ASLA Statement on the Green New Deal

Green New Deal launch on Capitol Hill / WIkipedia

Significant Overlap Seen Between ASLA’s Report, Smart Policies for a Changing Climate, and Many Provisions of the Green New Deal Resolution

A wide-ranging proposal for a Green New Deal (GND) was introduced on February 7 in the House of Representatives in the form of a resolution sponsored by Rep. Alexandria Ocasio-Cortez (N.Y.), with a companion resolution introduced in the Senate by Sen. Edward Markey (Mass.).

Although the current GND resolution is largely aspirational and includes few specific policies, it contains a commitment to core principles of urgent transformational change that are fully compatible with ASLA’s positions, and mirror the recommendations the Society already put forward in our Blue Ribbon Panel report, Smart Policies for a Changing Climate.

Like our report, the GND resolution calls for widespread, immediate action that will ensure clean air and water; climate and community resiliency; access to nature; and a sustainable environment. We also strongly back calls for a national commitment to environmental justice for all Americans, especially for those from underserved, vulnerable, and neglected groups that have historically borne the brunt of the ill-effects of environmental calamities. ASLA supports the underlying principles of the GND resolution that relate specifically to climate change and resilience, and we are pleased that it has served to stimulate public debate about the accelerating climate crisis.

We note that in addition to climate-related policies, the resolution also contains several recommendations about social and economic issues that are beyond the scope of the Society’s mandate and existing policies, matters about which we can take no formal position.

ASLA members can be assured that when the GND is translated into formal legislative proposals to reduce carbon emissions, make transformational changes to infrastructure, and create a robust 21st-century clean-energy economy, ASLA will be at the forefront of the fight to enact them into law. We firmly believe that landscape architects must take a leadership role in planning and designing sustainable, resilient communities and ASLA, without question, will do its part to bring the climate principles of the Green New Deal to fruition.

ASLA is pleased that the Green New Deal resolution has significantly expanded the scope and intensity of the dialogue about climate change and we are extremely gratified that the Society’s report mirrors its major climate and infrastructure goals and we look forward to the legislative proposals that will stem from it.

Shadow-Casted Artwork Tells the Story of Time on an Indian Street

We can feel the passage of time as we watch the sun chart its course across the sky. But we have also become accustomed to the daily arc of our closest star. To bring the movement of the sun — and the progression of time — into the foreground, Indian street artist Daku leveraged the sun’s shadow-casting power to create a temporary installation — Theories of Time — for the St+art India art festival along a commercial street in Panjim, Goa.

A street-long awning holds up stenciled adages that project shadows forming a tapestry of words on the ground: “Things take time; time is a great teacher; time heals all wounds; lost time is never found again.”

Light, shadow, and words figure in earlier works as well. In 2016, Daku created Time Changes Everything, installing words on the side of a white-faced building, letting the movement of the sun form and then slowly disintegrate words like ability, hour, definition.

The artist seems to enjoy incorporating surprising words and sentiments into the built environment — in particular humorous messages aimed at motorists.

Daku’s shadow-casting artwork adds an interesting layer to the streetscape and offers an approach filled with possibilities for other public spaces.

Robots Produce World’s Longest 3D-Printed Concrete Bridge

3D printed concrete bridge / JCDA

During the Sui dynasty, it took a decade for master craftsman Li Chun to build the Anji stone bridge in southern Hebei province. Some 1,400 years later, Tsinghua University robotics professor Xu Weiguo copied the structure in just 19 days, with the assistance of robots 3D printing in concrete. The resulting engineering marvel — an 86-feet-long, 12-feet-wide bridge in the Boashan district of Shanghai — uses a single load-bearing arch, just like Anji.

Robotic arms swung back and forth for some 450 hours, fulfilling the demands of their algorithms. The robots were programmed to follow separate models of the arch structure, fence, and deck, yielding some 176 uniquely-shaped pieces, which were then slotted into place.

The hyper-real, curvilinear, machine asthetic of many 3D modeled objects is also found in this bridge. On the deck, a brain coral pattern filled with fine stones add some warmth, bringing the feel of traditional Chinese garden path.

According to Tsinghua University, the 3D printed bridge costs just two-thirds the price of a bridge produced the conventional way.

