4. One Introduction Introduction What is One Health?

5. One Health is an integrated, unifying approach that aims to sustainably balance and optimize the health of people, animals and ecosystems. It recognizes the health of humans, domestic and wild animals, plants, and the wider environment (including ecosystems) are closely linked and inter-dependent. OHHLEP, 2021 Source: OHHLEP (2021), p. 13

6. Global Health Approach Veterinary Health One Health Prioritises Human Health Prioritises Animal Health Co-Prioritises Human, Animal & Ecosystem Health Example 1 AMR tackled by limiting antimicrobial drug use in hospitals AMR in animals tackled by limiting antimicrobial use in livestock AMR in humans tackled by limiting animal drug use and environmental contamination; accounting for socio-ecological and cultural determinants of overuse. Example 2 Poor mental health among pastoralists attributed to low income Low income attributed to high mortality among livestock Poor mental health attributed to high rates of livestock disease and death, via loss of livelihoods

8. One Health High Level Expert Panel (OHHLEP) Established in 2021 after the quadripartite agreement between the WHO, WAOH, FAO, and UNEP Aim: to give guidance and inputs to enhance cross- sectoral collaboration within the quadripartite agreement to mainstream a One Health approach . Four areas of initial focus: One Health implementation Inventory of current knowledge in preventing emerging zoonoses Surveillance, early detection and rapid data sharing in prevention of emerging zoonoses Factors causing spillover and subsequent spread of diseases. ohhlep--one-health-theory-of- chance.pdf (who.int) One Health High-Level Expert Panel (OHHLEP) (who.int) An essential and primary priority was to develop a common definition of One Health Source: OHHLEP (2021), OHHLEP (2022)

9. One Healths Precedent in Indigenous Philosophies and Practices (1/2) The Indigenous Peoples of the Kalahari (Southern Africa) "are well- known for the profound connection with their land, intimate knowledge of the natural world, and delicate balance they have maintained for millennia with the environment." In the Andean and Amazonian Indigenous cultures, "Sumak kawsay, or good life in the Kichwa language, is an Indigenous principle promoting living in harmony with nature in order to achieve wellbeing for all." "Indigenous Peoples across Canada are unified in their belief that the wellbeing of an individual is directly connected to the wellbeing of the Land." Hillier et al. (2021) Survival International (2022) Pachamama (2022)

12. Alternative Integrated Health Paradigms Planetary health Ecohealth Human health is inextricably linked to the health of our planet and natural ecosystems, requiring environmental stewardship to tackle degraded planetary systems for human health. Strives to improve human and animal health through achieving healthier ecosystems. It increasingly adopts One Health and Conservation medicine under its remit. In this model, socio-ecological drivers of health are emphasised. Zinsstag (2013) Steffen et al. (2015) For a comparison of the three holistic approaches to health, see Lerner and Berg (2017)

15. Three Implementing One Health Implementing One Health Key competencies and principles

16. Paradigm shift: environmental stewardship and recognition of anthropogenic drivers System-thinking: holistic approach to understanding the problem Sociopolitical and multi-cultural parity: gender-responsive and human rights- based approaches Multi-sectoral and inter/trans- disciplinary responses: integrating diverse knowledge forms Underlying principles necessary to implement a One Health approach

17. Paradigm Shift The paradigm shift within One Health requires people to reconnect with indigenous ways of life and reduce the level of extraction and destruction by recognising that We are part of a complex, adaptive ecosystem Our health is directly dependent on ecosystems' health Our presence is more about belonging than conquering Our role is stewardship rather than ownership Work with the natural evolutionary and ecosystem processes to enhance life on earth, rather than exploit and degrade See the Roadmap to a One Health Agenda 2030 Image Source: Unknown via pxfuel

18. Systems Thinking: A key principle, but lacking implementation Developing an understanding of the workings of a system to better understand its purpose and predict its behaviour (and if necessary, how that can be influenced for the better). (Stroh, D. 2015, Arnold and Wade, 2015) Source: Hitziger, et al. (2021). An understanding of how complex systems behave, using a holistic approach (holism) that aims to include multiple perspectives (pluralism).

39. Food Safety Hazards One Health and Food Systems

40. Food Safety Hazards Agriculture, Nutrition, and Health (1/2) Food safety is an integral part of food security. Food security exists when all people, at all times, have physical and economic access to sufficient, safe and nutritious food that meets their dietary needs and food preferences for an active and healthy life. Hazards familiar to ANH researchers: Biological: Foodborne pathogens (including zoonotic e.g., Salmonella, E. coli, Campylobacter, brucella, etc., and antimicrobial resistant strains) Chemical: Mycotoxins, residues of pesticides or drugs, processing chemicals (addition/contamination) etc. Physical: Extraneous/foreign materials e.g., glass, plastic, metal etc. FAO (1996) Food safety hazards definition: Food safety hazards definition: biological, chemical, or physical agents in food, including allergens, or a condition of food with the potential to cause an adverse health effect. Hazards may be introduced at various stages from farm to fork, and risks vary between simple and industrialised food systems.

