What if we measured progress not by economic growth, but by the health of people, nature, and the ecosystems that sustain us?

In the 7th Villars Institute Distinguished Lecture, Dr. Soumya Swaminathan—former Chief Scientist of the World Health Organization (WHO) and Chair of the M.S. Swaminathan Research Foundation—introduces the concept of biohappiness: a holistic vision of wellbeing that places ecology, health, equity, and sustainability at the heart of development.

Drawing on decades of experience in global public health and sustainable development, Dr. Swaminathan explores why the world's most pressing challenges—from climate change and biodiversity loss to food insecurity, air pollution, inequality, and pandemic preparedness—cannot be solved in isolation. Instead, they require systems thinking and integrated solutions that recognize the deep connections between human health and the health of the planet.

This lecture challenges conventional measures of progress such as GDP and makes the case for a new framework—one that values environmental resilience, social wellbeing, sustainable livelihoods, and shared prosperity.

For anyone interested in the future of public health, sustainability, climate action, and global development, this lecture offers an inspiring and practical vision for building a more equitable and resilient world.
