A medida que la lluvia se acumulaba sobre el techo de 14.000 metros cuadrados de un centro de tránsito en uno de los vecindarios más inundables de Worcester, Massachusetts, el panorama se hacía nefasto. Pero, en vez de transformarse en una amenaza, esa agua pluvial se escurrió en un revoltijo de equináceas moradas, eupatorias púrpuras, salvias rusas y otras plantas tolerantes a inundaciones y sequías que crecen entre el complejo y la avenida Quinsigamond, que está cerca de allí.
El centro de tránsito, construido sobre un terreno abandonado acondicionado, representa una inversión de US$ 90 millones para esta pequeña ciudad. Los elementos de infraestructura verde, como ese jardín de biofiltración que absorbe agua de lluvia, se consideraron necesarios, dice William Lehtola, presidente del comité asesor de la Autoridad Regional de Tránsito en Worcester: “Queremos ofrecer el mejor ambiente posible para la ciudad, nuestros clientes y empleados”, dijo. “No solo en los autobuses, sino también en las instalaciones”.
Con la labor continua y agotadora de recuperarse de las graves pérdidas económicas y de población que Worcester y su vecina Providence, Rhode Island, sufrieron desde su auge como fabricantes, el enfoque ecológico toma impulso en estas antiguas ciudades industriales pequeñas. A pesar de los desafíos, que van desde las restricciones financieras hasta la infraestructura deteriorada, muchas de estas ciudades se dieron cuenta de que invertir en infraestructura verde (y a veces forzarla) ofrece múltiples beneficios. Algunos proyectos, como jardines pluviales o de biofiltración, agricultura urbana y plantación de árboles, ya sean introducidos a pequeña escala o implementados en toda la ciudad, son una forma efectiva de revitalizar espacios públicos, gestionar agua pluvial, mejorar la salud pública y lidiar con los impactos del cambio climático, desde el aumento de las temperaturas hasta las inundaciones.
“La infraestructura verde puede abordar muchos desafíos, y también ofrecer servicios”, dice el profesor Robert Ryan, presidente del Departamento de Arquitectura Paisajística y Planificación Regional de la Universidad de Massachusetts, Amherst. Ryan ha liderado cursos sobre antiguas ciudades industriales, como Worcester. “Las ciudades como Worcester y Providence son lugares ideales para este enfoque”. Cultivar este cambio no siempre es sencillo. Si bien los nuevos códigos, las normativas y la conciencia ambientales aumentaron la frecuencia de los proyectos de infraestructura verde, suelen seguir coexistiendo con estructuras y partes de la calle de una época anterior, cuando las vías fluviales cercanas eran cloacas de hecho y el asfalto era la elección predilecta para las mejoras urbanas.
A medida que las antiguas ciudades industriales del país implementan proyectos y estrategias de infraestructura verde, lidian con una realidad importante: no se pueden volver a crear así como así. Sin embargo, sí pueden adaptarse y evolucionar.
Nueva Inglaterra como nueva
Worcester se encuentra en una zona de colinas en el centro de Massachusetts y alberga unas 185.000 personas. El pico de población fue en 1950, con 203.486 personas, y cayó a unas 161.000 en 1980.
Worcester siempre fue el centro económico del condado de Worcester, donde se encuentra. Pero se ganó el apodo de “Corazón del territorio autónomo” gracias a las conexiones con Boston (por tren en 1835) y con Providence (por el canal Blackstone en 1828 y el tren Providence & Worcester Railroad, a fines de la década de 1840); así, adquirió importancia como centro industrial y de transporte. Se hizo conocida por las máquinas-herramientas, productos trefilados y telares mecánicos.
Providence, ubicada a orillas del río Providence, en el cabo de la bahía Narragansett, siguió un camino similar, pero en un entorno diferente. La ciudad costera alberga unas 180.000 personas. Es más que el récord mínimo del s. XX, de 156.000 en 1980, pero mucho menos que su pico, de más de 252.000, en 1940. Providence es la capital del estado y se convirtió en el centro neurálgico de fabricación luego de la Guerra de Independencia, con fábricas que producían en masa joyas, textiles, objetos de plata y maquinarias, y los enviaban desde el puerto. En un punto, fue una de las ciudades más ricas del país.
En ambas ciudades, la actividad industrial y la población terminaron por menguar y, junto con la suburbanización, dejaron secciones vacías que antes eran bulliciosos centros urbanos (ver Figura 1). Pero, tal como sucede con muchas antiguas ciudades industriales, poco a poco la gente redescubre los recursos que ofrecen estas comunidades. Como explican Alan Mallach y Lavea Brachman en el informe Regenerating America’s Legacy Cities (Regenerar las antiguas ciudades industriales de Estados Unidos) del Instituto Lincoln, algunos de estos recursos son bases de empleo en el centro, vecindarios estables, redes de transporte multimodal, facultades y universidades, tiendas locales, edificios y zonas históricos, e instalaciones para arte, cultura y entretenimiento (Mallach 2013).
Por ejemplo, Providence es sede de la Universidad Brown, la Escuela de Diseño de Rhode Island, la Universidad de Rhode Island y Johnson & Wales. Worcester alberga más de una decena de instituciones de educación superior, como la Universidad Clark, el College of the Holy Cross, el Instituto Politécnico de Worcester y la Facultad de Medicina de la Universidad de Massachusetts. Ambas ciudades poseen hospitales importantes y espacios para espectáculos. Y ambas ciudades han revitalizado sus centros con proyectos distintivos.
Providence logró renovar su imagen como centro artístico y cultural a principios de los 90. En una labor masiva de infraestructura verde, exhumó el río Providence, nacido de la confluencia de los ríos Woonasquatucket y Moshassuck, que hacía mucho tiempo habían sido enterrados bajo estacionamientos y vías de tren, y sus orillas bordeadas con parques y senderos peatonales. El alcalde de ese entonces, Vincent “Buddy” Cianci Jr., dijo: “El río debe ser una parte integral de la ciudad. No lo tapen, no lo bloqueen, no lo contaminen. Celébrenlo y úsenlo”. Este trabajo masivo cambió la personalidad del centro, que pronto comenzó a atraer nuevos proyectos de desarrollo, como renovaciones ambiciosas de molinos vacíos, y también nuevos residentes y empresas.
