The Guide to implement the One Health Joint Plan of Action (OH JPA) at national
level has been developed collaboratively by the four Quadripartite organizations, the Food
and Agriculture Organization of the United Nations (FAO), the United Nations
Environment Programme (UNEP), the World Organisation for Animal Health (WOAH),
and the World Health Organization (WHO).

The Guide is complementary to the OH JPA, which was launched in October 2022 in
response to international requests to prevent future pandemics and to promote health
sustainably through the One Health approach. Thus the Guide serves as an operational
addendum to OH JPA, translating the objectives and high-level activities described in the
OH JPA into national level context.

The purpose of this Guide is to provide countries with countries with practical guidance
on how to implement the One Health approach through the adoption and adaptation of the
OH JPA, aligning with the three pathways of the theory of change. The Guide has an
inclusive scope to allow every country to use it, regardless of its status with respect to One
Health development and implementation.
