The book "One Health, Eco-health, and Planetary Health Perspective" is an integrative academic text that synthesizes three critical, evolving frameworks for understanding global health. It transcends traditional disciplinary silos by examining the inseparable connections between human health, animal health, and the integrity of ecosystems, all under the overarching pressures of global environmental change. Its core aim is to articulate a coherent, unified vision that leverages the strengths of each approach—One Health’s operational focus on zoonoses and antimicrobial resistance, Eco-health’s emphasis on socio-ecological systems and participation, and Planetary Health’s macro-scale analysis of anthropogenic disruption to Earth’s natural systems.

This book makes a pivotal contribution to the literature by moving beyond comparative analysis to propose a synergistic, transdisciplinary paradigm. It fills a significant gap by providing a consolidated intellectual foundation and practical roadmap for researchers, policymakers, and practitioners. The various chapters advance the discourse by arguing that these are not competing but complementary lenses, all essential for addressing complex challenges like pandemics, biodiversity loss, and climate change. It thus serves as a seminal call for holistic governance and research, pushing the literature toward greater integration and actionable strategies for securing the health of all species and the biosphere.
