Insights from the European Federation of Animal Science (EAAP) 2024 Annual Meeting: Shaping the Future of Livestock Science and Sustainability
In early September, I had the privilege of attending the 75th EAAP Annual Meeting of the European Federation of Animal Science in Florence, Italy. As the largest European congress dedicated to animal science, it brought together over 2,000 participants from around 60 countries, making it a hub for discussing advancements in sustainable livestock production.
The conference theme, “Global Quality: Environment, Animals, Food,” explored the critical intersections of livestock farming systems, genetics, nutrition, animal welfare, and climate change. Here are the highlights from the sessions I attended, organized around some of the key topics shaping the future of our food systems and the livestock industry.
Livestock: Beyond Food Production
One of the sessions that stood out was “Livestock are More than Food,” which showcased the multifaceted roles of livestock in our society. Beyond meat and milk, livestock contribute to:
- Ecosystem services like soil health, biodiversity, and carbon sequestration.
- Production of pharmaceuticals, cosmetics, biofuels, and leather.
- Circular systems that recycle nutrients and waste, integrating livestock into broader sustainable farming practices.
This session emphasized that livestock’s role in global sustainability goes far beyond food, challenging us to think about their value from a holistic perspective.
Adapting Livestock Farming to Climate Change
Climate change was a recurring theme, with several sessions addressing how livestock farming can adapt and contribute to mitigation efforts.
In the session “The Current and Future Role of Pasture Production Systems in Mitigating and Adapting to Climate Change Impacts,” I learned about:
- Resilient grazing systems: Research from Ireland showed that diverse forage species (multispecies swards) are more resilient to climate change impacts compared to traditional monocultures, providing improved ecosystem services.
- Carbon footprint of sheep farming: The LIFE Green Sheep Project, which spans five European countries, revealed how carbon storage in grazing systems can offset emissions in sheep production.
- Nitrogen management: Incorporating plantain into forage mixes for dairy cows was shown to reduce urinary nitrogen excretion, demonstrating a practical way to lower agricultural nitrogen losses.
The Future of Dairy Farming
The session on “Viable Future Dairy Farming Systems” delved into sustainability from production, environmental, and consumer viewpoints. Key takeaways included:
- The importance of multicriteria assessment for sustainability, integrating environmental, economic, and social dimensions.
- Utilizing plant-animal systems to optimize circularity, such as using crop residues for feed and manure for crop production.
- Adopting True Cost Accounting (TCA) to internalize the environmental and social impacts of dairy farming, promoting a more balanced food system despite potential increases in food prices.
Metrics and Technologies for GHG Mitigation
Livestock’s contribution to greenhouse gas emissions was another hot topic. During the session “Technologies for GHG Emission Mitigation on Farm: Options, Opportunities, and Challenges,” we discussed:
- Methane reduction strategies: Technologies like rumen manipulation, optimized diets, and selective breeding show promise, though scaling these requires significant investment and climate finance.
- The debate over GWP vs. GWP100:* GWP* offers a more accurate metric for methane’s climate impact, highlighting its short-lived nature compared to CO2. Studies suggest livestock emissions under GWP* may even have a cooling effect, challenging traditional GWP100 assessments.
Navigating the EU Green Deal in Dairy Farming
The EU Green Deal’s ambitious goals—ranging from reducing greenhouse gas emissions to improving biodiversity—present unique challenges and opportunities for the livestock sector. In the session “How the Dairy Sector Copes with the EU Green Deal,” discussions focused on:
- Technological innovations: The Netherlands is pioneering tools like the cow toilet (which reduces ammonia emissions by 33%) and the Lely Sphere (cutting ammonia emissions by 75%).
- Cultured meat as an alternative: While it promises lower environmental impact and improved animal welfare, questions remain about its sustainability, safety, and societal acceptance.
Reassessing Our Relationship with Farmed Animals
The session “Reassessing Our Relationship with Farmed Animals” explored shifting consumer trends, particularly in Europe. Topics included:
- Increasing demand for high-welfare animal products.
- Nutritional challenges, such as balancing dietary iron intake in plant-based diets versus animal-sourced foods.
- Debates on whether the future of food leans toward veganism or sustainable livestock practices.
Reflections and Looking Ahead
The EAAP 2024 conference was an incredible opportunity to learn from global experts, explore cutting-edge research, and engage in meaningful dialogue about the future of livestock systems. From the role of diverse pasture systems to the challenges of aligning with the EU Green Deal, it’s clear that sustainable livestock farming is a complex but vital part of our global food systems.
