“I just want to say one word to you. Just one word.”
“Yes, sir.”
“Are you listening?”
“Yes, I am.”
“Plastics.”
“Exactly how do you mean?”
“There’s a great future in plastics. Think about it. Will you think about it?”

With apologies to my millennial friends, I can’t help but date myself with this iconic example of unsolicited advice given by Mr. McGuire to Benjamin in The Graduate. It captures the thing that bugs me the most about policy think tanks—their habit of providing wholesale unsolicited advice. Think tanks often conjure questions they presume to be relevant, analyze them, and then dispense policy recommendations to unknown audiences.

There’s nothing less appealing than unsolicited advice—and unsolicited policy advice, even when well-intentioned, undermines the recipient’s problem-solving journey and often results in frustration. The advice typically focuses on the desired outcome, not the process one must undertake to get there. Even worse, the adviser bears no responsibility for the outcome. Offering solutions without investment, the adviser risks nothing while the recipient grapples with the potential consequences of acting on the counsel. How exactly was Benjamin supposed to manifest the potential of plastics?

We’ve been known to do this at the Lincoln Institute. Take the example of land value capture: For decades, we’ve advised local governments to use this land-based financing tool to mobilize revenue that can help pay for urban infrastructure. We’ve suggested to municipal funders that they should underwrite loans against future revenue captured from land value increments. We’ve written papers to introduce governments and funders to the concept, described multiple land value capture tools they can use, and produced case studies of best practices in places like São Paulo. But we haven’t often dug in with practitioners to help them decide which land value capture tools are best for their circumstances and learn with them as they adopt and deploy them. That is about to change.

Before I explain how, let me suggest that another useless kind of advice is the “best practice.” Advocating “best practices” to solve complex social, economic, or environmental problems ignores the context surrounding the challenge at hand, does not account for the resources or capacities of people and organizations trying to adapt someone else’s successful approach, and often leads to frustration and inefficiency when the prescribed solution doesn’t align with reality. Best practice thinking stifles innovation and creativity, discourages exploration and experimentation, and often overlooks more appropriate and effective solutions. And who knows if the practice is “best” anyway?

The world is dynamic, and context matters. Relying solely on established norms promotes passive acceptance rather than fostering an environment where individuals question assumptions and actively engage in solving problems. Rather than blindly adhering to “best practices,” a better strategy for tackling complex problems lies in understanding context and adopting a principles-based approach. This champions adaptability and encourages customized solutions to address the unique nuances of each challenge. It compels individuals to weigh various options and make informed decisions grounded in evidence and logic.

So how does this relate to the work of the Lincoln Institute? This fall, with our partner Claremont Lincoln University (CLU), we launched the Lincoln Vibrant Communities program. This new undertaking embodies our best thinking about how to traverse the gap between theory and practice. It prioritizes leadership, action, collaboration, and tangible results. It is a bold and innovative initiative that seeks to transform the way we work, learn, and act together to solve the vexing challenges that cities of all sizes face.

Many communities, particularly those facing economic hardship, lack the capacity (financial and human resources) to implement ambitious development plans. Bureaucratic red tape, outdated regulations, and deeply ingrained power structures impede progress and stifle innovation. Frequently, a lack of trust between residents and local leaders, coupled with limited opportunities for meaningful participation, undermines the effectiveness of development initiatives. More often than not, pressure to produce immediate results leads practitioners to focus on quick fixes rather than long-term, sustainable solutions.

Over the coming decades, we will train a new generation of leaders and equip them with the skills, tools, and resources to transform their cities. We will help these leaders engage cross-sector teams in their communities that can work with residents to take ownership of their futures by solving complex problems collectively. Lincoln Vibrant Communities will furnish the training, tools, resources, and support needed to turn ideas into reality.

And we intend to deliver at scale. Our new initiative draws inspiration from the best leadership development and challenge-based training programs we’ve seen, including the Center for Community Investment’s Fulcrum Fellow and Community Catalyst programs and NeighborWorks America’s Achieving Excellence program. It draws on the superpowers of both CLU and the Lincoln Institute—adapting CLU’s leadership training curriculum and relying on the institute’s deep well of research, policy tools, and expertise.

