How cities are reinventing the public-private partnership − 4 lessons from around the globe


Article by Debra Lam: “Cities tackle a vast array of responsibilities – from building transit networks to running schools – and sometimes they can use a little help. That’s why local governments have long teamed up with businesses in so-called public-private partnerships. Historically, these arrangements have helped cities fund big infrastructure projects such as bridges and hospitals.

However, our analysis and research show an emerging trend with local governments engaged in private-sector collaborations – what we have come to describe as “community-centered, public-private partnerships,” or CP3s. Unlike traditional public-private partnerships, CP3s aren’t just about financial investments; they leverage relationships and trust. And they’re about more than just building infrastructure; they’re about building resilient and inclusive communities.

As the founding executive director of the Partnership for Inclusive Innovation, based out of the Georgia Institute of Technology, I’m fascinated with CP3s. And while not all CP3s are successful, when done right they offer local governments a powerful tool to navigate the complexities of modern urban life.

Together with international climate finance expert Andrea Fernández of the urban climate leadership group C40, we analyzed community-centered, public-private partnerships across the world and put together eight case studies. Together, they offer valuable insights into how cities can harness the power of CP3s.

4 keys to success

Although we looked at partnerships forged in different countries and contexts, we saw several elements emerge as critical to success over and over again.

• 1. Clear mission and vision: It’s essential to have a mission that resonates with everyone involved. Ruta N in Medellín, Colombia, for example, transformed the city into a hub of innovation, attracting 471 technology companies and creating 22,500 jobs.

This vision wasn’t static. It evolved in response to changing local dynamics, including leadership priorities and broader global trends. However, the core mission of entrepreneurship, investment and innovation remained clear and was embraced by all key stakeholders, driving the partnership forward.

 2. Diverse and engaged partners: Successful CP3s rely on the active involvement of a wide range of partners, each bringing their unique expertise and resources to the table. In the U.K., for example, the Hull net-zero climate initiative featured a partnership that included more than 150 companies, many small and medium-size. This diversity of partners was crucial to the initiative’s success because they could leverage resources and share risks, enabling it to address complex challenges from multiple angles.

Similarly, Malaysia’s Think City engaged community-based organizations and vulnerable populations in its Penang climate adaptation program. This ensured that the partnership was inclusive and responsive to the needs of all citizens…(More)”.

Towards Civic Digital Twins: Co-Design the Citizen-Centric Future of Bologna


Paper by Massimiliano Luca et al: “We introduce Civic Digital Twin (CDT), an evolution of Urban Digital Twins designed to support a citizen-centric transformative approach to urban planning and governance. CDT is being developed in the scope of the Bologna Digital Twin initiative, launched one year ago by the city of Bologna, to fulfill the city’s political and strategic goal of adopting innovative digital tools to support decision-making and civic engagement. The CDT, in addition to its capability of sensing the city through spatial, temporal, and social data, must be able to model and simulate social dynamics in a city: the behavior, attitude, and preference of citizens and collectives and how they impact city life and transform transformation processes. Another distinctive feature of CDT is that it must be able to engage citizens (individuals, collectives, and organized civil society) and other civic stakeholders (utilities, economic actors, third sector) interested in co-designing the future of the city. In this paper, we discuss the motivations that led to the definition of the CDT, define its modeling aspects and key research challenges, and illustrate its intended use with two use cases in urban mobility and urban development…(More)”.

Digital surveillance capitalism and cities: data, democracy and activism


Paper by Ashish Makanadar: “The rapid convergence of urbanization and digital technologies is fundamentally reshaping city governance through data-driven systems. This transformation, however, is largely controlled by surveillance capitalist entities, raising profound concerns for democratic values and citizen rights. As private interests extract behavioral data from public spaces without adequate oversight, the principles of transparency and civic participation are increasingly threatened. This erosion of data sovereignty represents a critical juncture in urban development, demanding urgent interdisciplinary attention. This comment proposes a paradigm shift in urban data governance, advocating for the reclamation of data sovereignty to prioritize community interests over corporate profit motives. The paper explores socio-technical pathways to achieve this goal, focusing on grassroots approaches that assert ‘data dignity’ through privacy-enhancing technologies and digital anonymity tools. It argues for the creation of distributed digital commons as viable alternatives to proprietary data silos, thereby democratizing access to and control over urban data. The discussion extends to long-term strategies, examining the potential of blockchain technologies and decentralized autonomous organizations in enabling self-sovereign data economies. These emerging models offer a vision of ‘crypto-cities’ liberated from extractive data practices, fostering environments where residents retain autonomy over their digital footprints. By critically evaluating these approaches, the paper aims to catalyze a reimagining of smart city technologies aligned with principles of equity, shared prosperity, and citizen empowerment. This realignment is essential for preserving democratic values in an increasingly digitized urban landscape…(More)”.

Shifting Patterns of Social Interaction: Exploring the Social Life of Urban Spaces Through A.I.