Worcester está reemplazando el fallido centro comercial del centro con el redesarrollo CitySquare de uso mixto, una inversión de US$ 565 millones. Este volverá a conectar el distrito empresarial central con otras partes pujantes de la ciudad, como Washington Square (donde se encuentra la renovada Union Station), los restaurantes de Shrewsbury Street y Canal District, que está de moda. De hecho, el informe Revitalizing America’s Smaller Legacy Cities (Revitalizar las antiguas ciudades industriales más pequeñas de los Estados Unidos) del Instituto Lincoln mencionó a Worcester por su “alto rendimiento” entre otras ciudades del mismo tamaño (Hollingsworth 2017). Algunos factores que incidieron en esta decisión son la cercanía a Boston y el fácil acceso por tren comercial, líderes con energía y habilidades para revitalizar la ciudad y el proyecto CitySquare. Providence no se incluyó en el informe del Instituto Lincoln, pero sus labores de revitalización fueron destacadas por organizaciones como la Asociación Americana de Planificación o The New York Times.
Si bien esta fuerza es prometedora, el cambio climático complica todo. En la región Noroeste, el cambio climático se asocia a eventos extremos más frecuentes, como lluvias fuertes e inundaciones, sequías, aire y temperatura del agua más cálidos, cambios en los patrones de circulación en el océano (e impactos relacionados en el clima y la pesca) y crecida del nivel del mar. La ubicación de Providence la hace vulnerable a inundaciones y daños de las tormentas “Nor’easter” y los huracanes que azotan sus costas. Un informe climático preparado en Worcester alude a impactos pronosticados, como “aumento de temperaturas, días con calor más extremo y cambios en los patrones de precipitación”.
“Cierto grado de cambio climático es inevitable; literalmente, no hay nada que podamos hacer sobre eso ahora”, dice Edward R. Carr, profesor de desarrollo internacional, comunidad y medioambiente en la Universidad Clark, en Worcester. “La pregunta es: cuánto podemos lidiar con eso y cómo será en el futuro”.
Donde se unen la revitalización y la preparación
“La lógica más fundamental al pensar en infraestructura verde es crear utilidades de una acumulación masiva de terrenos vacíos para que no sean una plaga y, con suerte, [tengan] un efecto positivo en el barrio”, dice Alan Mallach. “Históricamente, muchas personas tenían la teoría de que un terreno vacío era inútil, a menos que se construyera algo ahí. Pero eso está cambiando. Hay distintas formas de tomar un terreno vacío y hacerlo valioso para la comunidad, ya sea para fines recreativos, para producir alimentos frescos o para tratar el desborde de las cloacas. Hay formas de abordar los terrenos vacíos que no implican construir viviendas u oficinas nuevas”.
Al evaluar las oportunidades de uso del suelo, las antiguas ciudades industriales suelen carecer de poder político o económico para diseñar soluciones efectivas. Pero hay un área en que estas ciudades tienen una ventaja: buscan reinventarse como lugares más saludables y atractivos para vivir; entonces, suelen estar más dispuestas a aceptar proyectos novedosos y creativos. Amy Cotter, directora adjunta de Programas Urbanos del Instituto Lincoln, dice que esto ayudará en la era del cambio climático.
“Si se piensan formas de preparar a las antiguas ciudades industriales para que tengan una participación crucial en un futuro en que el cambio climático afecta a los grandes centros demográficos, la infraestructura verde podría ser una estrategia de revitalización y preparación para el clima”, dice Cotter. “También puede ayudar a los lugares a revitalizarse y lidiar con lo que, de otro modo, sería la plaga de las propiedades vacías”.
Las antiguas ciudades industriales más grandes de todo el país han adoptado un conjunto de opciones con estos objetivos en mente. En Detroit, una labor cabal de infraestructura verde llevó a que en toda la ciudad broten techos verdes, jardines pluviales y un programa de “callejones ecológicos” por el cual las plantas nativas y el pavimento permeable reemplazan los escombros urbanos y el concreto en callejones que antes estaban abandonados. En Cleveland, el distrito regional de cloacas administra un programa de subsidios para infraestructura verde, y se están concretando planes ambiciosos para un parque que ocupará 8 hectáreas de costanera del río Cuyahoga, que antes era industrial. Filadelfia invierte unos US$ 2.400 millones en financiación pública durante 25 años para hacer desde barriles pluviales hasta humedales urbanos para reducir el desborde combinado de las cloacas.
Las antiguas ciudades industriales más pequeñas, con menos de 200.000 habitantes, no siempre llegan a los titulares ni tienen los recursos y la capacidad de emprender proyectos tan grandes, pero muchas realizan labores similares. Worcester y Providence demuestran cómo la infraestructura verde puede ayudar a estas ciudades (una en la costa y una tierra adentro) a recuperarse de los desafíos del siglo pasado y prepararse para las incertidumbres de las próximas décadas.
“La infraestructura verde no solo es una alternativa ambientalista para los sistemas de agua pluvial tradicionales; también puede ayudar a protegernos de los impactos climáticos, como la isla de calor urbana y la erosión costera, y se puede usar en el diseño de las calles para que sean más seguras para ciclistas y peatones”, dice Leah Bamberger, directora de sustentabilidad de la ciudad de Providence. “Providence es una ciudad progresista, y la infraestructura verde es una oportunidad de invertir en empleos ecológicos y al mismo tiempo construir una comunidad próspera y más saludable”.
Encontrar soluciones para el agua pluvial
En los últimos 80 años, la frecuencia de inundaciones se ha duplicado en Rhode Island y el sur de Nueva Inglaterra, y también ha aumentado la magnitud de dichos eventos, según el informe Resilient Rhody: An Actionable Vision for Addressing the Impacts of Climate Change in Rhode Island (Rhody resiste: una visión factible para abordar los impactos del cambio climático en Rhode Island, estado de Rhode Island 2018). Por desgracia, la infraestructura de la región no está a la altura del desafío.
