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 (stand-alone)(Draft) Methodology for Quantification of GHG Emission Reductions from Improved Management in Smallholder Dairy Production Systems using a Standardized Baseline 2016
Also available in:
No results found.This methodology presents requirements for development and assessment of a standardized baseline for quantification of greenhouse gas (GHG) emission reductions in smallholder dairy systems. It also includes guidance for quantification of baseline GHG emissions from dairy production in a defined geographical area within a country, for quantification of with-project GHG emissions, leakage, and net emission reductions due to project implementation. The general approach outlined in the methodology i s based on the following key elements. A standardized baseline for the project region is set on the basis of a baseline survey, which establishes a statistically robust relationship between milk yields and the GHG intensity of milk production measured as kg CO2 eq. per kg fat and protein corrected milk (FPCM). -
Book (stand-alone)Improving feed conversion ratio and its impact on reducing greenhouse gas emissions in aquaculture 2017
Also available in:
No results found.The study (workshop presentations, proceedings, GHG tool and recommendations) was carried out to improve FCR and asses its impact on reducing GHG emissions in Aquaculture. Three major objectives of this study was to assess the current GHG contributions of aquaculture and ways to measure it, ii) explore the potential to continue reducing FCR in salmon farming and other species, and therefore improving their environmental performance including GHG and iii) explore potential transfer of feed and fe eding technologies and lessons learn from salmon farming to other freshwater species such as tilapia, carps and catfishes and marine shrimp. The findings of this study identified several factors that affect FCRs, particularly in species farmed in developing countries, which could be targeted with programs that ultimately would reduce GHG and other emissions. The study concluded that managing environmental aspects, simplifying farm management, and improving feed management, would improve FCRs and reduce GHG emissions.
