Rotterdam Redesigns Itself to Handle More Water

Port of Rotterdam, Wikipedia, Public Domain

Rotterdam in the Netherlands is the largest port in Europe. This 800-year-old city, which has a population of 630,000, is split into north and south sides by the River Nieuwe Maas. While the river is a major asset, it also increases vulnerability to climate change as sea levels rise. In a session at the ASLA 2018 Annual Meeting in Philadelphia, Dutch government officials, landscape architects, and planners discussed efforts to adapt Rotterdam and the rest of Holland to new realities.

After flooding in the early 1950s killed some 1,800 people, the Dutch were determined this would never happen again. According to Tim Van Der Staaij, a resilience officer with the Rotterdam city government, the country created a multi-layered system of “delta works” — a series of dikes, polders, and sluices to defend land against water. This system made Rotterdam, most of which is 6-7 meters below sea level, and its port possible.

But in recent years, climate change has made the intricate system that protects Rotterdam vulnerable. Van Der Staaij said the water management system has become “more unpredictable due to sea level rise, river discharge, groundwater rise, and excess rainfall.”

Given the city is already below sea level, Rotterdam has taken the approach that “we must accept the water; it’s better than fighting.” Once that conclusion was reached, city leaders saw an opportunity to redesign the city as part of a new Rotterdam resilience strategy, a set of “holistic, multi-level, multi-stakeholder” approaches.

In the past few years, the Dutch have invented new ways to “accept water,” including the water square by landscape architecture firm De Urbanisten, which is usually a public plaza with basketball court, but in extreme rain events becomes a temporary water storage space that “holds the water while the sewage system is over-taxed and then lets the water go later.”

Van Der Staaij said the city is now working on redesigning all public spaces to store water, including the new central station now in development. As part of this, Rotterdam has invested heavily in putting all that water to good use through its “water sensitive city” program, which invests in green roofs, tree planting, street-level gardens, and new green “tidal parks” along the river.

Han Dijk, an urban planner working with the city on its resilience plans, highlighted the tidal parks along the Nieuwe Maas — also to be designed by De Urbanisten — as central to creating a Rotterdam that can bounce back from repeated flooding. “The city will build new land with fill, soften the river’s coasts, and open up and connect islands.”

And Gerda Roeleveld, a landscape architect with Deltares, a independent research institute, explained how the Netherlands has invested in 3D simulated models to help local policymakers, planners, and designers — as well as the general public — understand the potential impacts of climate change.

She showed off some sophisticated animations that visualize climate impacts, including the distribution of water — from the national to the site-levels. A set of these adaptation support tools, based in real-time data, are supporting Dutch communities in their efforts to devise new climate resilience and adaptation strategies, which they obligated to create by 2019.

Landscape Architects: Now Is the Time for Climate Action

Climate Positive Design / Pamela Conrad, ASLA, CMG Landscape Architecture

Earlier this month, the United Nations Intergovernmental Panel on Climate Change (IPCC) released a bombshell report concluding that the world has as little as twelve years to act to stave off the worst impacts from a warming climate.

Despite the weight of that assessment, a panel on climate action and landscape architecture at the ASLA 2018 Annual Meeting in Philadelphia gave reasons to be hopeful and presented new tools that may help landscape architects reduce their climate impact.

“The next few years are probably the most important in our history,” said Pamela Conrad, ASLA, a senior associate at CMG Landscape Architecture. “We believe our profession can be part of the solution, and that it’s time to work together.”

ASLA past-president Vaughn Rinner, FASLA, enumerated the many climate-focused initiatives ASLA has undertaken in recent years, including the ASLA Center Green Roof, the Chinatown Green Street, advocacy efforts, online resource guides, collaboration with federal agencies to develop resources and toolkits, and the recently convened Blue Ribbon Panel on Climate Change and Resilience and its report: Smart Policies for a Changing Climate.

