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 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 کاملEvaluation of Virtual Water and Water Footprint of Crop Production (Case study: Qaleganj County)
To address the optimal use of available water resources, a revisit of water resource allocation and management is needed. Water use and water footprint of every product varies in different geographical areas due to various climate, agricultural operations and water efficiencies. Thus, more productive management schemes are to be developed. The goal of this study is to assess the virtual water a...
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 کاملThe water footprint of poultry, pork and beef: A comparative study in different countries and production systems
Agriculture accounts for 92% of the freshwater footprint of humanity; almost one third relates to animal products. In a recent global study, Mekonnen and Hoekstra (2012) [31] show that animal products have a large water footprint (WF) relative to crop products. We use the outcomes of that study to show general trends in the WFs of poultry, pork and beef. We observe three main factors driving th...
