Sea level rise is coming, and its impacts will be far reaching. For the state of California, the threat of sea level rise may prove existential. More than two-thirds of its population lives in the states’ 21 coastal counties, which are responsible for 85 percent of the state’s GDP.
However, sea level rise will not just impact human activity. Rising tides will also drastically alter, and in some cases destroy, important coastal habitats. Conserving California’s Coastal Habitats, a new report from The Nature Conservancy, provides a startling analysis of the future of California’s coast and charts a path forward for coastal conservation efforts.
The California coast represents the most biodiverse region in the country’s most biodiverse state, lending nationwide significance to coastal conservation efforts there. “The state of California has been a leader in environmental policy for over a century,” say the report’s authors, praising the state’s “legacy of coastal conservation.”
However, current policy and decision-making frameworks have been “developed to reflect static existing conditions and are not well suited for the dynamic needs of adapting to sea level rise,” the authors warn.
At risk are “nesting areas along global migrations for diversity of species, as well as nesting and pupping habitat, nursery habitat, and important feeding grounds critical to populations of many species, some which are found nowhere else in the world.”
Sea level rise threatens areas of human settlement and activity, too. The conversion of land to tidal and subtidal coastline will reduce the size of natural buffers, providing less protection to human settlements in coastal flooding events. Saltwater intrusion will impact agriculture. According to the Conservancy, sea level rise and the flooding this will cause could damage or destroy nearly $100 billion worth of property along the California coast by 2100.
The report’s authors used GIS to identify and map the coastal habitats, ecosystems, and infrastructure most at risk from sea level rise. They based their projections on two and five feet of sea level rise, which they say are in keeping with projections issued by the California Coastal Commission. The authors then developed metrics to measure the potential impact of sea level rise on a given area and the area’s vulnerability and ability to adapt.
Their findings are worrying. “As much as 25 percent of the existing public conservation lands within the analytic zone will be lost to subtidal waters,” they warn. Habitats for eight imperiled species will be completely inundated. Large portions of other significant coastal habitats are “highly vulnerable,” including 58 percent of rocky intertidal habitats, 60 percent of upper beaches, and 58 percent of regularly-flooded estuarine marshes. “At least half of the documented haul-outs for Pacific harbor seals and Northern elephant seals, and nesting habitats for focal shorebirds like black oystercatchers, are also highly vulnerable.”
Maps show that habitats in the San Francisco Bay Area are particularly at risk. There, vulnerable landscapes and habitats–such as 87 percent of the state’s regularly-flooded estuarine marsh–will be trapped between rising seas on one side and human development on the other. “The built environment–including roads and other infrastructure–creates barriers that prevent coastal habitats from moving inland,” while “dikes, levees, and other water control features negatively impact the health and function” of these threatened landscapes.
The Conservancy finds that sea level rise could adversely affect public access to California’s coast. “Sea level rise will diminish coastal access opportunities throughout the state by reducing beach widths, submerging rocky intertidal areas, and flooding coastal beach infrastructure.”
In the face of these potentially-devastating impacts, the report presents a suite of strategies for conservation in the era of climate change. Habitat managers need to “conserve and manage for resilience.” This includes maintaining the conservation status of existing conserved lands and identifying and protecting resilient coastal landscapes that are not vulnerable to sea level rise.
The Nature Conservancy recommends managing for resilience through the use of sediment augmentation and sand placement. “The majority of highly vulnerable conservation lands in need of managing in place for resilience are found in the San Francisco Bay Delta,” an observation that speaks to the importance of landscape-led initiatives such as the recent Resilient by Design Bay Area Challenge.
The Conservancy also calls for conserving nearly 200 square kilometers of potential future habitat areas and adapting the built environment “with more natural coastal processes in mind” – in effect, giving the coastline room to change.
“As sea levels rise, California’s coast will erode and evolve, and habitats will need to shift. Our current conservation efforts and land use management decisions must focus on further supporting these natural processes and enabling the transition and movement of coastal habitats as sea levels rise. Conservation in the face of sea level rise requires an adaptive process that embraces the reality of a dynamic coastline.”