Rinner stressed the need for landscape architects to become more involved with discussions around public policy. “We all have to advocate–that’s the first step,” she said. “If we can’t change policies, so many things will just continue as is.”

Collen Mercer Clarke, chair of the Canadian Society of Landscape Architects (CSLA) committee on climate adaptation, gave an overview of CSLA’s efforts, which include the creation of a series of primers on climate adaptation and the promulgation of design standards that were written taking climate change into account.

Clarke urged the audience to think globally. “The world is waiting. I haven’t seen another profession that can provide the kind of leadership we can on this issue.”

Martha Schwartz, FASLA, CEO of Martha Schwartz Partners, highlighted recent work by the Landscape Architecture Foundation (LAF) in the spirit of the organization’s 1966 Declaration of Concern. In 2016, fifty years after that initial declaration, the LAF convened to draft the New Landscape Declaration, which places climate change at the center of the profession’s focus for the 21st century.

“After centuries of mistakenly believing we could exploit nature without consequence, we have now entered an age of extreme climate change marked by rising seas, resource depletion, desertification, and unprecedented rates of species extinction,” the statement reads.

“The urgent challenge before us is to redesign our communities in the context of their bio-regional landscapes enabling them to adapt to climate change and mitigate its root causes.”

Earlier this month, LAF released a ten-point plan for landscape architects to act on this declaration. Action items include: designing with nature, setting measurable goals for climate-performance metrics, leading by example, developing interdisciplinary partnerships, serving in community organizations, and voting.

“We’ve got to be tougher and better at doing this,” Schwartz said. “It’s not enough to be a good designer, but an active designer, to take leadership in the era of climate change and stay relevant in an ever changing world.”

LAF is also supporting leadership on climate change through its fellowship program, which began in 2017 and provides funding for active professionals to pursue innovative research ideas. As an LAF Fellow, Pamela Conrad has developed a calculator that predicts the emissions and carbon sequestration potential

“A few years back, I assumed I could go online and download a tool that would tell me exactly what I wanted to know. But frankly, those tools really only exist for architects right now. Because we have the ability to sequester carbon, perhaps we need our own tools to measure these impacts.”

Landscape Carbon Calculator / Pamela Conrad, CMG Landscape Architecture

Conrad’s tool, which is still in beta testing and has not yet been publicly released, measures sources of embodied emissions in landscape materials against the sequestration potential of vegetation on a site to calculate both the carbon footprint of a project and the amount of time it will take for sequestration to completely offset emissions. Past that point, the project will  sequester additional atmospheric carbon dioxide, a condition Conrad calls being “climate positive.”

Climate Positive Design / Pamela Conrad, CMG Landscape Architecture

Using the calculator, Conrad has been able to estimate the carbon footprints of her recently completed projects and, by tweaking the input parameters, model strategies that could have reduced their climate impacts.

“We can plant more trees and woody shrubs; we can minimize paving, especially concrete; we can minimize lawn areas; we can use local or natural recycled materials.” With these strategies, Conrad estimates that she could have cut the time it will take for her projects to become carbon neutral in half.

“The design of those projects didn’t change at all, or the quality for that matter. But what a difference it could have made if we just had the resources to inform our design decisions.”

Carbon Positive Design / CMG Landscape Architecture

Conrad argued that, through climate sensitive design, landscape architects could be responsible for the sequestration of as much as 0.24 gigatons of carbon over the next thirty years, enough to place landscape architecture in the list of 80 solutions to climate change studied in Paul Hawken’s Drawdown project.

And “if we were to include other work we do, like incorporating green roofs into projects or making cities more walkable and bikeable, that would put landscape architecture within the top 40 solutions.”

Conrad plans to release the calculator to the public next year and hopes that it will be used to set measurable goals for designing climate-friendly projects and create opportunities for accountability.

“How are we going to keep tabs on ourselves to make sure that we’re actually doing these things?” she asked her fellow panelists. “What would it take for us to have a 2030 challenge specific to landscape architecture?”

