Using AI to Map Urban Change

Curated on Posted on by Stefaan Verhulst

Brief by Tianyuan Huang, Zejia Wu, Jiajun Wu, Jackelyn Hwang, Ram Rajagopal: “Cities are constantly evolving, and better understanding those changes facilitates better urban planning and infrastructure assessments and leads to more sustainable social and environmental interventions. Researchers currently use data such as satellite imagery to study changing urban environments and what those changes mean for public policy and urban design. But flaws in the current approaches, such as inadequately granular data, limit their scalability and their potential to inform public policy across social, political, economic, and environmental issues.

Street-level images offer an alternative source of insights. These images are frequently updated and high-resolution. They also directly capture what’s happening on a street level in a neighborhood or across a city. Analyzing street-level images has already proven useful to researchers studying socioeconomic attributes and neighborhood gentrification, both of which are essential pieces of information in urban design, sustainability efforts, and public policy decision-making for cities. Yet, much like other data sources, street-level images present challenges: accessibility limits, shadow and lighting issues, and difficulties scaling up analysis.

To address these challenges, our paper “CityPulse: Fine-Grained Assessment of Urban Change with Street View Time Series” introduces a multicity dataset of labeled street-view images and proposes a novel artificial intelligence (AI) model to detect urban changes such as gentrification. We demonstrate the change-detection model’s effectiveness by testing it on images from Seattle, Washington, and show that it can provide important insights into urban changes over time and at scale. Our data-driven approach has the potential to allow researchers and public policy analysts to automate and scale up their analysis of neighborhood and citywide socioeconomic change…(More)”.

Governments Empower Citizens by Promoting Digital Rights

Curated on Posted on by Stefaan Verhulst

Article by Julia Edinger: “The rapid rise of digital services and smart city technology has elevated concerns about privacy in the digital age and government’s role, even as cities from California to Texas take steps to make constituents aware of their digital rights.

Earlier this month, Long Beach, Calif., launched an improved version of its Digital Rights Platform, which shows constituents their data privacy and digital rights and information about how the city uses technologies while protecting digital rights.

“People’s digital rights are no different from their human or civil rights, except that they’re applied to how they interact with digital technologies — when you’re online, you’re still entitled to every right you enjoy offline,” said Will Greenberg, staff technologist at the Electronic Frontier Foundation (EFF), in a written statement. The nonprofit organization defends civil liberties in the digital world.


Long Beach’s platform initially launched several years ago, to mitigate privacy concerns that came out of the 2020 launch of a smart city initiative, according to Long Beach CIO Lea Eriksen. When that initiative debuted, the Department of Innovation and Technology requested the City Council approve a set of data privacy guidelines to ensure digital rights would be protected, setting the stage for the initial platform launch. Its 2021 beta version has now been enhanced to offer information on 22 city technology uses, up from two, and an enhanced feedback module enabling continued engagement and platform improvements…(More)”.

Artificial intelligence and the local government: A five-decade scientometric analysis on the evolution, state-of-the-art, and emerging trends

Curated on Posted on by Stefaan Verhulst

Paper by Tan Yigitcanlar et al: “In recent years, the rapid advancement of artificial intelligence (AI) technologies has significantly impacted various sectors, including public governance at the local level. However, there exists a limited understanding of the overarching narrative surrounding the adoption of AI in local governments and its future. Therefore, this study aims to provide a comprehensive overview of the evolution, current state-of-the-art, and emerging trends in the adoption of AI in local government. A comprehensive scientometric analysis was conducted on a dataset comprising 7112 relevant literature records retrieved from the Scopus database in October 2023, spanning over the last five decades. The study findings revealed the following key insights: (a) exponential technological advancements over the last decades ushered in an era of AI adoption by local governments; (b) the primary purposes of AI adoption in local governments include decision support, automation, prediction, and service delivery; (c) the main areas of AI adoption in local governments encompass planning, analytics, security, surveillance, energy, and modelling; and (d) under-researched but critical research areas include ethics of and public participation in AI adoption in local governments. This study informs research, policy, and practice by offering a comprehensive understanding of the literature on AI applications in local governments, providing valuable insights for stakeholders and decision-makers…(More)”.

