Many of the sessions will also qualify for continuing education credit with the Green Building Certification Institute (toward LEED AP credential maintenance), the American Institute of Architects, the American Institute of Certified Planners, and other allied professional organizations and state registration boards.
Education session speakers selected from this process will receive a full complimentary registration to the ASLA 2018 Annual Meeting and may also be eligible for reimbursement for one night’s hotel stay at an official ASLA hotel (an estimated $750 value). Landscape architecture professionals wishing to present at the Philadelphia meeting need to be active members of ASLA. Allied professionals are encouraged to both submit presentations and speak but are not required to be members of the Society.
Whether you are looking for a unique book to give as a gift or just one for yourself to delve into, we have some options. Here’s THE DIRT‘s top 10 books of 2017, our picks for the best on the environment, cities, and landscape:
Drawdown: The Most Comprehensive Plan Ever Proposed to Reverse Global Warming (Penguin Press, 2017)
Author and environmental activist Paul Hawken assembled hundreds of experts around the world to rank the potential positive impacts of 100 substantive climate solutions. One of the most accessible and informative books on climate change, Drawdown makes clear the vital role of landscape architecture, architecture, and urban planning in finding a way to reduce greenhouse gas emissions. Hawken and his coalition consider complete streets and bicycle infrastructure, walkable cities, green roofs, composting systems, and net-zero buildings as critically important. Other top solutions — like educating girls in developing countries and silvopasture — will cause you to think more about the relationships between population, agriculture, and sustainability.
Be Seated (Applied Research and Design Publishing, 2017)
In his new book, Laurie Olin, FASLA, founder of the landscape architecture firm OLIN and this year’s Vincent Scully Prize winner, brings to life his deep interest in outdoor seating. As he describes: “My interest in public outdoor seating in parks and plazas revolves around two poles: one is related to the fascination that Emerson and other philosophers have shown regarding aspects of the quotidian in our lives and experience, its pressures and benefits; the other is the utility of public seating in guiding our conduct as citizens.” Scattered throughout are evocative sketches and water-colors and well-curated images. If you enjoy trying to figure out what makes a public space great, you’ll love this book.
The Color of Law: A Forgotten History of How Our Government Segregated America (Liveright, 2017)
Richard Rothstein, an authority on housing policy, “explodes the myth that America’s cities came to be racially divided through de facto segregation―that is, through individual prejudices, income differences, or the actions of private institutions like banks and real estate agencies. Rather, The Color of Law incontrovertibly makes clear that it was de jure segregation―the laws and policy decisions passed by local, state, and federal governments―that actually promoted the discriminatory patterns that continue to this day.” As American cities continue to address the legacy of segregation while also dealing with widespread gentrification, this new look at urban history is invaluable.
Extreme Cities: The Peril and Promise of Urban Life in the Age of Climate Change (Verso, 2017)
Ashley Dawson, a professor of English at the City University of New York, argues that mega-cities, which are most often found on coasts, are “ground zero for climate change,” given they are home to our largest populations, highly vulnerable, and also contribute the most to greenhouse gas emissions. Reviewing Extreme Cities, author McKenzie Wark writes: “Dawson shows how social movements have combined action on disaster relief with forms of equitable common life to produce models for radical adaptation from which we can all learn. This is a brilliant summation of what we know and what we can do to build a new kind of city in the ruins of the old.”
Handbook of Biophilic City Planning & Design (Island Press, 2017)
University of Virginia professor Tim Beatley’s new book presents everything he has discovered on what he calls “biophilic urban planning and design” — strategies that both boost biodiversity and foster deeper human connections with nature in cities. He brings together the established science, the important case studies, and innovative code and design practices from around the world in one place. Even if you think you already know a lot about how best to incorporate nature into cities, there will be some interesting new facets in this book for you to explore. (Read the full review).
