New research reveals unintended environmental and economic consequences of U.S. beef farmers and ranchers not using technologies.
New research presented at the 2012 American Society of Animal Science meeting provided insight into the consequences if U.S. farmers and ranchers no longer used productivity-enhancing technologies to raise beef cattle. If technologies were withdrawn, 17 million more acres of land and 138 billion more gals. of water would be required to produce the same total amount of beef. At the same time, 18 million extra metric tons of carbon dioxide equivalent (CO2) would be released in the U.S. alone and 16.9 million acres of forests would be destroyed in other countries. Overall, the U.S. beef supply would decrease 17%, stimulating more beef production in other countries.
“Global demand for safe, affordable beef has increased during the last 50 years, and U.S. producers have responded by adopting innovative products and management practices that help them produce more lean beef,” says Jude Capper, Washington State University adjunct professor and author of the peer-reviewed study. “If use of these scientifically proven, U.S. Food and Drug Administration (FDA)-approved technologies were discontinued, our research shows the end result would be sobering: more cattle, more land and more water needed to produce the same amount of beef, and more CO2 released into the atmosphere.”
Novel approach used to quantify the effects
The research looked at two U.S. beef-production systems that were identical in all ways but one: whether or not productivity-enhancing technologies were used.
- The conventional system analyzed included FDA-approved ionophores, steroid implants, melengestrol acetate (MGA) and beta-adrenergic agonists used at current adoption rates.
- The no-technology system did not use any of these products.
Capper used a new whole-system environmental and natural resource model to determine the effects of using each system to produce the same amount of beef. This model included all inputs and outputs throughout beef production, from the manufacture of cropping inputs (fertilizers and pesticides) to the arrival of animals at the processor.
Dermot Hayes, Iowa State University economist, then fed the results into the Center for Agricultural and Rural Development model – which includes a greenhouse-gas assessment – to understand the global agricultural-production and trade consequences.
“Our goal was to make this research as accurate and as real as possible,” Capper says. “That’s why we turned to the best available resources, from the models used to prepare briefings for U.S. trade representatives and congressional leaders, to the newly developed whole-system environmental model.”
