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.
