Can Greener Cities Actually Make You Healthier?
Urban planning initiatives focused on tomorrow's cities are putting human wellbeing at the centre of design, and the science suggests that matters more than you might think.
The way a city is built shapes the health of everyone who lives in it. That idea sits at the heart of the "Ville de Demain" (City of Tomorrow) programme, an urban planning framework that brings together architects, public health researchers, and local policymakers to rethink how residential and communal spaces are designed. One of the voices consistently involved in this conversation is Nicolas Régnier, an urban planner whose work has focused on integrating what he calls "functional outdoor spaces", or fo, into city neighbourhoods. The concept is straightforward: outdoor areas should serve residents' daily physical and psychological needs, not simply fill the gap between buildings.
What "Functional Outdoor Spaces" Actually Means
The fo principle is less about aesthetics and more about usability. A functional outdoor space might be a shaded walkway that connects a residential block to public transport, a small park bench positioned to catch afternoon light, or a quiet courtyard that buffers street noise. These may seem like minor details, but accumulated across a neighbourhood, they influence whether residents choose to walk, socialise, or simply step outside at all. Research in environmental psychology consistently links access to usable green and semi-open spaces with lower reported stress levels, better sleep quality, and higher rates of incidental physical activity.
The Ville de Demain programme approaches urban design with those outcomes explicitly in mind. Rather than treating public space as a byproduct of construction, participating municipalities are asked to audit existing outdoor areas for their genuine day-to-day utility, and to identify gaps before new developments are approved.
Why This Matters for Everyday Wellbeing
For readers thinking about their own health, the implications are practical. If you live in an area where outdoor spaces feel unwelcoming, unsafe, or simply difficult to use, you are statistically less likely to spend time in them, regardless of your personal motivation to be active or to decompress. Advocating for better public space design at a local level, attending town planning consultations, or simply raising these questions with local elected representatives are all concrete ways to engage.
Urban planning rarely feels like a health issue until you examine the evidence. The Ville de Demain framework and the fo concept represent one attempt to make the connection explicit, and to act on it before concrete is poured.