“Gran parte de la infraestructura estatal para agua pluvial se construyó hace al menos 75 años, y se diseñó para tormentas menos intensas”, dice el informe Resilient Rhody. “El cambio climático desafía aun más la capacidad y el rendimiento de estos sistemas de drenaje”.
Carr dice que esto también sucede en la zona de Worcester, y destaca: “Aquí, sencillamente la infraestructura no está hecha para lidiar . . . con lo que se está convirtiendo en normal”.
“La adaptación al clima es muy específica de cada lugar”, dice Ryan, de la Universidad de Massachusetts, quien coeditó Planning for Climate Change: A Reader in Green Infrastructure and Sustainable Design for Resilient Cities (Planificar para el cambio climático: texto sobre infraestructura verde y diseño sustentable para ciudades con capacidad de recuperación), publicado por Routledge. “Para estas ciudades en particular y cualquier antigua ciudad industrial, la pregunta es cómo ubicar el agua adicional que llega con el aumento del nivel del mar y de las precipitaciones”. Ryan destaca que los patrones de desarrollo de vecindarios tendieron a surgir de la ubicación histórica de viviendas de empleados cerca de fábricas y molinos costeros, y dice que las inundaciones también desatan cuestiones de igualdad: “¿Cómo protegen las ciudades a las poblaciones vulnerables en esas zonas bajas?”
Las entidades públicas y privadas están tomando medidas con esta serie de preocupaciones en mente. La coalición Green Infrastructure Coalition, de Rhode Island, compuesta por más de 40 organizaciones sin fines de lucro, planificadores de ciudades, arquitectos, funcionarios electos y otros, trabaja para promover proyectos de infraestructura verde como forma de reducir los problemas de agua pluvial, como inundaciones y contaminación.
La coalición contrata equipos locales para instalar proyectos de infraestructura verde, como un jardín de biofiltración en un parque local, un techo verde o un jardín pluvial, y capacita sobre el mantenimiento a los empleados de obras públicas y otras partes involucradas. “Por ahora son proyectos pequeños, pero parece que la necesidad y el apetito de ellos están creciendo”, dice John Berard, director estatal en Rhode Island de Clean Water Action, que funciona como organizador de proyecto para la coalición. “Vemos que prevalece cada vez más a medida que las tormentas empeoran, y las ciudades se están dando cuenta de que el agua pluvial es una parte muy importante de la gestión efectiva de la ciudad”.
Mientras tanto, la ciudad de Worcester estableció políticas que ayudan a garantizar una buena gestión del agua pluvial. La ciudad regula la escorrentía cerca de humedales y colectores de fango que drenan directamente a humedales o zonas con recursos hídricos. Además, ningún desarrollo o redesarrollo debe tener un aumento neto de tasas de escorrentía, lo cual suele ver nacer sistemas de gestión de agua pluvial en el mismo sitio de desarrollos grandes.
Por otro lado, la ciudad protege el suelo de su cuenca de manera intensiva, para mejorar la calidad del agua potable y compensar parte del territorio que se perdió con el desarrollo, según indica Phil Guerin, director de operaciones hídricas y de cloacas de la ciudad.
Pero Guerin destaca que, debido a la naturaleza urbanizada de Worcester y su geología, es difícil reducir la cantidad de superficies impermeables. “Hay muchas zonas con lecho rocoso poco profundo, un nivel de agua poco profundo, y es una ciudad bastante urbanizada”, dice Guerin.
Combatir el efecto de isla de calor urbana
Hace algunos años, los científicos de la NASA se propusieron comprender la diferencia entre temperaturas en la superficie de las ciudades del Noreste y las zonas rurales circundantes. En la investigación descubrieron que, en un período de tres años, las temperaturas en la superficie de las ciudades tuvieron un promedio de 7 a 9 grados más que las zonas circundantes. En Providence, las temperaturas de la superficie son unos 12,1 grados más cálidas que en el campo circundante (NASA 2010). El hecho de que Providence es compacta ayudó a este efecto de isla de calor, ocasionado porque los edificios retienen el calor y por la infraestructura urbana, como el asfalto.
Cuando se trata de combatir este efecto, la respuesta es evidente, dice Carr, de la Universidad Clark: “Árboles, árboles, árboles. Hay montones de estudios que indican que los mantos urbanos de árboles hacen una diferencia impresionante en el descenso de las temperaturas, mejoran la calidad del aire y, en cierto sentido, ayudan con las inundaciones”.
Según el Departamento de Agricultura de EE.UU., un árbol saludable de 30 metros de alto puede tomar 41.600 litros de agua del suelo y liberarlos al aire en un solo período de vegetación.
En 1907, la ciudad de Providence registró unos 50.000 árboles en las calles, según indica la asociación local sin fines de lucro Providence Neighborhood Planting Program (PNPP). Hoy, la ciudad tiene apenas la mitad: unos 25.500, según el tablero de sustentabilidad en el sitio web de Sustentabilidad de la ciudad de Providence. Se está realizando un inventario de árboles en toda la ciudad.
Con su plan Trees 2020, Providence pretende aumentar el manto de árboles en un 30 por ciento hacia 2020 y plantar 200 árboles cada año. La ciudad se asoció con PNPP; ofrecen subsidios para plantar árboles, realizar los cortes en las aceras y alcorques, y entregar árboles gratis. Además, PNPP y la ciudad ofrecen el programa Providence Citizen Foresters, que ofrece capacitación técnica centrada en el cuidado de los árboles urbanos jóvenes. Desde 1989, PNPP cofinanció la colocación de más de 13.000 árboles en las calles con más de 620 grupos vecinales.
“Si la gente está involucrada y quiere el árbol, es más probable que lo cuide y lo riegue”, dice Bamberger. “Se pueden plantar árboles todo el día, pero si no hay nadie que los cuide y los riegue, no van a durar mucho”.
Ryan hace eco de esta idea, que concluye con la investigación en la que ayudó en jardines comunitarios de Boston y Providence. “A veces hay grupos externos que vienen a las ciudades y vecindarios y dicen qué linda es la infraestructura verde. Pero, a menos que la comunidad la quiera, y quiera mantenerla, no se sostiene bien en el tiempo”, dice. “La infraestructura verde necesita verticalidad en ambos sentidos. Un enfoque de abajo hacia arriba parece tener un impacto a mayor plazo en lo que refiere a la administración y a lograr que los proyectos funcionen”.