“ASLA or the LAF should do that — there’s no reason why we can’t!” said Schwartz.

“We all have to stand up for what this profession is founded on,” Schwartz said. “This is the foundation of who we are. This century is the golden age of landscape architecture. The world really needs you. It needs what you know and what you believe in. Now is the time.”

Iceland Blends Renewable Energy into the Landscape

Icelandic landscape / Landsvirkjun

Iceland, a land of glaciers and volcanos found directly over the Mid-Atlantic ridge, is entirely powered by renewable energy. More than 70 percent of the country’s energy comes from hydro power, while the rest is from geothermal sources — the incredible heat found just below the surface caused by red-hot subterranean lava fields. As the millions of tourists who visit each year cause the country’s power needs to grow, Iceland is expanding its geothermal systems. In the face of intense public protests that these systems are marring the stunning landscape — not to mention the usual Not-In-My-Backyard (NIBMY) complaints — Landsvirkjun, the national power company of Iceland, created a new landscape policy designed to create a more harmonious relationship between land and energy. And landscape architect Björk Guðmundsdóttir took the initiative to make this all happen.

At the ASLA 2018 Annual Meeting in Philadelphia, Guðmundsdóttir explained that when she started her multi-year effort, there wasn’t a single design guideline for renewable energy projects. Her task was to create a new national landscape policy for these systems, while being the only women — and landscape architect — working with a team of all-male engineers.

Her first step was to understand the geothermal energy system development process, the legal frameworks that shape energy production, and the broader energy policies. One important high-level Icelandic policy guided her work: energy systems “should operate in harmony with the landscape.”

She spent time finding the gaps in the renewable power plant operations that were “open to the influence of design.” Establishing a working group within Landsvirkjun, she ended up creating a process that brings design into every stage of the renewable energy project development process — from the early environmental and visual impact assessments to the design concept, detailed landscape plans, and maintenance approach.

Guðmundsdóttir said creating design guidelines required thinking through all the ways how development touches the landscape. For example, “do you require buildings to be white so they blend in with the snow that covers Iceland for much of the year? Or instead should they be a neutral color so they blend with the summer landscape, when there are the most numbers of tourists?”

Landsvirkjun eventually settled on a series of design guidelines — seemingly simple but with a positive impact on new projects — that also create new roles for landscape architects. Guidelines include: create projects in harmony with their surrounding landscape, including careful site selection to minimize impact and roads that follow the topography. Minimize cut and fills. Re-vegetate, re-forest, and restore the landscape. Re-use all natural surface materials. Orient pipelines, which must be on the surface due to the extreme heat found in some places just a few feet below the surface, so they blend in as much as possible. And design every power-related building to be multi-use.

Aðalheiður Atladóttir, with A2F Architects, showed how the new landscape policy is shaping their work on a geothermal power station — Hagonguvirkjun, near Hagongulon Lake in the center of the country — and associated worker housing and hotel.

A2F created a power plant with a warm, inviting restaurant and visitor center — its entire form mimics the glacier and mountain ranges in the background.

Hagonguvirkjun / Landsvirkjun, A2Architects

And nearby there is a building that is both housing for the plant workers and a hotel that features a spa and greenhouse — a “nice place to chill.” The team will build gabion walls from stones collected nearby, so the “building looks like it grew out of the landscape.”

Hagonguvirkjun / Landsvirkjun, A2Architects

To bring in some fresh thinking and expand the conversation with her engineer colleagues, Guðmundsdóttir partnered with SUNY Syracuse landscape architecture professor Matthew Potteiger and his graduate students, who spent a semester studying in Iceland. The Americans completed a two-week planning and conceptual design charette with Landvirkjun in the very-hot landscapes of Krafta in northern Iceland, where both the first geothermal power plants and the newest are found. The goal was to create a new interpretation system for a geothermal power plant for Icelanders and tourists.

