A new online guide launched today by the American Society of Landscape Architects (ASLA) explains how communities can better protect themselves from natural disasters through resilient landscape planning and design.
According to the guide, the goal of resilient landscape planning and design is to retrofit communities to recover more quickly from extreme events, now and in the future. In an era when disasters can cause traditional, built systems to fail, adaptive, multilayered systems can maintain their vital functions and are often the more cost-effective and practical solutions.
The guide includes hundreds of case studies and resources demonstrating multi-benefit systems as well as small-scale solutions. It also explains landscape architects’ role in the planning and design teams helping to make communities more resilient.
Resilient design involves working with nature—instead of in opposition to it. It provides value to communities, including:
Risk reduction: As events become more frequent and intense due to climate change, communities must adapt and redevelop to reduce potential risks and improve ecological and human health. It’s also time to stop putting communities and infrastructure in high-risk places. And communities must reduce sprawl, which further exacerbates the risks.
Scalability and Diversity: Resilient landscape planning and design offers a multi-layered system of protection, with diverse, scalable elements, any one of which can fail safely in the event of a catastrophe.
Multiple Co-Benefits: Resilient landscape design solutions offers multiple benefits at once. For example, designed coastal buffers can also provide wildlife habitat and recreation opportunities; urban forests made up of diverse species clean the air while reducing the urban heat island effect; and green infrastructure designed to control flooding also provides needed community space and creates jobs.
Regeneration: Disruptive natural events that are now occurring more frequently worldwide harm people and property. Resilient design helps communities come back stronger after these events. Long-term resilience is about continuously bouncing back and regenerating. It’s about learning how to cope with the ever-changing “new normal.”
In an era when disasters can cause traditional, built systems to fail, adaptive, multi-layered systems can maintain their vital functions and are often more cost-effective and practical solutions. In an age of rising waters and temperatures and diminishing budgets, the best defenses are adaptive, like nature.
The guide to resilient design has been strengthened through the expert guidance of Alexander Felson, ASLA, assistant professor, School of Forestry & Environmental Studies and Yale School of Architecture; Kristina Hill, Affiliate ASLA, associate professor of landscape architecture and environmental planning and urban design, University of California at Berkeley; Nina-Marie Lister, Hon. ASLA, graduate program director and associate professor, Ryerson University School of Urban and Regional Planning; Nate Wooten, Associate ASLA, landscape designer, OLIN; and Kongjian Yu, FASLA, founder and dean, Peking University College of Architecture and Landscape and Turenscape.
In the face of rapidly-declining honeybee populations, farms across the country are under threat. In California, officials are now pioneering new methods to boost the health of the honeybees and butterflies, according to a recent Congressional hearing in Washington, D.C. To reiterate the importance of these efforts, Congressman Jeff Denham, who is also an almond farmer, said at the briefing: “making sure we have healthy pollinators is critical to a state like California.”
There to discuss these pioneering methods was Keith Robinson, ASLA, principal of the landscape architecture program at the California Department of Transportation (Caltrans). The purview of Robinson and the 240 landscape architects he leads is roadsides. Their primary job is to control erosion. But Robinson and his team have seized on that mandate to boost the health of pollinators along California’s 250,000 acres of highway roadside.
Robinson said it all starts with the soil. “We are prioritizing the improvement of soil quality on every single project. We want to make sure that soil sustains native plants and creates favorable conditions that encourage pollinator plants to not only to grow but thrive.”
Robinson’s team began this effort by performing studies on the optimal amount of compost that can be included in the soil. Compost “gets things moving along, and then the natural process takes over.” The right amount of compost allows native species to out-compete non-natives, foregoing the need for many herbicides that might negatively impact pollinators. Robinson’s team realized they could use Caltrans’ often-idle snow blowers to spread compost.
Another innovative step taken by Robinson’s team was the development of native grass sod, or pre-packaged grass carpet. “With native grass, the thinking was you can’t cut the roots and expect the plant to grow. But we’ve proved that it works.” Native grasses not only help erosion control, they encourage pollinators. “If you compare this solution to what we used to do, which was put straw down on top of compacted soil and hope for the best, you can see we’re moving down a path towards natural solutions,” Robinson said.
In addition to these steps, Caltrans ramped up planting pollinator-friendly plant species along highways. TransPLANT, an online tool, helps landscape architects choose sustainable, pollinator-friendly plants for their own projects.
Whether these effort can benefit pollinators fast enough is unknown. Robinson noted no studies have been performed on pollinator habitat health in state highway rights-of-way. And a recent study done by the Xerces Society for Invertebrate Conservation found that monarch butterfly populations in California have declined 74 percent in the past two decades.
Another speaker, Eric Silva, American Honey Producers Association, expressed resignation that reversing the trend on bee populations was a losing battle. “We’re losing half the bees over the course of the year.” The environmental culprits are relatively well-known: pesticides and chemicals, habitat loss, and pests.
Robinson offered hope for the future. His team has developed an online roadside management toolbox that helps other transportation departments learn from Caltrans’ methods. The site has tens of thousands of visitors in the U.S., but has also gotten healthy traffic from countries such as India and Canada.
And regarding the future of roadside planting, Robinson envisions hyper-local roadside ecosystems that include native as well as non-native, well-adapted species. “The pollinator and native plant advocates have voiced their appreciation for our efforts,” Robinson added. “I don’t think the public is as aware of what we are doing yet.”
The panel, which was led by Adam Greenspan, ASLA, a member of the LAF board of directors, essentially worried that the importance of “physical design, which engages culture and nature,” may be lost in the total quest for sustainability and restoring ecosystems. Their response was designed landscapes must be beautiful if we expect communities to love them and take care of them far into the future.