Lincoln Vibrant Communities begins by identifying and training emerging leaders from diverse backgrounds and sectors. These individuals will complete an intensive six-month leadership development program focused on understanding the complexities of urban challenges, building collaborative leadership skills, developing strategic planning and implementation capabilities, and learning how to leverage community assets and resources. After completing their training, these leaders will return to their respective cities and recruit diverse teams of people representing the public, private, and civic sectors. This cross-sector collaboration is vital for addressing complex challenges that demand multifaceted solutions.

Each team will identify a major challenge their city faces. This could encompass a range of issues, from economic revitalization and affordable housing to environmental sustainability and public safety. The teams will then return for comprehensive team-based training over an additional six months that will equip them with tools and policies developed by the Lincoln Institute; this training will provide a framework for addressing their challenges and building sustainable solutions. With the guidance of experienced coaches, the teams will develop detailed action plans. The teams will then return to their communities and embark on the journey of implementing their plans. Throughout this 18-month process, the teams will receive ongoing support and, most important, coaching from the program to ensure they stay on track and overcome any obstacles they may encounter.

Lincoln Vibrant Communities has the potential to be a game-changer in the field of community and economic development. By traversing the space between theory and practice and empowering local leaders to act, the program is designed to produce concrete improvements in participating cities. By tackling major challenges head on, the teams will make a real difference in the lives of local residents. Additionally, the program will build the capacity of local leaders and communities to design solutions for complex challenges that can be deployed again and again. The skills and knowledge gained through Lincoln Vibrant Communities will have a lasting impact, enabling communities to continue making progress long after the program concludes.

This program will culminate in a growing, curated network of dedicated community problem-solvers. Our approach cultivates innovation by prioritizing comprehension and adaptation over rote implementation. It nurtures a spirit of continuous learning, prompting individuals to reflect on their experiences and refine their problem-solving strategies.

Lincoln Vibrant Communities is not just about solving problems; it is about building a movement of empowered leaders who are committed to creating vibrant, sustainable, and equitable cities. By bridging the gap between theory and practice, we can unleash the full potential of our communities and create a brighter future for all.

In the spirited cultural debate over the possibilities and risks of artificial intelligence, the imagined pros and cons have tended toward the sensational. There’s been little mainstream attention paid to the technology’s potential impact on the everyday tasks that keep our cities humming—things like construction permit reviews, development application processes, and planning code compliance enforcement. But the needs in those areas are quite real, and experiments to apply newer AI breakthroughs to these kinds of operations are already well underway. Municipalities large and small, from Florida to New England, and Canada to Australia, have announced AI-related pilots and other exploratory efforts.

While the approaches vary, the challenges are practically universal. Determining whether proposed construction or development projects meet all land and building codes is a detail-intensive, often slow process: It can be confusing for applicants and require extensive back-end work for municipalities and other authorities. The hope is that AI can help make that process—or “the tedious parts of city planning,” as the publication Government Technology bluntly put it—speedier and more efficient, as well as more accurate and comprehensible. Ideally, it would even allow planning departments to streamline and reallocate resources.

But as city officials working with the new technology make clear, there’s a long way to go to get to that point. And given that some of AI’s most publicized moments to date involve embarrassing failures (such as Google’s AI search tool advising users on the benefits of eating rocks and adding glue to pizza), they are proceeding with caution.

There’s often a “hype cycle” between a new technology’s early promise and its eventual reality, cautions Andreas Boehm, the intelligent cities manager for Kelowna, British Columbia, a city of about 145,000. His team is specifically charged with seeking new opportunities to leverage tech innovations for the city and its residents. Despite a lot of chatter, we still haven’t seen many “concrete, tangible examples” of AI as a “transformative” force in planning systems, Boehm says. But we may start to see real results soon.

