Agriculture and food are at the heart of interconnected challenges including the depletion of natural resources, pollution, the erosion of biodiversity, climate change, an increase in chronic and infectious diseases. New, integrative health-based approaches are needed to move beyond ‘siloed’ approaches that fail to consider the multiple interdependencies between human, animal and environmental health. However, existing approaches to health mostly deal with disease vectors and the impacts of the environment on human health. We propose to enrich the One Health concept based on the interdependencies between human, animal and environmental health by distinguishing between agroecosystems (local scale) and global ecosystems (land, water, the atmosphere, biocenoses). In this way, it is possible to explicitly address relationships between the food system, from field to diet, and the four domains of health, and thus to think about the changes to be made to meet contemporary local and planetary challenges.