En Worcester, una labor sólida de plantación de árboles acabó por convertirse en una historia de éxito a nivel estatal. En 2008 se encontraron escarabajos asiáticos de cuernos largos en Worcester, lo que llevó a una labor masiva de erradicación que acabaría con 35.000 árboles en una zona de cuarentena de 285 kilómetros cuadrados en la ciudad y pueblos adyacentes. Cuatro años más tarde, algunos alumnos de la Universidad Clark comenzaron a estudiar el impacto de la pérdida de estos árboles y notaron que el efecto de isla de calor había aumentado —al igual que las cuentas de calefacción y aire acondicionado— en un barrio que había perdido los árboles.
En 2009 se lanzó una ambiciosa labor de reforestación conocida como Worcester Tree Initiative. La ciudad y el Departamento estatal de Conservación y Recreación (DCR, por su sigla en inglés) se unieron para plantar 30.000 árboles en apenas cinco años, en jardines privados, parques y las calles. El programa recluta administradores vecinales de árboles para que los cuiden y los controlen, y cuenta con el programa de verano Jóvenes Adultos Guardabosques para jóvenes en situación de riesgo.
La asociación tuvo tanto éxito que el DCR la expandió a otras ciudades de Massachusetts mediante la iniciativa Greening the Gateway Cities. Este programa se concentra en áreas dentro de ciudades con un manto de árboles inferior, viviendas más antiguas y mayor población arrendataria. El DCR trabaja con asociaciones locales sin fines de lucro y contrata equipos del lugar para plantar árboles y lograr beneficios ambientales y eficiencia energética. Hoy, este programa está activo en Brockton, Chelsea, Chicopee, Fall River, Haverhill, Holyoke, Lawrence, Leominster, Lynn, New Bedford, Pittsfield, Quincy, Revere y Springfield.
“El modelo se instaló en zonas donde se encontraba el escarabajo y ahora es un modelo de éxito en todo el estado”, dice Ken Gooch, director del programa Forest Health Program, del DCR. “Hemos plantado miles y miles de árboles”.
Enfrentar los desafíos
La norma de zonificación en la ciudad de Worcester exige que se planten árboles alrededor del perímetro de un estacionamiento junto a una calle, parque o propiedad residencial que atienda a más de tres moradas residenciales. Además, se exige plantar árboles en el interior en terrenos con más de 16 lugares de estacionamiento, y la Política Completa de Calles del estado, promulgada en marzo de 2018, destaca los árboles en particular como parte importante de la vía pública, dice Stephen Rolle, director asistente de desarrollo de la ciudad.
Pero algunos barrios están menos dispuestos a tener árboles: los servicios, el cableado y las aceras en calles estrechas compiten por el espacio. Sencillamente, en ciudades urbanizadas hay menos lugar para plantar árboles, en especial los que dan mucha sombra y ofrecen más beneficios ambientales. Los jardines pluviales y de biofiltración urbanos a veces deben competir por el espacio con servicios y estacionamientos.
“En el centro, hay espacios asfaltados valiosos, y la gente no está segura de desprenderse de ese estacionamiento para colocar jardines de biofiltración o árboles en la calle”, dice Berard, de Green Infrastructure Coalition.
Rolle destaca otro desafío: el desarrollo de baja intensidad a veces se percibe como más caro, debido a los costos de instalación o los requisitos de mantenimiento. Pero “hay bastante evidencia que sugiere que los beneficios de dichas mejoras en suma superan a los costos”, dice. “Puede ser más barato asfaltarlo, pero eso no significa que sea lo mejor”.
Parte del esfuerzo de Green Infrastructure Coalition es apoyar la financiación de un emprendimiento para agua pluvial con los costos de un servicio. Los dueños de propiedades aportan a esta financiación según la cantidad de superficie impermeable en su terreno, y los fondos se invierten en proyectos que incluyen infraestructura verde. Pero Berard reconoció que es difícil convencerlos. “Como solución de políticas, está bastante aceptado que es la mejor forma de financiar programas”, dice. “Pero políticamente, tiene mal sabor”.
Con vistas al futuro, se están armando más planes en ambas ciudades. Worcester está involucrada en un proceso de plan maestro en toda la ciudad que considerará adaptaciones al cambio climático. La ciudad también recibió un subsidio de U$ 100.000 en 2018 para preparar una evaluación de vulnerabilidad ante el cambio climático.
Además, el departamento de Agua y Cloacas está desarrollando un plan a largo plazo para priorizar inversiones en infraestructura de agua, aguas residuales y agua pluvial en los próximos 50 años. Así, tiene la oportunidad de aumentar la capacidad de absorber agua pluvial mediante infraestructura verde.
La ciudad de Providence, por su parte, ha estado actualizando su Plan de Atenuación de Peligros, con un enfoque principal en preparación para el clima, indica Bamberger. Dice que, con la mayor presión del cambio climático, anticiparse y sembrar las semillas de una ciudad más ecológica serán las claves para la vitalidad.
“Si solo hay un día para prepararse, hay [menos] opciones . . . Tal vez solo se puedan trabar las escotillas”, dice. “Pero tenemos un poco de tiempo para pensar estratégicamente cómo debemos responder a estos impactos. Integrar la naturaleza al diseño urbano y apoyar los sistemas naturales de los cuales dependemos es crucial para crear una ciudad resistente al clima”.

If the Colorado River Basin is a test case for how a massive watershed can prepare for scarcity in the years ahead, recent news has been encouraging.
Seven states, tribes, conservationists, and other stakeholders agreed to a Drought Contingency Plan, signed into law by President Trump last month, that spreads out cutbacks so that Lake Powell and Lake Mead don’t drop too low.
While the seven-year agreement confronted the nuts-and-bolts realities of keeping water flowing to forty million people and five million acres of farmland, the hard work to bring about a truly sustainable future is just beginning, participants agreed at the Lincoln Institute Journalists Forum this spring in Phoenix. The two-day event, attended by about 50 reporters and editors, was organized by the Babbitt Center for Land and Water Policy in partnership with Walton Family Foundation, Gates Family Foundation, and the Arizona State University Walter Cronkite School of Journalism and Mass Communication.
