FAO releases new report on greenhouse gas mitigation

Published on: Jun 13, 2013

The U.N. Food & Agriculture Organization has released a new report, "Mitigation of Greenhouse Gas Emissions in Livestock Production: A Review of Technical Options for Non-CO2 Emissions," that presents a "unique and exhaustive review of current knowledge on mitigation practices" for greenhouse gas emissions in the livestock sector. The 230-page report focuses specifically on non-carbon dioxide emissions from enteric fermentation and manure management, according to the report's editors.

The editors' preface explained that the review was prompted by a "lack of comprehensive, science-based and consolidated information" on existing greenhouse gas mitigation practices applicable to different livestock production systems across the globe.

The report references more than 900 publications on the mitigation of direct nitrous oxide and methane emissions and highlights the most promising options, given their demonstrated effectiveness and feasibility for adoption, FAO said. The review was deliberately limited to in vivo experiments to reflect what can be achieved with available mitigation practices.

This in-depth assessment will inform the livestock industry, academia, governmental and non-governmental organizations that are interested in identifying and designing mitigation interventions for the sector. It will also help to identify research and development priorities in the area.

The report, available at http://www.fao.org/docrep/018/i3288e/i3288e.pdf, was authored by a group led by Alexander Hristov of Pennsylvania State University that included personnel The Ohio State University, U.S. Department of Agriculture/Agricultural Research Service, University of Florida, Agriculture & Agri-Food Canada, the Innovation Center for U.S. Dairy, University of California-Davis, DairyNZ in New Zealand and Wageningen University in the Netherlands.