Building SimCity: How to Put the World in a Machine

Curated on Posted on by Stefaan Verhulst

Book by Chaim Gingold: “…explores the history of computer simulation by chronicling one of the most influential simulation games ever made: SimCity. As author Chaim Gingold explains, Will Wright, the visionary designer behind the urban planning game, created SimCity in part to learn about cities, thinking about the world as a complex system and appropriating ideas from traditions in which computers are used for modeling. As such, SimCity is a microcosm of the histories and cultures of computer simulation that engages with questions, themes, and representational techniques that reach back to the earliest computer simulations.

Gingold uses SimCity to explore a web of interrelated topics in the history of technology, software, and simulation, taking us far and wide—from the dawn of programmable computers to miniature cities made of construction paper and role-play. An unprecedented history of Maxis, the company founded to bring SimCity to market, the book reveals Maxis’s complex relations with venture capitalists, Nintendo, and the Santa Fe Institute, which shaped the evolution of Will Wright’s career; Maxis’s failure to back The Sims to completion; and the company’s sale to Electronic Arts.

A lavishly visual book, Building SimCity boasts a treasure trove of visual matter to help bring its wide-ranging subjects to life, including painstakingly crafted diagrams that explain SimCity‘s operation, the Kodachrome photographs taken by Charles Eames of schoolchildren making model cities, and Nintendo’s manga-style “Dr. Wright” character design, just to name a few…(More)”.

Groups want N.Y. to disaggregate data of Middle Eastern, North African individuals

Curated on Posted on by Stefaan Verhulst

Article by Luke Parsnow: “A group of organizations are pushing for New York lawmakers to pass a bill that would disaggregate data of Middle Eastern and North African (MENA) individuals, according to a letter sent Monday.

The bill (S6584-B/A6219-A) would direct every state agency, board, department and commission that collects demographic data to use separate categories to collect data for the “White” and “Middle Eastern or North African” groups.

“Our organizations have seen firsthand the impact of the systemic exclusion of Middle Eastern and North African communities from data collection,” the letter reads. “Our communities do not perceive themselves to be white and are not perceived to be white. We also experience various disparities compared to non-Hispanic whites that go unseen because of the lack of data.”

The group says those communities categorized as “White” hinders those communities in education, employment, housing, health care and political representation.

“Miscategorizing a New Yorker’s race is not only offensive, but has real-world impacts on services and resources my particular communities receive,” Senate Deputy Leader Michael Gianaris said in a statement. “It should be obvious that people from the Middle East or North Africa are not white, yet that is how our laws define them.”

Gianaris said the legislation would give many New Yorkers better representation and a more powerful voice.

“The lack of a MENA category has hindered our understanding of the needs of MENA communities and our ability to consider those needs in decision-making and resource allocation,” according to the letter…(More)”.

‘Positive deviance’ and the power of outliers

Curated on Posted on by Stefaan Verhulst

Bloomberg Cities Network: “Groundbreaking solutions in cities are often the result of visionary mayoral leadership. But sometimes certain communities achieve significantly better outcomes than their similarly resourced neighbors—and the underlying reasons may not be immediately obvious to local leaders. Ravi Gurumurthy, CEO of the global innovation foundation Nesta, believes that this variation in quality of life at a hyper-local level is something worth paying a lot more attention to. 

“The fastest way for us to improve people’s lives will be to mine that variation and really understand what is going on,” he says.    

This concept, known as “positive deviance,” describes individuals or communities that achieve remarkable success or exhibit highly effective behaviors despite facing the same constraints as their peers. With a long history of use in international development, positive deviance is now gaining traction among city leaders as a source of solutions to stubborn urban challenges.  

Here’s a closer look at what it’s about, and how it’s already being used to uplift promising approaches in cities. 

What is positive deviance? 

Positive deviance first gained widespread attention because of a remarkable success story in 1990s Vietnam. Much of the country was suffering from a malnutrition crisis, and efforts to design and implement new solutions were coming up short. But aid workers landed on a breakthrough by paying closer attention to children who already appeared larger and healthier than their peers.  