Potteiger said interpreting the “landscape of geothermal power” was challenging because the unique geophysical forces at work under the ground and the surface engineering systems are equally enigmatic. Plus, there are sheep, who strangely only hang out in groups of three, randomly grazing amid all the “industrial sublime.”

Exploring the site and all its sensory experiences, Potteiger and his students proposed some inventive, small ways design can enhance the visitor experience. For example, plumes from the geothermal vents can be used to create “steam paths that act as a wayfinding device.” Once a geothermal well has gone cold and its equipment is removed, the original soil, stones, and vegetation could be returned to the site, which would create a marker revealed through stages of vegetative growth. And sheep, which are “heat-seeking devices who love to cuddle in winter,” could be given designed social spaces, protective structures along pipelines, so they can cuddle in style.

To Limit Global Warming, We Must Transform the Planet

To limit planetary warming to 1.5° Celsius (C), we need to undertake an immediate, multi-trillion-dollar transformation of global energy, land-use, food production, transportation, and urban systems, stated the Intergovernmental Panel on Climate Change (IPCC) in a new report that aggregates the findings of thousands of scientific studies. Humanity can only put a maximum of 420 more gigatons of greenhouse gas emissions into the atmosphere if we want a good chance of only increasing temperatures by 1.5° C (2.7° Fahrenheit), instead of 2° C (3.6° Fahrenheit). At the current pace, our remaining carbon budget will be used up by 2030. The transformation that has already begun in many parts of the world must accelerate and scale across the globe.

To date, global temperatures have increased 1° C (1.8° F) above pre-industrial levels. The IPCC argues that limiting warming to just another half a degree Celsius will still have terrible global impacts, but stave off some of the worst effects and make a major difference for several hundred million people.

Achieving the 1.5° C limit can only happen in the very near term. IPCC states if the planet can achieve net-zero emissions in the coming decades that would essentially halt warming. But if emissions reductions instead occur at a much slower pace up until 2100, then planetary feedback loops — like defrosting permafrost perpetuating warming trends — would make halting warming at 1.5° C impossible.

There are significant differences between 1.5° C and 2° C increases. A 1.5° C temperature increase would mean about 4 inches less of sea level rise by 2100, and at a much slower rate of rise. This would buy time to help the hundreds of million of people who live on coasts and deltas to adapt their infrastructure with resilient natural systems that can also restore and bolster important coastal habitats.

With a 1.5° C increase, some 6 percent of insects, 8 percent of plants, and 4 percent of vertebrates are projected to “lose over half of the climatically-determined geographic range” — meaning their habitat will disappear. While this is awful, the scenario at 2° C increase is far worse: 18 percent of insects, 16 percent of plants, and 8 percent of vertebrates. Impacts from forest fires and invasive species would also be commensurably more at 2° C.

The chance of an ice-free Arctic Ocean during summer is far less with a 1.5° C scenario. But coral reefs face a dire future under both 1.5° C and 2° C scenarios: either a 70-90 percent loss with 1.5° C or near-total extinction with 2° C.

Climate change is also expected to have major impacts on food production, resulting in reduced yields and less nutritious crops. Limiting warming to just 1.5° C would result in “smaller reductions in yields of maize, rice, wheat, and other cereal crops, particularly in Sub-Saharan Africa, Southeast Asia, and Center and South America.” The report authors are also semi-confident that limiting warming to 1.5° C would also reduce the populations affected by water shortages by 50 percent. Still, millions of people would be impacted.

The IPCC report outlines potential pathways to zero carbon. Essentially, greenhouse gas emissions must drop by 45 percent by 2030 and 100 percent by 2050. This would require “rapid and far-reaching transitions in energy, land, urban, and infrastructure (including transport and buildings), and industrial systems.”

IPCC admit that the changes are unprecedented in terms of scale — but not speed. Previous economic and social transformations have occurred with a few years; think of the US economic transformation during World War II or the appearance of smartphone apps in 2007 and their widespread application today.

