Accurate monitors are required to determine ambient concentration levels of contaminants emanating from concentrated animal feeding operations (CAFOs), and accurate models are required to indicate the spatial variability of concentrations over regions affected by CAFOs.
Because the number of farms producing livestock and poultry has dropped more than 80%, despite increasing production (Miner et al. 2000), there is now a significant concentration of animals within a given farm [or concentrated animal feeding operation (CAFO)] as well as an increased localization of these CAFOs within relatively few regions of the United States.
In addition, the Pennsylvania Department of Environmental Protection requires NMPs from the largest operations called concentrated animal feeding operations (> 1,000 AEUs, or 301 1,000 AEUs and a concentrated animal operation, or per federal regulation) (U.S. Environmental Protection Agency 2012).
Ms. Niman's real objection seems to be to large concentrated animal farms.
Crowded into "concentrated animal feeding operations," or CAFOs, they can produce entire cities' worth.
The innovation could help to clean up the image of large livestock farms known as concentrated animal feeding operations (CAFOs).
The meadows have a characteristic smell compounded of the briny ooze, factory smokestacks, and concentrated animal husbandry.
Yes, concentrated animal feeding operations, or "factory farms" as you call them, are a key feature of modern agriculture.
Lynn Henning of the United States, a family farmer, exposed the water pollution caused by concentrated animal-feeding operations.
New York's regulations for concentrated animal feeding operations are among the toughest in the nation and go well beyond what the federal Clean Water Act requires.
