ETH Zurich at WUF13: From the Global Housing Crisis to Local Systemic Alternatives

Fernando Túlio Franco — Thu, 25 Jun 2026 08:00:00 +0000

The world is in the grip of a housing crisis of historic proportions. The World Cities Report 2026 (UN-Habitat), launched at the World Urban Forum 13 (WUF13) earlier in May this year, left us genuinely struck by the scale: 3.4 billion people lack adequate housing, the global deficit grew from 251 to 288 million units between 2010 and 2023, and climate hazards could destroy 167 million more homes by 2040. Yet what moved us equally was seeing, across five days of the forum, the breadth of local solutions from every region of the world, approaches grounded in community, place and governance, yet pointing toward the same conclusion: that this crisis demands systemic change, not just technical fixes. It was against this backdrop that we arrived in Baku not only to witness the debate, but to contribute to shaping it.

Fernando Túlio Franco: Brownfields, Bus Corridors and the Climate–Housing Nexus

I arrived with a dual agenda: a WUF Academy keynote on The Climate-Housing Nexus Dialogue, exploring how decarbonisation and socio-territorial inequalities can be addressed together, and a C40/Arup/Urban Partners panel on brownfield regeneration, Europe’s most underused lever for tackling the housing and climate crises. My presentation drew on the Sarajevo Code design studio and a São Paulo case study, weaving together legal frameworks, social housing policies, participatory governance, and Land Value Capture mechanisms.

Mashael Yazdanie: Urban Energy, Sufficiency and Resilience

I brought an integrated urban energy, sufficiency, and resilience perspective to four WUF13 sessions, with a focus on housing, governance, and citizen participation: a UNDP-hosted dialogue on resilient housing systems; two sessions on citizen participation and disaster preparedness at the NGO Pavilion; and a session on translating global housing commitments into local action at the Azerbaijan Pavilion, co-convened with Tural Aliyev. My research asks a question rarely posed at large forums: how much is enough to live well within ecological limits? In Baku, I opened conversations about the governance and citizen engagement levers needed to make sufficiency a viable urban strategy.

Tural Aliyev: Governing the Housing Crisis Across Scales

I spoke across three panels on citizen participation, disaster preparedness, and cross-scale housing governance. Being in Baku carried a particular resonance: as a Swiss researcher with Azerbaijani origins at ETH Zurich, I embody the bridge between local knowledge and international academic excellence that WUF13 sought to build.

What Comes Next

A further highlight was the Swiss Ambassador reception, bringing together SECO representatives, senior UN officials, and researchers: a vivid example of science–policy–practice in action.

WUF13 is not an endpoint. The Baku Call to Action calls for housing to be reprioritised as a human right, for stronger state stewardship over land and finance, and for the next decade of World Urban Forums to be a decade of action. Bridging academy and city, connecting evidence to policy, designing at the intersection of climate, housing, and society; this is what we bring back from Baku. The work continues.

Smart Cities, Hot Climates: How Estefanía Tapias Turns Research into Real Urban Futures

Charles Bara — Thu, 08 Jan 2026 09:00:00 +0000

What will the cities of the future feel like? Will they be cooler, more resilient, more human, or simply bigger, faster, and hotter? According to ETH alumna Estefanía Tapias, no one has the answer. And that uncertainty is exactly what makes cities so fascinating.

In the latest episode of the We Are ETH podcast, host Susan Kish sits down with Estefanía, an architect, urban scientist, and Head of Smart & Digital for WSP in the Middle East, to explore her journey from Colombia to Zurich to Dubai and to understand how she is helping shape the cities of tomorrow in some of the world’s most extreme climates.

From Medellín to Zurich to Dubai: A Journey Shaped by Curiosity

Estefanía’s story began far from the desert skylines she works with today. Growing up in Colombia, she dreamed of becoming an artist. Architecture came next, followed by technology, data, and ultimately cities themselves.

“I’ve always been curious about cities,” she says. “How they evolve in 5, 10, 20 years… no one knows where we will be.”

That curiosity eventually brought her to ETH Zurich, where she completed her PhD under renowned professor Gerhard Schmitt at the Future Cities Laboratory. This pioneering hub blended urban science, technology, climate research, and design long before “smart cities” became a buzzword.

“For me, ETH was the perfect combination,” she recalls. “A visionary professor, a cutting-edge laboratory, and a city, Zurich, that I fell in love with at first sight.”

Those six months for her Master’s thesis turned into eight years. Zurich shaped not just her research but her life as well: “I ended up marrying a Swiss person. My daughter is Swiss. Everything came together very nicely.”

Why Dubai? A Laboratory for Big Ideas

Today, Estefanía works in Dubai, which she describes as similar to what Singapore felt like 15 years ago: a place buzzing with ambition, experimentation, and large-scale technological investment.

“There’s a momentum here,” she explains. “You see it in day-to-day life. They’re pushing innovation everywhere. Sometimes it works and sometimes it doesn’t, but that is simply part of building the future.”

She also points to Saudi Arabia, where entire cities are currently being built from scratch, something that no other region in the modern world is attempting at a comparable scale.

“In my lifetime, I will only have this opportunity once,” she says. “You learn from all the cities that came before, meaning what worked and what did not, and you apply it to a place being built from zero.”

Some projects succeed quietly. Others, such as The Line, have faced challenges. But even the difficult experiments matter.

“They pushed technology forward,” she says. “If it weren’t for these ambitious projects, the software and systems we use for city-building would not have advanced as quickly.”

When Heat Becomes the Challenge and the Teacher

Estefanía’s PhD focused on urban climate and sustainability long before she ever experienced what 45°C heat really feels like. “When I arrived in Dubai, the heat was unbearable. I thought: I cannot do this,” she laughs. “By my second summer, I realised I had adapted.”

Her research helped her recognise something essential:

Cities must adapt as well.

Extreme heat now shapes how cities must be designed, influencing shading, materials, energy systems, and public spaces. Traditional Gulf urbanism provides valuable clues, and technology offers new tools, yet people ultimately remain at the center.

“We need buildings that work with the environment instead of working against it through endless air conditioning,” she says. “There is so much opportunity to rethink how cities respond to heat.”

Why ETH? Vision, People, and a City That “Grew Organically”

When asked why she chose ETH Zurich for her PhD, Estefanía answers without hesitation: “It was the person I would work with, and it was also the city.”

Professor Schmitt’s vision shaped her academically. Zurich shaped her personally and professionally.

“It is modern but not too modern. It is technological but still full of culture. It is clean, safe, close to nature, and still very much a city,” she reflects. “It grew organically. It is still my favourite city in the world.”

Her perfect Zurich moment?

“A coffee by the lake, looking at the mountains full of snow.”

Advice to Young Urbanists: Move Where Cities are Moving

For students who dream of shaping cities, she offers the same advice she once received: “Go where things are happening. Don’t stay comfortable. Live in the places that are changing fast and learn from them.”

Her own path reflects that philosophy, moving from Turin to Zurich to Singapore and eventually to Dubai.

“It is easy to criticise from far away,” she says. “I wanted to come here, experience it, and solve problems instead of just pointing at them.”

Looking Ahead: The Future No One Can Predict

When asked what she is most curious about today, Estefanía lights up: “Future cities. How they evolve. How systems change. I wish I had a machine that took me 10 years forward and then brought me back.”

Until such a machine exists, she is helping build that future herself.