The report estimates the damage of a 1.5° C increase to the global economy to be tens of trillions a year as soon as 2040. To avoid this, major investments must be made. The report calls for investing $2.4 trillion a year on renewable energy through 2035, which would be about 2.5 percent of global GDP annually, while weaning off coal. The planet would also need another 10 million square kilometers in forests, taken back from agricultural land, and a dramatic reduction in emissions from buildings and transportation systems through energy efficiency and smart growth.

A recent analysis conducted as part of Drawdown, a publication that ranks the 80 most effective ways to reduce greenhouse gas emissions, yielded solutions where landscape architects and planners can help accelerate the transformation. These include: afforestation (#15); mass transit (#37); water savings at home (#46); restoring and protecting coastal wetlands (#52); walkable cities (#54); bike infrastructure (#59); and green roofs (#73). There are also some landscape architects involved in siting renewable energy infrastructure, restoring farm land, managing forests and peatlands, which all rank highly.

IPCC is confident this global transformation can occur. If a mix of adaptation and mitigation measures can be “implemented in a participatory and integrated manner,” they can enable a “rapid systemic transition.” Adaptation measures don’t have to be purely defensive — they can also help communities improve, ensuring “food and water security, reducing disaster risks, improving health conditions, maintaining ecosystem services, and reducing poverty and inequality.” Now, the political will is needed to act.

Parks Are a Critical Solution to Climate Change

Parks boost community resilience because they offer a place to develop deeper neighborhood connections. They improve community health by reducing stress, restoring cognition, and providing a place to exercise. Parks mitigate the urban heat island effect, improve air quality, and absorb carbon from the atmosphere. They support local biodiversity and can act as buffer zones for flooding or mudslides. Parks are both important social and environmental infrastructure.

To sum it up: “we need more parks if we want our cities to be more resilient to climate change,” said Joshua Alpert, director of special projects for C40, at an event organized by The Trust for Public Land and JBP Foundation during the Global Climate Action Summit in San Francisco.

“We need public space if we want to know our neighbors,” explained Joshua Stanbro, with the city and county of Honolulu, Hawaii. Parks are the “platform for social interaction,” but if designed and built with the community, they can also help forge stronger community connections.

Those connections are more likely to happen in parks that communities actually want. So it’s important that “we meet communities where they are,” said Diane Regas, president and CEO of The Trust for Public Land.

In New York alone, The Trust just built their 200th green schoolyard in an effort to build social networks so these communities can then better fight for climate equity.

Regas said some one-third of the population of the US doesn’t have a park within a 10-minute walk. Through their innovative 10-minute walk campaign, The Trust and its partners aim to undo that inequity.

Brady Walkinshaw, CEO of Grist, said the campaign is the kind of clear, simple communication that is needed because it successfully distilled complex urban planning ideas into an easy-to-understand message people can get behind, like the $15-an-hour minimum wage movement.

Urban parks are also important because they provide the foundation of urban forests, which help cities both mitigate carbon emissions and adapt to a changing climate. According to Jad Daley, CEO of American Forests, urban forests absorb some 100 million tons of carbon each year, about 2 percent of global greenhouse gas emissions. Trees found in these green areas can reduce energy use up to 7 percent because they provide wind blocks for homes in the winter and cooling in the summer.

In an effort to achieve equity, American Forests is now working with vulnerable urban populations to plant millions of trees. Daley said this work is more critical than ever because deaths from extreme heat are expected to increase ten fold by 2050.

Arturo Garcia-Costas, program officer for the environment with the New York Community Trust, said a more connective approach needs to be taken with green spaces in cities. He pointed to the Ramblas in Barcelona and the High Line in New York City as examples. “We need to think of the broader system and greater connectivity, with green space as the priority.”

Ramblas, Barcelona / Wikipedia, Ralf Roletschek, GFDL 1.2

Nancy Somerville, Hon. ASLA, CEO of the American Society of Landscape Architects (ASLA), said ubiquitous “pave the planet” approach to development hasn’t been “healthy or climate-smart.” In fact, the approach make communities even more vulnerable to the impacts of climate change. To increase safety, communities must instead create built environment systems that work in concert with natural systems. This is because “we are never going to tame Mother Nature.”