Claude Cormier, ASLA, principal of Claude Cormier + Associates, said aesthetics has always played a central role in landscape architecture. Frederick Law Olmsted was “focused on nature as an aesthetic experience.” For Mikyoung Kim, FASLA, Mikyoung Kim Design, it’s less about aesthetics, a term she dislikes, and more about the “process of creativity, which is methodical and conscious, and about tapping intuition, which occurs on a subconscious level.” But she cautioned that if landscape architects were “too creative, they risk missing the pressing global issues.”
In the context of the overall summit, this seemed like a shocking statement: “We can’t save the world, but we can address some major issues through design in contemporary ways,” argued Chris Reed, FASLA, founder of Stoss. “Design can move people’s hearts to create action.” Ken Smith, FASLA, principal of Ken Smith Workshop, largely concurred, arguing that “aesthetics matter. The qualitative aspects — the spaces, programs, forms — provide meaning to humans. Landscapes can delight, confound, confuse, excite us.” He pointed to the art world, where the “new is often ugly,” arguing that perhaps landscape architects also need to be pushing the boundaries on concepts of beauty. Meanwhile, Maria Goula, associate professor at Cornell University, asked: “do we need new aesthetics or perhaps multiple aesthetics?”
Ecology: Make Ecological Design Mainstream
“People will look at us and this time and say we just didn’t get it,” said Kristina Hill, Affiliate ASLA, professor at University of California, Berkeley, referring to the many dangers facing our ecosystems and planet. Hill, who moderated the ecology panel, relayed how San Francisco’s city government momentarily fell into crisis when a senior official at the National Oceanic and Atmospheric Administration (NOAA) stated they expected a 6-9 feet sea level rise by 2050. While it was just one official’s personal opinion, San Francisco’s panicked response showed that “stronger sense of urgency is needed” in the push to adapt our ecosystems to the coming environmental changes. “Unprecedented instability is coming. The role of landscape architects is to think out the options and try not to panic.”
Ellen Neises, ASLA, an adjunct professor at University of Pennsylvania, said in this age of crisis, we need to move away from “sustainability propaganda in which ‘optimism sells.'” Instead, “designers need to provoke more.” Jose Alminana, FASLA, a principal at Andropogon Associates and major force behind the Sustainable Sites Initiative (SITES), rued that ecology is “still not mainstream in our profession.” He called for landscape architecture educators to “embed scientific rigor in the educational process,” and landscape architects to do the same in their design process. “Beauty and performance aren’t mutually exclusive. All forms of life matter.”
Brett Milligan, ASLA, University of California, Davis, argued that “if we do things to the landscape, they sometimes respond in some ways we dislike. We need a new, relational way to interact with the landscape.” Julie Bargmann, founding principal, D.I.R.T. Studio, urged caution against becoming too all-knowing about nature, arguing that “ecological models are slippery.” And Antje Stokman, International ASLA, professor at the University of Stuttgart, called for creating methods to encourage “direct community engagement with the environment,” particularly in environments characterized by heavy migration among both human and other species.
Society: Diversify and Co-design with Communities
Deb Guenther, FASLA, partner at Mithun, led a discussion that focused on the twinned goals of increasing diversity in the landscape architecture profession and better reaching under-served communities. Diane Jones Allen, ASLA, principal at DesignJones, pointed to ASLA’s ongoing efforts to increase diversity through its annual diversity summit, which brings together emerging African American and Latino landscape architects, but also called it like she saw it: “if we truly want diversity, we need to focus less on statistics and instead recognize and praise diversity and lift it up.” She pointed to the range of African American landscape architects doing important work, often under the radar. Jeffrey Hou, ASLA, professor at University of Washington, added that “landscape architects need to diversify their ranks or risk becoming a profession of colonialists,” coming in as white experts into communities of color.
“Landscape architecture can diversify in the next decade or two,” because just look at the huge gains that have been made to bring in more women over the past 50 years, argued Anne Whiston Spirn, FASLA, a professor at MIT. She explained her multiple decades of experience helping African American communities in Philadelphia unearth their own landscapes, explaining how “long-term commitments are needed to build trust.” She wondered whether landscape architecture programs, with their semester-long field projects, can truly engage and learn from communities in which they dip for a short time. Jones Allen concurred, arguing that “we have to be careful how we get students into these communities, but it’s important to get them out of their comfort zone of the studio and face real people with real issues. Students are learning.” Allison Hirsch, ASLA, an assistant professor at the University of Southern California, was less positive, arguing that “landscape architects tend to avoid issues of inclusion; there are few community-oriented design practices.”
For Spirn and others, the solution is more equitable design processes rooted in co-design and a participatory process with stakeholders. The goal should be capacity building among communities. “Make the design process transparent, not opaque,” argued Spirn.
Innovation: Move Beyond the Discipline
Adrian McGregor, Internatonal ASLA, a founder of McGregor Coxall in Australia, envisions a “new economy that trades in carbon, which will raise underlying values of ecosystems,” eventually resulting in a new “NASDAQ for the environment.” The growing importance of sequestering carbon in the environment will “put landscape architects at the table.”
Andrea Hansen, founder of Fluxscape, wants landscape architects to “move beyond the discipline, embrace holistic thinking,” and embrace open data. But she added that increasing innovation doesn’t necessarily mean “increasing complexity; we must keep it simple when we communicate to expand our reach.” To realize this reach beyond the discipline, Marcel Wilson, ASLA, founder of Bionic, called for more experimentation and risks, even if they result in failures. “We must incentivize innovation; landscape architects have become too reactive.”
