Dublin scientists support call for ‘balanced view on meat’

James Nason, October 24, 2022

Presenters at the two-day summit on the societal role of meat in Dublin included Declan Troy from Ireland, Jason Rowntree, United States; Willhelm Windisch, Germany; Nick Smith, New Zealand; Peter Ballerstedt, US; Shirley Tarawali, Kenya; Paul Wood, Australia; Neil Mann, Australia; Peer Ederer,  Switzerland; Max Makuvise, Zimbabwe; Theo de Jager, South Africa; Pablo Manzano, Spain; Diana Rodgers, US; Alice Stanton, Ireland; Bradley Johnson, US and Frederic Leroy, Belgium.


SCIENTISTS from around the world have gathered in Dublin to examine claims regularly levelled against meat and livestock and to confront the simple question: What does the science say?

The unequivocal conclusion from two days of detailed presentations by scientific experts from Australia, the US and across Europe is that the highest standards of science do not justify or support the “simplistic and reductionist” war being waged against meat.

In fact, while challenges remain to minimise the livestock farming and meat sector’s environmental footprint, a clear theme of the many academic assessments presented in Dublin was that removing livestock and meat from landscapes and human diets would lead to potentially disastrous outcomes for both.

Livestock systems are “too precious to society to become the victim of simplification, reductionism or zealotry,” a document signed by the scientists present – billed the “Dublin Declaration” – emphatically states.

Scientists from around the world are now being called on to sign the Dublin Declaration (see link here) which aims “to give voice to the many scientists around the world who research diligently, honestly and successfully in the various disciplines in order to achieve a balanced view of the future of animal agriculture”.

It also pointedly warns against “one-size-fits-all agendas”, such as drastic reductions of livestock numbers which could lead to “environmental problems on a large scale”.

Full outcomes and evidence from the two-day International Summit on the Societal Role of Meat will be published in a special addition of the Animal Frontiers in March 2023.

Simultaneous events highlighting the science supporting the positive role of livestock farming and meat production are expected to be held at the same time, including in Australia.

Evidence presented at the forum reinforced several take home messages including that:

  • For millennia, livestock farming has provided humankind with food, clothing, power, manure, employment and income as well as assets, collateral, insurance and social status.
  • The highest standards of bio-evolutionary, anthropological, physiological, and epidemiological evidence confirm that the regular consumption of meat, dairy and egg, as part of a well-balanced diet is “advantageous for human beings”.
  • Livestock-derived foods are the most readily available and “bio-available” source of high-quality proteins and several essential nutrients and other health-promoting compounds for people all over the world”.
  • Farmed and herded animals are irreplaceable for maintaining a circular flow of materials in agriculture, by recycling in various ways the large amounts of inedible biomass that are generated as by-products during the production of foods for the human diet.
  • Livestock are also optimally positioned to convert these materials back into the natural cycle and simultaneously produce high-quality food.
  • Ruminants in particular are also capable of giving value to marginal lands that are not suitable for direct human food production.
  • Additionally, well-managed livestock systems applying agro-ecological principles can generate many other benefits, including carbon sequestration, improved soil health, biodiversity, watershed protection and the provision of important ecosystem services.
  • Livestock ownership is also the most frequent form of private ownership of assets in the world and forms the basis of rural community financial capital. In some communities, livestock is one of the few assets that women can own, and is an entry point towards gender equality.
  • Policy recommendations need to be based on clear, scientific evidence and must not not ignore the protections against nutritional deficiencies afforded by animal sourced foods
  • Dramatic reductions in livestock numbers would heavily impact poorer countries. At least half a billion people around the globe are “totally dependent on livestock” for their livelihoods.

“Livestock is the millennial-long-proven method to create healthy nutrition and secure livelihoods, a wisdom deeply embedded in cultural values everywhere,” the Dublin Declaration states.

“Sustainable livestock will also provide solutions for the additional challenge of today, to stay within the safe operating zone of planet Earth’s boundaries, the only Earth we have.”

Many who spoke at the summit over the two days called for the “polarised” and “binary” nature of public discussions around meat and livestock to end.

Ireland’s Minister of State at the Department of Agriculture, Martin Heydon, noted in his opening remarks that “so much of what we see and read and consume has been “boiled down into sound bites that have been very much simplified”.

It has bever been more important to move forward with an accurate and scientific understanding of meat’s role in society, he said.

“Consumers need to trust their food and where it comes from.

“And where does that trust from? It comes from science.”

Professor Frank O’Mara, the director of Ireland’s agricultural research and development organisation Teagasc, which hosted the summit, said the role of livestock has never been as questions as much as it is being questioned now.

“We all understand and get that we need to have a very sustainable system of agriculture,” he said.

“The point we would make is you can’t have a sustainable and properly function food system without livestock being part of that, because of the circular process of crop production and animal production.

“So we certainly need livestock to be part of the food system to feed the 10 billion people we will have on this planet shortly, and do it in a sustainable manner.”

“When there is fog around, the one thing that helps clear the fog is evidence-based information,” he said.

South African farmer and former president of the World Farmers Organisation, Dr Theo de Jager, said farmers needed to be part of the global conversation: “Farmers are the ones who everyone is talking about but no one is talking to,” he said.

About 200 people attended the summit including scientists, agricultural representatives and policy makers from around the world.

It was two years in the making and was coordinated by a committee comprising Peer Ederer, Founder, GOALSciences, Switzerland; Frédéric Leroy, Professor, Vrije Universiteit Brussel, Belgium; Rod Polkinghorne, CEO, Birkenwood International, Australia; Graham Gardner, Professor, Murdoch University, Australia;  Collette Kaster, CEO, American Meat Science Association, USA; Mohammad Koohmaraie, President, Meat Division, IEH Laboratories and Consulting Group, USA and Declan Troy, Assistant Director of Research, Teagasc, Ireland.

    We believe that the consumption of nutritious meats will continue to be important.

    As a lifelong supporter of mixed farming and balanced diets I’ve been delighted to read of the outcomes of the discussions which have taken place in Dublin. The Dublin Declaration is a particularly spectacular achievement drawing together as it does the combined wisdom of involved scientists from all over the world. Drawing such a comprehensive set of conclusions together will have been a mammoth operation. It deserves the support of livestock producers everywhere and needs to be properly understood by all consumers who have an interest in the part played by livestock; not only in contributing to healthy people, but also the contribution made by animals to protecting that tiny crust of soil which exists around the planet earth and ensures that crops can be grown.

    I support this. Well said. A much needed perspective.

  4. John Thorley, November 1, 2022

    I believe this Dublin Declaration to be one of the most important and clear statements to be made on behalf of farmers globally. It identifies with the fact that meat and animal products have a continuing part to play in the lives of mankind and that farming — be it to produce grass for pasture or grain crops to be fed to animals to grow into meat, milk and eggs for human consumption — is an unambiguous and unequivocal statement of fact.

    Thank goodness a scientific counter balance emerges to the unabashed emotional claims of fanatical environmentalists. The problem is logic seldom overcomes emotion.

    To all the vegans: up your acrylic jumpers.