As an example, she said there is a great opportunity to design parks — and cities more broadly — to act like natural sponges that absorb stormwater. The great additional benefit of this green infrastructural approach: “It’s a much healthier system.”

But Somerville also called for better science and data-based models in order to optimize design interventions in cities. With more accurate data-based geographic models and maps, policymakers can understand where the worst urban heat islands are, the most flooding is, the areas most impacted by mudslides, and then create the most effective parks that solve those challenges. “The lack of modelling remains a key gap.”

In comments on the session, landscape architect Mia Lehrer, FASLA, CEO of Studio-MLA, noted that in dense cities, the only remaining spaces that can be turned into parks are brownfields. Remaking those contaminated spaces is a “complicated and expensive process” that requires expert landscape architects.

Adrian Benepe, Hon. ASLA, senior vice president at The Trust for Public Land and former head of NYC Parks and Recreation, agreed, arguing that “landscape architects are system thinkers” who can help communities maximize park benefits.

Lehrer, Alpert, Somerville, and Walkinshaw saw further densification as a critical future challenge for cities. Walkinshaw said: “densification is the cause of most fights in cities, as it brings up racial, civil rights, public space, and climate issues.”

Alpert believes green public space in the ultra-dense mega-cities of the near-future may end up being dis-aggregated into networks of not only parks but also rooftops and terraces, wherever space is available.

Designing for the Other Four Senses

The Senses: Design Beyond Vision / Princeton Architectural Press

The Senses: Design Beyond Vision, a new book from designers and curators Ellen Lupton and Andrea Lipps, is a compelling survey of the emerging field of sensory design. The book accompanies an interactive exhibit of the same name by the authors on display at the Cooper Hewitt Design Museum through October 28th. While The Senses is not quite the manifesto for multi-sensory design practice its authors claim it to be, the book captures the poetics and science of sensory design and in doing so conveys some useful lessons for landscape architects.

Sensory design’s historically-narrow application has broadened as our own understanding of the senses has gained sophistication. Add to that the potential of emerging technologies to create and augment sensory experiences, along with the urgent need for more inclusive design, and you have the swell in popular attention the field is currently experiencing.

It’s worthwhile to ask whether, as landscape architects, we are guilty of treating hearing, taste, scent, and touch as second-class senses. Put to any landscape architect that the senses other than sight are important and you’re likely get a nod of agreement. What isn’t as clear is whether this acknowledgment commonly manifests in our design work.

Sensory experience commands greater consideration in landscape architecture than most design fields, and so landscape architects are better attuned to their designs’ effect on the senses. But we often conceive of and deploy landscape architecture as a palliative to harsher environments than rich sensory environments in and of themselves. As to how we might improve and innovate in this regard, The Senses offers some inspiration.

The first step is to bring to sensory design the same level of critical thought brought to visual and spatial design. What are the qualities of an environment where all five senses have been weighted equally in the design process, not simply manufactured under “the tyranny of the eye”?

The Senses features an interesting case study in San Francisco’s LightHouse for the Blind and Visually impaired. There, light and space are maximized, materials are chosen for their acoustic properties over their appearance, and details such as tapered handrails and textured steps are integral elements, not tacked-on details.

One recurring practice among The Senses’ featured designers that has an application for landscape is layering. Layering allows for the creation of environments rich with hierarchy and nuance.

Snarkitecture’s undulating wallpaper, Topographies, is one example, as is the Rich Willing Brilliant Studio’s attitude towards lighting. According to these designers, sound, smell, light, flavors, and texture can be layered to form thresholds and barriers, ceilings and corridors. If this seems architectural, that’s intentional. Perfumer Christophe Laudamiel stresses the multi-dimensional quality scents take on when layered and allowed to develop volume. Laudamiel is a master of evoking landscapes with his scents, such as meadows dense with wildflowers and the Bosporus Strait.