The reports’ recommendations and strategies are “spatially explicit,” with specific proposals for areas, depending on their vulnerability and adaptive capacity. There are detailed high-resolution maps that illustrate the location, distribution, and severity of risks as well as opportunities.
“The results of this spatially explicit assessment provide a foundation of information to support immediate action to conserve habitats and biodiversity in the face of sea level rise,” the Conservancy argues. “With so much of California’s coastal habitats, imperiled species, and managed lands at risk from sea level rise, immediate collective action is necessary to conserve these natural resources into the future.”
As we look forward to covering new stories on the built and natural environments this year, here’s a look back at the 10 most popular DIRT posts of 2018. Readers were most interested in the debate over whether beauty still matters in an age dominated by science; how the practice of landscape architecture is evolving to deal with climate change and increasingly diverse communities; how urban sprawl is impacting biodiversity; and the interesting relationship between landscape architecture and retail. As in past years, new research on the health benefits of nature remains a favorite topic.
Always worth mentioning: We are looking for original op-eds, particularly from member landscape architects, designers, and planners, on topics that inspire you. And tell us about your new projects and research. Please email us at firstname.lastname@example.org.
Kicking off a two-day planting symposium at the University of California at Berkeley, professor emeritus Marc Treib posed the question: Is there still a place for the “art of landscape design” in an age “dominated by the science of landscape ecology?” Planting design is often brushed aside as superfluous or unserious. British historian and critic Tim Richardson reminded the audience of the litany of unfavorable adjectives associated with artful planting: the bourgeois, the small-scale, the amateur, the hobbyist, the ephemeral, the female.
If you are looking for a unique book to give as a gift or just one for yourself to delve into over the winter break, explore THE DIRT’s top 10 books of 2018, our picks for the best on the environment, cities, and landscape.
Instead of simply responding to catastrophe, Boston is getting out front on climate change. As part of its Climate Ready Boston plan, the city of 670,000 aims to act fast and protect two coastal neighborhoods most vulnerable to rising sea levels and storms: East Boston and Charlestown. New plans for these neighborhoods explain how a simple fix like creating a temporary flood wall at the coastal end of the East Boston Greenway, at a cost of just $100,000, would protect 4,300 residents, 70 businesses and critical infrastructure, and result in $17 million in benefits.
When a neighborhood floods, who is at fault? A class action lawsuit in Houston asks that question. The residents of a master-planned community that flooded during Hurricane Harvey are suing the engineering firm that designed the neighborhood’s stormwater management system. While that suit targets engineers, it nonetheless represents the heightened risk landscape architects face from climate impacts on their projects.
Cities are sitting on a largely underused public resource: urban stormwater wetlands. If properly designed, these landscapes can reduce flooding, support urban wildlife, and serve as public space. A new report Design Guidelines for Urban Stormwater Wetlands — authored by an interdisciplinary group of researchers and students at the MIT Norman B. Leventhal Center for Advanced Urbanism led by Celina Balderas Guzmán, Heidi Nepf, and Alan Berger — advocates for the positive role wetlands can play in cities and outlines research that provides insights for landscape architects, engineers, and planners.
Neurosurgeon Edie Zusman, a real-life Doogie Howser who started medical school at 19 and has completed some 6,000 brain and spinal surgeries, said what landscape architects do saves far more lives than what she does. The early prevention of disease reduces the need for surgeries. Prevention is made possible by eating healthy foods and walking and getting exercise in green environments that lower stress and improve well-being.
Trees are really essential for a competitive shopping district. There was a study by Kathleen Wolfe that indicated trees increase price elasticity by 9-12 percent. In other words, people feel comfortable paying up to twelve percent more for the same product if they purchase in a well-landscaped place with nice streets. Also, when properly located, street trees keep people in the downtown district longer. They feel more relaxed and are more likely to spend more money.
