Book (stand-alone)Global database of GHG emissions related to feed crops - A life cycle inventory - Version 1 2017
Also available in:
No results found.This report presents the life cycle inventories of the five studied crops. Section 2 of the document presents the type of data that can be sourced from the database, the data collection methods, and highlights the data gaps. Section three presents the life cycle inventory providing information on the data and data sources, assumptions and data gaps and how these were addressed. The Annexes provide information on crop yield distributions, data on nitrogen application rates, pesticide use and in formation on field processes and machinery use. -
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. -
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.