Movement and Meaning: The Landscapes of Hoerr Schaudt(The Monacelli Press, 2017)
This book highlights the depth of work created by landscape architects Doug Hoerr, FASLA, and the late Peter Schaudt, FASLA. From private gardens to lush civic spaces, Movement and Meaning chronicles the major works by the Chicago-based studio, from inception to final installation. The sheer variety of images, drawings, and photography make this book an absorbing overview. (Read the full review).
Paradoxes of Green: Landscapes of a City-State (University of California Press, 2017)
This new book by Gareth Doherty, ASLA, director of the masters in landscape architecture program at Harvard University Graduate School of Design, is a successful hybrid of landscape writing and ethnography focused on the island nation of Bahrain. It presents a portrait of Bahrainis’ rich and evolving relationship with their landscape as well as a model for future studies. (Read the full review).
Transmaterial Next: A Catalog of Materials That Define Our Future (Princeton Architectural Press, 2017)
While we have all experienced the effects of the information technology revolution now underway, we may be less aware of the impact of the new “materials revolution,” argues University of Minnesota professor Blaine Brownell in his new book. Building materials are being transformed to respond to our planetary environmental crisis, lower costs and boost efficiency, and provide new media for creative expression. Given the serious problems facing the Earth, the scale of the ambition is heartening. (Read the full review).
Wise Trees (Harry N. Abrams, 2017)
Landscape photographers Diane Cook and Len Jenshel offer gorgeous full-page photographs of 50-plus wise, old trees, which are accompanied by a brief story about the spiritual and cultural life inspired by each of these natural wonders. With the help of grants from the Expedition Council of the National Geographic Society, the photographers spent two years traveling across five continents to capture these historic specimens.
Also, worth knowing: buying these books through THE DIRT or ASLA’s online bookstorebenefits ASLA educational programs. And if you are based near Washington, D.C. we also recommend checking out the National Building Museum’s fantastic book store.
“We are at a momentary bizarre development in the course of human affairs,” said former President Bill Clinton at the opening plenary of the 2017 Greenbuild in Boston, where there are facts and “alternative facts.”
What’s very worrying for him: Democracy itself rests on facts, which are the basis of agreement and cooperation. In our system of government, “the most important thing is how we think.” Only when we share common faith in the same facts can we “come together do the right thing.”
If how we think is corrupted, “the system can be permanently altered.” American democracy itself, he seemed to say, is now at risk.
For Clinton, who spoke to thousands of architects, landscape architects, and other green industry professionals, a model for how to think is offered by biologist E.O. Wilson.
But Wilson also tells us that “humans are arrogant and close to destroying the Earth. We have to wake up before the car hits the brick wall.” We need to wake up so “we can go onto a higher level of achievement.”
That higher level of achievement is “the positive-sum game in which everyone wins — the slow, steady rise of cooperation, which has been the path of human history.”
Clinton believes the green industry itself acts as a democracy — with multiple coalitions coming together to create rating systems, like LEED and the Sustainable SITES Initiative® SITES®, and new models for solving problems. The green industry can then help forge a new path in which everyone wins.
As U.S. Green Building Council (USGBC) president Mahesh Ramanujam argued, “everyone deserves the benefits of sustainable living.”
After three years of flat carbon dioxide emissions, the burning of fossil fuels is expected to reach a record high in 2017, increasing global CO2 emissions by 2 percent to 41 billion tons. According to the Global Carbon Project, which published its findings in three scientific journals, the increase is driven in part by rising coal use in China. The report authors note, however, that there are uncertainties in the data, and actual growth figure could be anywhere from 0.8 to 3 percent.
To keep the global carbon dioxide ppm levels below 450, which corresponds to a 2 degrees Celsius (3.6 degrees Fahrenheit) temperature increase, countries party to the Paris climate accord agreed to reach peak emissions by 2020 — with China and India given another decade — and then decline to zero emissions by the end of the century.
The Guardian writes: “whether the anticipated increase in CO2 emissions in 2017 is just a blip that is followed by a falling trend, or is the start of a worrying upward trend, remains to be seen.”
China’s emissions, which account for nearly a third of the total, are estimated to rise this year by 3.5 percent, as local governments invested in construction and infrastructure projects to boost economic growth.