Participatory design is “hands-on democracy in action,” argue the editors of the impressive new book Design as Democracy: Techniques for Collective Creativity. Participatory design (also known as cooperative or co-design) is a process in which a designer actively involves all stakeholders in a design process. Unfortunately, many of the best-known techniques to enable this approach, which have been used for the past few decades, have become stale. This has led to complacency among designers, and less-than-ideal outcomes for communities that need their help. To revitalize the approach and achieve better results, the authors call for making participatory design “truly democratic.” Furthermore, it must become “contextual, open, experiential, substantive, and holistic.”
We experience “soft fascination” with nature when we sit on a park bench and let our mind wander, taking in the trees and flowers, noticing birds and squirrels, feeling the breeze. This gentle decompression in nature is actually critical to helping us restore our ability to pay attention. We need breaks where our minds can just go slack and subconsciously take in the complexity of the natural world. Researchers are still trying to figure out the ideal “dose” of this green medicine, but benefits have been seen with just 10 minutes.
The Trump administration’s proposed rule redefining the term “Waters of the United States” (WOTUS) within the Clean Water Act is a direct assault on the health and well-being of American communities nationwide. The proposed definition severely limits which waterways and wetlands are protected from pollutants, and could have catastrophic effects on the quality of the nation’s water, human health, the economies of communities, and the viability of wildlife populations.
ASLA supports having one clear and consistent definition of WOTUS that balances the need to have safe, healthy bodies of water with commerce and sound development practices. The proposed rule change significantly alters that balance, endangering communities and ecosystems while allowing polluters to adversely affect communities and ecosystems well beyond the boundaries of their property.
The fact is, clean water is good business and polluted water is not. A WOTUS Rule should ensure healthy drinking water, reduce adverse health consequences, bolster communities reliant on tourism and recreation, and facilitate place-making for coastal communities. This irresponsible rule change will undermine those goals.
It is particularly regrettable that this rule would go into effect at a time when climate change is already wreaking havoc with fragile environments, particularly those in flood-prone areas. Increasingly frequent and intense storms will, by definition, affect the dry riverbeds and isolated wetlands that this new rule would exempt from protection. This rule would make a bad situation even worse.
Landscape architects work at the nexus of the built and natural environments and are at the forefront of planning and designing water and storm-water management projects that help to protect and preserve our nation’s water supply and enrich the lives of communities. The administration’s replacement rule would be a drastic step backward from the commitment to clean water for all Americans that is at the heart of the original Clean Water Act and the WOTUS rule, and ASLA will work to oppose this proposal.
Hitesh Mehta, FASLA, is president of HM Design, which has completed planning, architecture, and landscape architecture projects in more than 60 countries. He is an international expert in sustainable tourism, including wildlife conservancy planning and eco-lodge development. Mehta is also the author of Authentic Ecolodges (Harper Design).
In more than 60 countries, you have worked on some of the finest sustainable tourism planning and eco-lodge projects in the world, including the Crosswaters Ecolodge in China, which won two ASLA professional awards. National Geographic has called you a pioneer of sustainable tourism. What are the top three lessons you have learned from your many projects working with local and indigenous communities?
Lesson number one: Never judge people from the way they look. Indigenous people have lived on their land for thousands of years. Through storytelling and personal experiences that have been passed over generations, they have built knowledge and wisdom crucial to every project.
Lesson number two: Empower local people from day one, especially women and children. At home, women make a lot of the decisions, and youth are the future. Bringing them into a project on day one helps ensure a sustainable project. You want to give them ownership. It’s a ground-up approach rather than top-down.
Lesson number three: No matter how much of an international expert you are, no matter how much research you have done, and how much knowledge you have acquired, always go into every project without an ego. Go with good listening skills first. Once you’ve heard local peoples aspirations, needs, etc.; gathered on-site information; walked the site with the locals; and have conducted a metaphysical site analysis, slowly share what you can bring to the table, making sure you let them know what they bring to the table is equally important.
Indigenous communities are in the front lines in the fight against climate change. How do you empower them in their fight to protect endangered ecosystems and their own livelihoods? Are there any projects that serve as models?
