Recently, I had the privilege of catching up with an old colleague, Professor Razita Sham, who has been appointed as a Professor in the Kulliyyah of Medicine, International Islamic University Malaysia (IIUM). Prof Razita, who is retiring from UNIMAS, and I share a professional history. Although she is more senior than I am, we completed our public health training together at UKM from 1999 to 2003.
Currently, she serves as a short-term consultant for WHO, focusing particularly on One Health. At IIUM, she has been appointed to help with the implementation of the Master of Public Health (MPH) and Doctor of Public Health (DrPH) programmes. Meanwhile, I have been appointed as part of an expert group working on integrating planetary health into higher education, a role I am deeply passionate about.
During our discussion, we delved into the concepts of planetary health and One Health, which seem to be increasingly interconnected in global health discourse. Prof Razita shared an insightful perspective that resonates with me—she sees One Health as a process or approach, and planetary health as the ultimate outcome.
This conceptualisation makes sense. One Health provides a structured, actionable framework. Originating with a focus on food security, it has since expanded to address complex challenges such as zoonosis, where Prof Razita is currently contributing by developing an action plan. One Health’s strength lies in its ability to bring together human, animal, and environmental health experts to address interconnected health issues.
Planetary health, on the other hand, broadens the focus, encompassing the health of the Earth as a system, where human well-being is inextricably tied to the sustainability of natural systems. It represents the ultimate goal—a thriving planet that supports all forms of life, addressing not just zoonotic diseases but also climate change, environmental degradation, and inequities in global health.
While One Health provides clear, actionable steps, planetary health offers a vision of where those actions should lead us. Both are vital in today’s world, where challenges transcend traditional disciplinary boundaries. By integrating these approaches into education and action, we can ensure that the next generation of health professionals and policymakers is prepared to address these global challenges.
My conversation with Prof Razita left me inspired. It reinforced the importance of collaboration, not just across disciplines but also among those working on interconnected frameworks. As we move forward, aligning processes like One Health with outcomes like planetary health is essential for building a healthier, more sustainable future.
It was a pleasant and unexpected meeting, one that reminded me of how far we have come since our training days at UKM, and how much there is still to learn from one another as we navigate the evolving landscape of public and planetary health.
