Boffins unite to stem bovine methane

13 Jul, 2012 04:00 AM

SIX Australian universities, researchers in Canada and the CSIRO’s Sustainable Agriculture Flagship will look at ways to reduce methane emissions from cattle.

Professor Deli Chen from the University of Melbourne’s School of Land and Environment said agriculture directly accounted for 16 per cent of Australia’s overall greenhouse gas emissions and the grazing lands of northern Australia were thought to be responsible for about one-third.

He said accurately measuring methane emissions from livestock under real grazing conditions was a critical first step before mitigation could be considered.

“Our research may also help boost the productivity of the cattle industry in a more sustainable way because an estimated 2–12 per cent of the energy ingested by cattle is lost as methane waste, reducing beef production and costing graziers money,” Professor Chen said.

The team will use a range of sophisticated instruments including open path lasers and Fourier Transform Infrared Spectroscopy (FTIR) as well as aircraft mounted cavity ring-down spectroscopy (CRDS) based detectors to measure methane in the atmosphere.

A laser beam is sent across a paddock for a few hundred metres and then reflected back to a detector, allowing emission levels to be calculated using computer modelling.

CSIRO’s Research Project Leader, Dr Ed Charmley, said the Australian Government’s Clean Energy Act set a long-term goal of reducing greenhouse gas emissions by 80 per cent of 2000 levels by the year 2050.

“The Cluster will also develop science that supports methodology development for the Carbon Farming Initiative, an Australian Government program that enables farmers to earn ‘carbon credits’ for undertaking abatement activities on their properties,” Dr Charmley said.

CSIRO’s Flagship Collaboration Fund will fund the Cluster for three years, with support from several other Australian universities including Macquarie University, RMIT, University of New England, University of Western Australia, and University of Wollongong as well as researchers at Agriculture and AgriFood Canada and the University of Alberta.

What a crock - cattle are ruminents and process by rechewing and fermentation, so ya going stop the cows from "farting" ... use bungs then

Talk about a total waste of time. With cane toads ravaging the country these people are trying to stop cow farts ? PPfffff

True Grit and XFACTOR - methane removal in ruminants is achieved almost exclusively via the mouth by eructation (belching) . Farting is irrelevant in this context .

Whether its belching or farting Oliver its still a waste of time.

If they succeed in stopping the bloat problem the benefits will recover the cost. Otherwise, bovine methane is part of an existing, stable cycle, warranting no concern whatever on the AGW front.

Interesting days! Perhaps M.G. is getting it right. More than Bonlac did. Naturally Fonterra is

The good Senators could initiate the disallowance motion, but it seems even the Greens won't do

Excellent plan. Can we do it wherever we have previously sent live exports?