Indigenous communities, especially in the less developing world, are greatly affected by climate change. A lot of these communities live in the tropics. Especially in Africa, drought and the lack of drinking water are big issues. This in turn, causes food security problems. In Kenya, where I am still a citizen, the Maasai look at their cattle as their economic lifeline. That’s what keeps them going. If there is drought, there is no grass. There’s nothing to feed the cattle, and it can become a serious issue, because this is their security.
A project that serves as an exemplary model is one in which I led a team of local Kenyan consultants and where we worked together with the clients — the Koiyaki Maasai community — to help create an ecotourism and conservation destination called Naboisho Wildlife Conservancy. Previous to our intervention, the community had subdivided their 50,000-acre land into 50-acre parcels owned by 500 families. But every family had their cattle and goats, which caused the land to be overgrazed. Lack of grass and presence of cattle kept all the wild animals away.
The Maasai decided to consolidate all their land and brought in private lodge operators — eco-tourism companies — as a way to generate income for them. The Maasai all moved to neighboring lands they also owned. The private partners contracted us as protected area ecotourism planners, and, together with the Maasai, tourism and conservation stakeholders, we created an integrated sustainable tourism, biodiversity, and grazing master plan for the conservancy.
With five small twelve-room tents and lodges, money started flowing directly into every Maasai’s home at the end of each month via their mobile cell-phones. They no longer had to rely solely on cattle for their livelihood. Wild animals started coming back, because cattle mainly grazed in neighboring areas. And the tourists are paying big bucks to have quality guided safari experiences. Creating a wildlife conservancy was a win/win for everyone: the tourists, the private partners, flora and fauna and of course the Maasai and their cattle. During droughts, cattle are only allowed into the conservancy in certain controlled areas. The conservancy fees provide the Maasai community with a sustainable livelihood and ensure the conservation of the wildlife in this vital corridor of the Maasai Mara ecosystem.
As populations grow around the world, but also in sub-Saharan Africa, human and wildlife conflicts are becoming more prevalent. How can we protect endangered species while also ensuring people’s livelihoods? Are there models that show the way?
There are many models, particularly in Africa, and it has become mainstream to go in this direction. A project that I worked on many years ago that is still a good case study is the Virunga Massif Trans-Boundary protected area. Virunga Massif straddles and borders of three East and Central African countries: Uganda, Rwanda, and Democratic Republic of Congo.
Each country has a national park along their respective borders. This region protects the only remaining populations in the world of mountain gorillas. The parks are bordered by dense populations of local peoples, and there are human-wildlife conflicts with gorillas going out into the fields. We prepared an integrated sustainable tourism and biodiversity master plan for the whole region. When we began the master plan in 2005, there were only 600 mountain gorillas, and the latest count is 1,004!
Apart from conserving important habitat, the master plan also proposed several eco-lodges at the edge of the parks. All of them have now been built and are financially successful. The demand to see the mountain gorillas is so high that eco-tourists are paying $1,500 for one hour to be with these great apes. There’s a one-year waiting list!
What’s great is that some money is channeled straight to local communities, which now see the importance of maintaining the gorillas’ habitat. The communities no longer take firewood from the forest because they earn a living from gorilla tourism and the eco-lodges bring in a lot of money from guests, with part of the profits used to benefit these communities.
A heart-warming part of the master plan just got realized five months ago on the Uganda side of the Virunga Massif in Mgahinga National Park. The Batwa, indigenous peoples, who used to live in the forest but had been chased out when the National Park was created in 1991, have now been re-located to a new village at the edge of the park and act as guides, taking visitors into the forest in the National Park, and showing them about their lives and connections with the forest. An eco-lodge where I had provided site planning consultancy, funded the Batwa village and Visitor Center, so the Batwa community could share their culture and live closer to the forest instead of the nearby urban town of Kisoro.
You have said we cannot have true sustainability without incorporating the spiritual. This belief is central to your metaphysical or sixth-sense approach to planning and designing projects, which you have also trained other planners and designers to apply. What is the core idea you want people to understand?