Liat Margolis, ASLA, director of the Green Roof Innovation Testing Laboratory (GRIT Lab), University of Toronto, appears to be doing what Wilson called and Hansen have called for, as she works to create the next generation of green roof technologies. “We need to discover different material composites, bridge performance gaps, and exceed current green design benchmarks through experimental design.”
And Karen M’Closley, ASLA, an associate professor at the University of Pennsylvania, similarly called for a “new set of sustainable design indicators, set-up pre-occupancy and post-occupancy surveys, and capture results in real-time.” Margolis finally asked: “where is the landscape architecture field’s think tank?”
The second day of the Landscape Architecture Foundation‘s New Landscape Declaration: Summit on Landscape Architecture and the Future offered critical responses to the 23 declarations delivered on the first day of the event and looked ahead to the next 50 years. Afternoon sessions were divided into five panels, each representing a different aspect of landscape architecture: academic practice, private practice, public practice, capacity building organizations, and emerging voices. Each panelist gave a short talk before engaging in a group discussion, addressing audience-sourced questions, and offering perspectives on what needs to be achieved over the next 50 years:
Academic practice: Maintain the value of the “long view”
“Academics combine teaching, scholarship, and service” while “taking the long view: looking back, then to now, and forward,” argued University of Illinois professor Elen Deming, ASLA, moderator of the first panel. The panel largely resisted responding to the more-urgent cries for action from the first days’ declarations, with Jacky Bowring, professor at Lincoln University, cautioning, “there is power and danger in the language we use.”
The academicians saw the future of landscape as both cultural art and applied science. While Anu Mathur, ASLA, professor at the University of Pennsylvania, championed “design as a field of inquiry” in which “design tools and techniques are our academic science,” Susan Herrington, ASLA, professor at the University of British Columbia, reminded the largely-professional audience that design schools “do not train scientists,” citing long hours in the studio. Yet a question from the audience concerning the rising costs of education revealed that a lack of scientific rigor in landscape architectural research limits access to external funding that could help lower escalating costs.
Julia Czerniak, ASLA, professor at Syracuse University, spoke to the power of design writing and criticism in spreading ideas. Other panelists noted the academy’s global reach comes from the increasingly international students it recruits and where schools build partnerships.
Anita Berrizbeitia, ASLA, professor and chair of landscape architecture at Harvard University, delivered four points the panel saw as critical to the future of academic practice: 1) commit to frameworks of learning, 2) avoid binaries and ideologies, 3) encourage student thinking and action, 4) increase diversity and range of students.
Private practice: Lead through collaboration and deep expertise
The private practice panel was moderated by Laura Solano, ASLA, principal at Michael Van Valkenburgh Associates (MVVA), who emphasized that practitioners deal with the challenges of not only serving clients and achieving design excellence, but most also “run profitable businesses, all without harming the earth.” In their contribution toward a new declaration, the practice panel called for firms to become increasingly adaptable and gain deeper expertise.
Joe Brown, FASLA, consulting advisor at AECOM, insisted that “practices must respond to students’ ambitious ideals.” He later added that larger firms can act as teaching institutions as well, helping students achieve their new ideas. Thomas Balsey, FASLA, founder of Thomas Balsley Associates, agreed that in private practice, “a commitment to growth and evolution” can come from being open to what students bring. Through internships and the induction of recent graduates, Balsley offered ”student-led seminars” as a bridge between the ideas of the academy and the constraints of contemporary practice. Kathryn Gustafson, FASLA, founding principal at Gustafson Guthrie Nichol, claimed “education in firms will be the biggest draw in future private practice.”
The panel addressed the importance of having both deep expertise and leadership skills as landscape architects manage complex, collaborative projects. Mark Johnson, FASLA, co-founder of Civitas, noted that being a leader isn’t just about being a “good generalist, but also an expert.” Balsley, who saw collaboration as the key for smaller firms to get big commissions, elaborated: “you need preparation and dedication to being an expert to be capable of collaborating.” Or as Gustafson put it, “to let landscape lead, you have to be the smartest person in the room;” but also be pro-active: “know your experts and demand what you need from them.”
Adding a more critical voice to the private practice panel was Keith Bowers, FASLA, founder and principal at BioHabitats. Noting he is often on the other side of these collaborations, providing ecological design services, Bowers re-asserted the importance of private landscape practices to lead by “turning around political and financial institutions.” He emphasized the importance of sticking to your environmental values and having “conviction, spirit, and humility in everything you do.”
Public practice: Change policy to achieve impact
Mia Lehrer, FASLA, president of Mia Lehrer + Associates, led the public practice panel, which advocated for their important role in “defending and expanding” landscape’s role, all the while “creating places of experience that stick with people throughout their lifetime.” Acknowledging the stigma of bureaucracy, Nette Compton, ASLA, senior director of ParkCentral and City Park Development at the Trust for Public Land, said to “young professionals: you can get a lot done at a young age;” her own rise in the New York City parks department being but one example.
Joking that landscape architects are a “shade-loving species,” Mark Focht, FASLA, former ASLA president and senior official in Philadelphia’s parks department, joined others on the panel in suggesting landscape architects must “push themselves out there” into positions of power and “demand design excellence for under-served communities.” This point was affirmed by Deborah Marton, executive director of New York Restoration Project, who noted that “private dollars rarely go into low-income places.”
Going one step further was Christian Gabriel, ASLA, national design director of landscape architecture for U.S. General Services Administration, who encouraged landscape architects to be “infiltrators and insurgents,” using policy as a mechanism to deliver action. Citing his involvement in the Obama administration’s efforts to restore pollinators to health, Gabriel thinks re-conceptualizing policy through ecosystem services “is where our greatest future and capacity lies.”