It turned out these children were being fed different diets—leaning more heavily on shrimp and crab, for example, which were widely accessible but less often fed to young people. These children also were being fed more frequently, in smaller meals, throughout the day—an intervention that, again, did not require parents to have more resources so much as to differently use what was universally available.  

When these practices—feeding kids shellfish and making meals smaller and more frequent—were replicated, malnutrition plummeted…(More)”

A Literature Review on the Paradoxes of Public Interest in Spatial Planning within Urban Settings with Diverse Stakeholders

Curated on Posted on by Stefaan Verhulst

Paper by Danai Machakaire and Masilonyane Mokhele: “The concept of public interest legitimises the planning profession, provides a foundational principle, and serves as an ethical norm for planners. However, critical discourses highlight the problems of the assumptions underlying the notion of public interest in spatial planning. Using an explorative literature review approach, the article aims to analyse various interpretations and applications of public interest in spatial planning. The literature search process, conducted between August and November 2023, targeted journal articles and books published in English and focused on the online databases of Academic Search Premier, Scopus, and Google Scholar. The final selected literature comprised 71 sources. The literature showed that diverse conceptualisations of public interest complicate the ways spatial planners and authorities incorporate it in planning tools, processes, and products. This article concludes by arguing that the prospects of achieving a single definition of the public interest concept are slim and may not be necessary given the heterogeneous conceptualisation and the multiple operational contexts of public interest. The article recommends the development of context-based analytical frameworks to establish linkages that would lead towards the equitable inclusion of public interest in spatial planning…(More)”.

Cities Are at the Forefront of AI and Civic Engagement

Curated on Posted on by Stefaan Verhulst

Article by Hollie Russon Gilman and Sarah Jacob: “…cities worldwide are already adopting AI for everyday governance needs. Buenos Aires is integrating communication with residents through Boti, an AI chatbot accessible via WhatsApp. Over 5 million residents are using the chatbot everyday month, with some months upwards of 11 million users. Boti connects residents with city services such as bike sharing or social care programs or reports. Unlike other AI systems with a closed loop, Boti can connect externally to help residents with other government services. For more sensitive issues, such as domestic abuse, Boti can connect residents with a human operator. AI, in this context, offers residents a convenient means to efficiently engage with city resources and communicate with city employees.

Another example of AI improving people’s everyday lives is SomosUna, a partnership between the Inter American Development Bank and Next2MyLife, aims to address gender-based violence in Uruguay. In response to the rise in gender-based violence during and after Covid, this initiative aims to prevent violence through a network of support and “helpers” which includes 1) training 2) technology and 3) a community of volunteers. This initiative will leverage AI technology to enhance its support network, advancing preventative measures and providing immediate assistance.

While AI can foster engagement, local government officials recognize that they must pre-engage the public to determine the role that AI should play in civic life across diverse cities. This pre-engagement and education will inform the ethical standards and considerations against which AI will be assessed.

The EU’s ITHACA project, for example, explores the application of AI in civic participation and local governance…(More)”… See also: AI Localism.

Being Human in Digital Cities

Curated on Posted on by Stefaan Verhulst

Book by Myria Georgiou: “…sets out to investigate the new configuration of social order that is taking shape in today’s cities. Although routed through extractive datafication, compulsive connectivity, and regulatory AI technologies, this digital order nonetheless displaces technocentrism and instead promotes new visions of humanism, all in the name of freedom, diversity, and sustainability. But the digital order emerges in the midst of neoliberal instability and crises, resulting in a plurality of contrasting responses to securing digitally mediated human progress. While corporate, media, and state actors mobilize such positive sociotechnical imaginaries to promise digitally mediated human progress, urban citizens and social movements propose alternative pathways to autonomy and dignity through and sometimes against digital technologies.

Investigating the dynamic workings of technology and power from a transnational and comparative perspective, this book reveals the contradictory claims and struggles for the future of digital cities and their humanity. In doing so, it will enrich understandings of digital urbanism, critical data studies, and critical humanist studies.​..(More)”.
