One Health is the idea that the health of people, animals, plants and the environment are deeply connected.
It recognises that humans do not live separate from nature. We live within ecosystems. The food we eat, the animals we keep, the soils we farm, the water we drink, the air we breathe and the landscapes around us all influence our health.
At its simplest, One Health says:
Human health, animal health and ecosystem health are linked — and we need to care for them together.
This idea is becoming increasingly important as the world faces climate change, biodiversity loss, soil degradation, antimicrobial resistance, pollution, food insecurity and emerging diseases. These are not isolated problems. They overlap.
A disease that begins in animals can affect humans. Poor soil can affect food quality. Polluted water can harm wildlife, livestock and people. Intensive farming practices can affect animal welfare, antibiotic use, ecosystems and public health. Climate change can change where pests and diseases spread.
One Health gives us a way to think about these connections.
For regenerative farming, agroecology and sustainable food systems, One Health is especially useful. It helps explain why healthy soil, healthy animals, healthy food, healthy people and healthy landscapes belong in the same conversation.
One Health is a collaborative approach to health that recognises the connections between humans, animals, plants and ecosystems.
Instead of treating human health, veterinary health, farming, food systems and environmental protection as separate issues, One Health brings them together.
A One Health approach asks questions such as:
One Health is not just about medicine. It is about relationships.
It recognises that health is not created only in hospitals or clinics. Health is also created in fields, farms, forests, rivers, homes, food systems and communities.
Which is quite a lot for one phrase to carry, but it does a decent job.
A simple definition of One Health is:
One Health is an approach that recognises that the health of humans, animals and the environment are interconnected and should be protected together.
The World Health Organization describes One Health as an integrated, unifying approach that aims to sustainably balance and optimise the health of people, animals and ecosystems.
In practical terms, One Health means different sectors working together, including:
This joined-up thinking is important because many modern health challenges do not fit neatly into one box.
A river polluted by agricultural runoff is not only an environmental issue. It may also be a farming issue, a public health issue, a wildlife issue, a drinking water issue and a community wellbeing issue.
One Health helps us stop pretending these boxes are separate.
One Health matters because many of the biggest challenges we face are connected.
We cannot solve them properly if we only look at one piece of the puzzle.
Some infectious diseases can pass between animals and humans. These are called zoonotic diseases.
Examples include diseases associated with wildlife, livestock, pets or insects such as ticks and mosquitoes.
The risk of disease spillover can be affected by:
One Health does not mean blaming animals for disease. It means understanding that disease risk is shaped by the way humans interact with animals and ecosystems.
When habitats are damaged, wildlife is stressed, livestock systems are crowded, or ecosystems are simplified, disease dynamics can change.
Healthy ecosystems can help regulate disease risks. Degraded ecosystems can sometimes increase them.
Antimicrobial resistance happens when bacteria, viruses, fungi or parasites evolve so that medicines no longer work effectively against them.
Antibiotic resistance is one of the best-known examples.
This is a One Health issue because antibiotics are used in both humans and animals. Resistant bacteria or resistance genes can move between people, animals, food, water, soil and the environment.
Antimicrobial resistance can be influenced by:
A One Health approach encourages responsible antibiotic use, good animal husbandry, better hygiene, disease prevention, improved welfare and environmental protection.
In farming, healthier animals in lower-stress systems may need fewer routine treatments. That is good for animals, farmers and public health.
Food is one of the clearest links between people, animals and ecosystems.
The way food is grown affects:
Modern food systems can produce large amounts of calories, but they can also contribute to poor diets, ultra-processed food dependence, soil degradation, biodiversity loss and unfair farmer incomes.
One Health encourages us to think about food more holistically.
A healthy food system should:
A packet of food is never just a packet of food. It carries a whole landscape behind it.
Soil is often missing from public health conversations, which is a shame because soil is doing a lot of heavy lifting.
Healthy soil supports:
Degraded soil can contribute to:
Soil also contains vast microbial life. Scientists are increasingly interested in how soil microbiomes, plant microbiomes, animal microbiomes and human microbiomes may be connected.
This does not mean soil is automatically safe or magical. Soil can also contain contaminants, pathogens or pollutants. But healthy, well-managed soil is one of the foundations of human health.
No soil, no food. No food, no humans. Soil wins the argument quite quickly.
One Health includes animal health and welfare.
Animals kept in poor conditions may be more stressed, more vulnerable to disease and more likely to require routine medication. This can affect farmers, food systems, disease risk and antimicrobial use.
Good animal welfare can support:
This applies to livestock, companion animals and wildlife.
In regenerative farming, good animal welfare might include:
Animal health is not separate from land health. A cow standing in a treeless field during a heatwave is not just an animal welfare issue; it is a design issue.
Biodiversity is the variety of life, from soil microbes and insects to birds, mammals, plants and fungi.
Biodiversity supports human health by providing:
When biodiversity declines, ecosystems become less resilient.
For farming, biodiversity can reduce reliance on external inputs by supporting natural pest predators, pollinators, nutrient cycling and soil structure.
For people, biodiverse landscapes can support mental health, recreation, food security and cleaner environments.
A One Health approach recognises biodiversity as part of the health system, not as decoration.
Climate change affects people, animals, plants and ecosystems at the same time.
It can lead to:
One Health is useful because climate change is not only an environmental problem. It is a health problem, a food problem, an animal welfare problem, a farming problem and a justice problem.
Regenerative and agroecological farming can contribute to climate resilience by:
These practices do not solve climate change alone, but they help build healthier systems that can cope better with shocks.
Regenerative farming fits naturally within a One Health framework.