Professor Xu and his team at the Tsinghua University School of Architecture’s Zoina Land Joint Research Center for Digital Architecture (JCDA) tested the bridge design using a 1:4 scale model to ensure it would bear the weight of pedestrians. And for extra safety, they built in a real-time monitoring system. Wires and sensors embedded throughout the structure send a constant stream of data on the performance of the bridge.

ArchDaily notes the world’s first 3D printed steel bridge just debuted in The Netherlands, and Columbia Unversity has been experimenting with 3D printing timber lookalikes. Like other sectors, construction may soon become more automated.

The U.S. Army Corps of Engineers Turns to Nature

Engineering with Nature: An Atlas / U.S. Army Corps of Engineers

“We rely on natural processes and landscapes to sustain human life and well-being. Our energy, water, infrastructure, and agricultural systems use these processes and landscapes to satisfy our most basic human needs. One motivation, therefore, for protecting the environment is to sustain the ecosystem goods and services upon which we depend. As we emerge from the sixth decade of modern environmentalism, there is a growing international awareness of opportunities to efficiently and effectively integrate natural and engineered systems to create even more value.”

One might understandably think this was written by a landscape architect, or excerpted from somewhere on the ASLA website. In fact, it comes from the forward of Engineering with Nature: An Atlas, a new book by the U.S. Army Corps of Engineers (USACE) Engineering with Nature (EWN) team, led by environmental scientist Dr. Todd Bridges. 

Over the last eight years, Bridges has quietly built the EWN initiative out of the Army Corps’ Vicksburg, Mississippi headquarters, working with a team of engineers, environmental scientists, and ecologists to develop pilot projects that prove the viability of engineering large-scale infrastructure in partnership with natural systems. 

Now, after successfully completing dozens of projects across the U.S., Bridges is pushing to take EWN to new heights. The initiative’s 2018-2023 strategic plan envisions an expanded portfolio of engineering strategies and project types, deeper interdisciplinary and community engagement, and heightened public awareness of EWN goals, activities, and success stories.

To that end, Engineering With Nature: An Atlas documents more than 50 engineering projects completed in recent decades that exemplify the EWN approach. The projects are grouped according to typology, including chapters on beaches, wetlands, islands, reefs, and rivers. Reflecting the collaborative approach of the EWN initiative, only half of the case studies profiled were carried out by the Army Corps. The remainder were executed by partner NGOs in the US and government agencies in England, The Netherlands, and New Zealand, countries which have made substantial investments of their own in innovative coastal and water-based engineering.

A key theme of the book is the beneficial re-use of dredged material. While conventionally viewed as a waste product, the EWN initiative seeks to find and develop beneficial uses for the material, such as in wetland restoration, habitat creation, and beach nourishment. And because the Corps is required to maintain the navigability of all federal waterways, the EWN team has a ready supply of dredged material to work with.

One example of this strategy can be seen in Texas’ Galveston Bay, where the Corps partnered with Houston Audubon to create the 6-acre Evia Island, which today is populated with herons, egrets, terns, and brown pelicans.

Other projects take advantage of erosion and sediment flux to catalyze beneficial outcomes. In Louisiana’s Atchafalaya River, the Corps placed dredged material in strategic upriver locations to create a 35-hectare island that is “self-designed” by the river’s flow. And at Sears Point, in the northern San Francisco Bay, the Sonomoa Land Trust and Ducks Unlimited restored 1,000 acres of tidal marsh by puncturing a levee, allowing water from the Tolay Creek to flow into a field of constructed sediment mounds. The mounds slowed the water’s rate of flow, stimulating land growth within the project area.

These approaches have considerable overlap with recent research in the field of landscape architecture, particularly the work of the Dredge Research Collaborative, which advocates for ecological and watershed-scale approaches to the management of sediment and dredged material and has collaborated with the EWN initiative in recent years.

An Atlas also includes projects that retrofit conventional infrastructure to provide ecological benefits, such as creating nesting habitat for terns on top of breakwaters in Lake Erie, or efforts in the Netherlands to redesign coastal reinforcements to serve as habitat for marine plants and animals. Reminiscent of SCAPE’s Living Breakwaters project off the southern coast of Staten Island, these projects demonstrate an increasing interest in designing infrastructure that provides multiple benefits.