Picking up on the Beth Meyer’s keynote speech and Martha Schwartz’s declaration from the first day of the LAF Summit, Edward Garza, CEO Zane Garway and former mayor of San Antonio, challenged landscape architects to “embrace the political world” and even to run for mayor.
Capacity organizations: Design a path to increased diversity
As demonstrated by the summit itself, capacity organizations like LAF play a crucial role in forging the future of landscape architecture. Having heard all the declarations and much of the audience and Q & A, the panel, which included representatives from the LAF, American Society of Landscape Architects (ASLA), International Federation of Landscape Architecture (IFLA), Public Architecture, and the Urban Land Institute (ULI), acknowledged how important diversity is to the future of the profession. Nancy Somerville, Hon. ASLA, executive vice president and CEO of ASLA, announced a multi-organizational effort entitled Mirroring the Nation, which is meant to attract and support more minorities to the profession, so that “our profession might better mirror the population it serves.”
The panel also called for landscape architects to have more impact on a global level. Leading the cause was Raquel Penalosa, ASLA, who is using her position as President of IFLA Americas, to “work globally in the service of localities. We must be humble and listen” closely to what communities want. And IFLA president Kathryn Moore said the world’s tens of thousands of landscape architects can have more impact by forming an “interdisciplinary vision” based in “common values,” particularly given the field is one of the fastest growing worldwide.
LAF President Barbara Deutsch, FASLA, and Somerville debated a bit on whether a “new narrative” was needed to achieve greater public awareness, with Deutsch calling for an entirely new set of messages, and Somerville arguing that “we are making progress with our current messages among some groups — like the older, wealthier, and better educated — but need to better reach diverse audiences. We need to get the messages out where they need to be.”
Emerging voices: Promote the next generation
With the help of Lucinda Sanders, FASLA, CEO of OLIN, the emerging voices panel assembled a group of recent LAF Olmsted scholars. An appropriate ending to a summit on “the future of landscape architecture,” these future leaders each wrote their own declarations, which they then presented to the 700-plus crowd.
Leading off was a 2015 University Olmsted scholar Joanna Karaman, Student ASLA. Now working as a landscape designer at OLIN, Karaman challenged landscape architects to “be honest about how we represent what we build.” Her work in time-based media (Karaman is also working on a film about and for the LAF Summit) seeks to bring power to the profession through the use of videos that can make more accessible the volatility and transformational potential of landscapes.
Following Karaman was Nina Chase, ASLA, senior project manager at Riverlife in Pittsburgh, who advocated for “capitalizing on the resurgence of fun” through short-term pop-up projects that can serve as prototypes and catalyze public participation. Embracing the mantra of “test before you invest,” Chase suggested that developing projects incrementally is both good for creating fun, but also for building resilience to climate change.
Scott Irvine, a 2015 University Olmsted scholar from the University of Manitoba, delivered a message from the Canadian plains, cautioning that landscape architects should beware of “becoming overly urban,” and that too often now, “regionalism stops at the edge of the city itself.” Another caution was issued by Timothy Mollette-Parks, ASLA, associate principal at Mithun, who argued that “landscape can’t be formulaic, and we must not lose our dedication as designers.”
Wrapping up the panel was the 2016 National Olmsted scholar, Azzurra Cox, Student ASLA, a recent graduate from Harvard University’s Graduate School of Design, who called for landscape architects to engage in what she calls “critical ethnography: design as a humanist, political, and narrative act.”
This guest post is by Nate Wooten, Student ASLA,2016 master’s of landscape architecture graduate, University of Pennsylvania School of Design.
“Combining ecological function and design is now mainstream,” said landscape architect Margie Ruddick, ASLA, in a talk at the National Building Museum in Washington, D.C. “It’s no longer fringe. The culture has caught up.” And it’s caught up to where Ruddick, the winner of the 2013 Cooper Hewitt National Design Award, has been for a while. A leading advocate of the “wild” landscape movement, Ruddick explained how she carefully balances ecological conservation and restoration with a strong sense of design.
In 2011, a New York Times article about Ruddick and how she was fined for growing “weeds” in her front yard in Mt. Airy, Philadelphia went “viral” among landscape architects and designers. She ultimately got out of the $75 fine by explaining to the judge the value of the wild plants she let live in her yard. “I told the judge: ‘This is actually not a weed. It’s Prunus serotina, a black cherry seedling. This is not a weed. It’s an oak tree, Quercus alba. The 10-inch weeds are rhubarb.’ ” Since then, Ruddick has become an advocate for ecological landscapes, explaining how important it is to create spaces for both people and nature.
Ruddick has turned her love of nature into a principled design approach, laid out in her new book Wild by Design: Strategies for Creating Life-enhancing Landscapes. In her talk, Ruddick walked us through some of her design principles — reinvention, restoration, conservation, regeneration, and expression — providing a few examples of each:
Reinvention: Ruddick first explained her complex project in New York City: Queens Plaza, which sits under a “tangle of elevated train infrastructure” that causes a constant, “horrible screech.” The plaza is where Riker’s Island releases prisoners at 2am with $3. It’s known as the “boulevard of death” because of the people who died trying to make it across the streets that had no crosswalks. “It was a sketchy, dangerous place.”
To make it more hospitable, Ruddick worked with a team at WRT, Marpillero Pollak Architects, and Michael Singer Studio, to find a way to embrace the infrastructure but also separate people from it with well-designed pedestrian and bicycle infrastructure and arrays of trees. New crosswalks create safe routes for pedestrians, while artful concrete obstacles were created in other places to prevent deadly jaywalking.
Meandering paths, which were calculated for different kinds of circulation, lead people to a small park. There, the surrounding trees are so effective at noise attentuation they’ve reduced the screech by 25 percent.
