City divide. Fighting urban inequalities

Context and Origin of the Resource

The publication City divide. Fighting urban inequalities is issued by Fondazione Giangiacomo Feltrinelli, a prominent Italian cultural foundation that supports research and public debate on social issues. The work is edited by Tommaso Vitale and includes contributions from scholars such as Marietta Haffner, Matteo Innocenti, Paul Lichterman, Ronke Oluwadare, Sara Sampietro, Dimitra Siatitsa and Michael Storper. The authors represent a mix of urban geographers, sociologists, economists and climate‑change specialists from institutions across Europe and the United States, providing a multidisciplinary perspective on urban disparity.

Scope and Main Themes

The book examines five principal dimensions of urban inequality: (1) inter‑regional development gaps, (2) intra‑city income and status differentials, (3) neighbourhood‑level income disparities, (4) spatial experience and access to public goods, and (5) inter‑generational mobility linked to place. It argues that inequalities are not inevitable; policy choices, governance capacity and inclusive planning can reshape urban trajectories. Climate change, housing affordability, and the cost‑of‑living crisis are presented as intersecting drivers that amplify existing gaps.

Key Quantitative Findings

• Between 1996 and 2022, house prices in OECD cities rose by 77 percent, while GDP per‑capita grew only 29 percent, widening the affordability gap.
• In 2022, 20 percent of EU households spent more than 40 percent of disposable income on housing costs, with the share rising to 34 percent among the at‑risk‑of‑poverty population.
• Climate‑related extreme events, such as the 2022 European drought, highlighted the vulnerability of urban water supplies and contributed to a broader food‑security crisis.
• Air‑pollution levels remain high in dense, low‑income cities; fine particulate matter (PM2.5) is linked to 21 percent of global neuro‑degenerative disease burden.
• In the UK, northern cities experience cost‑of‑living inflation up to 30 percent higher than southern regions, driven by poorer home insulation and higher car dependency.

Housing Crisis and Policy Responses

The authors note that public‑social housing accounts for only 0‑5 percent of total housing stock in most Southern European countries, with Italy’s social sector comprising roughly 5 percent. Institutional investors hold substantial shares of residential assets—e.g., €40 billion in Berlin—pressuring rents upward. Successful models, such as Vienna’s de‑commodified housing (≈ 43 percent of dwellings), demonstrate that mixed‑income, rent‑controlled schemes can keep household housing expenditures below 10 percent of pre‑tax income. The book also highlights the role of community land trusts and cooperative housing in stabilising rents and fostering social mix.

Climate Adaptation and Urban Health

Urban heat islands raise city temperatures by 4‑5 °C compared with rural surroundings, aggravating heat‑related morbidity and mortality. Green infrastructure, nature‑based solutions and “healthy corridors” are proposed to mitigate temperature spikes and improve air quality. The authors cite the Paris energy‑sobriety plan, which achieved a 10 percent reduction in municipal energy use through measures such as lowering public‑building temperatures and dimming street lighting.

Governance, Inclusion and Civic Action

Effective governance is framed as a blend of flexible, evidence‑based policy and participatory mechanisms. Case studies from Milan, Paris and Los Angeles illustrate how citizen coalitions, community‑of‑interest alliances and identity‑based movements can influence housing regulation, rent‑control ordinances and inclusive urban design. The authors stress that durable coalitions, interdisciplinary collaboration and transparent decision‑making are essential for scaling equitable interventions across Europe.

Future Outlook for Sustainable Housing

The publication concludes that sustainable, affordable housing is achievable through coordinated policy instruments: (i) expanding de‑commodified housing stock, (ii) integrating green and blue infrastructure to address climate stressors, (iii) enforcing rent‑control and inclusionary zoning, and (iv) fostering citizen participation in planning processes. By aligning economic incentives with social equity, European cities can mitigate spatial disparities while advancing climate resilience and public health goals.