Despite its title, At Atlas does not contain any maps or diagrams to orient the reader–an unfortunate omission that makes it difficult to grasp the scale of the presented projects. Instead, the projects are depicted using solely perspective and aerial photos.

While these photos are informative, the book would have greatly benefited from the development of a graphic language to more clearly and visually communicate the impacts of the presented projects and the issues they seek to address.

Despite these omissions, the breadth and scope of projects presented in Engineering with Nature: An Atlas makes a considerable impression, presenting a range of strategies for designing infrastructure with ecological, social, and cultural benefits at multiple scales.

Perhaps most significantly, An Atlas suggests there is great potential for meaningful interdisciplinary collaboration between the Corps and landscape architects. As landscape architects increasingly seek to broaden the field’s scope to include the planning and design of large-scale systems and ecologies, this collaboration may prove vital. Engineering with Nature: An Atlas begins to paint a picture of what such a collaborative practice may look like.

Landscape Architects Take the Lead on New Cultural District in Detroit

DIA Plaza and Midtown Connections design competition presentation at Detroit Institute of Arts (DIA) / DIA Plaza Midtown Cultural Connections

In Detroit, twelve arts, cultural, and educational institutions are clustered together geographically, but have failed to form a unified district, a true destination. The Detroit Institute of Arts (DIA) and the Midtown Detroit Inc, hope that a new central public space around the DIA and a broader urban design to boost connectivity and accessibility can change that. In an attempt to create a coherent, inclusive, accessible, and sustainable district that can attract both residents and tourists, DIA and Midtown launched an international design competition last year, which has since yielded three finalists that presented to some 200 local residents at the DIA last week.

More than 40 submissions from 10 countries were narrowed down to eight finalists. And now it’s down to three interdisciplinary teams led by landscape architecture firms: Agence Ter from Paris, France; Mikyoung Kim Design from Boston, Massachusetts; and TEN x TEN, which is based in Minneapolis, Minnesota.

According to the DIA and Midtown Detroit, Inc, who worked with the twelve educational and cultural institutions, the finalists’ proposals are the result of a year of input from committees and residents, which participated through 40 public engagement sessions.

Finalists presented to the competition jury at the DIA, which includes Salvador Salort-Pons, president of the DIA; Maurice Cox, Detroit’s planning director; and landscape architect Julie Bargmann, ASLA, founder of D.I.R.T. Studio.

All the teams seek to shrink down the width of boulevards; remove parking; add event spaces, cafes, and public art installations; and vastly expand public green space. The new designs could be the National Mall of Detroit or a lush, interactive university campus. The design teams seek to bring people in from around the Detroit and the suburbs and keep them there, engaged, enlightened, and entertained year-round.

The Agence Ter team offered meandering paths through forested and planted areas, with experimental event spaces for local artists and public art installations that speak to Detroit’s unique history.

The Mikyoung Kim Design team envisioned a verdant space, with a central lawn that can host events, as well as an outdoor movie screen, cafe, playground, and maze garden that converts into an ice rink in winter.

An exhibition of the proposals is on view at the DIA until April 1. The winning proposal will be announced by the end of April.

This incredible investment in raising Detroit’s profile as a cultural mecca can only help this city get back on its feet after years of disinvestment and near bankruptcy. Only a few years ago, the city seriously considered selling off the amazing art at the DIA to pay down debt. The message of this project is inclusive cultural and ecological revitalization is the new way to do urban revitalization.

Design Competition: Public Art That Produces Energy

Light Up, 1st Place Winner, LAGI 2018 Melbourne competition / LAGI

The inventive folks behind the Land Art Generator Initiative (LAGI) seek to make renewable energy beautiful. They want to integrate clean power sources into public art and the broader public realm, sending a powerful civic signal — that we can achieve a more sustainable commons and world.

For their competition this year, LAGI seeks a work of energy-producing art for a site within Masdar City, Abu Dhabi, a planned community designed by Foster and Partners in the United Arab Emirates. Masdar City is expected to be completed by 2025 and become home to some 50,000 people and 1,500 clean-tech and sustainable businesses.

According to LAGI, Masdar is the Arabic word for “source” — and in this case, refers to the sun, the source of power for the ambitious development. The city plans to get most of its energy from nearby solar facilities, which are being built with specialized solar panels that can survive sand storms. Masdar will also recycle some 80 percent of its water.