Canada is experiencing a housing shortage, Boehm notes, and moving faster on new construction could help. The permitting pipeline is clogged with inquiries from current property owners about zoning and code issues for more routine projects. For a few years, Kelowna has been using a chatbot to answer common questions, Boehm says. That has helped, but the more recent “generative” version of AI can handle a much broader range of inquiries, phrased in natural language, with precise and specific responses. So Kelowna began working with Microsoft to build a new and much more sophisticated version of the tool incorporating Microsoft’s Copilot AI functionality, which they now use to aid permit applicants.

Boehm says the Intelligent Cities team and its consultants worked with a range of residents (including those with no permitting knowledge) as well as experienced builders to develop the tool; it can give high-level responses or point to specific code provisions. It has notably streamlined, and sped up, the application process. “It frees up our staff time” because fewer questions need to be addressed by staff early in the process, Boehm says. “So now they can focus on processing applications that are coming in. And often these applications are much better quality because people are using these AI tools as they’re putting these applications together, and getting all the information they need.”

On the other side of Canada, the city of Burlington, Ontario, near Toronto, has been developing generative AI tools in collaboration with Australian property and tech firm Archistar. Chad MacDonald, Burlington’s chief information officer (and previously executive director of digital service), says Burlington, population 200,000, also faces a housing crunch. With little space available for single-family housing construction, the city’s focus is on improving the process of handling larger projects, including industrial and commercial proposals, with an eye toward creating a single platform that would work for all kinds of projects. The system the city is developing aims to integrate not only local zoning and bylaws, but also the Ontario Building Code, which affects all structures in the province.

Testing this system involves checking whether it correctly assesses previously submitted plans whose outcome is known. This process also trains the AI. “Every time we correct an inaccuracy in the algorithm, it actually makes it smarter,” MacDonald explains. “So the next time it gets more and more accurate.” And if the proposed solution to one permit problem could create two more problems in the application, the system is designed to point that out immediately, avoiding a lengthy resubmission process. An “extremely successful” round of testing was completed in May, MacDonald says, and he expects the city’s use of the technology to expand.

MacDonald envisions the technology advancing to the point of creating code-compliant designs. But won’t that put engineers and architects out of business? He counters that it’s vital to keep humans in the loop. “This is about speeding up these really mundane processes,” he says, “and then allowing these very highly educated and specialized experts to focus on the things they really need to focus on.”

In Honolulu, expanding the use of AI tools is part of a more sweeping tech-plan upgrade to address a significant permitting backlog—in 2021, the city’s mayor declared the process “broken” and committed to an overhaul. In 2022, a permit prescreen process involved “an intolerable six-month wait” to reach a reviewer, says Dawn Takeuchi Apuna, director of Honolulu’s Department of Planning and Permitting. The city added an AI bot that was able to review some of the prescreen checklist items in a newly streamlined process, and it helped cut that wait to two or three days. That success helped lead to a more expansive generative AI pilot with Chicago-based startup CivCheck, a relationship Takeuchi Apuna expects to continue.

“We have learned that there are enormous possibilities of AI in our business processes,” she says, “and that the most important piece is the people that are using it.” She emphasizes that this is just part of an overhaul that also includes better staff training and improved communication with applicants. “It’s a value that you must bring and continue to enforce as part of AI in order to get the best results.”

While these early results are promising, AI still presents plenty of challenges and wildcards. Some of the startup’s promising, powerful generative AI tools are untested. And as MacDonald points out, the technology isn’t cheap. There’s also a need to set standards around what data the process collects and how it can be used. (Kelowna, for example, is working with the nonprofit Montreal AI Ethics Institute on policy and guidance issues.) And, of course, there are broader public concerns about giving too much control to an automated tool, however seemingly intelligent and teachable that tool may be. “It’s not going to replace people,” Boehm says. “We’re never going to just issue you a building permit from an AI bot.”

