How can One Health’s integrative view of human–animal–environment relations meet Planetary Health’s concern with Earth-system change and justice? This session brings both communities together with colleagues from related fields to examine shared concepts, expose frictions, and explore methods beyond the binaries of healthy/unhealthy and human/nature.

We invite short contributions linking (public) health, veterinary and environmental sciences with social sciences, design, and policy. Topics may include human–environment conflicts, urbanization, pollution, and multispecies health, food systems, zoonoses/AMR, and planetary boundaries, or address the potentials of planetary thinking for conceptualizations of health and ill-being, as much as their shifting spatial and temporal scales. 

Work that foregrounds power and inequality, plural cosmologies, and co-production with communities is especially encouraged.

Format: lightning talks plus a moderated exchange to map convergences, disagreements, and blind spots, and to sketch a research and action agenda for BUA Grand Challenges and partners. Contributions may be empirical, theoretical, or practice-based (quantitative, qualitative, mixed, participatory). Please state the problem, approach, key insight or hypothesis, and implications for collaboration or contestation across One Health, Planetary Health, and allied fields.
