The Carbon Footprint of Beef Production
Modern-day agriculture allows the average farmer to produce enough food to feed 125 other people. This is in sharp contrast to the historical agricultural systems exemplified by farming in the 1800s, when each farm could produce only enough food to feed one other family. The global population has increased in line with productivity, yet the rate of increase in meat consumption is greater than t...
متن کاملCarbon Footprint of Beef Cattle
The carbon footprint of beef cattle is presented for Canada, The United States, The European Union, Australia and Brazil. The values ranged between 8 and 22 kg CO2e per kg of live weight (LW) depending on the type of farming system, the location, the year, the type of management practices, the allocation, as well as the boundaries of the study. Substantial reductions have been observed for most...
متن کاملCarbon footprint and ammonia emissions of California beef production systems.
Beef production is a recognized source of greenhouse gas (GHG) and ammonia (NH(3)) emissions; however, little information exists on the net emissions from beef production systems. A partial life cycle assessment (LCA) was conducted using the Integrated Farm System Model (IFSM) to estimate GHG and NH(3) emissions from representative beef production systems in California. The IFSM is a process-le...
متن کاملEfficiency of Dairy Production and its Carbon Footprint
The productivity of the American farmer has increased dramatically over the last century. One hundred years ago a farmer produced enough to feed 15 people and over 40% of the US population was involved in agriculture-related businesses. Today the produce from an average farmer feeds 130 people and farmers represent less than 2% of the U.S. population. The increases in agricultural productivity ...
متن کاملTwinning in Beef Cattle: an Opportunity to Improve Reproductive and Economic Efficiency of Beef Production?
The possibility of improving the rate of reproduction in beef cattle by selection for an increased rate of twinning has been debated with both pessimism and optimism since the early days of animal breeding. The success of selection for multiple births in sheep lifted hopes that a similar program for cattle would also be successful. Pearl (1912) wrote, “From the standpoint of practical breeder i...