In fact, he continues, that concern could be considered an opportunity, if cities use AI thoughtfully and transparently. Although government is often opaque and thus treated with skepticism by many, AI “is a great opportunity to demystify government,” Boehm says. “It [can increase the] understanding that this is really about people in the end and supporting them.” In other words, in the best-case scenario, AI might improve a knotty but vital bureaucratic process by giving it a more human touch.

CAMBRIDGE, MA—The Lincoln Institute of Land Policy has released its newest book, City Tech: 20 Apps, Ideas, and Innovators Changing the Urban Landscape, by Rob Walker.

In this thoughtful, inquisitive volume, Walker investigates technologies that have emerged over the past few years and their implications for planners, policymakers, residents, and the virtual and literal landscapes of the cities we call home. Featuring a foreword by tech journalist Kara Swisher and an afterword by urbanist and futurist Greg Lindsay, the book explores the role of technology in our rapidly urbanizing world.

Experts predict that up to 80 percent of the population will live in cities by 2050. To accommodate that growth while ensuring quality of life for all residents, cities are increasingly turning to technology, from apps that make it easier for citizens to pitch in on civic improvement projects to designs for smarter streets and neighborhoods.

“We’re on a complicated journey; our decisions can set us off in surprising directions, and opinions may differ on how to navigate the challenges ahead,” writes Walker, a Fast Company columnist and New York Times contributor, in the book’s introduction. “But based on the examples in this collection, it seems clear that collaboration, creativity, and an openness to new ideas are the keys to getting where we need to go.”

City Tech is a chronicle of the recent rise of urban technologies, featuring firsthand reflections from the founders, innovators, and researchers closest to the work and from the planners and other officials who are putting these tools into practice on the ground. It’s also a source of essential questions: What are the ethical implications of smart cities? How can cities keep up with the rapid evolution of driverless vehicles? Is building skyscrapers out of wood a viable climate solution?

“If the last decade of urban tech has been a dress rehearsal, then the curtain is now rising on the most momentous decade of change most cities have ever had to face,” writes Lindsay in the book’s afterword. “It is our turn to formulate what we demand from our technologies, versus the other way around.”

City Tech, a curated collection of newly updated columns originally published in Land Lines, the magazine of the Lincoln Institute, follows last year’s release of Mayor’s Desk by Anthony Flint, a compilation of interviews with mayors from five continents who shared their strategies for tackling global challenges at a local level. Together, the books provide tangible examples of how cities across the world have mobilized to implement innovative land-based solutions for some of society’s most critical challenges.

City Tech is available for purchase on the Lincoln Institute website. For review copies, contact Kristina McGeehan at kmcgeehan@lincolninst.edu. City Tech is distributed by Columbia University Press.

A medida que la ciudad crece y los efectos del cambio climático se tornan más evidentes, también crece la importancia de los árboles urbanos. Los árboles brindan la sombra que tanto necesitamos, eliminan la contaminación del aire, absorben el carbono e incluso aumentan los valores de los bienes inmuebles. Pero suele pasarse por alto un elemento: una cosa es plantar muchos árboles, pero otra es preservarlos.

Durante años, la tecnología ha desempeñado un papel importante en los esfuerzos de rastrear, mapear y cuantificar los impactos globales de los paisajes arbóreos, desde lo ambiental hasta lo económico, tema que se trató en esta columna en 2018. Pero, desde entonces, surgieron y evolucionaron nuevas tecnologías, y algunas de las más interesantes se centran no solo en los impactos políticos de alto alcance, sino también en el tema crucial del mantenimiento a largo plazo. Si se espera que la población de árboles urbanos perdure, el riego adecuado y oportuno, sobre todo para los árboles más jóvenes, debe ser parte de la planificación. Y, cada vez más, las ciudades están aprovechando herramientas de datos sofisticadas para fomentar y permitir la participación de la ciudadanía en la preservación de los árboles urbanos.

