Rethinking Smart Cities

Reviewed by Jungwoo Chun, Massachusetts Institute of Technology

What is the 15-minute city concept and how can it be combined with future technologies in cities to enhance livability and achieve decarbonization goals?

Rethinking Smart Cities

Rethinking Smart Cities by Zaheer Allam and Yusra Raisah Takun, 2022, Edward Elgar Publishing Limited, 180 pp.

In Rethinking Smart Cities, the authors explore what they call the 15-minute city concept—which promotes human livability by ensuring that residents have access to the basic needs within the 15-minute travel time either by walking or cycling. They argue that this concept will gain more prominence when combined with future technologies in cities such as 6G, AI applications and digital twins. Their vision is that this approach will not only enhance livability but also help achieve other goals like global commitments to achieve decarbonization.

The key in my view is their effort in emphasizing that technology cannot be decoupled from the human element (i.e., beyond a technocentric approach) when urban residents ought to participate in the informed process of improving resilience and livability in cities. Technology is not just an application of a product—it’s a network of systems—the socio-political, economic and cultural systems.

The book conveniently introduces what a smart city is and offers a historical landscape of basic technological advancements in cities. Yet, “smartness” is not everything. Today, cities face numerous challenges including the ability to cope with emerging smart technologies (i.e., both the physical infrastructure and social aspects). Relatedly, the next several chapters provide an overview of some of the key issues smart cities ought to address—such as sustainability, inclusivity, efficiency and data security—as an opportunity to embed collaborative problem-solving in the planning process. Finally, the last few chapters offer a vision for what’s emerging: 6G technologies (and IoT), a 15-minute city planning concept and augmented automation.

The book leaves incredible room for afterthought. We as implementers or users of smart technologies in cities ought to think carefully about how we can participate meaningfully in the planning process—and collaboratively anticipate future challenges or vulnerabilities—as new technologies continue to emerge and become integrated into urban livelihoods. Perhaps truly “smart” cities will have figured out public participation and informed decision-making in future planning practices.

Sustainability Made Simple: Small Changes for Big Impact

Review by Jungwoo Chun, Massachusetts Institute of Technology 

 What does sustainability mean to individuals in their day-to-day practice? How can individuals engage more directly and realistically with the idea of sustainability?

Sustainability Made Simple

Sustainability Made Simple: Small Changes for Big Impact, by Rosaly Byrd and Lauren DeMates, Rowman & Littlefield, 2019, 216 pp.

Sustainability Made Simple is designed for those who are interested in learning what sustainability means to them. Sustainability is often linked with climate change and other environmental issues. What it means to individuals and day-to-day practices is less frequently discussed in much detail. Rosaly Byrd and Lauren DeMates do just that–putting people as agents of change, they offer ways for individuals to support the collective efforts towards sustainability. The book is for everyone who wishes learn how they can engage more directly and realistically with the concept of sustainability and the environment.

The book is organized in two parts. In part 1, the authors introduce the environmental problems we face collectively (i.e., air and water pollution, deforestation and climate change); provide examples of how governments, companies and other societal organizations are transitioning toward sustainability (i.e., making commitments and technological investments); and underscore why individual action is vital. Besides the fact that more than 60 percent of greenhouse gas emissions are contributed by household consumption, the authors describe what they call a shift towards a culture of sustainability that essentially supports collective efforts. They emphasize the importance of individuals taking small steps such as making consumption decisions more carefully, buying more sustainably grown products or actively monitoring electricity and water usage at homes. Part 2 offers various examples of these small changes individuals can achieve–opportunities to integrate sustainability into day-to-day practices.

What is most fascinating is how much of what appear to be low-hanging fruits can in fact be completely unnoticed or ignored. The detailed list of practices (ranging from cutting down on foods with the biggest environmental footprints to going paperless) provides an opportunity for individuals to perform a self-audit and identify what else can be done on a daily basis. Part 2 essentially offers a detailed recipe for individuals who desire to learn and apply the practices to their daily routines. While the book provides examples from multiple contexts (often international), it would be even more interesting to observe examples of how an accumulation of individual efforts engenders a culture of sustainability that in fact supports national or local-scale societal transitions towards sustainability.

The good news is that transitions to sustainability are still optimistic and easily relatable. The detailed accounts of what we can do as individuals are a testament to how the ideas of sustainability have evolved over time. As a reader, my hope is that more people around the world can invest 5-10 minutes of their time and try out a few daily practices described in the book. The combined effects cannot be readily measured or studied, but I have little doubt that the impacts will be enormous.

A Better Planet: 40 Big Ideas for a Sustainable Future

Reviewed by Aria Ritz Finkelstein, Massachusetts Institute of Technology

How can systems thinking about democracy and inclusion, about innovation and creativity; technical solutions; and building social equity and environmental justice through community programs and initiatives promote sustainability? 

A Better Planet

A Better Planet: 40 Big Ideas for a Sustainable Future, edited by Daniel C. Esty, Yale University Press, 2019, 416 pp.

Esty gathers the thoughts of some truly brilliant and knowledgeable thinkers and scholars in the field of sustainability. The collection of proposals is too broad to even begin to do justice to in such a short review. The authors’ stances run the gamut from a belief in the power of technical innovation to an insistence on deep ecology and the intrinsic value of “nature.” Still, given the book’s title, it will not surprise the reader that the attitude throughout is upbeat. Yes, the chapters describe enormous challenges, but these writers take them on with a shared confidence that these challenges can be—will be—overcome.

The essays range across topics as disparate as Thomas Rashad Easley’s discussion of “hip-hop forestry” as joining young students with foresters and Cary Coglianese’s argument for the use of machine learning in environmental management. Some, Susan Biniaz on international agreements, for example, take on global environmental governance, while others, such as Meha Jain and Balwinder Singh on no-tillage farming, zoom into a closer frame of view.

The essays cover systems thinking, democracy and inclusion, innovation and creativity. All of these terms risk becoming buzzwords, and because of the sheer number of the essays none can dive too deeply into its subject. However, each bite-sized chapter offers enough to introduce the reader to the problem it addresses, to explain what its stakes are, to outline the broad conversation already being had around it, and, usually, to offer a path forward and even a way to join in.

The sections vary in tone and orientation, in ways not entirely surprising. For example, the “Innovation and Technology” section gathers pieces that place their optimism in technical solutions. The “Society, Equity and Process” pieces, as a group, tend to focus more on building social equity and environmental justice through community programs and initiatives. As a group they manage to concisely and engagingly lay the historical groundwork needed to grasp the issues they are tackling, explain why they are important, and suggest at least one path forward. Another thing the writers have in common: Each is almost unflaggingly optimistic.

The collection might benefit from a more structured conversation between the pieces, one that would bring the ideologies and assumptions behind them, and the implicit conflicts between them, into sharper relief. The book shies from facing the full complexity and difficulty of challenges—especially intensely political ones—head on. On the other hand, the way the essays stand alone demonstrates faith in the reader’s capacity to grasp without handholding.

The book is a conversation-starter. This moniker is often a pejorative one, but here it is the book’s strength. On this point, Esty is explicit: “Indeed, our goal is not just to contribute to the substance of the policy dialogue over our environmental future but also to demonstrate how to have such a conversation. So please join us in this debate.” And, at the end of the collection, he invites the reader to participate in an online conversation, an exchange into which the book is only one entrance. The book is welcoming. Together, its essays add up to an entryway into those discussions that have the potential to shape the world to come.
