The Century of Cities

Jonathan Reckford, CEO of Habitat for Humanity International, joins The Century of Cities as part of our special miniseries in collaboration with UN-Habitat. Building on conversations emerging from World Urban Forum 13 in Baku, Jonathan reflects on a world where rapid urbanization, climate pressures, migration, and rising construction costs have combined to create a housing crisis affecting cities across every region of the world. At the heart of the conversation is a challenge to conventional thinking: solving the housing crisis is not simply about building more homes. It is about expanding access to the systems, opportunities, and pathways that make housing possible. From informal settlements and incremental housing to land rights, finance, and market access, Jonathan explores why housing solutions must be designed around the realities of how people live, build, and improve their communities. Housing, he argues, is not simply shelter. It is a foundation for opportunity, resilience, and human flourishing. As the global community prepares for the upcoming SDG 11 Review and the United Nations General Assembly High-Level Meeting on the New Urban Agenda, conversations that began at World Urban Forum 13 will continue there. This episode is part of that broader dialogue on the future of cities.

The Century of Cities welcomes Sowmya Parthasarathy, an Architect and Urban Designer leading Arup's Masterplanning and Urban Design team in London, who examines how city planning has shifted from centralized, top-down systems toward more people-centred and regenerative approaches. Drawing on her experience in 1980s New Delhi and her work across the UK, US, Middle East, and India, she reflects on how rapid urbanization outpaced planning capacity, and how climate risk and housing affordability now define urban priorities. Looking to 2080, she argues that cities must move beyond net zero toward regenerative models that align human and natural systems. Drawing on her work with the UK's New Towns Task Force, she explores densification, retrofit, and the role of new towns, emphasizing that long-term success depends on integrating housing, infrastructure, placemaking, and stewardship into a single, sustained civic vision.

In this episode of The Century of Cities, Rohit T. Aggarwala, Commissioner of NYC Environmental Protection and former Chief Climate Officer, reflects on a century of urban change through the lens of New York's environmental, infrastructural, and governance evolution. He traces the city's trajectory from the fiscal and environmental crises of the late twentieth century to its present condition, marked by cleaner air and water, renewed waterfronts, and the pressures that accompany urban demand. He argues that climate change will eclipse affordability and growth as the defining urban challenge. He outlines a pragmatic understanding of resilience, one that prioritizes protection of life, housing, and core systems over the pursuit of uninterrupted normalcy. From stormwater and coastal defences to mobility and water management, the discussion emphasizes the need for long-term investment, institutional flexibility, and political leadership capable of navigating disruption. The future of cities, he suggests, will depend on the capacity to make difficult choices early, at scale, and with a clear understanding of risk.

The Century of Cities welcomes Tim Williams, Cities Lead at Grimshaw and a leading voice in global urban strategy, to explore how cities move through cycles of growth, decline, and reinvention. Drawing on his upbringing in the South Wales Valleys and years advising governments in the UK and Australia, Tim reflects on the shift from industrial cities built on extraction to contemporary urban economies shaped by knowledge, lifestyle, and connectivity. He emphasizes that urban change is rarely linear and that periods of transition often involve loss, uncertainty, and uneven outcomes. Tim offers a sharp critique of the global housing crisis, arguing that it cannot be solved by supply alone. He explains how the over-financialization of housing and a disconnect between public expectations and private-sector business models have created a systemic impasse. Rather than blaming developers, Tim calls for a broader mix of housing delivery models, including a renewed role for non-market housing and stronger public-sector capacity. Looking ahead, he warns that many cities may soon face a new reality, managing stagnation or decline and urges more honest international dialogue about how cities adapt when growth is no longer guaranteed.

The Century of Cities welcomes Andrew Carter, Chief Executive of Centre for Cities, who reflects on how UK cities have evolved, and why uneven progress still defines the urban landscape. He traces the shift from industrial decline and urban decay to a renewed belief in cities as drivers of economic growth, powered by the knowledge economy and higher education. Andrew emphasizes that this revival was not inevitable, but the result of long-term structural change and deliberate policy choices. He argues that deeper devolution, especially greater control over transport, planning, and funding, is essential if cities are to unlock productivity and inclusion. While elected mayors and combined authorities have moved the agenda forward, he warns that without real fiscal autonomy, many UK cities will continue to lag behind their European peers. His message is clear: empowered cities, strong public transport, and well-managed density are central to national renewal.

Season 2 of The Century of Cities continues with part two of our in-depth conversation with Michael Storper, one of the world's leading economic geographers. In this episode, Michael turns his focus to governance, institutions, and the hard trade-offs shaping urban futures in the United States and Europe. Drawing on comparative insights from California, the Bay Area, Los Angeles, and major European regions, he examines how prosperity, inequality, and cultural path dependency collide in today's superstar cities. Michael offers a rigorous critique of dominant housing narratives, arguing that supply-led solutions alone cannot resolve affordability in highly unequal urban economies. He contrasts American and European approaches, highlighting the role of social housing, construction innovation, and public-sector leadership in maintaining social mix and urban quality. The conversation expands to Europe's innovation dilemma, questioning whether the continent's urban system is structurally equipped to compete in a global knowledge economy while sustaining cohesion across regions. Throughout, Michael calls for greater honesty in urban policy debates, emphasizing that cities face real trade-offs that cannot be wished away. The future of cities depends not just on growth, but on institutions capable of managing complexity, inequality, and long-term transformation.

The Century of Cities celebrates our 100th guest as we welcome Lord Norman Foster, one of the world's most influential architects and Founder and Executive Chairman of Foster + Partners. Drawing on six decades of practice, he traces the shift from gritty, industrial cities to cleaner, safer, and more mobile urban environments, shaped by digital technology, new forms of mobility, and changing patterns of density. While progress has been undeniable, Lord Foster warns that many cities have lost distinct identity, creativity, and affordability along the way. He makes a powerful case for rediscovering the lessons of the traditional city: compactness, mixed use, walkability, and strong public spaces. From Madrid and Vienna to London, Paris, and New York, he argues that density done well is not only more sustainable but also more joyful and socially resilient. He calls for a return to positive, big-picture planning, investing in infrastructure, embracing layered cities, and designing streets and neighbourhoods that support daily life and long-term health. His vision for the future is optimistic but clear-eyed: greener, quieter, more humane cities are possible, but only if technological innovation is matched with human-centred design and the courage to plan for generations to come.

The Century of Cities welcomes Andrés Rodríguez-Pose, Professor of Economic Geography and Regional Planning, to examine deep spatial inequalities shaping politics, prosperity, and trust in institutions across the world. Drawing on decades of research, Andrés explains how economic growth has become increasingly concentrated in a small number of cities and regions, while many places have been systematically left behind, creating what he describes as the "geography of discontent." He explores how neglecting these regions has fueled political polarization, social fragmentation, and rising distrust in democratic systems. Andrés challenges the assumption that growth alone will solve spatial inequality. He argues for place-sensitive policies that recognize the unique assets, constraints, and identities of different regions rather than one-size-fits-all solutions. From rethinking innovation policy to rebuilding local capacity and dignity, Andrés makes a compelling case that the future of cities, regions, and democracy itself depends on addressing territorial inequality head-on, and doing so with long-term commitment rather than short-term fixes.