Por ejemplo, CityLAB Berlin, una organización sin fines de lucro de innovación tecnológica de Alemania que aplica datos a los problemas urbanos tiene varios proyectos en curso. En los últimos años, Berlín, una de las ciudades con más árboles de Europa, perdió el 20 por ciento de sus ejemplares a causa de las altas temperaturas y la escasez de lluvias. Esto se debe, en parte, a que supervisar y preservar árboles individuales puede ser una carga ardua y complicada para los gobiernos municipales. Así que, en 2020, CityLAB lanzó Gieß den Kiez (Regar el barrio), una plataforma digital que puso a disposición del público en general datos del gobierno sobre árboles. Esto permitió que la ciudadanía pudiera informarse sobre las necesidades de riego de los árboles locales y comprometerse a ayudar. “La aplicación se desarrolló con base en las necesidades de nuestra comunidad”, expresó por correo electrónico Yannick Müller, directora de asociaciones estratégicas de la organización.

La cantidad de datos disponibles fue una revelación: los proyectos de los gobiernos habían detallado y mapeado con anterioridad cientos de miles de árboles. CityLAB, un proyecto de Technologiestiftung Berlin, fundación financiada por la Cancillería del Senado de Berlín, combinó esto con otros datos, como cifras de lluvias, para crear un mapa que asocia la actividad de riego con las necesidades específicas para cada especie para los árboles de la ciudad. Los comentarios de la ciudadanía comprometida con los árboles ayudaron a darle forma al desarrollo de la plataforma. Algunas personas ya habían adoptado y empezado a preservar árboles de forma particular. “Sienten que son sus propios árboles”, dijo la gerenta de CityLAB Berlin, Julia Zimmermann. La ciudadanía también tuvo ideas sobre cómo utilizar el sistema de bombas de agua existente en la ciudad y mejorar su asequibilidad.

“Los usuarios, grupos e iniciativas pueden interactuar entre sí a través de una herramienta de chat, que también nos permitió comunicar y recopilar opiniones”, explicó Müller. Aparte de resolver errores pequeños, esto inspiró nuevas funciones, como una que muestra la ubicación y el estado de las bombas de agua. A su vez, permitió designar “cuidadores” para árboles específicos, que se comprometen a supervisar y regar con regularidad. “La adición de esta función pequeña permite a los ciudadanos hacer uso de sus recursos de forma más dirigida”, expresó.

Según Müller, en 2021, la ciudad de Leipzig adoptó la herramienta, y algunas otras municipalidades alemanas siguieron sus pasos. Los números de los usuarios no paran de crecer, y más de 3.500 ciudadanos se registraron como cuidadores de más de 7.500 árboles adoptados.

Más allá de esto, los esfuerzos de Gieß den Kiez siguen siendo un complemento de la política pública. “Sin embargo, la plataforma logra generar cada vez más conciencia sobre las adaptaciones climáticas, anticipándose a las futuras olas de calor”, sostiene Müller. En Berlín, por ejemplo, “suscitó un debate entre las diferentes autoridades de distritos locales sobre hasta qué punto la ciudadanía debería participar en el cuidado de los árboles de la ciudad y si ese uso del agua es adecuado” (Según Müller, lo es, si se consideran los costos de plantar árboles nuevos y los numerosos beneficios comprobados para la salud y el medioambiente que ofrece un follaje urbano robusto).

Una de las inspiraciones que CityLAB Berlin ha citado es el mapa de árboles de la ciudad de Nueva York (NYC Tree Map), una herramienta digital que se remonta al 2016, y que ya tiene registrados alrededor de un millón de árboles. En un comunicado de prensa de 2022, el Departamento de Parques y Recreación (NYC Parks) declaró que “NYC Tree Map es el mapa más integral y actualizado de árboles vivos en el mundo”. “El mapa, que está integrado directamente con la base de datos forestales de los parques, le brinda a la ciudadanía el mismo acceso en tiempo real al bosque urbano que los silvicultores de parques tienen en el terreno”. Esto permite que las personas de Nueva York “interactúen de forma digital” con la población forestal de la ciudad en los cinco distritos; por ejemplo, pueden supervisar la inspección más reciente de un árbol, con la fecha y la identificación de la inspección.

