Published online by Cambridge University Press:  11 April 2025

Abstract

One Health is an approach to managing complex health threats by promoting multisectoral and multidisciplinary collaboration, engaging stakeholders, and contributing to sustainable development, while fostering equity and socioecological equilibrium across sectors and living species. Legislation is crucial for advancing One Health by establishing structures that foster collaboration, define roles and responsibilities, and support sustainable outcomes. To enhance its effectiveness, One Health must be integrated into legal frameworks addressing global challenges at the intersection of human, animal, plant, and ecosystem health, through flexible, context-specific legal frameworks adaptable to emerging and evolving threats.

This paper identifies four legal elements for embedding One Health into legislation: (i) normative integration (bridging different legal domains); (ii) multisectoral and multidisciplinary collaboration; (iii) stewardship and the sustainable management of common goods beyond human interests; and (iv) stakeholder engagement, ensuring inclusive participation. These elements are interconnected and interdependent, collectively forming a comprehensive foundation for integrating One Health into legal frameworks. They have the potential to dismantle sectoral silos, foster multidisciplinary collaboration, and advance stakeholder engagement and the recognition of the intrinsic value of all species. At the same time, these elements also function as strategies, offering practical pathways for legislative design and implementation. The paper also provides examples of their implementation and suggests avenues for future research.

Review: Legal elements to operationalise One Health: from principles to practice — R0/PR2

Comments

This is a very useful paper on a critical component of One Health implementation. It clearly sets out the reasons why legal mechanisms are required to operationalise the principles of One Health and gives several useful and practical examples of how this could be done.The four elements which the author identifies align with the overarching One Health approach, addressing institutional coordination, normative integration and stakeholder participation, and situates these within the relevant concepts of sustainable development and interspecies equity. The comparative analysis of international mechanisms provides a valuable illustration of existing tools which could be usefully expanded other jurisdictions. Overall, the paper presents a compelling case for great focus on law and legal systems as core sites for One Health research and advocacy.

Review: Legal elements to operationalise One Health: from principles to practice — R0/PR3

Comments

The paper is well written and provides important insight. My two main concerns are first, that I do not know to what extent it really contributes to the literature, and second, it feels too abstract. I think the solution to the first main concerns is simply asking the author to tell the reader how this manuscript contributes to the literature. As to the second concern, I would invite the authors to consider whether it’s possible to make the paper much more concrete and elaborate on the examples that are currently way too brief. For example, the author seems to praise the moral inclusiveness of the OHHLEP. But how does the intrinsic value of all living creatures currently plays a role in national legislation? I am guessing very little, so what does that mean for OH and its legal and ethical underpinnings? Moreover, what should we do when human interests and animal/ ecological interests collide? How could and should OH legislation prevent that or solve it once it happens? What happens if interests of aboriginals conflict with non-human entities with intrinsic moral value?

Addressing these two main points will require some effort, but I do think it will make the paper much stronger and more useful.

Specific comments follow below:

-““One Health is an integrated, unifying approach that aims to sustainably balance and 31 optimise the health of people, animals and ecosystems. It recognises the health of 32 humans, domestic and wild animals, plants, and the wider environment (including 33 ecosystems) are closely linked and interdependent. The approach mobilizes multiple 34 sectors, disciplines and communities at varying levels of society to work together to foster 35 well-being and tackle threats to health and ecosystems, while addressing the collective 36 need for healthy food, water, energy, and air, taking action on climate change, and 37 contributing to sustainable development” (OHHLEP, 2022).”

This quote precedes the explanation of OH and OHHLEP. It should be the other way around.

-“The concept of One Health”

To me the introduction is disorganized. I would start with a discussion of OH, and linking it to OHHLEP, then linking it to law.

-“This paper aims to identify legal elements and strategies that create an enabling 62 environment for One Health, providing a framework for collaboration and accountability. 63 “Legal elements” refers to the mechanisms that laws use to achieve their regulatory 64 objectives and facilitate compliance, such as institutional powers and responsibilities, 65 stakeholders’ rights and obligations, licenses and permits. The main research question 66 is: How can legislation facilitate the incorporation of the One Health approach and its key 67 underlying principles? Specifically, what legal elements are necessary to create an 68 enabling environment for One Health across different sectors?”

I am not a lawyer, so this might stem from my own ignorance. But I felt that the author should have emphasized whether the focus here is national or global legislation.

-“recognizing their 81 interdependence and recalling the environmental law principle of integration”

I hope that the author explain this principle ahead for readers who are not familiar with environmental law.

-“ OHHLEP’s definition of One Health”

The paper relies heavily on this definition. It would be useful to explain why this particular definition out of many others was espoused.

-“ The principles of equity and socioecological equilibrium demand the recognition of the intrinsic 117 value of all living beings as a moral imperative, as well as the acknowledgement of 118 biodiversity and natural resources as global public goods.”

I wonder whether the author would want to elaborate here. The idea of Public goods traditionally applies to humans. If we are serious about the intrinsic value of all living creatures then public goods are not enough. The author can, for instance, consult literature in bioethics that discusses the idea of a universal goods. Notice also that legislation for this idea of intrinsic good for all living creatures may require much more political courage and innovation than the other principles that are more mainstream such as interdisciplinary.

-“ Arguably, OHHLEP principles represent an evolution, and a synthesis of the ideas 143 encapsulated in Berlin, with a renewed emphasis on equity and socioecological 144 equilibrium.”

What is the evolution? It’s better to be as specific as possible rather than vague.

-as a non legal scholar, the principles overall make sense. What is missing to me is first a review of the literature to see if anything has already been written on OH legislation and explaining how this paper is different, and second, a more in-depth review of existing OH laws and showing their advantages and shortcomings. This could be made in a table form and will make this paper much stronger.
