Innovative Scientific Approaches Aim to Tackle Methane Emissions in Ireland's Agricultural Sector

Methane poses a significant challenge to the Irish dairy and beef sectors. However, researchers from Ireland and Britain are developing new scientific solutions to reduce emissions through feed additives and breeding techniques.

Methane and Its Impact

Methane, produced by ruminants such as cattle and sheep, is 86 times more potent than carbon dioxide in terms of greenhouse effect. This substantial impact on global warming presents an existential threat to the dairy and cattle industries globally.

Scientific Strategies to Combat Emissions

During an online briefing organized by the Science Media Centre Ireland, researchers outlined strategies to reduce methane production in farm animals. Dr. Sinéad Waters, a microbiologist at the University of Galway, emphasized the role of the animal microbiome in methane production and the emerging mitigation strategies.

Prof Chris Reynolds of the University of Reading highlighted the effectiveness of feed additives like Bovaer and Asparagopsis seaweed in reducing methane emissions, which offers significant promise for sustainable agriculture.

Breeding Techniques for a Sustainable Future

Prof Richard Dewhurst of Scotland’s Rural College explained efforts to use breeding techniques, such as selective sexing and in-vitro fertilization, to produce low methane-emitting livestock. This approach aims at long-term sustainability through cumulative genetic progress.

Dr. John Hammond from Surrey’s Perbright Institute discussed the potential development of a vaccine to target methanogenic bacteria in cattle, further addressing methane emissions at the microbial level.

Regulatory and Consumer Challenges

As Waters notes, while Ireland is positioned to meet targets with these strategies, challenges remain in gaining regulatory approval and addressing consumer concerns. Engagement and communication with the public are essential to foster trust in scientific advancements.
