Spatial Variability and Uncertainty of Water Use Impacts from U.S. Feed and Milk Production.

摘要: This paper addresses water use impacts of agriculture, developing a spatially explicit approach tracing the location and scarcity related to feed production, transport, livestock, tracking uncertainties illustrating with case study on dairy production in United States. was developed as step bring variable into process-based life cycle assessment (LCA) context. As resources demands are variable, it is critical take account activities properly understand use, accounting for each main feeds milk production. At crop level, example corn grain shows that 59% stress associated States located Nebraska, state moderate (11%). level four watersheds 78% national str...
