Dr. Tia Kansara is a globally recognized authority on regenerative systems, planetary health, and the built environment, whose work sits at the intersection of human longevity and the design of the spaces we inhabit. She is the CEO of Replenish Earth, a UN Special Advisor, and an internationally sought-after keynote speaker on regenerative systems, ESG, and planetary health.

With more than two decades advising governments, Fortune 500 companies, and global institutions, Tia has dedicated her career to a single, integrative question: how do we design human systems—buildings, cities, organizations, and bodies—that actively replenish life rather than deplete it? Her work bridges science, policy, and lived human experience, translating complex research on physiology, ecology, and sustainability into frameworks that decision-makers can act on. It is this lens she brings to her chapter on Human, Animal, and Planetary Flourishing in Urban Systems, where she argues that the longevity of any one species in a city is inseparable from the longevity of all the others.

In April 2026, Tia formally introduced Nervous System Compliant™ (NSC™) Design, a new built-environment standard nearly two decades in the making. NSC™ measures the impact of spaces on the human autonomic nervous system across six dimensions—sympathetic activation, circadian coherence, sensory layering, biotic contact, social neurophysiology, and interoceptive safety—offering the longevity field a rigorous, body-based language for how environments shape healthspan. The standard sits inside her wider Replenish Earth™ and N+™ frameworks for regenerative design.

A Ph.D.-trained researcher, Honorary Fellow of the Royal Institute of British Architects (Hon FRIBA), and certified Trauma-Informed Somatic Practitioner, Tia brings an unusually wide aperture to longevity science—pairing planetary-scale systems thinking with the granular biology of how a single human body responds to light, materials, sound, and social space.

Based in London, she continues to advise leaders worldwide on how to build environments, institutions, and lives capable of carrying the next century of human, animal, and planetary flourishing.