New bike lanes are lined with vegetation, too, so that “riding through, you feel protected from the traffic, like you are in a park.”
For Ruddick, the key to the success of the new Queens Plaza is that “it’s wild, but not unkempt.” The city was never going to pay for an irrigation system, so she created wild-looking constructed wetlands that generate their own cooler micro-climates, offsetting the heat from the street and elevated tracks.
Patterned, hand-made pavers and curbs, which were designed with artist Michael Singer, are designed to let water out into those wetlands.
Paired with the ecological function of the wetlands, there is a rugged design language that is “carefully done, but not dolled-up.” Her goal was to maintain the “industrial character of the place,” in part by replicating the massive scale of the place with heavy-duty concrete slab pathways. “The dimensions and proportions help the landscape stand up to the big scale. It doesn’t feel faux.”
Restoration: In Chengdu, Sichuan province, China, Ruddick partnered with local Chinese landscape architects to design Living Water Park, which brings back a traditional Chinese garden approach to Chengdu, long known as the “city of gardens.”
Ruddick said Living Water Park was the first park in China to be explicitly designed to provide ecological services. It’s a water purification system: fountains remove solids from the water before it heads to wetlands where it’s filter and aerated. Ruddick believes it was also the “first park in China to showcase local plants.” The result is the park “feels like a refuge.”
Conservation and Regeneration: “There are so many special places that you don’t want to mess up.” In Western Ghats, India, Ruddick restored the forest landscape in the Shilim Retreat and Institute, but the project was really about “cultural conservation” and the relationship of the local people with the ecosystem. Ruddick was thrilled to be working there: “It’s a precious range, a UNESCO World Heritage landscape, and a biodiversity hot spot. You feel like you are in heaven there.”
To the restore the environment in this 2,500 acre-resort, Ruddick first focused on the slopes stripped by erosion brought on by monsoons and local tree-cutting. To strengthen local culture, Ruddick purposefully leaned on local horticultural talent and their knowledge of how to grow plants in the Ghats environment. These locals were hired to grow thousands of trees, which were replanted on the slopes, and then to dig slopes so water could reach the saplings.
Resort rooms are carefully nestled into the landscape, and spa facilities, within the rice fields. The resort features a new institute, with a center for sustainable development.
Expression: The Durst Foundation tasked Ruddick with creating a winter garden in the Bank of America in New York City. Working with WRT, and her mother, who was a sculptor, Ruddick decided to go up to fill in the tall interior space. She wanted to create something art-filled — “that’s also very important in my work.”
Inspired by the fern canyons of the Pacific Northwest, Ruddick and her mother created vegetated sculptural forms you can walk through and around.
She said many people go there to unwind and people who frequent the garden have told her that when they are there, “their blood pressure and stress levels go down.”
While many of Ruddick’s projects exemplify multiple design principles, Ruddick pointed to the New York Aquarium in Coney Island, a wonderful project she is now working on with WRT and Cloud 9, as the prime instance of how all her nature-inspired strategies come together.
She led a team of architects from Cloud 9, a Barcelona-based firm, to create an alluring canopy of 40,000 LEDs, all blinking according to a pre-set program. The canopy is a “sculpture composed of compression arches, tension cables, masts, and hanging cable mesh.” But it’s clearly inspired by sea creatures — from a whale opening its mouth, to the scales of a fish. “A lot of research went into marine animals and that comes out in the design.”
The new perimeter is only one facet of a broader revitalization of the aquarium, which includes a new light and soundscape on the boardwalk in front of the building, surrounding gardens, and more. Ruddick and her team also laid out a vision for how to better connect the institution to its waterfront, proposing the re-use of old jetties, constructing them as tidal pools that can attract sea life, so they can serve as an environmental education center.
Many more examples of her design principles can be found in Wild by Design.
Any new studio reference book needs be beautifully illustrated. In this respect, Harvard University landscape architecture professor Niall Kirkwood, FASLA, and landscape architect Kate Kennen, ASLA, don’t disappoint with Phyto: Principles and Resources for Site Remediation and Landscape Design. But while we all like to look at beautifully-crafted, well-curated imagery, that’s not the point. This book is illuminating, a careful and coherent, critical and constructive analysis of the Phytoremediation movement, which calls for using plants to remove toxic chemicals, metals, and other contaminants from the environment.
The book begins by acknowledging an accomplished group of contributors, who bring credibility to a subject critically important but too often dismissed in the “real world.” Early on, the book provides a thoughtful sequence that explains the rationale for the book’s structure and answers the question: why are we dedicating another book to this subject?
Well, the answer is clear: because no other book has provided the thoughtful and accessible bridge long needed between theory and practice. While providing justification for the book could come off as a bit self-conscious, instead it reads as an honest depiction of an emerging field. (I also feel that if more authors were forced to go through this process of self examination, we would have both far-fewer volumes, but many-more excellent books like Phyto from which to choose).
The first two chapters cover the history and fundamentals of phytoremediation. After clearly articulating the knowledge gaps that exist in the field, the book contextualizes the movement’s early failures. Phyto then provides an expansive re-branding of the discipline, empowering potential users of these plant-based technologies to think more strategically about opportunities at hand.
The text provides a clear and comprehensive vocabulary for landscape architects and designers to use in practice. From there, the book shows how to apply these technologies in real-world situations. The book delves into common contaminants of concern and how they can be targeted with precision; a summary of planting assemblages that can be deployed in concert representing best in field technologies; and typical examples of spatial designs that produce common contaminant profiles and likely site characteristics. Variation of type and scale creates flexibility, showing landscape architects and designers how to find just the right application of phytoremediation technologies.
