Biomass use, production, feed efficiencies, and greenhouse gas emissions from global livestock systems.
We present a unique, biologically consistent, spatially disaggregated global livestock dataset containing information on biomass use, production, feed efficiency, excretion, and greenhouse gas emissions for 28 regions, 8 livestock production systems, 4 animal species (cattle, small ruminants, pigs, and poultry), and 3 livestock products (milk, meat, and eggs). The dataset contains over 50 new g...
متن کاملGreenhouse gas emissions in livestock production systems
Agriculture is responsible for a significant proportion of total anthropogenic greenhouse gas emissions (perhaps 18% globally), and therefore has the potential to contribute to efforts to reduce emissions as a means of minimising the risk of dangerous climate change. The largest contributions to emissions are attributed to ruminant methane production and nitrous oxide from animal waste and fert...
متن کاملLocalising livestock protein feed production and the impact on land use and greenhouse gas emissions.
Livestock farmers in Sweden usually grow feed grains for livestock but import protein feed from outside Sweden. Aside from the economic implications, some environmental issues are associated with this practice. We used life cycle assessment to evaluate the impact of local protein feed production on land use and greenhouse gas emissions, compared with the use of imported protein feed, for pig me...
متن کاملGreenhouse Gas Emissions from Livestock and Poultry
In 2008 the Environmental Protection Agency (EPA) estimated that only 6.4% of U.S. greenhouse gas (GHG) emissions originated from agriculture. Of this amount, 53.5% comes from animal agriculture. Agricultural activities are the largest source of N2O emissions in the U.S. accounting for 69% of the total N2O emissions for 2009. In animal agriculture, the greatest contributor to methane emissions ...
متن کاملThe Carbon Navigator: a decision support tool to reduce greenhouse gas emissions from livestock production systems.
The Carbon Navigator has been developed to support the objective of reducing the carbon intensity of the dairy and beef sectors of Irish agriculture. The system is designed as a knowledge transfer (KT) tool aimed at supporting the realisation at farm level of the mitigation potential. The objective of this paper is to outline the potential role of KT in reducing greenhouse gas emissions in the ...
