One health policy

Most emerging infectious diseases in people come from animals, and antimicrobial resistance spreads between people, animals and the environment. One Health is the approach that links human, animal, plant and environmental health governance so that threats are detected and prevented where they begin. This page sets out how One Health policy works and fails, the records that show it, and the institutions that decide.

01In brief

The short answer.

One Health policy is the coordination of human, animal, plant and environmental health governance to prevent and detect shared threats such as zoonoses and antimicrobial resistance. It needs joint surveillance, mechanisms and budgets across ministries. Health, agriculture and environment ministries and veterinary services hold the decisions.

04The question

One health policy: how the risk develops.

Cross-sector stewardship and coordination. The dossier below sets out how the risk develops, what is measured, where the data come from, how it is modelled and who decides.

Mechanism

Spillover begins at interfaces

Land-use change, wildlife trade and intensive livestock bring people and animals into closer contact. Pathogens cross where these interfaces are least monitored.

Mechanism

Sectors work apart

Health, agriculture and environment ministries have separate laws, budgets and surveillance systems. Without joint mechanisms, signals in animals do not reach human health authorities in time.

Mechanism

Antimicrobials select resistance

Antibiotic use in human medicine, livestock and aquaculture selects resistant bacteria that move between sectors through food, water and contact.

Mechanism

Prevention is underfunded

Preventing spillover produces no visible event, so it competes poorly for funds against response. Benefits fall across sectors that do not share budgets.

05Key terms

Terms used on this page.

Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.

TermDefinition
ZoonosisAn infectious disease that has jumped from an animal to people.
SpilloverThe transmission of a pathogen from one host species, often wildlife or livestock, to another such as humans.
Antimicrobial resistanceThe ability of microorganisms to survive medicines that once killed them or stopped their growth.
06Indicators

What is measured, and how well.

Each indicator carries its unit, its cadence, the kind of source behind it and the evidence label a value would carry. No values are shown: a programme supplies them under its own authority.

07Canvas

From sources to decisions.

The topic as a computational graph: named sources feed the methods, an evidence review gates the outputs, and the decisions stay with the authorities that hold them.

Pipeline canvas · One health policy as a run graphDesign, not a record
One health policy: event detection, verification and notificationIndicator-based and event-based signals are triaged and verified; the national focal point assesses the event with the Annex 2 decision instrument and notifies within 24 hours when it qualifies; response and after-action review follow.

10Core questions

What experts ask.

The questions concern coordination without merging mandates.

  • Which agencies hold responsibility for zoonoses, antimicrobial resistance, food safety and environmental contamination?
  • Is there a formal mechanism, such as a joint committee or legal duty, for them to coordinate?
  • How is surveillance data shared between human, animal and environmental sectors?
  • How are joint priorities funded when budgets are sectoral?
  • How are farmers, communities and Indigenous knowledge holders involved?
11Mechanisms

Mechanisms and drivers.

Sectoral organization is the main obstacle. Each agency answers to its own minister and legislation and measures success differently. Coordination often depends on individuals and lapses when they move. Formal mechanisms, joint plans and shared data platforms make cooperation more durable.

International organizations covering human health, animal health, food and agriculture, and the environment have committed to joint One Health work, and many countries have national action plans, particularly on antimicrobial resistance. Implementation varies widely with resources and political priority.

14Questions

Questions and answers.

What is One Health?
An integrated approach that aims to balance and optimise the health of people, animals and ecosystems, recognising that they are linked and interdependent, as the One Health High-Level Expert Panel defines it.
Who are the Quadripartite?
FAO, UNEP, WHO and the World Organisation for Animal Health, which coordinate One Health work through a joint plan of action.
Why is antimicrobial resistance a One Health problem?
Because resistant bacteria and resistance genes move between people, animals, food and the environment, so use in one sector affects risk in the others.
Why is One Health hard to put into practice?
Because it asks agencies with different laws, budgets and priorities to share information and act together. Without formal mechanisms and funding, coordination tends to fade.
Is antimicrobial resistance a One Health issue?
Yes. Resistance develops and spreads across human medicine, agriculture and the environment, so effective action requires all three sectors.
What does a working One Health mechanism look like?
Typically a standing body with representatives from human, animal and environmental health, a legal or policy mandate, a shared work plan with its own budget, agreed rules for sharing surveillance data and regular joint exercises. Its value shows in routine work, not only in emergencies.
Does the platform coordinate national agencies?
No. It convenes and compares. Coordination is the responsibility of national governments and their agencies.