For the longest time, pragmatic environmentalists have been talking about the triple bottom line of sustainability — environmental, economic, and social. But in my work, I have found that without respecting the fourth element — spiritual — one cannot have sustainability. What do I mean by spiritual? Spirituality is the energy embodied in any place. The metaphysics of a place. The intangible aspects that cannot be measured by modern science. We need to respect this embodied energy to create a sense of place. The sacred space.
Feng Shui is a well-used example of the spiritual aspects of sustainability — the yin and the yang, the chi, and how to use that energy to create an amazing experience in which you have a spiritual connection with the site. Similarly, for over 8,000 years, the Indians have been applying principles of design, layout, measurements, ground preparation, space arrangement, and spatial geometry called Vastu Shastra, which is even older than Feng Shui. Vastu Shastra is the ancient Indian science of harmony and prosperous living by eliminating negative energies and enhancing positive energies.
Native Americans also have a strong spiritual connection with their lands. When they take you on a walk of their country, they will point at a hill and say “this is our sacred hill” and when you look around, there are probably several others that look the same. So why is that hill sacred and not the others? It’s because there is a sacred energy embodied in that particular hill. My job as a landscape architect is to work with indigenous communities, so they can identify all those areas sacred to them. And then protect them.
If the clients do not believe in these traditional ways of looking at the land, I propose the use of each one of our six senses to immerse into the site to understand the energy. Connect deeply to the land through the ears, mouth, eyes, nose, fingers, but most importantly through the sixth sense: when you become a part of the site and feel its energy. That is the crucial element of trying to create a project that’s sustainable, but also which creates a beautiful sense of place.
As part of your work of Landscape Architects Without Borders, you have provided pro-bono planning and design services to aboriginal tribes in Australia and other communities. How do you enable them to incorporate their landscape spirituality into a contemporary place designed for themselves but also tourists?
We worked with the Quandamooka peoples of Queensland in Australia. They were the first aboriginal tribe that managed to get their land back from the white government in an area so close to a major city; Brisbane in this case. The land they got back was part of an island and has the second most popular camping sites in Australia.
However, the aboriginal peoples do not have camping site management experience, so we came in to help them build an ecotourism experience that would help them share their culture with guests and help make more money than before. We designed and built two glamping eco-shacks as examples of what they can achieve with enhanced camping experiences.
In the gardens, we proposed for the planting of bush tucker plants. The aboriginal peoples, who live in the outback have these special plants they eat called bush tucker. With their knowledge and wisdom, we created a beautiful indigenous garden that included both bush tucker and medicinal plants.
You are a proponent of ego-less design, which is characterized by a deep respect for the environment and all of its inhabitants, existing cultures, and vernacular styles. Can you explain how you came across this design philosophy? What about your upbringing, your religious heritage, shaped that?
My childhood has heavily influenced the work I do in landscape architecture. My upbringing is in the philosophy of Jainism, which is one of the four main philosophies that came out of India. It’s by far the least known, because Jains don’t believe in preaching.
One of the main tenets of this philosophy is a Sanskrit concept called Ahimsa, which means non-violence to fellow beings, and non-violence to all other beings as well. In my family, we’ve been vegetarians for at least 3,000 years. The respect is so deep for other beings that Jain monks in India sweep the floor before they walk so they do not step on and kill any ants.
In true Jainism, they believe plants have feelings. In fact, modern science is confirming this, but my ancestors have believed this since 1,000 BC. True Jains don’t eat anything that grows below the ground — no potatoes or carrots — because every time you pick that plant, it’s dead. So you only pick a vegetable or fruit from a tree that continues living after you picked what you want. That is deep respect, even to plants. It’s all about low-impact living. This is the conservation ethic I practice in my work.
My projects are low-impact designs that respect everything. I practice a non-homocentric approach to planning, where everything is equal. You can call it vegan or ahimsa design and planning. I design non-violent spaces. For example, I identify all native species and make sure none of them are cut. And in all our projects, we only specify native plants.
And, personally, I have been practicing a vegan lifestyle for 13 years.
Lastly, you have called yourself a “holistic, contextual designer.” How do you think this is different from being a planner or landscape architect?
