This chapter explores the intersections and distinctions between One Health, EcoHealth, and Planetary Health: three leading interdisciplinary approaches to global health. While aligned in their holistic focus on human, animal, and environmental health, these paradigms differ in scope, priorities, and their influence on legal frameworks. Recent efforts to merge these approaches offer practical benefits but raise critical questions about their individual contributions and legal implications.
The chapter examines three key areas: (1) the similarities and differences in how these approaches advocate for legal inclusion and reform, (2) how each approach frames its initiatives in relation to the others, and (3) the impact of these paradigms on existing national and international laws.
By analysing these paradigms’ contributions, the chapter highlights how One Health can learn from EcoHealth and Planetary Health to better integrate into legal systems. This comparative study underscores opportunities for these approaches to complement each other, advancing innovative, sustainable, and equitable frameworks for addressing global health challenges.
