EcoHealth and One Health: A theory-focused review in response to calls for convergence

EcoHealth and One Health are two major approaches broadly aimed at understanding the links between human, animal, and environment health. We aimed to gain a more in-depth understanding of the ontological, epistemological and methodological underpinnings of EcoHealth and One Health in order to identify areas of difference and overlap, and consider the extent to which closer convergence between the two may be possible.
