One Health is an integrated, unifying approach that aims to sustainably balance and optimize the health of people, plants, animals and ecosystems.

FAO promotes a One Health approach as part of agrifood system transformation for the health of people, animals, plants and the environment. This involves a spectrum of actors and work on sustainable agriculture, animal, plant, forest, and aquaculture health, food safety, antimicrobial resistance (AMR), food security, nutrition and livelihoods.

Ensuring a One Health approach is essential for progress to anticipate, prevent, detect and control diseases that spread between animals and humans, tackle AMR, ensure food safety, prevent environment-related human and animal health threats, as well as combatting many other challenges.

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.

The approach mobilizes multiple sectors, disciplines and communities at varying levels of society to work together to foster well-being and tackle threats to health and ecosystems, while addressing the collective need for clean water, energy and air, safe and nutritious food, taking action on climate change, and contributing to sustainable development.