“We’ve made enormous progress. We are learning to talk to each other,” said former Arizona Governor and U.S. Interior Secretary Bruce Babbitt (video). Now, he said, “We need to talk to each other about how we’re using water . . . how water gets used on the land.”
That conversation—both among and within Colorado River Basin states, with all stakeholders at the table—will help determine the best mix of future policies basin-wide, including conservation, efficiency, market pricing, and infrastructure. The problem, Babbitt said, is that the adversarial stance has dominated for so long—“waving the bloody shirt” as he put it, never giving in, never yielding a drop—it has blotted out these longer-term considerations.
“That’s where we’ve always been. How do we divvy up the river, who gets what share, how much, in what circumstances . . . and it’s nobody’s business about how it’s used,” he said. The sooner that changes, the better, he said, so the next crisis in the basin doesn’t dictate how this most precious resource is managed.
The Journalists Forum, a tradition at the Lincoln Institute going back nearly two decades, has focused on various themes including climate change, gentrification, infrastructure, and property rights, to name a few. This year’s issue was the Colorado River Basin and the integration of water management and land use—the mission of the Phoenix-based Babbitt Center, established two years ago. On social media, the hashtag was #WaterMeetsLand.
After hearing an overview of the history, hydrology, and the laws, treaties, and other agreements governing the use of Colorado River Basin water, the journalists considered how intensely and quickly climate change has complicated everything about the system. Despite this year’s relatively robust snowpack, warming trends will inexorably decrease supply, said Kathy Jacobs, director of the Center for Climate Adaptation Science and Solutions at the University of Arizona, and a leader in the National Climate Assessment initiative. Virtually all future decisions and actions must be based in the understanding of climate science, she said.
Climate change has also raised the stakes in the already challenging business of bringing together stakeholders, including those in agriculture, the growing constituency of urban areas, and environmentalists concerned about the integrity of ecosystems. The intensity of the crisis tends to make different groups feel defensive and wary, just at the moment when they should be open to new ideas, said Colorado rancher Paul Bruchez, who has worked to blend the interests of wildlife habitat, recreation, and irrigation needs for agriculture.
Similarly, indigenous peoples, overlooked or excluded from many previous agreements, bring a lot to the table. “Tribes have lived for hundreds of years in some kind of balance,” said Daryl Vigil, water administrator for the Jicarilla Apache Nation, and part of the Ten Tribes Partnership. “We want to show the world how we fit into this picture.”
The journalists also heard from Stephen R. Lewis, governor of the Gila River Indian Community; Terry Fulp, Lower Colorado Regional Director of the U.S. Bureau of Reclamation; and Roberto Salmón, Mexican commissioner of the Mexico-United States International Boundary and Water Commission (video). All emphasized the importance of keeping and building relationships, and basing decisions on solid evidence.
As the forum turned to exploring solutions, technology emerged as one of the more promising tools for making water infrastructure more efficient, improving conservation, facilitating desalination and storage, and revealing what’s happening to the water on the land through satellite imagery and data collection. A solid foundation of evidence can guide decision making in powerful ways, said George W. “Mac” McCarthy, president of the Lincoln Institute.
Data collection tells stories that confront the intense emotions pulsing through all issues of water and land, he said, citing the Chesapeake Bay Conservancy’s high-resolution mapping, which helped farmers pinpoint areas of runoff from fields. That knowledge allowed farmers and environmentalists to target riparian buffers where they were most needed, rather than requiring blanket solutions for such interventions throughout the properties. Two potential adversaries started working better together, aided by technology. “It changed the entire sociology,” McCarthy said.
Still, there was no universal agreement about the path forward. “We have to address the structural deficit,” said Pat Mulroy, senior fellow at the William S. Boyd School of Law at the University of Nevada, Las Vegas, and a veteran of water battles (video). That means augmenting the system with new sources, and entertaining more radical ideas, like the sea-to-sea pipeline to stabilize California’s Salton Sea and the provision of extra water through desalination. “We can’t get through the next seven years simply by taking away. You can manage the system all you want. It’s going to crash. . . . You can’t conserve your way out of it. Everything has to be on the table.”
Added Dave White, director of the Decision Center for a Desert City at Arizona State University: “There is simply no historical record that approximates what the future will be under the climate change scenario. . . . The mechanisms designed for the system thus far” can’t just be tweaked.
Yet all stakeholders should stay wary of “magical thinking” and a quest for a silver bullet, which can become a distraction, said Jennifer Pitt, Colorado River Program director for the Audubon Society. Others agreed that there is still plenty to gain by eliminating grass lawns, recycling water for use in toilets, or finding different ways to grow thirsty crops—and by scrupulously linking water management with land use, zoning for housing, and economic development. Many of those steps are being taken at the local level, seen in one presentation on policies and initiatives in the city of Westminster, Colorado.
Anne Castle, senior fellow at the Getches-Wilkinson Center for Natural Resources at the University of Colorado, Boulder, echoed the sentiments of several speakers by pointing out that the window for action will close soon. “We’ve only got a couple of years to do a lot of creative thinking and change our paradigm.”
Many agreed that the management of water resources “needs a lot of journalistic attention,” as Bruce Babbitt put it. Reporters and editors shared how they have engaged readers on the topic by telling stories that go beyond horse-race coverage of incremental political wins.
Ted Kowalski, senior program officer for the Walton Family Foundation’s Colorado River initiative, announced the establishment of The Water Desk, an independent news organization dedicated to coverage of Western water issues, to be led by Mitch Tobin at the University of Colorado.
In a session titled “Practicing the Craft,” Elizabeth Hightower Allen, features editor at Outside magazine, shared examples of content that engages readers by building on human drama. The challenge is to draw in the “concerned middle” between those who are “freaked out” and those who deny there is a crisis unfolding, suggested Cynthia Barnett, environmental journalist in residence at the University of Florida College of Journalism and Communications.
Paolo Bacigalupi, author of The Water Knife, fielded questions about his disturbing narrative of a dystopian future of chronic water shortages. The dark and action-packed novel was certainly one way to draw attention to water issues. But, he added, “I’d love to be proven wrong,” he said.