On Chinese emissions, Lauri Myllyvirta, Greenpeace climate and energy campaigner, told The Wire: “This year many local governments reverted to the old playbook of using infrastructure and construction projects to create demand and prop up local economies. In many regions that has meant rolling back on the restructuring of the economy and an uptick in smokestack industry output.”
U.S. emissions are down just 0.4 percent, a fall from an average reduction of 1.2 percent over the past decade. The New York Times writes: “Much of the fall in American emissions has come as increasing supplies of natural gas, wind and solar power have driven hundreds of coal plants into retirement. But emissions from sectors like transportation and buildings remain stubbornly high, and with the Trump administration dismantling domestic climate policies, it is unclear how far the country’s emissions will continue to fall in the coming years.”
And EU emissions reductions in 2017 — just 0.2 percent — are significantly lower than the 2.2 percent decline seen over the past decade. This is especially worrying as Europe bills itself as a climate leader.
There are some positive trends though: India’s emissions grew just 2 percent, down from the 6 percent average seen over the past decade. In total, The New York Times reports, “at least 21 countries have managed to cut their emissions significantly while growing their economies over the past decade, including the United States, Britain, France, Germany, and Sweden. These countries have steadily transitioned away from energy-intensive industries — or have outsourced manufacturing to countries like China — while increasing investments in efficiency and cleaner energy.”
The signatories of the Paris climate accord are now meeting in Bonn, Germany, to review and hopefully ratchet up the voluntary commitments each country makes to reduce their carbon emissions. Causing protests, the Trump administration hosted a panel promoting coal and nuclear power, which included a delegation of fossil fuel executives. Former Vice President Al Gore and other Democratic senators and governors also staged an “anti-Trump revolt” at the conference, arguing the federal government doesn’t represent all of the U.S., and many cities and states are still aiming to achieve the U.S.’s prior commitments made under Obama.
Meanwhile, Global Carbon Project lead researcher Corinne Le Quéré, a professor at the University of East Anglia, told Wired more countries must follow Britain’s lead if the world is going to reach zero emissions between 2050 and 2100. To do so, they need to enact tough legislation that requires reductions: “The world needs to follow by the UK’s example. The Climate Change Act commits us to reducing our CO2 emissions by 80 per cent of what they were in 1990. If every nation had one of those, by 2050 we will be well on the way to a low carbon economy globally.”
How can landscape architects ensure the spaces they design perform they way they were intended? Landscape architects need site commissioning to accurately determine the performance and impact of their designs.
Site commissioning is the process by which performance standards are established, then measured and verified overtime. The topic has been gaining traction within the field and was the focus of a discussion at the ASLA Annual Meeting in Los Angeles put together by Jose Alminana, FASLA, principal at Andropogon Associates; Christian Gabriel, ASLA, national design director of landscape architecture at the U.S. General Services Administration (GSA); Lauren Mandel, ASLA, landscape architect and integrated researcher at Andropogon; and Maureen Alonso, regional horticulturalist with the U.S. GSA National Capital.
The discussion comes on the heels of a comprehensive new report released this summer by the GSA with Andropogon that makes the case for site commissioning.
“This is something long overdue — it’s a logical follow up to the kinds of values and capacity we expect to obtain from the work that we do — the impact our profession can really have on the systems on which we all depend,” Alminana said.
Currently, buildings are analyzed and commissioned to ensure the quality and function of a project. “Landscapes, if they are going to play that kind of role, also need to be commissioned,” Alminana said. “But it gets complicated, because its not about moving parts and on and off switches. It’s about life, and life that is always evolving and changing.”
Site commissioning pushes the integration of building systems and site systems and establishes a role for the landscape architect early on in the project. Alminana said designers need to first define the goals and objectives of the project and the standards they are trying to meet. The expected environmental and economic benefits of a landscape project need to be clear, and there needs to be metrics to measure performance in achieving those benefits.
“There has been, over the past few decades, an interest in developing site-responsive projects, but there is less definitive knowledge as to what we are actually achieving, how we set our goals, and how we factor processes into broader project delivery methods in design and construction,” Gabriel said.