As knowledge-based considerations continue to find their way into public landscape design and management, inventive designers and enlightened clients interested in looking at all the alternatives would do themselves a favor by adding this book to their library and its knowledge to their practice.

Yale University and Columbia University, together with the World Economic Forum, have released the 2016 Environmental Performance Index (EPI), which tracks how well countries protect human health and ecosystems. According to their analysis, “nearly every country” has improved their “environmental performance” on 20 different indicators over the past decade, while land and marine ecosystems only continue to decline. Countries in Western Europe and North America, which already have fairly high scores, now focus on incremental improvements, but are still gaining, while even China and India have shown significant improvements from 2006. Still, the problems facing both people and ecosystems are massive. More than 3.5 billion people — half of the world’s population — live in countries with “unsafe” air quality, and around 8 percent of the global population still lacks access to clean water. On the ecosystems side: a third of all fisheries are “over-exploited” or have simply collapsed, while, in 2014 alone, an area the size of Peru, about 2.5 million square kilometers, was stripped of trees. Only 15.4 percent of terrestrial habitats and 8.4 percent of marine habitats are protected, far less than the amount Harvard biologist E.O. Wilson has called for: 50 percent of the Earth’s surface.
The world’s progress on environmental performance is wildly uneven. For example, the EPI global scorecard shows improvements in access to drinking water. The number of people who lack access to clean water has been cut in half from 960 million in 2000 to 550 million today, even as the population has increased. However, the report also shows corresponding human health failures, namely increasing air pollution. As they argued in 2012, uneven progress is due to different stages of economic development. “As nations become wealthier, particularly in Asia, their governments invest in sanitation infrastructure and fewer people are exposed to unsafe water, leading to fewer deaths from waterborne illnesses. But as countries develop, increased industrial production, shipping, and automotive transportation foul the air, exposing human populations to dangerous airborne compounds.”
In India, which is rapidly developing, 75 percent of the population is exposed to dangerous air every day. And in China, which has quickly become the second biggest economy on Earth, one in five deaths is attributed to air pollution — about 4,000 people every day. While air pollution is a critical issue in China and India, it also impacts people far beyond those two developing countries — some 3.5 billion people, or half the world’s population — live in places where fine particulate matter exceeds World Health Organization (WHO) safe standards.
Wealthy Nordic countries continue to lead the rankings, with Finland, Iceland, Sweden, Denmark at the very top, followed by European countries Slovenia, Spain, Portugal, Estonia, Malta, and France. Over the past decade, these countries show a 5-10 percent improvement in environmental performance, with model Finland improving just 3 percent over the decade, perhaps because it has already achieved such high levels of achievement. Finland, the report notes, recently passed a legally-binding resolution to receive 38 percent of their final energy from renewable sources by 2020; currently, the country already gets two-thirds of its electricity from renewable or nuclear power.
This year, the USA is in 26th place, a great improvement over 49th place in 2012 and 61st place in 2010, and a 10 percent improvement overall in performance over the past decade. President Obama’s administration has made major gains in improving air quality. Over the past decade, the administration has issued new regulations on heavy duty truck fuel efficiency and released new mercury air toxins standards, particulate matter rules, and fuel sulfur rules. President Obama has also stepped up conservation efforts, broadening the world’s largest protected marine preserve, the Pacific Remote Islands National Marine Monument, into a zone that now covers 490,000 square miles. The U.S. has done poorly on protecting its forests though, according to the index. Canada is ranked at 25, just one spot above the US.
China, the world’s second biggest economy, is ranked 109, up from 116th place in 2012. Its performance has improved nearly 13 percent over the past decade — its air quality and sanitation and waste water treatment efforts have led to gains over the past decade. And, India, the world’s most populous country, is in 141st place, slipping from 125th place in 2012, but improving 20 percent over the past decade, largely because of its improvements in sanitation and waste water treatment.
The report identifies most-improved countries — which include Comoros (48 percent), Sao Tome and Principe (38 percent), Egypt (37 percent), Djibouti (36 percent), Timor-Leste (33 percent), Lesotho (32 percent), Tanzania (31 percent) — but all are below 100 in the rankings, so they start from relatively low points. Among middle-income countries, Ukraine, Dominican Republic, Lebanon, Jordan, Greece, and Croatia have also showed big gains.
One of the few criticisms of this heroic analytical effort is the report could better highlight some of the most destructive underlying trends — namely the unabated destruction of the world’s forests, ecosystems essential to all life on earth. A stunning set of statistics: the world has lost 18 million hectares of forest each year since 2000. “The rate of global forest loss has increased in the past 15 years, up 19 percent in the period 2012 to 2014, and 42 percent compared with 2001 to 2004.” Forests, as they explain, are threatened everywhere, but most in danger in Brazil, Indonesia, the Mekong Basin in Southeast Asia, and Congo Basin in Sub-Saharan Africa. In 2014 alone, tropical forests lost 9.9 million acres of trees, an area the size of South Korea. Brazil has made strong pledges to eliminate illegal deforestation by 2030 but deforestation rates rose 16 percent last year. In other parts of the world, there aren’t even pledges to slow the destruction, as palm oil plantations and livestock farms replace forest.
Towards the end of the 100-plus-page report that accompanies the index, the team from Yale and Columbia return to their core argument, which is humanity is dramatically undervaluing the planet’s ecosystem services, and, as a result, slowly destroying its ability to sustain itself. As the authors note, “a recent study estimates that the loss of ecosystem services due to land use changes worldwide was worth between $4.3 and $20.2 trillion a year. These services contribute twice as much to human well-being than the entire gross domestic product” of the world. The authors note that a number of policymakers “already consider global biodiversity loss to be a serious threat to economic growth.” These forward-thinking policymakers understand that without forests and essential ecosystems, there is no global economy.
