Greenhouse emissions from agriculture target of research; methane and nitrous oxide loss wasting potential production resources

For practical reasons agriculture and land-use emissions would be excluded from the National Greenhouse and Energy Reporting Bill 2007, although energy use in agriculture would be captured under these provisions, said Liberal MP Judi Moylan in the Federal House of Representatives on 12 September 2007. Farming prime source of two greenhouse gases: “The farm community that I represent will be pleased at the way in which this is being developed, because the Australian Greenhouse Office will undertake research and development in partnership with industry to consider ways to reduce methane from livestock systems and nitrous oxide from land management systems,” Moylan said. “According to the Australian Greenhouse Office, agriculture is Australia’s largest source of methane and nitrous oxide emissions. The Australian Greenhouse Office lists the emissions that primarily come from agriculture:

• methane from enteric fermentation in livestock;

• nitrous oxide from inefficient use of nitrogen in agricultural soils;

• methane and nitrous oxide from the burning of savannas; and

• small contributions from manure management, rice cultivation and the field burning of agricultural residues.”

Resources being wasted: “… emissions from livestock and agricultural soils represent a loss of valuable carbon and nitrogen resources,” Moylan said. For example, it was estimated that methane emissions from livestock represented a loss of up to 15 per cent of potential energy that could otherwise be used for animal production. Similarly, the loss of nitrous oxide from soils represented a loss of valuable nitrogen that could otherwise be used for plant production. Reductions in agricultural emissions would lead to productivity benefits for agricultural industries and provide a win-win for agricultural production and environmental sustainability. The Australian Greenhouse Office was working with industry to research and develop ways to reduce greenhouse emissions from agriculture, Moylan said.