If there’s one project in the book the offers a more grounded idea of how landscape architecture and sensory design can interface, it is Tactile City. Expanding on existing tactile paving systems, Tactile City illustrates how streetscapes can be designed to benefit the visually impaired. Highly-textured paving tiles can signal features of the environment to someone relying on a walking stick. Indications of street furniture, bus stops, or construction can be imprinted in the landscape. “Sensory design can shape the beauty and function of a place – and address dangers and obstacles,” the authors write.

Much of the exhibition and book is concerned with new technologies: The Scent Player, emitting smells instead of music,  or a device that converts reverberations against the skin into dialogue for the deaf. These technologies, while not immediately translatable to landscape architecture, underscore the fluid nature of our senses. The authors do an excellent job of conveying how senses feed and play off of one another. Sights can trigger smells can trigger tastes, with past experience setting some of the rules for these exchanges.

Scent Player, Cyrano, 2017 / Photo by Wayne Earl Chinnock. The Senses: Design Beyond Vision (c)2018 Princeton Architectural Press

Experience of the landscape should engage all of our senses. Sensory design is about maximizing that experience and making sure others of differing abilities can as well. The Senses is a worthwhile read for landscape architects wanting to pursue these goals.

Charles-Joseph Minard: A Legacy of Beautiful Data-based Maps

The Minard System: The Complete Statistical Graphics of Charles-Joseph Minard / Princeton Architectural Press

Edward Tufte, the world’s best known information designer, said Charles-Joseph Minard’s statistical map of Napolean’s 1812 invasion and then retreat from Russia was the greatest information graphic ever made.

In a delightful new book, The Minard System: The Complete Statistical Graphics of Charles-Joseph Minard, author Sandra Rendgen uncovers the man who made the graphic as well as his many data visualization innovations.

Born in Dijon, France in 1871, Minard spent his career as a civil engineer, with much of it as an inspector of transportation infrastructure. It’s only in retirement that he was able to delve into his passion for the visual representations of statistics.

Minard’s engineering education and career deeply informed his approach to statistical maps. He had a “general appreciation of fact-based scientific practice, which tends to value empirical evidence over abstract reasoning and intuition.” His graphics were driven by the desire to best enable the “systematic gathering and evaluation of facts.”

But for a man so interested in scientific precision, there is also real beauty to his visualizations, with their “clean and minimalist aesthetics.” Rendgen argues that experts know a Minard visualization when they see one: “Not only are they refined in every detail of their rendering, including the lines, the dotting, the hachure, and the concise labeling, they also have a very ‘modern’ appeal to them.” He was then not only a engineer and statistician but also a designer.

Before Facebook created the Like button, Minard perfected a number of essential and elegant infographic elements that are now core to our global visual vocabulary.

For example, starting in 1845, Minard perfected the use of proportional circles on maps to indicate the amount of certain goods or populations in any given place.

Minard is also know for his simplistic yet also precise “flow maps” that indicate overall traffic volumes of goods or people over territories. Minard expected his detail-minded viewers to carefully examine his maps, perhaps even with a ruler, so he drew the flow intervals or widths to be exact to the millimeter. For example, in the graphic below, Minard visualized the tremendous decline in cotton imports (the blue band) from the U.S. to Europe during the American Civil War to the tons.

The flow maps had to be both accurate and easy-to-understand: they were designed to help traffic engineers “predict demand on existing or projected routes,” or policymakers understand the bigger picture and make necessary policy, tax, or regulatory changes.

As Minard honed his craft over the years, Rendgen says his work only improved. “He gradually developed an understanding of the intricacies of integrating many different flows into one coherent representation and continually worked on avoiding clutter in his multi-flow representations.”

During his lifetime, Minard’s visual innovations were immediately and widely copied because they were so intuitive. His legacy is found in nearly every data visualization we see today. And the Minard system is perhaps needed more than ever before — to wade through the ever-growing sea of data and see clearly what it all means.