“Nuestro NYC Tree Map permite que los amantes casuales de árboles identifiquen ejemplares fácilmente, comuniquen sus inquietudes e informen sobre su cuidado”, explicó por correo electrónico Nichole Henderson, directora de la Administración de NYC Parks. “Grupos y personas registran en el mapa sus actividades de cuidado de árboles, como el riego, la eliminación de basura, el cultivo de la tierra y la cobertura con mantillo”.

Varios grupos usan el mapa para coordinar esfuerzos de mantenimiento y administración más ambiciosos. A modo de ejemplo, Hernderson menciona el Jackson Heights Beautification Group, una organización ambiental y artística de Queens; Trees New York, una organización profesional de larga trayectoria que capacita a “podadores de la ciudad”, entre muchas otras actividades, y la organización Gowanus Canal Conservancy, cuyos proyectos incluyen esfuerzos de “ciencia comunitaria” como experimentos sobre la captura y el uso del agua de lluvia. Y el mapa de árboles es clave para la campaña de mayor alcance de NYC Parks, Let’s Green NYC (Llenemos de verde a NYC), que publica “actividades de cuidado de árboles en las calles de toda la ciudad con socios comunitarios y permite que los voluntarios vean el impacto visible, cómo están contribuyendo directamente con el cuidado de la floresta urbana”, dijo Herderson.

En otras ciudades importantes se están llevando a cabo iniciativas similares. El Departamento de Transporte del Distrito (DDOT) de Washington, DC, mantiene un mapa de árboles digital que promueve la participación ciudadana (por ejemplo, para que informen el oscurecimiento de las hojas o el daño de insectos, así como los árboles que necesitan agua). El mapa de árboles se lanzó con un foco especial en preservar 8.200 árboles plantados en 2017. Otro ejemplo es la aplicación Adopt-A-Tree en Atenas, que permite a los ciudadanos asumir la responsabilidad del riego de árboles individuales de la ciudad durante los meses secos del verano. Y las entidades como CityLAB Berlin siguen innovando: su nuevo proyecto Árboles Cuantificados (QTrees) aspira a desarrollar un sistema de predicción respaldado por inteligencia artificial, haciendo uso de bases de datos y sensores para identificar los árboles urbanos en riesgo de secarse. Ya se está probando un prototipo, y el plan es lanzarlo este año.

Zimmermann, de CityLAB Berlin, reconoce que fue difícil demostrar con precisión el impacto de estos esfuerzos. “Esto se debe a la naturaleza de la naturaleza”, dijo. Los árboles se adaptan con lentitud, así que estimar los efectos de los programas de riego podría requerir años de supervisión del crecimiento y la salud. Pero el tablero de datos del proyecto ilumina los patrones de riego, y mostró que las cantidades de riego aumentaron desde que el programa comenzó, y, casi con certeza, contrarrestaron los efectos de la sequía. “Así que el proyecto genera, por lo menos, un mejor entendimiento y cuidado de los espacios verdes urbanos”, añadió. En algunos casos, ha inspirado a gobiernos locales a apoyar a voluntarios, al brindarles material y lineamientos para prácticas de riego óptimas.

En una encuesta reciente sobre la valoración sorprendentemente duradera de las personas por lo arbóreo, la historiadora y autora, Jill Lepore, observó que “los árboles son los nuevos osos polares, la imagen que es tendencia en el movimiento medioambiental”. Ahora tenemos la ciencia y la tecnología para entender y cuantificar el valor de los árboles más allá de lo estético. “Si a nuestros ancestros les pareció inteligente y necesario talar los bosques rápidos, es incluso más necesario que sus descendientes planten árboles”, escribió la paisajista Andrew Jackson Downing en 1847. “Permitamos que todas las personas, cuyas almas no sean un desierto, planten árboles”. De acuerdo. Pero, también tenemos la obligación, y la tecnología, para preservarlos.
