Soil health is a critical focus for both One Health and Planetary Health initiatives. These frameworks recognize that current agricultural practices are causing environmental changes with negative human health impacts, including climate change, deforestation, and the emergence of zoonotic diseases and antimicrobial resistance. However, the training of health professionals typically does not include aspects of soil health. Understanding soil health and its relationship to agricultural practices could be foundational to addressing issues like antimicrobial resistance, zoonotic disease, food security, and climate change. A global focus on soil health offers opportunities for preventive interventions and convergence between One Health and Planetary Health approaches. Soil health is defined as the continued capacity of soil to function as a living ecosystem that sustains plants, animals, and humans. It is reflected in the physical, chemical, and biological state of soil and is supported by soil organic matter and soil life. Soil health is essential for nutrient cycling, carbon sequestration, and limiting pathogen opportunities. Regenerative agriculture, which minimizes soil disturbance, builds soil organic matter, and promotes crop diversity, is a key approach to improving soil health. Regenerative agriculture practices can reduce exposure to human pathogens and antimicrobial resistant bacteria through composting and other soil-building methods. These practices also contribute to reducing agricultural emissions, improving food quality, and supporting rural livelihoods. The integration of livestock with crop production and the use of diverse crop rotations and cover crops enhance soil biodiversity and resilience. Soil health is fundamental to ecosystem and human health. Biodiverse soil ecosystems support aboveground biodiversity and healthy human communities. Regenerative practices that build soil health and biodiversity can address "wicked problems" relevant to both One Health and Planetary Health. Incorporating soil health principles into health professional training and research initiatives could enhance interventions in agriculture and medicine. Overall, soil health is a key component of sustainable agriculture and planetary health.Soil health is a critical focus for both One Health and Planetary Health initiatives.
