The term “smart cities” originated as a marketing strategy for large IT vendors. It has now become synonymous with urban uses of technology, particularly advanced and emerging technologies. But cities are more than 5G, big data, driverless vehicles, and AI. They are crucial drivers of opportunity, prosperity, and progress. They support those displaced by war and crisis and generate 80% of global GDP. More than 68% of the world’s population will live in cities by 2050—2.5 billion more people than do now. And with over 90% of urban areas located on coasts, cities are on the front lines of climate change.
A focus on building “smart cities” risks turning cities into technology projects. We talk about “users” rather than people. Monthly and “daily active” numbers instead of residents. Stakeholders and subscribers instead of citizens. This also risks a transactional—and limiting—approach to city improvement, focusing on immediate returns on investment or achievements that can be distilled into KPIs.
Truly smart cities recognize the ambiguity of lives and livelihoods, and they are driven by outcomes beyond the implementation of “solutions.” They are defined by their residents’ talents, relationships, and sense of ownership—not by the technology that is deployed there.
This more expansive concept of what a smart city is encompasses a wide range of urban innovations. Singapore, which is exploring high-tech approaches such as drone deliveries and virtual-reality modeling, is one type of smart city. Curitiba, Brazil—a pioneer of the bus rapid transit system—is another. Harare, the capital of Zimbabwe, with its passively cooled shopping center designed in 1996, is a smart city, as are the “sponge cities” across China that use nature-based solutions to manage rainfall and floodwater.
Where technology can play a role, it must be applied thoughtfully and holistically—taking into account the needs, realities, and aspirations of city residents. Guatemala City, in collaboration with our country office team at the UN Development Programme, is using this approach to improve how city infrastructure—including parks and lighting—is managed. The city is standardizing materials and designs to reduce costs and labor, and streamlining approval and allocation processes to increase the speed and quality of repairs and maintenance. Everything is driven by the needs of its citizens. Elsewhere in Latin America, cities are going beyond quantitative variables to take into account well-being and other nuanced outcomes.
In her 1961 book The Death and Life of Great American Cities, Jane Jacobs, the pioneering American urbanist, discussed the importance of sidewalks. In the context of the city, they are conduits for adventure, social interaction, and unexpected encounters—what Jacobs termed the “sidewalk ballet.” Just as literal sidewalks are crucial to the urban experience, so is the larger idea of connection between elements.
Truly smart cities recognize the ambiguity of lives and livelihoods, and they are driven by outcomes beyond the implementation of “solutions.”
However, too often we see “smart cities” focus on discrete deployments of technology rather than this connective tissue. We end up with cities defined by “use cases” or “platforms.” Practically speaking, the vision of a tech-centric city is conceptually, financially, and logistically out of reach for many places. This can lead officials and innovators to dismiss the city’s real and substantial potential to reduce poverty while enhancing inclusion and sustainability.
In our work at the UN Development Programme, we focus on the interplay between different components of a truly smart city—the community, the local government, and the private sector. We also explore the different assets made available by this broader definition: high-tech innovations, yes, but also low-cost, low-tech innovations and nature-based solutions. Big data, but also the qualitative, richer detail behind the data points. The connections and “sidewalks”—not just the use cases or pilot programs. We see our work as an attempt to start redefining smart cities and increasing the size, scope, and usefulness of our urban development tool kit.
We continue to explore how digital technology might enhance cities—for example, we are collaborating with major e-commerce platforms across Africa that are transforming urban service delivery. But we are also shaping this broader tool kit to tackle the urban impacts of climate change, biodiversity loss, and pollution.
The UrbanShift initiative, led by the UN Environment Programme in partnership with UNDP and many others, is working with cities to promote nature-based solutions, low-carbon public transport, low-emission zones, integrated waste management, and more. This approach focuses not just on implementation, but also on policies and guiderails. The UNDP Smart Urban Innovations Handbook aims to help policymakers and urban innovators explore how they might embed “smartness” in any city.
Our work at the United Nations is driven by the Sustainable Development Goals: 17 essential, ambitious, and urgent global targets that aim to shape a better world by 2030. Truly smart cities would play a role in meeting all 17 SDGs, from tackling poverty and inequality to protecting and improving biodiversity.
Coordinating and implementing the complex efforts required to reach these goals is far more difficult than deploying the latest app or installing another piece of smart street furniture. But we must move beyond the sales pitches and explore how our cities can be true platforms—not just technological ones—for inclusive and sustainable development. The well-being of the billions who call the world’s cities home depends on it.
