In Droit de cité, Professor Carlos Moreno presents a compelling vision of urban life that challenges the current model of sprawling, car-dependent cities. The book, published in 2020, delves into the urgent need for cities to reinvent themselves in an era of rapid urbanization, environmental crisis, and technological shifts. At the core of Moreno’s argument is the concept of the «15-Minute City,» a revolutionary model that promotes human-centric urban design, decentralization, and local living. With contributions from esteemed thinkers like Richard Sennett, Saskia Sassen, and Edgar Morin, the book offers a multidimensional exploration of how we can transform our urban environments for a more sustainable and inclusive future.
The Core Concept: The 15-Minute City
The idea behind the «15-Minute City» is simple yet profound: people should be able to access all their essential needs, such as work, shopping, healthcare, education, and leisure, within a 15-minute radius of their homes, either on foot or by bicycle. Moreno argues that our current urban models prioritize efficiency over well-being, forcing people into long commutes and disconnected lifestyles. He envisions a future where cities are polycentric, meaning that every neighborhood functions as a self-sufficient hub, reducing unnecessary travel and fostering vibrant local communities.
Moreno presents a strong case for why this model is necessary. He highlights how urban sprawl, car dependency, and socio-economic segregation have led to increased pollution, diminished quality of life, and rising inequalities. The «15-Minute City» aims to reverse these trends by prioritizing mixed-use development, pedestrian-friendly infrastructure, and decentralized governance.
A Systemic Analysis of Urbanization
In this book, Moreno examines the acceleration of urban growth and the negative consequences of the metropolitan expansion model through a thorough analysis of urbanization in the 21st century. He argues that modern cities model has always been designed around the idea of economic efficiency rather than social well-being. This resulted in fragmented communities and environmental degradation.
He also explores how the COVID-19 pandemic has acted as a catalyst for rethinking urban life, forcing cities worldwide to reconsider their infrastructure and the importance of local accessibility. Moreno suggests that the pandemic demonstrated the feasibility of remote work and local living, reinforcing the need for a paradigm shift toward decentralized urban planning.
The Role of Technology in Urban Transformation
Technology plays a crucial role in Moreno’s vision. He sees digital tools as key enablers of the 15-Minute City, allowing residents to better connect with local resources and services. According to Moreno, smart urban planning in combination with data-driven decision-making, and innovations like shared mobility and telemedicine can all support the creation of more liveable and efficient cities.
However, Moreno also warns against the dangers of unchecked technological expansion. He critiques «smart city» initiatives that prioritize surveillance and corporate interests over genuine community well-being. He argues that technology should be used to enhance human connections rather than replace them. His vision is one of a «smart human city» rather than just a technologically advanced one.
Contributions from Leading Thinkers
The book’s credibility is reinforced by contributions from renowned urban thinkers. Richard Sennett, in his preface, contextualizes Moreno’s ideas within the broader history of urbanism. Saskia Sassen’s afterword offers a global perspective on urban transformation, while Edgar Morin provides philosophical insights into the human-centered nature of city life.
These contributions not only enrich the book, grounding Moreno’s ideas in both historical and contemporary discussions about urban living, but also highlight the necessity of an interdisciplinary approach to urban planning, one that blends sociology, economics, environmental science, and philosophy.
Challenges and Criticisms
While Droit de cité presents an inspiring vision, its potential criticism is the difficulty of implementing the 15-Minute City in already existing urban landscapes, particularly in highly car-dependent areas. Moreno acknowledges this but argues that cities must adopt gradual transformations through policy changes, incentives for mixed-use development, and investments in public infrastructure.
Another challenge is the potential for gentrification. As neighbourhoods become more desirable due to better infrastructure and amenities, property values may rise, pushing out lower-income residents. Moreno touches on this issue, advocating for inclusive housing policies and rent control measures to ensure that local communities remain diverse and accessible.
Conclusion
Droit de cité is an inspiring book and a must-read for urban planners, policymakers, and anyone interested in the future of cities. Moreno’s vision of the 15-Minute City is not just a theoretical model, it is a call to action for urban transformation that prioritizes people over cars, local communities over corporate interests, and sustainability over unchecked growth.
As cities worldwide are faced with issues of congestion, inequality, and climate change, Moreno’s insights provide a roadmap for a more humane and resilient urban future. His book is a powerful reminder that cities should serve their inhabitants, not the other way around.
