One Health.
One Shared Future.

One Health illustration connecting people, animals, plants and the environment

Human, animal, plant and environmental health are deeply connected. One Health brings these relationships together to support healthier people, resilient ecosystems and a more sustainable shared future.

One Health

Health does not exist in separate boxes. The wellbeing of people is closely linked to animals, plants, food systems and the ecosystems that support them.

One Health is an integrated approach that recognizes these connections and encourages different disciplines and sectors to work together. Instead of addressing human, animal, plant and environmental health as isolated subjects, it looks at how changes in one part of the system can influence the others.

This perspective is increasingly important in a world shaped by changing climates, expanding food systems, biodiversity loss, antimicrobial resistance, pollution and emerging infectious diseases.

One Health Connections

One Health brings several closely connected areas into the same scientific and practical conversation.

👥

Human Health

Public health, nutrition, infectious disease, healthy communities and access to safe food, water and environments.

🐾

Animal Health

Livestock, wildlife and companion-animal health, including diseases and risks shared across species.

🌱

Plant Health

Healthy crops, forests and vegetation that support food security, biodiversity, livelihoods and resilient landscapes.

🌍

Environmental Health

Soil, water, air, climate and biodiversity—the environmental foundations on which human, animal and plant health depend.

Why One Health Matters

Many important health challenges arise where people, animals, plants and the environment interact. A change in land use can alter wildlife contact. Water quality can affect food safety. Antimicrobial use in different sectors can contribute to resistance across connected systems. Climate and ecosystem change can shift the conditions in which vectors and pathogens spread.

One Health helps make these relationships visible. It supports shared surveillance, prevention, research, education and coordinated action before a problem becomes harder to manage.

Challenges We Share

No single discipline can address every connected health challenge. One Health provides a framework for working across boundaries.

Zoonotic & vector-borne diseases Understanding disease pathways among wildlife, livestock, people and vectors.
Antimicrobial resistance Connecting antimicrobial use and resistance across medicine, animals, agriculture and the environment.
Food & water safety Protecting health across production, processing, consumption and environmental pathways.
Climate & ecosystem change Understanding how environmental change reshapes disease risk, food systems and community resilience.
Food security & sustainable agriculture Supporting productive agriculture while protecting soil, water, plants, animals and human wellbeing.
Pollution & environmental health Linking environmental exposures with the health of people, animals, plants and ecosystems.

The SAFE Society Approach

The SAFE Society uses One Health as a bridge between scientific disciplines and between science and society. Agriculture, food security, soil and environmental health, animal health and human wellbeing are treated as connected parts of a shared system.

01
Research & scientific exchange Connecting researchers across soil, plant, animal, environmental and human-health disciplines.
02
Education & capacity building Supporting seminars, training, scientific communication and opportunities for students and professionals.
03
Regional & community collaboration Using regional chapters and networks to connect One Health with local priorities and institutions.
04
Evidence-to-action dialogue Encouraging communication among researchers, practitioners, communities and decision-makers.

From Science to Action

Connect

Bring together disciplines, sectors, regions and communities that often work separately.

Understand

Study the full system—its biological, environmental, agricultural and social relationships.

Act

Translate shared evidence into prevention, education, collaboration, policy dialogue and resilient practice.

Get Involved

One Health needs more than one discipline.

Researchers, students, practitioners, educators and collaborators can all contribute to healthier people, healthier ecosystems and a more resilient shared future.

Join SAFE
Scientific framing follows the widely used One Health concept described by the World Health Organization and the FAO–UNEP–WHO–WOAH One Health collaboration.