The EPI argues the only way forward is to decouple economic growth from the destruction of ecosystems. Natural accounting, which measures and includes the value of ecosystem services, must become the norm among governments and the private sector. Without the incorporation of the real economic value of the environment, it will be impossible for policymakers to make decisions about sustainable natural resource use. Natural accounting can be used to make the case for conservation and also restoration — what’s needed if we are to have a sustainable future.
In a landmark deal that took 20 years to reach, Canada will protect over 7.7 million acres of one of the world’s last intact temperate rainforests in coastal British Columbia. The deal protects 85 percent of the rainforest, an area about half the size of Ireland, while leaving 15 percent open to loggers who must comply with the highest sustainable forestry standards. The rainforest is home to the Spirit Bear, a rare cream-colored black bear, wolves, salmon, orcas, and miles of old-growth forest. The deal was made with 26 First Nations, which are Canadian native tribal groups, environmentalists, forest product companies, and the British Columbia government, which all called it a model of sustainable forest management. The agreement is seen as a win for the First Nation groups, who will now get a greater share of the proceeds from timber than in the past.
The deal sets new rules for timber harvesting: some 2.5 million cubic meters of forest in designated logging zones can be harvested each year. Of that amount, only 750,000 cubic meters can be cut from old growth trees. This amount may sound like a lot, but it will be 40 percent less than in the past.
In The Globe and Mail, Rick Jeffery, president and CEO of Coast Forest Products Association, called the agreement a success because it creates more certainty for the wood and paper industries. “We know what the rules are, we know what areas are going to be set aside for protection, and what areas we are going to be operating in. Knowing we have that, people can start to invest in their mills, training, and capacity. That’s the first level of certainty. The second part is that First Nations have more tenure and we are in a better position to build on those partnerships.”
Mongabay outlines the long history of conflict leading up to the agreement. In the mid-1990s, “amid growing industrial logging operations in rainforests around the world, First Nations communities in B.C. were becoming increasingly concerned about the fate of the forests in their traditional territories, to which they often had no legal title. Those First Nations groups were joined by environmentalists in a fierce battle against the forestry industry and the B.C. government until 2000, when all parties came together to call a ceasefire and allow an independent scientific analysis of the rainforest. That process culminated in the 2006 Great Bear Rainforest Agreements, a vision for ecosystem-based management of the rare temperate rainforest ecosystems found in British Columbia.”
With the just-announced agreement, the rights of First Nation communities are further bolstered, two years after a Canadian Supreme Court decision recognized their rights to stop logging in their forests. British Columbia signed 26 separate agreements with the tribes living in the forest, guaranteeing them a greater share of the proceeds from the timber harvest. These groups will now get to keep the funds from 17 percent of the annual allowable cut, up from 7 percent today.
Marilyn Slett, chief councillor of the Heiltsuk Tribal Council and president of the Coastal First Nations, told The Globe and Mail that both environmental and economic sustainability are core values of First Nation leaders and elders. “We know we must respect and care for the land and the water so they can support our communities.”
And Dallas Smith, president of the Nanwakolas Council, which speaks for eight Kwakwaka’wakw First Nations, applauded the deal, but said, alone, it won’t guarantee the long-term economic sustainability of the tribes. He told the The Vancouver Sun his people are looking beyond the agreement, looking at new ways to sustainably generate income, like “clean energy projects,” eco-tourism, and selling carbon credits for protected trees. Millions of tons of carbon are stored in those old-growth forests.
The new deal will also end the commercial hunt of Grizzly Bears within the First Nation territories of the Great Bear Rainforest, which account for about half of the total forest, but not in areas owned by the government. Ecologists have highlighted how critical Grizzly Bears and Spirit Bears are to the ecological functioning of the rainforest. BBC News explains how bears catch salmon from the rivers as the fish return home to spawn. The bears then take the salmon into the forests to eat, leaving the carcasses. When the carcasses decompose into the soil, they release much-needed nitrogen crucial to plant growth. Some 80 percent of the forest’s nitrogen comes from decomposing salmon.
There are still some critics who think the conservation agreement could have gone much further. Ian McAllister, with environmental group Pacific Wild, told The Vancouver Sun that the annual destruction of 2.5 million cubic meters of forest every year can’t be considered a win for the environment. “We simply have to find a faster transition towards the full protection of our remaining ancient forest.” A group of scientists also wanted the 20,000-hectare Gribbell Island, which is essential Spirit Bear habitat, completely protected, but it was left out of the deal.
The conservation of the Great Bear Rainforest is largely a win for the environment, but many more countries need to also engage all stakeholders in creating ecosystem-based management plans for their remaining forests. According to Yale University’s 2016 Environmental Performance Index, the world has lost 18 million hectares (44.5 million acres) of forest annually since 2000. That’s five Great Bear Rainforests every year. So many countries continue to destroy their forests unabated — with Brazil, Indonesia, and South Africa at the top of the list. As these forests are destroyed, unknown numbers of rare, niche species, perhaps less charismatic than the Spirit Bear but still incredibly valuable, face extinction.
Five cities, both large and small, and eight states were winners of the first-ever National Disaster Resilience Competition (NDRC), which was organized by the U.S. Department of Housing and Urban Development (HUD) and the Rockefeller Foundation. Communities impacted by major disasters in the past few years will receive $1 billion to develop “resilient infrastructure and housing projects.” While many projects boost resilience for coastal or river communities, there are also inland projects that aim to protect communities against fire and flooding. A majority of the projects include multi-use green infrastructure — systems that both provide flood prevention and control and public green spaces. Winning projects also focus on transit, housing, and jobs. Some 40 communities submitted proposals.