Glenstone Slows You Down

Emily and Mitchell Rales, the founders of Glenstone, one of the largest privately-owned museums in the U.S., want you to slow down.

As you get out of the car park at their expanded museum in Potomac, Maryland, you embark on a 10-minute journey along a gravel path, over a small creek, and between two large hills. Walking the path becomes an act of meditation, but also a journey of discovery as you come across surreal bits of hyper-nature.

After a few minutes the new pavilions designed by architect Thomas Phifer emerge into view.

The crunch of the pale grey gravel, the charismatic trees set in swaying meadow grasses — mostly little blue stem and purple top — are all designed to slow your heart rate and heighten your senses.

At the preview of the expanded museum, which is set within a 230-acre landscape, Emily Rales explained that it’s only when you are most attuned to your environment can you really take in the post-World War II artworks in their monumental new concrete pavilions.

Visitors descend stairs or an elevator to get to the main level of the pavilions where most of the modern and contemporary paintings and sculptures are found.

Pieces include a phrygian cap by African American sculptor Martin Puryear, a calendar of icons by Lygia Pape, an expansive Rothko painting, and epic site-specific installations by land artist Michael Heizer.

Collapse, one of Heizer’s works, called for the special configuration of an entire wing. Only six people are allowed to experience the piece at the same time — a 16-feet-deep hole partially filled up with rusted steel beams, set in a small ocean of rust-colored gravel, which creates a Martian monochromatic landscape.

But the building is not only a portal to the art, it’s an entry into a whole other landscape: a water garden.

Adam Greenspan, ASLA, principal at PWP Landscape Architecture, who has been working on Glenstone for the past 15 years, said the “center pool is the culminating moment.”

The entire landscape has prepared you for this. “We designed the site as a holistic experience — from the region to the site. We knitted it all together.”

The landscape that leads you to the building was molded from the soils dug up to make way for the pavilions. Hundreds of tons of soil were sculpted into hills. Some 8,000 trees were planted. There are now 40 acres of meadows within the sweeping estate. The early agricultural landscape has been transformed.

There is an underlying Japanese influence to the landscape and architectural design with the use of minimal gestures for maximum impact. Greenspan said the water garden is really “Ryoan-ji a couple of steps removed.” (Ryoan-Ji is one of the most famous Zen Buddhist gardens in Kyoto). The water garden itself is partially inspired by an Iris garden found in Hakone. “It’s similar in scale and size.”

However, the water courtyard at Glenstone also differs in some notable ways from its Japanese inspirations. PWP Landscape Architecture put the plants on a grid, which provides an underlying geometrical depth to the space. They did this for not only aesthetic reasons but also for practical ones.

The squares found within the grid enable the landscape architects to create areas of different soil depths, so they can contain and define the different plant life. “Irises need 4 inches of water or less; pickerelweed needs 8-10 inches; but water lilies need 8 feet of water.” Each get their own squares.

Within the modular approach, plants can also easily be re-arranged depending on how well they are doing in one micro-climate or another. “We have a living system that can move.”

Up and out amid the hills again, you may notice that meadow grasses seamlessly extend into a green roof that covers part of the buildings. And that the glass banisters purposefully minimize the difference between building and landscape.

Beyond these banisters, you come across an awing site-specific work by Heizer, called Compression Line, opposing ditches set in his rust-metal gravel.

Trails off the main building take you to large works by Richard Sierra, Jeff Koons, and Tony Smith, as well as the first part of Rales’ museum, which opened across a pond from their home in 2006.

Atop of a hill on one of those trails, an arching Sierra entitled Contour 290 looms and then storms into full view. A matted-grass and dirt path takes you to right up to the piece, creating a journey to a more elemental realm.

As you spend more time at Glenstone, you may think the art, building, and landscape must be explored again in a different season or sky. Emily Rales’ call for deeper awareness lingers: “we want you to notice the changing light.”