Regenerative agriculture aims to improve the living systems that food production depends on. It focuses on soil, water, biodiversity, animals, carbon, plants and farm resilience.
A regenerative approach supports One Health by:
For example, planting trees in a silvopasture system can provide shade for livestock, improve animal welfare, support birds and insects, store carbon, reduce wind, improve water infiltration and create future farm products.
That is One Health in action. One intervention, many benefits.
Agroecology also fits closely with One Health.
Agroecology applies ecological principles to farming and food systems. It includes soil health, biodiversity, farmer knowledge, local food networks, social justice and food sovereignty.
A One Health lens helps show why agroecology matters.
Agroecology can support:
Agroecology is especially useful because it does not stop at the farm gate. It asks how food systems can better serve people and ecosystems together.
Human health is not only about individual choices. It is also shaped by food access, land use, farming policy, income, culture and community.
A farm improves housing, pasture access, nutrition, hygiene and breeding choices. Animals become healthier and disease pressure drops.
This can reduce the need for antibiotics, supporting animal welfare and helping reduce antimicrobial resistance risks.
A farmer plants trees and vegetation along a stream.
This can reduce runoff, protect water quality, support wildlife, shade the stream, reduce flooding and improve the farm landscape.
People, animals and ecosystems all benefit.
A grower uses compost, cover crops, reduced tillage and diverse rotations.
This improves soil structure, supports microbes, reduces erosion, helps plants access nutrients and protects water.
Healthy soil supports healthier crops and more resilient food production.
A community-supported agriculture project grows food using agroecological practices and sells directly to local households.
This can support healthy diets, farmer livelihoods, food education, soil health and community connection.
Trees are planted into pasture.
Livestock gain shade and shelter, pasture becomes more resilient, biodiversity increases and carbon is stored.
Again: one action, many layers of health.
One Health is closely connected to the conversation about nutrient-dense food.
Human nutrition depends on farming systems, soil health, crop diversity, livestock management, food processing and access.
A One Health approach asks:
Healthy food is not only about nutrients on a label. It is about the whole system that creates that food.
Regenerative and agroecological farming may support nutrient density by improving soil biology, plant diversity and ecological function, although the science is still developing and should be discussed carefully.
What is clear is that healthy food systems depend on healthy ecosystems.
One Health also includes the less obvious connections between landscape and wellbeing.
Access to green spaces, gardens, farms, woodlands and nature can support mental health, physical activity, social connection and a sense of purpose.
Farming communities also need support. Farmer mental health is affected by financial pressure, climate stress, isolation, policy changes and workload.
A truly One Health approach should care about:
Health is not only the absence of disease. It is the presence of conditions that allow life to flourish.
That sentence sounds grand, but honestly, it earns it.
One Health is powerful, but it is not always easy to apply.
Different sectors work separately: Doctors, vets, farmers, ecologists and policymakers often operate in different systems with different language, funding and priorities.
Benefits can be hard to measure: A hedgerow may support birds, reduce wind, improve soil moisture, store carbon and benefit mental wellbeing. But measuring all of that neatly is difficult.
Short-term economics can block long-term health: Practices that improve soil, biodiversity or animal welfare may take time to pay back. Farmers need support during transitions.
Responsibility can be uneven: Consumers are often told to make better choices, but many food system problems are structural. Policy, supply chains, supermarkets, land access and pricing all matter.
The term can become vague: Like many good ideas, One Health can become a slogan if not linked to real action.
A strong One Health approach needs practical changes, collaboration and accountability.
Farmers and growers can support One Health by making decisions that benefit soil, animals, people and ecosystems together.
Practical steps include:
Not every farm can do everything at once. Start with changes that fit the land, business and people involved.
One Health is not about perfection. It is about connection.
Consumers can also support One Health through food and lifestyle choices, where they have the means to do so.
Helpful actions include:
It is important not to make this all about individual consumer responsibility. Many people do not have equal access to healthy, ethical or local food.
That is why One Health also needs policy, fair markets and food justice.
The future of food cannot only be about producing more.
It must be about producing food in ways that support health across the whole system.
That means asking:
One Health helps bring these questions together.
It shows that public health is not separate from farming. Farming is not separate from ecology. Ecology is not separate from food. Food is not separate from culture and justice.
Everything is connected. Which is inconvenient if you like simple answers, but very useful if you want real ones.
One Health is the recognition that the health of humans, animals, plants and ecosystems is interconnected.
It matters because the biggest challenges we face — disease, antimicrobial resistance, climate change, biodiversity loss, soil degradation, food insecurity and poor diets — are connected too.
For regenerative farming and agroecology, One Health provides a powerful framework. It helps explain why soil health, animal welfare, biodiversity, water quality, nutrient-dense food, local food systems and human wellbeing should not be treated as separate issues.
A healthy future depends on healthy relationships: between people and land, animals and ecosystems, food and soil, farms and communities.
One Health reminds us that caring for nature is not separate from caring for ourselves.
It is one of the most practical forms of healthcare we have.

Useful for: overview, disease emergence, wildlife-livestock-human interfaces, further reading.
Research and policy around One Health increasingly shows that human wellbeing cannot be separated from animal health, soil health, biodiversity, food systems and the wider environment. Reports from WHO, FAO, UNEP and WOAH define One Health as an integrated approach to balancing the health of people, animals, plants and ecosystems. Recent research also connects One Health to soil restoration, nutrient-dense food, antimicrobial resistance, zoonotic disease risk, biodiversity loss and climate resilience. For regenerative farming and agroecology, this means soil health, animal welfare, clean water, diverse diets and ecosystem restoration are not separate goals — they are all part of the same living system.
