They are reducing enteric methane emissions
Australian Beef Farmers' Efforts to Reduce Enteric Methane Emissions
Feed Additives
The Australian government has invested in research and development for methane-reducing feed additives and forage legumes for livestock. Feed additives such as Polygain, Agolin, and probiotics have been shown to reduce methane emissions by 34%, 15%, and 10%, respectively. These additives inhibit the production of methane in the digestive systems of animals. Additionally, the government has funded the development of technologies to deliver these feed additives to grazing livestock.
Asparagopsis
The Australian government is also supporting the commercialisation of Asparagopsis, a native red seaweed, as a methane-reducing livestock feed additive. Asparagopsis supplements are estimated to be applied to 20% of Australian ruminants by 2030. This initiative is expected to result in a 20% reduction in enteric methane emissions, which equates to 13 Mt less carbon dioxide equivalents released annually by Australian farmers.
Selective Breeding
Selective breeding in dairy cattle has been shown to reduce methane emissions by 20-26% over ten years, although this comes at the cost of reduced genetic gains for production traits. The implementation of genetic selection for beef cattle is more straightforward in Australia through the BREEDPLAN tool, which allows farmers to include methane mitigation traits in their breeding stock.
Grazing Management
Improved grazing management systems for beef cattle can lead to reductions of approximately 20% in methane emissions. Key strategies include increasing the ratio of live weight to age, reducing the average age and proportion of unproductive animals in the herd, and adjusting the relative numbers of each livestock class.
Carbon Sequestration
Some Australian beef producers have achieved carbon neutrality or low-carbon systems by storing more CO2 than is emitted from their operations. This is done through practices such as planting trees in optimal locations and identifying pasture species that promote increased soil carbon stocks.
Australian beef farmers are actively addressing the challenge of reducing enteric methane emissions through a range of innovative approaches, demonstrating their commitment to environmental sustainability and their role in mitigating climate change.

They are improving soil structure and fertility
Australian beef farmers have been adapting to climate change by improving soil structure and fertility.
Soil structure and fertility are influenced by several soil-based parameters, including moisture, aerobiosis, temperature, the amount and form of carbon, organic and inorganic nitrogen, pH, and cation exchange capacity. Soil aggregation and pore characteristics, such as porosity and pore size, also play a crucial role in soil health and function.
By adopting specific management practices, farmers can enhance soil structure and fertility. One such practice is tillage, which has been a focus of Australian agriculture for several decades. Tillage practices have evolved from aggressive techniques to more conservative approaches with fewer passes. This transition has been shown to reduce greenhouse gas emissions from agricultural soils, which are significant contributors to climate change.
Additionally, Australian beef farmers are exploring no-till practices, cover crops, and agroforestry to mitigate greenhouse gas emissions further and improve soil health. No-till systems gained traction in the 1980s due to economic incentives and have since been refined to minimize soil disturbance and maximize carbon sequestration.
Furthermore, improving soil fertility is a crucial adaptation strategy in regions with increasing temperatures and declining rainfall, such as southeastern Australia. By increasing soil fertility and utilizing summer-active pasture species, farmers can mitigate the impact of climate change on pasture production and maintain adequate ground cover to prevent soil degradation and erosion.
To support these efforts, research is being conducted to help farmers adopt practices that enhance soil fertility and sequester carbon. This includes the development of technology for measuring soil carbon levels, identifying optimal locations for tree planting, and selecting pasture species that promote increased soil carbon stocks.
By focusing on improving soil structure and fertility, Australian beef farmers are not only adapting to climate change but also contributing to the global effort to reduce greenhouse gas emissions and promote sustainable land management practices.