“The time has come to reinvest in our own processes,” he said, adding that site commissioning could result in a paradigm shift in the field, “and a return to landscape as prime method for conceptualizing new opportunities.”
Mandel explained the process of developing the report, which included learning from case studies of commissioned projects or those with robust site monitoring. One example is the Clark Art Institute in Williamstown, Massachusetts by Reed Hilderbrand, which commissioned a complex hydrological system.
“Site commissioning offers strong triple bottom-line benefits,” she said, listing social benefits, like worker productivity; environmental benefits, like stormwater management; as well as financial benefits, like fewer construction errors.
“What we also learned in our research is these benefits are intertwined,” Mandel said. “So when you start to pull out these benefits, like efficient site management, what also gets pulled in is stormwater management and wildlife habitat.”
Alonso underscored a critical need for a continuous management within the site commissioning process to ensure performance and maintenance of the landscape. Project turnover is another instance where communication and management continuity are crucial.
Alonso said metrics the GSA gathers on projects “make the business case for landscapes we are building.”
Over a half of a million people in the United States are homeless. In major cities, homelessness is on the rise, due in part to increasing rent costs and a lack of affordable housing.
Officials and landscape architects addressing homelessness in Los Angeles, San Francisco, and Denver shared insights and lessons learned from their cities in a discussion at the ASLA Annual Meeting in Los Angeles. Panelists included Scott Gilmore, deputy executive director of Denver parks and planning; Joe Salaices, city of Los Angeles department of recreation and parks; and Guneet Anand, ASLA, SITELAB urban studio.
“You’re not going to end homeless,” Gilmore said. “There’s always been homelessness, and there will always be homelessness.”
“It can be a very daunting task,” he said about addressing the issue. “But I have hope. There are positive actions to be taken.”
Gilmore noted a series of initiatives in Denver, like the Denver Day Works program, which provides work experience in parks and public spaces for people experiencing homelessness. Gilmore says the program has been an effective recruitment tool for full-time employment with the city. The program also offers storage units for homeless individuals to keep their belongings while they access social or healthcare services.
“People think when you’re homeless you might be a drop out from high school or you don’t have everything together,” he said. “About 25 percent of these people are college educated. That gives you a sense that anybody in this room making the wrong step, or just having bad things happen, can be homeless at anytime.”
In Los Angeles County, homelessness jumped 23 percent last year. Salacies says that trend will likely continue, given the area’s expensive housing market. “We have situations where people become homeless because they miss a paycheck or two.”
Salaices said Los Angeles is working to collect data on the city’s homeless population.
“By collecting data we are able to go back and use it for budget services,” he said. “Without the numbers, the justification to share with elected officials, we’re never going to get the budget and money to improve our situation.”
In San Francisco, the leading cause of new homelessness is eviction. “Even though 44 percent of the homeless population does have a job they are not able to afford homes,” Guneet said.
She explained how SITELAB urban studio has been working with Lava Mae, which repurposes old buses into showers and toilets to serve homeless populations in San Francisco. Together, they developed the Lava Mae popup care village, which explores how the design of public space can better serve vulnerable populations.
“Care is the most important when you’re doing work that relates to the homeless, ” she said, adding that we are “sometimes desensitized because it is so present in our cities. We often walk past encampments and don’t think twice about what we can change or what we can do differently.”
Brie Hensold, ASLA, a principal at Sasaki and moderator of the session, noted a common thread between each of the cities is an effort to listen to the individuals and build relationship with the homeless communities, pointing to examples where “key individuals in the homeless population have become ambassadors and problem solvers.”
One such instance is found Gladys Park in Los Angeles, which has a large homeless population.
“A couple of the individuals started taking charge,” said Salaices. He added that the city has started hiring these people to help with maintaining spaces like the restrooms and grounds within the park.
“Principles of sustainability have to be at the center, not at the margins of design,” according filmmaker and eco-activist Shalini Kantayya, particularly in our era of dramatic population growth and resource scarcity. “Sustainability can no longer be a thing of the privilege, but something that is accessible to all sectors of society and the masses.”
