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. A One Health approach is also critical for achieving the Sustainable Development Goals.