The journalists agreed that while specialized outlets like Circle of Blue, Aspen Journalism, and ProPublica have been putting water issues front and center, there is no substitute for thoughtful coverage by major metropolitan newspapers, which can have greater influence on elected officials and policy makers. One important journalistic obligation emerged: holding all parties accountable for following through with commitments.
Coverage flowing from the 2019 Journalists Forum included dispatches by Josh Stephens at California Planning & Development Report Jason Blevins at The Colorado Sun Ry Rivard at the Voice of San Diego and Tom Yulsman at Discover magazine. James Brasuell, managing editor at Planetizen, has also been aggregating stories about water and land use here.
Slide show presentations and videos of portions of the Journalists Forum are available on the Lincoln Institute website.

Though frequently seen as an urban liability, brownfields can be an asset. The cost to remediate these formerly developed properties is often high, but they present valuable opportunities for revitalization and redevelopment. According to the EPA, waterfront brownfields “can play an important role in bolstering local resilience to increased flooding, storm surge, or temperatures from a changing climate.” In Providence, brownfields are a top priority in the ongoing effort to revitalize river corridors and riverfront areas.

As rain sheeted across the 150,000-square-foot roof of a transit facility in one of the most flood-prone neighborhoods in Worcester, Massachusetts, things looked ominous. But instead of posing a threat, that stormwater slithered into a jumble of purple coneflower, Joe Pye weed, Russian sage, and other flood- and drought-tolerant plants growing between the complex and nearby Quinsigamond Avenue.
The transit facility, built on a remediated brownfield, represents a $90 million investment for this small city. Green infrastructure elements like that rain-absorbing bioswale were considered a must, according to William Lehtola, chair of the Worcester Regional Transit Authority Advisory Board: “We want to provide the best possible environment for the city and our customers and employees,” he said. “Not just in our buses, but in our facilities too.”
As smaller legacy cities like Worcester and nearby Providence, Rhode Island, continue the grueling work of rebounding from the severe economic and population losses suffered since their manufacturing heydays, the green approach is gaining traction. Despite challenges ranging from financial constraints to deteriorating infrastructure, many legacy cities have realized that investing in—and, in some cases, mandating—green infrastructure yields multiple benefits. Projects such as rain gardens, bioswales, urban farming, and tree planting, whether introduced on a small scale or implemented citywide, are an effective way to revitalize public spaces, manage stormwater, improve public health, and deal with the impacts of climate change, from increased heat to floods.
“Green infrastructure can address multiple challenges, and provide amenities as well,” says Professor Robert Ryan, chair of the Landscape Architecture and Regional Planning Department at the University of Massachusetts, Amherst. Ryan has led courses on greening legacy cities including Worcester. “Cities like Worcester and Providence are the ideal place for this approach.”
Cultivating this shift isn’t always simple. While new environmental codes, regulations, and awareness have increased the frequency of green infrastructure projects, they still often coexist with structures and streetscapes from an earlier era, when nearby waterways were de facto sewers, and pavement was the go-to choice for urban improvements.
As legacy cities across the country implement green infrastructure projects and strategies, they are coping with an important reality: They cannot just create themselves anew. They can, however, adapt and evolve.
A New Lease on Life in New England
Located in a hilly area of central Massachusetts, Worcester is home to an estimated 185,000 people. Its population peaked at 203,486 in 1950 and dipped to about 161,000 by 1980.
Worcester was always the economic hub for surrounding Worcester County. But it earned the moniker “Heart of the Commonwealth” thanks to connections with Boston (via railroad in 1835) and with Providence (via the Blackstone Canal in 1828 and the Providence & Worcester Railroad in the late 1840s), which made it an increasingly important industrial and transportation hub. It became known for its machine tools, wire products, and power looms.
Providence, perched on the banks of the Providence River at the head of Narragansett Bay, has followed a similar path, albeit in a different setting. The coastal city is home to approximately 180,000 people. That’s up from a twentieth-century low of 156,000 in 1980, but far smaller than the peak of more than 253,000 in 1940. The state capital, Providence became a manufacturing powerhouse after the Revolutionary War, with factories churning out goods such as jewelry, textiles, silverware, and machinery, and shipping them from its port. At one point, it was one of the wealthiest cities in the country.
In both cities, the industrial activity and the population eventually declined and, coupled with suburbanization, left hollowed-out sections of formerly vibrant urban cores (see Figure 1).
But, as is the case with many legacy cities, people have slowly rediscovered the assets these communities offer. As Alan Mallach and Lavea Brachman explain in the Lincoln Institute report Regenerating America’s Legacy Cities, these assets include downtown employment bases, stable neighborhoods, multimodal transportation networks, colleges and universities, local businesses, historic buildings and areas, and facilities for arts, culture, and entertainment (Mallach 2013).
Providence, for instance, is home to Brown University, the Rhode Island School of Design, the University of Rhode Island, and Johnson & Wales. Worcester is home to more than a dozen institutions of higher learning including Clark University, College of the Holy Cross, Worcester Polytechnic Institute, and University of Massachusetts Medical School. Both cities have major hospitals and performance venues. And both cities have revitalized their downtowns with signature projects.
Providence successfully rebranded itself as an arts and cultural hub beginning in the 1990s. In a massive green infrastructure effort, the city unearthed the Providence River, formed by the confluence of the Woonasquatucket and Moshassuck rivers, which had long been buried under parking lots and railroad tracks, and lined the banks with parks and pedestrian-only walkways. (“The river has to be an integral part of the city,” said then-Mayor Vincent “Buddy” Cianci Jr. “Don’t cover it, don’t block it, don’t pollute it. Celebrate it and use it.”) The massive effort changed the character of the downtown, which soon began to draw new development projects—including ambitious renovations of vacant mill buildings—as well as new residents and businesses.
Worcester is replacing its failing downtown mall with the $565 million, mixed-use CitySquare redevelopment, reconnecting the central business district with other burgeoning parts of the city such as Washington Square—the home of the renovated Union Station—the restaurants of Shrewsbury Street, and the hip Canal District. In fact, Worcester was deemed “high performing” among cities of its size in the Lincoln Institute report Revitalizing America’s Smaller Legacy Cities (Hollingsworth 2017). Factors cited in this designation included its proximity to Boston and easy access via commuter rail; leaders who have the energy and skills to revitalize the city; and the CitySquare project. Providence was not included in either Lincoln Institute report, but its revitalization efforts have been heralded by organizations from the American Planning Association to The New York Times.