The competition is organized in partnership with the 24th World Energy Congress, which will host presentations of the 25 shortlisted finalists. Winners will receive $40,000 and the runner-up, $10,000. See the winners from last year’s competition in Melbourne, Australia.

Interdisciplinary teams can submit designs by May 12, 2019.

Another competition worth checking out: Gauja National Park, the largest national park in Latvia at some 917 square kilometers, seeks a new footbridge, a symbolic gateway to mark the park’s 45th anniversary. First place winners will receive $3,000. No professional qualifications are required. Submissions are due June 11, 2019.

The Pioneers of Postwar Landscape Architecture

Shaping the Postwar Landscape / University of Virginia Press

Shaping the Postwar Landscape, edited by Charles Birnbaum, FASLA, founder and CEO of the Cultural Landscape Foundation (TCLF), and Scott Craver is the fifth in a series of books that serve as an encyclopedia of landscape architects and allied professionals who made significant contributions to American landscape design. The book is an excellent resource for anyone interested in American landscape design’s roots.

While the editors set out to provide a reference guide, they’ve achieved a relatively compelling read. Professional disciplines are comprised of people, ideas, and projects. Through the fastidious profiling of American landscape pioneers, Birnbaum and Craver have encapsulated a specific period of landscape architecture in an easily consumable text.

Per the title, the book focuses on landscape architects who were most active post-WWII through the bicentennial. This was the era of Modernist design and the move to incorporate environmental intelligence into design and planning. This era saw the first freeway-capping parks, rooftop gardens, and waterfront revitalization projects. And saw landscapes architects take on a broader range of projects in new territories and at new scales, from urban pocket parcels to suburban developments to greater ecological regions.

It was also a time in which the profession of landscape architecture experienced impressive growth. ASLA members numbered 540 in 1949, a figure that leaped to over 4,000 by 1974, according to Elizabeth Meyer, FASLA. With that growth came added diversity and strength of ideas. More women, minorities, and people without professional backgrounds in landscape architecture took on roles in shaping the discipline during this period. The individuals chronicled in the book are those whose professional and academic work guided and informed landscape architecture during an especially exciting time.

Postwar Landscapes’ profiles are well-written and include useful personal and professional information as well as analysis. For instance, we are told not only what projects landscape architect Satoru Nishita worked on, but of the renown of his father’s bonsai and that his portfolio demonstrated a keen eye for design details. In this way the writing avoids dryness in spite of the book’s encyclopedic format. The format does have the benefit of allowing one to telescope in and out of the book. But as one reads through, names of people, projects, institutions and movements recur to the point that one begins to recognize the larger constellation they form.

While Postwar Landscape’s format might suggest it’s suitable only for researchers, its reach should be much greater. Many landscape architects are well-versed on projects but fuzzy on the associated names and chronology. This book is an excellent tool for filling those gaps.

If you know of Lafayette Park in Detroit but not Alfred Caldwell, or admire Cornelia Oberlander’s work but want to understand her broader impact on the profession, Postwar Landscapes can be a rewarding read.

As founder and CEO of the Cultural Landscape Foundation, few individuals have done more to increase awareness of American landscape design than Birnbaum. His crusade has produced the sort of work that edifies and anchors a discipline, work that should not be taken for granted.

Forest Bathing Goes Global

Shinrin Yoku: The Japanese Art of Forest Bathing / Timber Press

For thousands of years, humans have purposefully immersed themselves in forests in order to revitalize their spiritual, mental, and physical health. But in 1982, Tomohide Akiyama, director of Japan’s forestry agency, put a name to this, coining the term shinrin yoku, which can be translated as forest bathing. Since then, interest in the practice has skyrocketed among both the public and scientific researchers. And last year, forest bathing may have hit a tipping point, with four books published around the world on this natural therapeutic approach. Forest bathing seems poised to go global, as interest expands beyond Japan into South Korea, the rest of Asia, and throughout the West.

In Shinrin Yoku, The Japanese Art of Forest Bathing, Yoshifumi Miyazaki — who is a professor at the Chiba University center for environment, health, and field sciences; coiner of the term “forest therapy;” and one of the first to conduct scientific research on the health benefits of forest immersion — we have the original Japanese take on the practice.

