, fertility and structure) on carbon stocks in the Monaro region? What influence does ‘aspect’ have on carbon stocks in a system with optimum sequestration potential ie. fertilised, permanent, perennial pasture system? Does liming introduced pasture increase C sequestration? What effect does soil fertility have on C stocks in the Monaro region? What effect does pasture age have on the potential of a phalaris perennial pasture to sequester carbon. Does age create a ‘ceiling’ on sequestration potentials?