Her films demonstrate the power of storytelling in inciting positive change. “The stories we tell as a culture have the power to shape the future,” Kantayya said.
She began with a clip from, A Drop of Life, her film about two women, on opposite sides of the world, and their access to water.
Kantayya used the film to underscore the fact that global potable water scarcity is an increasingly dire situation. Today, more than 2 billion people lack access to clean and safe drinking water, according to the World Health Organization.
“80 percent of illnesses in the developing world are due to water-related illnesses,” she said. “There are just no borders on this crisis.”
Kantayya pointed to the ongoing crisis in Puerto Rico where millions of American citizens are still without electricity, healthcare, and clean water a month after Hurricane Maria hit the island.
“This is a failure of a story. That somehow we have failed to frame this story as an American crisis, that this is happening to our fellow citizens,” she said.
In light of the lack of environmental leadership at the federal level, states, cities and communities can act to advance a more sustainable future.
Her film Catching the Sun is about the global transition to a clean energy economy. She tells stories of people working in the solar industry to illustrate the economic, social, and environmental impact of the movement.
Globally, the transition is moving rapidly ahead. China is the leader in solar with over 43 gigawatts of solar capacity, compared to the United States capacity of just over 27 gigawatts.
“You have seen China, in the last ten years, move from the factory of the world to the clean tech laboratory of the world,” she said, adding that the United States needs to better capitalize on this movement.
“What we need is smart policy, decisive leadership, and visionary landscape architecture that bring sustainable solutions into public spaces and to scale,” Kantayya said.
Over the past decade, the Los Angeles River has become a source of excitement, inspiration, and concern for residents, city officials, and planners and landscape architects as renewed attention is being paid to its revitalization.
At the ASLA 2017 Annual Meeting in Los Angeles, Barbara Romero, deputy mayor of city services for Los Angeles; Mia Lehrer, FASLA, founder and president of Studio-MLA; and Teresa Villegas, office of Los Angeles County supervisor Hilda L. Solis offered background on the river and planning and design efforts already underway.
Historically, the Los Angeles River, a 51-mile stretch of waterway, served as a vital water source for agriculture, but its constantly-changing course led to massive flooding that killed 115 people in 1938; and its unpredictability hindered development. By the 1930s, the Army Corps of Engineers began channelizing the river, encasing it in concrete.
As a result, today, “the river resembles a freeway more than a waterway,” said Frances Anderton, host of DnA and moderator of the panel.
The river is at the center of complex jurisdictional overlays, with a number of organizations and agencies, like the city of Los Angeles, the county department of public works, and the Army Corps of Engineers, to name a few, sharing responsibility over its maintenance and future plans.
Thirty-two miles of the river falls within the boundaries of the city of Los Angeles. Romero explained how the city is working to implement their 2007 master plan, focusing on reconnecting people, particularly in adjacent neighborhoods, to the river.
“The scale of this is enormous,” Romero said, underscoring the jurisdictional complexity of the revitalization efforts. Within the existing master plan there are 240 projects that incorporated community engagement, representing some $500 million in investment.
Romero pointed to the city’s collaboration with the Army Corps of Engineers to restore ecological function and public access to an 11-mile portion of the river. Within this segment is Taylor Yard, a 42-acre parcel, purchased in March from Union Pacific Railroad Company for $60 million. Work is underway with Studio-MLA and WSP to make it a public park, after cleaning up the contaminated brownfield site.
“If we’re really going to revitalize the river; if we’re really going to change the course of the river; if we’re really going to look at this ambitious plan, we needed to get this parcel into public ownership,” Romero said, referring to how acquiring Taylor Yard fit into the city’s revitalization plans.
Lehrer and her studio is designing public spaces in Taylor Yard, which is at mile 25, almost half way down the river.Her design studio is also situated on the river, and its revitalization has been a “passion project” of hers for three decades.
