One Health

Partnering and investing in One Health

One Health is an integrated approach to preventing and responding to health threats at the human-animal-environment interface. It recognizes that the health of humans, animals, plants, and the environment are interconnected, and that a One Health approach is essential to protect the health of all.

One Health is a holistic approach to health that requires everyone to work together, including governments, international organizations, civil society, and the private sector. 

FAO works continually to support Members to promote health for people, animals, plants and the environment in a balanced and sustainable way. This includes measures focusing on infectious animal and zoonotic diseases, such as disease prevention, detection and control, but also the mitigation and management of antimicrobial resistance and efforts to achieve equity, stewardship, and sustainable development.

Partnering with FAO  

Some of FAO's One Health funding is provided through the One Health in Agrifood System Transformation Fund – a pooled multipartner mechanism supporting FAO's One Health Priority Programme Area. The fund offers an integrated and comprehensive One Health support package to countries to progress national pathways for transforming agrifood systems through One Health assessments and planning, technical support, policy advice and leveraging investment.

Partnering with the Quadripartite

To ensure a multisectoral approach to One Health, FAO partners with UNEP, WHO and WOAH (the Quadripartite) through the Quadripartite One Health Joint Plan of Action and works on joint initiatives and pooled funding mechanisms.

National One Health investment plans  

FAO, together with the Quadripartite, has been assisting pilot countries, Kenya and Senegal, with One Health prioritization and investment planning.   

National partnerships for One Health investments ideally involve co-investment from the government and also public-private partnerships, farmer cooperative groups and academia.