41. Food Safety Hazards One Health Lens on Campylobacter (2/2) Why Campylobacter spp.? Environment Climate change sensitive, heat stress increases shedding in birds, higher temperatures and humidity increase pathogen survival and replication rates, and vector prevalence, increased human transmission from leisure activities, risk of breaks in cold chain Most important foodborne zoonotic pathogen associated with poultry meat consumption What is it s OH significance? Poultry Humans Common intestinal bacteria, potential to cause diarrhoea, low impact on production, highly transmissible, flies as vectors between flocks, high risk of contamination in processing, AMR strains Acute gastro-intestinal disease, potential fatalities in young & elderly, contributes to environmental enteric dysfunction and stunting, neurological complications (Guillain-Barr Syndrome), cooking kills pathogen, risk contamination of uncooked foods in kitchen preparation. Where should interventions be implemented? Who should be responsible for them? Who bears the cost? Source: Zhang, Beyi & Yin. (2023).

42. Antimicrobial Resistance One Health and Food Systems

43. Antimicrobial Resistance - AMR (1/4) AMR occurs when any microorganism (fungi, bacteria, virus, parasite) develops resistance to know anti-microbial (anti-biotics, anti- fungal, antimalarials) treatments. AMR is proportional to the amount of antimicrobial used per person or livestock animal. Unregulated or excessive use in humans and livestock, aquaculture, and agriculture accelerates the emergence and transmission of AMR genes by exerting selective pressure on resistant strains. Public Health 5 million deaths in 2019; predicted to increase to 10 million by 2050 AMR infections cause increased spread to community Increased treatment cost and duration: AMR could cost from $300 billion to more than $3.4 trillion annually by 2050 worldwide. Increased morbidity and mortality of infectious disease Source: O'Neill (2016)

44. AMR In (animal-sourced) Food Systems (2/4) Animal food systems Contributing factor to the availability of cheap animal-sourced foods Used for growth promotion and disease prevention; secondarily used for disease treatment Poor animal welfare conditions increase the need for antimicrobials A lack of access to pathogen- and animal- specific antimicrobials contributes to poor welfare Alternatives to antimicrobials: vaccines, improved biosecurity, animal welfare, and nutrition Total antimicrobial consumption in animals in 228 countries is estimated at 63,151 tons. Projected to rise by 67% by 2030, and nearly 100% in Brazil, Russia, India, China, and South Africa (Van Boeckel, 2010).

45. AMR In the Environment (3/4) Environment Antimicrobial pollution from pharmaceutical production, agricultural run-off, livestock manure for fertilizer, and human waste Large volumes enter waterways and other ecosystem Exposes a wide range of microorganisms to antimicrobial-resistant genetic material increasing the likelihood of AMR emergence Horizontal gene transfer occurs environmentally Image Source: Walsh (2018)

46. AMR - Management (4/4) How do we ensure antibiotic access for humans and livestock whilst reducing the drivers of AMR emergence? Managing AMR requires: A One Health approach considers the following: Biosecurity Surveillance Drug research and discovery Drugs tailored to specific pathogens to prevent overuse Improved animal welfare Regulation of pharmaceutical production, waste management, and sales Tackle the core problem: excessive and non- specific use Access for public health, food security, and ecosystem health Decision-making processes Actions across temporal and geographical scales Inter/Trans-disciplinary

47. Environment and Health One Health and Food Systems

48. Environment and Health - Climate Change (1/2) Two-fold: climate change changes disease transmission patterns and investments in irrigation for livestock under food systems transformations in low- and lower-middle income countries increase the risk of vector-borne diseases, such as malaria. The global food system is responsible for up to 30% of total green-house gas emissions -IPCC 2019 Source: Sadie J. Ryan et al. 2019

49. Environment and Health - Biodiversity Loss (2/2) The links between Agriculture and Biodiversity loss How does this relate to disease emergence? 69% biodiversity decline since 1970, primarily driven by land-use change for agricultural production. Increased likelihood of communicable disease at the wildlife-livestock-human interface: abundance of reservoirs host species in human-dominated landscapes relative to biodiverse ecosystems. WWF (2022) Keesing and Ostfeld, (2021) Increased likelihood of non- communicable disease: homogenization of diets, reduced crop yields, increased reliance on fewer crop and animal species for food provisioning Nitrogen-rich nutrient run-off from aquaculture and terrestrial agriculture cause eutrophication and lethal algal blooms contributing to biodiversity loss Keesing and Ostfeld, (2021) NRDC (2021)
