The environmental impact category analyzed in this assessment was land use. After reviewing existing information regarding land use in agriculture and livestock production, analysis for US pork production was performed at two scales: cradle-to-grave and cradle-to-farm gate. The cradle-to-grave analysis provided a scan-level overview of land use associated with the production and consumption of lean pork at an aggregated national level. The cradle-to-farm gate analysis provided a more granular assessment of the land use required for live swine production, and evaluated the use of alternate ration formulation as a tool for reducing environmental impacts. This report summarizes the results of this project, which was divided into the following tasks:
Task 1: Review existing literature of land use in animal agriculture production
Task 2: Conduct a scan-level LCA of land use in the pork supply chain
Task 3: Conduct a detail-level LCA of live swine production for land use
Task 4: Complete final written reports.
