Book (series)Mitigation of greenhouse gas emissions in livestock production – A review of technical options for non-CO2 emissions 2013
Also available in:
Animal agriculture substantially contributes to the world economy by providing food, jobs, and financial security for billions of people. With increasing concerns over global climate change and pollution, efforts are underway to reduce the overall environmental impact of animal production. This document analyses emission of non-carbon dioxide greenhouse gases, an important segment of the environmental footprint of animal production. It has been developed by a team that included experts in animal /ruminant nutrition, manure and soil management, animal and whole-farm modeling, and animal reproduction. Over 900 publications focusing on nutritional and manure management mitigation strategies for methane (enteric or from manure) and nitrous oxide emissions were reviewed and analysed, and a synthesis of feed-, animal management- and manure management-based mitigation approaches and interactions amongst them has been presented. This document will help researchers, animal industry consultants, policy-makers, animal producers, non-governmental organizations, and other groups with interest in maintaining a viable and environmentally-responsible animal production sector to make sound decisions on selection and adoption of effective and economically feasible greenhouse gas mitigation practices. -
Book (series)Nitrogen inputs to agricultural soils from livestock manure. New Statistics 2018
Also available in:
No results found.The global agricultural sector today faces the double challenge of feeding a growing population while preserving the underlying natural resources of land, water and air. In the meantime, already a third of the world’s soils are degraded. Soil and nutrient management techniques aimed at restoring soil health will therefore be essential to meeting these challenges. Livestock manure is a source of nitrogen and other plant nutrients when applied to soils. It is also high in organic matter and can help address soil deficiencies and improve soil quality. However, inappropriate manure management can have detrimental effects on the environment due to pollution from losses of excess nutrients to waterways and the atmosphere. This report sheds light on the amount of nitrogen applied to agricultural soils from livestock manure at different scales, and on the relevance of producing, refining and monitoring statistics on livestock manure for environmental and agronomic policy and planning. The report presents the relevant statistics available at FAO to this end, and demonstrates how they can be used for a nutrient input analysis at a national, regional and global level. The data include FAOSTAT chemical and mineral fertilizers statistics integrated with estimates of livestock manure from the FAOSTAT and the Global Livestock Environmental Assessment Model. This report is intended for use by various audiences, including agricultural statistics services or agencies in relevant line ministries, academia, industry and the general public in member countries, and provides country-level reference statistics using internationally-recognized and transparent methodologies. -
Book (stand-alone)Estimating Greenhouse Gas Emissions in Agriculture
A Manual to Address Data Requirements for Developing Countries
2015Countries report their greenhouse gas (GHG) emissions and removals from all sectors via national GHG Inventories, submitted to the United Nations Framework Convention on Climate Change (UNFCCC) in accordance with international climate policy agreements and technical guidelines developed by the Intergovernmental Panel on Climate Change (IPCC). The agriculture sector represents a unique challenge for national inventory compilers, especially in developing countries, due to significant difficulties in compiling and regularly updating national statistics for agriculture, forestry and land use —the first necessary step in preparing national GHG estimates. This Manual provides Member Countries with a tool and methodology to help identify, build and access he minimum set of activity data needed for GHG estimation. Required data is largely drawn from country’s official national agricultural and forestry statistics, as disseminated in FAO’s corporate database FAOSTAT, and integrated by geo-spati al data obtained from recognized international sources. Users are provided with step-by-step guidance on how to use this minimum set to build a default, yet complete national GHG emission dataset for agriculture and land use, which follows the default, Tier 1 approach of the Intergovernmental Panel on Climate Change (IPCC) Guidelines on National GHG Inventories. This Manual therefore contributes to FAO and the Global Strategy support to national processes towards improved agricultural and rural statistics. It can be used as a guide by staff of national statistical offices, environmental ministries and other relevant national agencies, to understand the international context of international climate policy (Ch. 2) and international guidelines (Ch. 3), identify needs for improved agricultural and rural data as well as emission estimates towards improving GHG Inventories (Ch. 4), while supplying practical information and examples based on accessing and using the FAOSTAT Emissions database for agriculture and land use (Ch. 5).