In a conference call, HUD Secretary Julian Castro said this investment in resilience will help communities become “safer, stronger, and richer” as they adapt to climate change, which is the “great challenge of the 21st century.” The past few years, he said, have seen “extreme and devastating drought, wildfires, flooding, and tornadoes.” And with 2015 now just confirmed as the hottest year on record, extreme climate events will only get worse.
Here’s a brief overview of the state and city winners, organized by the amounts they won:
Virginia: $120,549,000 for the Ohio Creek Watershed and Coastal Resilience Laboratory and Accelerator Center, which will develop “distributed green infrastructure projects, such as rain barrels and gardens, and combine them with coastal shoreline development to address flooding due to storm surge and torrential rains.”
Iowa: $96,887,177 for the Iowa Watershed Approach, an innovative program, which seeks to create local “watershed management authorities” that will assess hydrological and watershed conditions and create management plans for a more sustainable agricultural system.
Louisiana: $92,629,249 for its Louisiana Strategic Adaptations for Future Environments Program, which aims to protect coastal wetlands, retrofit communities threatened by flooding, and reshape high-ground areas. The funds will also help a tribal community on Isle de Jean Charles–whose land has submerged by an amazing 98 percent since 1955–move to a new location.
California: $70,359,459 to pilot its Community and Watershed Resilience program in Tuolumne county, which was hit by wildfires in 2013. The program aims to create a environmentally and economically sustainable model for forest and watershed health that can be rolled out across the state.
Connecticut: $54,277,359 for a pilot program in the city of Bridgeport to test the state’s broader Connecticut Connections Coastal Resilience Plan, which seeks to connect “economically-isolated” coastal communities through a mix of green and gray infrastructure.
Tennessee: $44,502,374 for the state’s Rural by Nature, a federal, state, and local initiative to create resilient rural communities along the Mississippi River, which will restore two miles of degraded floodplain.
New York: $35,800,000 for public housing resiliency pilot projects throughout the state, which will test efforts to build resilience into low-income multi-family housing.
New Jersey: $15,000,000 for a regional resilience planning grant program, which will help local communities create their own plans to address their vulnerability to flooding.
New York City: $176,000,000 for coastal resilience in Lower Manhattan and efforts to protect public housing projects.
New Orleans: $141,260,569 for the city’s first-ever Resilience District in Gentilly, which will include coastal restoration, new parks and green streets, and workforce development initiatives.
Minot, North Dakota: $74,340,770 for an integrated approach to manage climate change and flooding.
Shelby County, Tennessee: $60,445,163 for its Greenprint for Resilience program, which will build a connective set of green infrastructure projects to increase protection against future flooding while creating trails and recreation areas.
Springfield, Massachusetts: $17,056,880 for an Urban Watershed Resilience Zone, which will focus on jobs, restoring affordable housing, and the creation of a new distributed heat and power plant in the event of a grid failure.
Green infrastructure, which involves using designed natural systems to provide a range of ecosystem services, is a primary area of investment, said Harriet Tregoning, who leads resilience efforts at HUD. “Lots of the projects feature green infrastructure. But we used a benefit-cost analysis to ensure that green infrastructure offers more than one benefit–not just stormwater management.” As Tregoning explained, HUD encouraged the project teams to come up with ways that “green infrastructure for stormwater managment or flood control could double as a park or greenway, bicycle or walking path.” The goal is to “capture all the social co-benefits.”
Christian Gabriel, ASLA national design director for landscape architecture at the General Services Administration (GSA) and one of the evaluators of the proposals, argued that the process also encouraged new approaches to deal with these complex, multi-faceted problems: “Great planning and design necessarily cross political and geographic jurisdictions. When multi-purpose projects are conceived from inception as trans-disciplinary, they more effectively act as force multipliers in communities.”
He added that the “competition asked proposers to not only provide compelling physical solutions but also propose new working relationships and create resilient models for collaborative work between governments and civil society.”
While the $1 billion is a drop in the bucket in terms of what’s needed, NDRC is an important expansion of the Rebuild by Design competition, which dedicated $920 million to improve the resilience of the communities hit hardest by Hurricane Sandy, as it may show this competitive financing model can work nationally as well. The NDRC involved some 25 federal agencies, including 100 experts, and it took 16 months to review the proposals and select the winners. What’s needed in the future is a scaled-up annual process, which is something we hope the next administration will take up.
Many more communities need help with resilience, or there will soon be more Isle de Jean Charles, more looking for a new home.
A newly expanded and now mobile-friendly version of ASLA’s Designing Our Future: Sustainable Landscapes online exhibition highlights real-world examples of sustainable landscape design and its positive effects on the environment and quality of life. These spaces use natural systems to provide ecosystem services, transform untapped assets into vital community spaces, and create new economic opportunities — they ultimately provide significant environmental, social, and economic value.
Ten new case studies that range from a coastal ecological restoration project to a volunteer-run urban farm illustrate just what sustainable landscapes are and how they provide important benefits on a variety of scales. In the process, the case studies, written in clear, understandable language, also introduce users to what exactly landscape architects do.
The new case studies were carefully selected to show a diversity of landscape types and scales and reflect geographical diversity. There are now a total of 40 case studies.
Lafayette Greens, Detroit, Michigan, a volunteer-run urban farm in downtown Detroit where 800 pounds of fresh fruit and vegetables are grown every year.
Living Breakwaters, New York, New York, an innovative coastal ecological restoration project that won $60 million in the Rebuild by Design competition sponsored by the U.S. Department of Housing and Urban Development (HUD).