Lehrer said there is an opportunity to connect neighborhoods to the river while addressing environmental concerns like soil contamination and incorporating green infrastructure and creating new wildlife habitat. Lehrer also said there is an opportunity to use the river to create green infrastructure projects that recharge groundwater and get more water down into underlying aquifers.
“We think it’s good these 51-miles of infrastructure were kept away from any other kind of development. It has become an opportunity to bring the communities together to address environmental ills.” She added that “we want it to be resilient, inclusive, and an inspiration for Los Angeles.”
Villegas is coordinating revitalization efforts at the county scale. “We will be dusting off the old plan, opening it up, and adding to it,” she said, referring to the county’s master plan, which was last updated in 1996. They have created a stakeholder group of about 40 people.
The group is focused on the southern portion of the Los Angeles river. A park needs assessment completed last year showed a critical lack of access to green space. “We know we need additional park space in the lower Los Angeles River because it is densely populated.”
Revitalization efforts will coincide with the city’s preparation to host the 2028 summer Olympics. Romero said the major event can serve as a framework to invest resources. “This is not about bringing the world here for two weeks — it’s about reframing the discussion we want to have in our city,” she said.
While high-profile urban tree planting campaigns like New York City’s get a lot of attention, most U.S. cities have experienced a decline in their urban forests, with a loss of about 4 million trees each year, or about “1.3 percent of the total tree stock.” The Nature Conservancy builds the case for recommitting to expanding our urban canopies for health reasons, instead of just letting them slowly diminish.
The many benefits of trees are well-documented: they clean and cool the air, combat the urban heat island effect, capture stormwater, mitigate the risk of floods, boost water quality, and, importantly, improve our mental and physical health and well-being.
According to the report, the U.S. Forest Service and University of California, Davis found that “for every $1 spent in Californian cities on tree planting and maintenance, there were $5.82 in benefits.” Another study found that for every $1, benefits ranged from $1.37 to $3.09.
In particular, urban forests can help catch harmful particulate matter in their leaves and reduce “ground-level ozone concentrations by directly absorbing ozone and decreasing ozone formation.” High levels of particulate matter and ozone can trigger asthma and cause other respiratory problems. Planting trees to deal with these issues in New York City alone could result in $60 million in health benefits annually.
Researchers are more closely examining how trees fight air pollution. In Louisville, Kentucky, Green for Good is now testing a “vegetative buffer” at the St. Margaret Mary Elementary School designed to filter the particulate air pollution coming off a nearby heavily-trafficked roadway. Initial results show that “under certain conditions, level of particulate matter were 60 percent lower behind the buffer than in the open side of the front yard. Among the health study participants, immune system function increased and inflammation levels decreased after planting.”
A Harvard Nurses Study found a 12 percent reduction in all-cause mortality for those who lived within 250 meters of a high level of greenness. And an exciting study now underway will look at 4 million Kaiser Permanente members in Northern California with the goal of determining if there is a relationship between healthcare use and the proximity and amount of nearby tree canopy.
Despite all the great research, the news still hasn’t reached the general public or even arborists. This is reflected in the fact that average U.S. municipal spending on urban forestry has fallen by more than 25 percent since 1980, to around $5.83 per urbanite today.
If the 27 largest American cities instead reinvested in their urban forests, “planting in the sites with the greatest health benefits (the top 20 percent of all potentially plantable sites in a city)” the cost would be around $200 million a year. Maintenance funds would also need to increase. The total gap between current realities and this needed reinvestment in our communities’ health is only $8 per person — so in a city of one million residents, $8 million.
Trees just get a tiny share of municipal budgets. But with these arguments backed by numbers, the hope is a relatively cheap investment in trees for public health — which would also result in so many gains in livability and property values — can win greater support.
Green Roofs Are Getting a Big Trial in Hoboken– Next City, 8/18/17
“The movement toward green building and sustainability-minded development is at an odd crossroads. On one hand, some progressive cities have made regulation strides toward more energy-efficient and less environmentally harmful building practices, while a viable industry has grown up around green construction and roofing materials.”