Paper by Arianna Salazar-Miranda, et al: “We analyze changes in pedestrian behavior over a 30-year period in four urban public spaces located in New York, Boston, and Philadelphia. Building on William Whyte’s observational work from 1980, where he manually recorded pedestrian behaviors, we employ computer vision and deep learning techniques to examine video footage from 1979-80 and 2008-10. Our analysis measures changes in walking speed, lingering behavior, group sizes, and group formation. We find that the average walking speed has increased by 15%, while the time spent lingering in these spaces has halved across all locations. Although the percentage of pedestrians walking alone remained relatively stable (from 67% to 68%), the frequency of group encounters declined, indicating fewer interactions in public spaces. This shift suggests that urban residents increasingly view streets as thoroughfares rather than as social spaces, which has important implications for the role of public spaces in fostering social engagement…(More)”.

Quantitative Urban Economics


Paper by Stephen J. Redding: “This paper reviews recent quantitative urban models. These models are sufficiently rich to capture observed features of the data, such as many asymmetric locations and a rich geography of the transport network. Yet these models remain sufficiently tractable as to permit an analytical characterization of their theoretical properties. With only a small number of structural parameters (elasticities) to be estimated, they lend themselves to transparent identification. As they rationalize the observed spatial distribution of economic activity within cities, they can be used to undertake counterfactuals for the impact of empirically-realistic public-policy interventions on this observed distribution. Empirical applications include estimating the strength of agglomeration economies and evaluating the impact of transport infrastructure improvements (e.g., railroads, roads, Rapid Bus Transit Systems), zoning and land use regulations, place-based policies, and new technologies such as remote working…(More)”.

Addressing Data Challenges to Drive the Transformation of Smart Cities


Paper by Ekaterina Gilman et al: “Cities serve as vital hubs of economic activity and knowledge generation and dissemination. As such, cities bear a significant responsibility to uphold environmental protection measures while promoting the welfare and living comfort of their residents. There are diverse views on the development of smart cities, from integrating Information and Communication Technologies into urban environments for better operational decisions to supporting sustainability, wealth, and comfort of people. However, for all these cases, data are the key ingredient and enabler for the vision and realization of smart cities. This article explores the challenges associated with smart city data. We start with gaining an understanding of the concept of a smart city, how to measure that the city is a smart one, and what architectures and platforms exist to develop one. Afterwards, we research the challenges associated with the data of the cities, including availability, heterogeneity, management, analysis, privacy, and security. Finally, we discuss ethical issues. This article aims to serve as a “one-stop shop” covering data-related issues of smart cities with references for diving deeper into particular topics of interest…(More)”.

Understanding local government responsible AI strategy: An international municipal policy document analysis


Paper by Anne David et al: “The burgeoning capabilities of artificial intelligence (AI) have prompted numerous local governments worldwide to consider its integration into their operations. Nevertheless, instances of notable AI failures have heightened ethical concerns, emphasising the imperative for local governments to approach the adoption of AI technologies in a responsible manner. While local government AI guidelines endeavour to incorporate characteristics of responsible innovation and technology (RIT), it remains essential to assess the extent to which these characteristics have been integrated into policy guidelines to facilitate more effective AI governance in the future. This study closely examines local government policy documents (n = 26) through the lens of RIT, employing directed content analysis with thematic data analysis software. The results reveal that: (a) Not all RIT characteristics have been given equal consideration in these policy documents; (b) Participatory and deliberate considerations were the most frequently mentioned responsible AI characteristics in policy documents; (c) Adaptable, explainable, sustainable, and accountable considerations were the least present responsible AI characteristics in policy documents; (d) Many of the considerations overlapped with each other as local governments were at the early stages of identifying them. Furthermore, the paper summarised strategies aimed at assisting local authorities in identifying their strengths and weaknesses in responsible AI characteristics, thereby facilitating their transformation into governing entities with responsible AI practices. The study informs local government policymakers, practitioners, and researchers on the critical aspects of responsible AI policymaking…(More)” See also: AI Localism

City Tech


Book by Rob Walker: “The world is rapidly urbanizing, and experts predict that up to 80 percent of the population will live in cities by 2050.

Federal Court Invalidates NYC Law Requiring Food Delivery Apps to Share Customer Data with Restaurants


Article by Hunton, Andrews, Kurth: “On September 24, 2024, a federal district court held that New York City’s “Customer Data Law” violates the First Amendment. Passed in the summer of 2021, the law requires food-delivery apps to share customer-specific data with restaurants that prepare delivered meals.

The New York City Council enacted the Customer Data Law to boost the local restaurant industry in the wake of the pandemic. The law requires food-delivery apps to provide restaurants (upon the restaurants’ request) with each diner’s full name, email address, phone number, delivery address, and order contents. Customers may opt out of such sharing. The law’s supporters argue that requiring such disclosure addresses exploitation by the delivery apps and helps restaurants advertise more effectively.

Normally, when a customer places an order through a food-delivery app, the app provides the restaurant with the customer’s first name, last initial and food order. Food-delivery apps share aggregate data analytics with restaurants but generally do not share customer-specific data beyond the information necessary to fulfill an order. Some apps, for example, provide restaurants with data related to their menu performance, customer feedback and daily operations.

Major food-delivery app companies challenged the Customer Data Law, arguing that its data sharing requirement compels speech impermissibly under the First Amendment. Siding with the apps, the U.S. District Court for the Southern District of New York declared the city’s law invalid, holding that its data sharing requirement is not appropriately tailored to a substantial government interest…(More)”.