Although this momentum is promising, climate change complicates everything. In the Northeast, climate change is associated with more frequent extreme weather events including heavy rainfall and flooding, droughts, warmer air and water temperatures, changing circulation patterns in the ocean (and related impacts on weather and fisheries), and sea-level rise. Providence is positioned to see flooding and damage from more intense Nor’easters and hurricanes that slam into its shores; a climate report prepared in Worcester nods to predicted impacts including “increased temperatures, more extreme heat days, and changing precipitation patterns.”
“Some degree of climate change is inevitable—there’s literally nothing we can do about it now,” said Edward R. Carr, professor of international development, community, and environment at Clark University in Worcester. “The question is, how much can we deal with it, and what is that going to look like.”
Where Revitalization and Preparedness Meet
“The most fundamental rationale for thinking about green infrastructure is to come up with uses for a massive accumulation of vacant lots, so it will not be a blight and hopefully will [have] a positive effect on the neighborhood,” said Alan Mallach. “Historically, a lot of people had the theory that a vacant lot was worthless unless you built something on it. But that’s changing. There are a number of ways you can take a vacant lot and make it valuable to the community, whether for recreation, to produce fresh food, address sewer overflow. There are ways to address vacant lots that don’t require building new housing or office buildings.”
As legacy cities assess such land use opportunities, they sometimes lack the political or economic power to engineer effective solutions. But there’s one area in which legacy cities have an advantage: They are seeking to reinvent themselves as healthier, more appealing places to live, so they are often more willing to embrace novel and creative projects. This will be helpful in the era of climate change, says Amy Cotter, associate director of Urban Programs at the Lincoln Institute.
“If you think about ways we could prepare legacy cities to play key roles in a future where climate change is affecting large population centers, green infrastructure could be both a revitalization strategy and a climate preparedness strategy,” said Cotter. “It can also help places revitalize and deal with what otherwise would be the blight of vacant property.”
Larger legacy cities across the country have embraced a suite of options with these goals in mind. In Detroit, a comprehensive green infrastructure effort has led to a citywide sprouting of green roofs, rain gardens, and a “green alley” program in which native plants and permeable pavers replace urban debris and concrete in previously neglected alleyways. In Cleveland, the regional sewer district manages a green infrastructure grants program, and ambitious plans are coming together for a park that will occupy 20 acres of formerly industrial waterfront along the Cuyahoga River. Philadelphia is investing approximately $2.4 billion in public funds over 25 years to do everything from provide rain barrels to create urban wetlands in order to reduce combined sewer overflow.
Smaller legacy cities with populations under 200,000 don’t always garner headlines, or have the resources and capacity to undertake such large projects, but many are making similar efforts. Worcester and Providence demonstrate how smaller legacy cities—one coastal, one inland—are relying on green infrastructure to help them rebound from the challenges of the last century and prepare for the uncertainties of the decades ahead.
“Not only does green infrastructure act as an environmentally friendly alternative to traditional stormwater systems, it can help protect us from climate impacts like urban heat island and coastal erosion, and be used in streetscape design to make our roads safer for cyclists and pedestrians,” said Leah Bamberger, the city of Providence’s director of sustainability. “Providence is a forward-thinking city, and green infrastructure is an opportunity to invest in green jobs while building a healthier, thriving community.”
Finding Stormwater Solutions
In the last 80 years, Rhode Island and southern New England have experienced a doubling of flood frequency and an increase in the magnitude of flood events, according to the report Resilient Rhody: An Actionable Vision for Addressing the Impacts of Climate Change in Rhode Island (State of Rhode Island 2018).
Unfortunately, the region’s infrastructure isn’t up to the challenge.
“Much of the state’s stormwater infrastructure was built at least 75 years ago and was designed for less intense storms,” the Resilient Rhody report says. “Climate change further challenges the capacity and performance of these drainage systems.”
Carr says the same is true of the Worcester area, noting that the “infrastructure here is simply not built to handle . . . what is becoming normal.”
“Climate adaptation is very specific to place,” says Ryan of the University of Massachusetts, who coedited Planning for Climate Change: A Reader in Green Infrastructure and Sustainable Design for Resilient Cities, published by Routledge. “For these particular cities, and for any legacy city, the question is how do they accommodate the extra water that comes with sea-level rise and increased precipitation.” Pointing out that neighborhood development patterns have tended to stem from the historic location of worker housing near riverside mills and factories, Ryan says flooding raises equity issues too: “How do cities protect the vulnerable populations in those low-lying areas?”
With this array of concerns in mind, public and private entities are taking action. The Green Infrastructure Coalition in Rhode Island—made up of more than 40 nonprofit organizations, city planners, architects, elected officials, and others—works to promote green infrastructure projects as one way to reduce stormwater problems such as flooding and pollution.
The coalition hires local crews to install green infrastructure projects, such as a bioswale in a local park, a green roof, or a rain garden, and trains public works employees and other involved parties on maintenance. “It’s small projects right now, but it seems that the need and appetite for this is growing,” said John Berard, Rhode Island state director of Clean Water Action, which acts as the project organizer for the coalition. “We’re seeing it get more and more prevalent as storms get worse, and cities are realizing that stormwater is a really important piece for managing a city effectively.”
Meanwhile, the city of Worcester has put policies in place that help ensure sound stormwater management. The city regulates runoff near wetlands and catch basins that drain directly to wetlands or water resource areas.
Additionally, all development and redevelopment must have no net increase in runoff rates, often leading to on-site stormwater management systems for large developments.
The city also aggressively protects land within its watershed to improve the quality of its drinking water and offset some of the land lost to development, according to Phil Guerin, director of water and sewer operations for the city.
But Guerin noted that the built-up nature of Worcester, as well as the geology of the city, makes it difficult to decrease the amount of impervious surfaces. “There are lots of areas with shallow bedrock, a shallow water table, and it’s a pretty built-up city,” Guerin said.