In Japan, forest bathing and the more-regimented, often multi-day practice of forest therapy are mainstream. Companies regularly send their employees to forests to restore themselves. And Japanese go on therapeutic vacations to some of the most well-known sites of natural beauty. Today, there are some 60 official forest therapy trails, designated for the practice of shinrin yoku by the Forest Therapy Society. And there are a growing number of doctors who are certified to practice forest medicine.

Over the course of human evolution, we have spent 99.99 percent of our development in natural environments. It’s only very recently that we have, as a species, moved into dense urban areas. According to Miyazaki, this has resulted in major health issues. “We are over-stimulated and stressed by today’s man-made world, and that makes our bodies more susceptible to disease.” For him, “it’s not surprising that attention is turning to shinrin yoku as an example of a natural and low-cost way to alleviate this problem.”

In 1990, Miyazaki conducted some of the first experiments to examine the physiological effects of forest bathing on the Japanese island of Yakashima. The study had limited value because then only saliva samples measuring cortisol levels were used. Since 2000, though, the science “moved on,” yielding new ways to measure brain activity and autonomous nervous activity, “both good indicators of the level of stress in the human body.” Over the past 10-15 years, data on the benefits of forest bathing has accumulated.

Miyazaki does an excellent job of clearly communicating the dangers of stress and how forest therapy helps reduce its impacts.

Our over-stimulated urban lifestyles leads to chronic stress, which is exacerbated by “technostress,” the unique stress caused by our fixation on smart phones, twitter feeds, and Netflix accounts.

According to Miyazaki, stress causes illness such as the common cold; back, neck, and shoulder pain; slower healing; weight gain and loss, sleep dysfunction; depression; dysautonomia (autonomic nervous disorder); irritable bowel syndrome; ulcers and stomach problems; heart diseases; and increased cancer risks.

Forest therapy increases physiological relaxation, boosting our immune system and undoing the damaging effects of stress.

The benefits of forest therapy measured by Mizayaki and others include:

  • “Improvement of weakened immunity, with an increase in the count of killer (NK) cells, which are known to fight tumors and infections.
  • Increased relaxation of the body due to increased activity in the parasympathetic nervous system activity.
  • Reduction in blood pressure after only 15 minutes of forest therapy.
  • Reduced feelings of stress and a general sense of well-being.
  • Reduction in blood pressure after 1 day of forest therapy, which lasts up to 5 days after therapy.”

On a deeper level, Miyazaki believes we experience these benefits when we de-synchronize with technology and the stressful pace of urban living and re-synchronize with the natural rhythms we have evolved with. Over seven million years of human evolution, “we have lived amid nature and our bodies have adapted to that nature.”

In Japan, there is a deep connection with nature. From the country-wide festivals under the beautiful, ephemeral cherry blossoms to the prayers left at the base of honored tree specimens, Japanese live with nature, as opposed to admiring it as the other. People and the natural world co-exist in a country still covered in nearly 70 percent forest. It makes sense then that the Japanese government invested greatly in research on forest therapy, some $4.3 million since 2004.

One study was conducted in 63 forests across Japan, using some 756 subjects, who were split into 6 groups in different regions. Within each group, half went to urban areas and half were sent to forested areas. Subjects were asked to walk slowly through an urban or forested environment for 15 minutes in the morning, and then just sit and look at the view for 15 minutes in the afternoon. Their autonomic nervous activity, pulse rate, blood pressure, cortisol levels were measured, and they were asked questions about how they felt. The study proved that “during forest therapy, the body experiences physiological relaxation.” And subjects in the forested areas reported an increased feeling of comfort, calm, and refreshment; an improvement in their emotional state; and reduction in anxiety.

Other studies in Japan showed that a forest therapy session reduced blood pressure among men with high blood pressure and office workers; calmed pre-frontal brain activity; and among mature women, reduced stress levels. Furthermore, if a forest isn’t accessible, spending time in a large urban park, looking at ornamental house plants, flower arrangements, or bonsai trees, or smelling wood also relaxes the body.

The book is also worthwhile as a guide to shinrin yoku on your own. Miyazaki explains how to walk mindfully in the forest, feeling the forest floor, taking in the sounds and smells, or closely studying a tree. For a therapeutic boost, he recommends meditating, stretching, or sketching in a forest.
