At the One Health Summit held in Lyon on 7 April 2026, the Quadripartite collaboration, bringing together the Food and Agriculture Organization of the United Nations (FAO), the United Nations Environment Programme (UNEP), the World Health Organization (WHO) and the World Organisation for Animal Health (WOAH), joined global leaders and partners in calling for strengthened investment and partnership, and accelerated country-level implementation of the One Health approach. 

Against a backdrop of converging crisis, including climate pressures, pollution, environmental degradation and growing strain on food systems, and increasing risks to animal health, contributing to the acceleration of health threats and pandemic risk, the Summit, hosted by France, emphasized that stronger political commitment and coordinated multilateral action are critical to safeguard the health of humans, animals and ecosystems alike.