Combating the Urban Heat Island Effect
A few years ago, scientists from NASA set out to understand the difference between surface temperatures in the cities of the Northeast and surrounding rural areas. Their research revealed that surface temperatures in the cities were an average of 13 to 16 degrees hotter than surrounding areas over a three-year period. In Providence, surface temperatures are about 21.9 degrees warmer than the surrounding countryside (NASA 2010). The compact size of Providence contributed to this heat island effect, which is caused by buildings retaining heat and by urban infrastructure such as pavement.
When it comes to combating the heat island effect, the answer is clear, says Carr of Clark University: “Trees, trees, trees. There are tons of studies that urban tree cover makes a tremendous difference in lowering temperatures, improving air quality, and—to some extent—helping with flooding.”
According to the U.S. Department of Agriculture, a healthy, 100-foot-tall tree can take 11,000 gallons of water from the soil and release it into the air again in a single growing season.
In 1907, the city of Providence recorded approximately 50,000 street trees, according to the local nonprofit Providence Neighborhood Planting Program (PNPP). The city currently has just half that amount—approximately 25,500 street trees—according to the sustainability dashboard on the City of Providence Sustainability website. A citywide tree inventory is underway.
In its Trees 2020 plan, Providence aims to increase the tree canopy 30 percent by 2020 and plant 200 trees annually. The city has partnered with PNPP, offering grants for tree planting and providing the curb cuts, tree pit, and trees for free. In addition, PNPP and the city offer the Providence Citizen Foresters program, which provides technical training focused on the care of young urban trees. PNPP has cofunded the planting of more than 13,000 street trees with more than 620 neighborhood groups since 1989.
“If people are engaged and want the tree, they’re more likely to care for it and nurture it,” said Bamberger. “You can plant the trees all day long, but if there’s no one there to care for them and nurture them, they’re not going to last long.”
Ryan echoes that sentiment, drawing from research he has been involved with on community gardens in Boston and Providence. “You often have outside groups come to cities and neighborhoods saying how wonderful green infrastructure is, but unless a community wants it— and wants to maintain it—it doesn’t sustain itself so well over time,” he says. “Green infrastructure needs to be both top-down and bottom-up. A bottom-up approach seems to have longer-term impact in terms of stewardship and making projects work.”
In Worcester, a robust tree-planting effort grew into a statewide success story. In 2008, the discovery of the invasive Asian longhorned beetle (ALB) in Worcester led to a massive eradication effort that would fell 35,000 trees in a 110-square-mile quarantine area in the city and adjacent towns. (Four years later, students at Clark University began studying the impact of the tree loss, noting that the heat island effect had increased in a neighborhood that had lost its trees, as did heating and air conditioning bills.)
An ambitious replanting effort known as the Worcester Tree Initiative kicked off in 2009, with the city and state Department of Conservation and Recreation (DCR) partnering to plant 30,000 trees in just five years in private yards, in parks, and along streets. The program recruits neighborhood tree stewards to care for and monitor the trees, and runs a Young Adult Forester program in the summer for at-risk youth.
The partnership has been so successful that the DCR has expanded it to other cities in Massachusetts through its Greening the Gateway Cities Initiative. This program is concentrated in areas within cities with lower tree canopy, older housing, and a larger renter population. DCR works with local nonprofits and hires local crews to plant trees for environmental benefits and energy efficiency. The program is currently active in Brockton, Chelsea, Chicopee, Fall River, Haverhill, Holyoke, Lawrence, Leominster, Lynn, New Bedford, Pittsfield, Quincy, Revere, and Springfield.
“The model was established in ALB areas and is now a successful model across the state,” said Ken Gooch, director of the DCR’s Forest Health Program. “We’ve planted thousands and thousands of trees.”
Facing Challenges
The city of Worcester’s zoning ordinance requires that trees be planted around the perimeter of parking areas abutting a street, park, or residential property and serving more than three residential dwellings. Additionally, interior tree plantings are required in surface lots with more than 16 spaces and the state’s Complete Streets Policy, enacted in March 2018, specifically calls out trees as an important part of the public street, noted Stephen Rolle, assistant chief development officer for the city.
But some neighborhoods are less amenable to trees, as utilities, power lines, and sidewalks on narrow streets compete for space. There are simply fewer places to plant trees in built-up cities, particularly the large shade trees providing the most environmental benefits. Urban rain gardens or bioswales often have to compete for space with utilities and parking areas too.
“There is valuable paved space downtown, and people are hesitant to let that parking space go to put in bioswales or street trees,” said Berard of the Green Infrastructure Coalition.
Rolle notes another challenge: low-intensity development is sometimes perceived as more expensive, because of installation costs or maintenance requirements. But “there’s quite a bit of evidence suggesting that the benefits of such improvements overall outweigh the costs,” he says. “It can be cheaper to pave it, but that doesn’t make it the right choice.”
Part of the Green Infrastructure Coalition’s advocacy includes support for a stormwater enterprise fund with a utility fee. Property owners pay into this fund based on the amount of impervious surface on their land, with the funds dedicated to projects including green infrastructure. But Berard admitted it’s a tough sell. “As a policy solution, it’s pretty much accepted to be the best way to fund programs,” he said. “But it’s politically unpalatable.”
As the two cities look ahead, more plans are taking shape. Worcester is engaged in a citywide master plan process that will consider adaptations to climate change. The city also received a $100,000 grant in 2018 to prepare a citywide climate change vulnerability assessment.
The Water and Sewer department is also developing a long-term plan to prioritize investments in water, wastewater, and stormwater infrastructure over the next 50 years, giving the department an opportunity to look at increasing stormwater capability through green infrastructure.
Meanwhile, the city of Providence has been updating its Hazard Mitigation Plan, with a major focus on climate preparedness, said Bamberger. As climate change bears down, she says, thinking ahead and planting the seeds for a greener city will be the key to vitality.
“If you only have a day to prepare, you have [fewer] options . . . You may only get to batten down the hatches,” Bamberger said. “We do have some time to think strategically as to how we need to respond to these impacts. Integrating nature into urban design and supporting the natural systems we depend on is critical to creating a climate-resilient city.”