For me, there’s a big difference between holistic and contextual design. Holistic is when in my projects I look at animals and plants as my clients, too. So, when human clients come to me, I tell them: I see you as half of my clients, but the other half are the animals and plants. And when I perform a beautiful marriage of the two, we will have a holistic yet sustainable project.
Local communities are an important part of the holistic process. I involve them from the beginning. Local consultants also bring in amazing knowledge and wisdom. So, I consider the local consultants and communities, fauna, flora, and, of course, the clients’ financial needs, because a project has to be profitable for it to function. That is the holistic side.
I also look at myself as a contextual designer. I like to create projects in context with their cultural and physical environments. For me, placing in a glass, aluminum, and concrete building in the middle of a remote area with rich cultural architectural heritage is not contextual. My office carries out research both off-site and on-site in order to discover the local vernacular styles before starting on any project. We use a landscape design approach called the “continuity of the vernacular.”

Option 2: Watch a 3D 360 Video on Samsung Gear VR
If you own a Samsung Gear VR headset and compatible Samsung phone, go to Samsung Gear via the Oculus App and search for “Brooklyn Bridge Park” or “ASLA” to find our video.
Why Brooklyn Bridge Park?
ASLA selected Brooklyn Bridge Park because it won the ASLA 2018 Professional General Design Award of Excellence. Less than one percent of all award submissions receive this honor.
Our esteemed jury, made up of leaders in the field, described Brooklyn Bridge Park this way: “The plan allows for and encourages different experiences in the different spaces, from being wide open and being fully engaged with the people around you to intimate, forested places. It’s remarkable.”
The award also highlights Brooklyn Bridge Park because it’s a prominent example of how to transform abandoned post-industrial waterfronts into spaces for people and wildlife. These spaces litter cities and represent so much untapped potential.
Why Virtual Reality?
The communications world is increasingly image- and video-driven. With video, you can pack in even more information about a work of landscape architecture, much more than you can in simply a photo or text. With video, you can get a sense of the sight, sound, and “feel” of a place. You can see people interacting with the design, bringing it to life.
Virtual reality takes video to the next level. As you move your phone or VR headset, you control your experience in the landscape. It more closely mimics the experience of exploring a place in person. In part, it recreates that sense of discovery one gets in real life.
Why did ASLA make this VR film?
Virtual reality has proven to be a powerful tool for explaining how the places people love – like Brooklyn Bridge Park – are designed experiences. Virtual reality can educate the public about landscape design in a compelling way.
The video has multiple goals: promote the potential of virtual reality among the landscape architecture community, which totals approximately 25,000 design professionals in the U.S. and Canada; explain the incredible value of landscape architecture to the public; and demonstrate the ability of landscape architects to turn an unloved place like a cut-off, post-industrial waterfront into a beloved community park.
Why should landscape architects use VR?
Virtual Reality is a powerful tool for landscape architects, architects, planners, and developers – really anyone involved in designing our built and natural environments. In the example of Brooklyn Bridge Park: many will never have the opportunity to visit the park in person, but with our video, they can get a good sense of what’s it like to be there.
For landscape architecture firms, this is an excellent way to really show clients that a place they’ve designed works – that people enjoy hanging out there, that kids love playing there, that people are drawn to events there.

Glenstone’s Landscaping Is as Mindful as its Artwork– The Washington Post, 10/2/18 “When you visit the expanded Glenstone Museum, you may find the contemporary artwork to be moving, provocative, weird or simply inscrutable, but one aspect of the experience will be constant: its mindfulness.”
A Walk in Moscow’s Grand New Park, Created by an American– CBS News, 10/7/18 “The hottest selfie destination in Russia’s capital sits at the end of an elegant V-shaped walkway in Moscow’s Zaryadye Park. The park itself is brand new – the result of an international collaboration led by New York-based architect Charles Renfro.”
Humans are essentially super-organisms or holobionts made up of both human cells and those of micro-organisms, such as viruses, bacteria, archea, protists, and fungi. Researchers now know the human body hosts a comprehensive ecosystem, largely established by age three, in which non-human cells vastly outnumber human cells. The latest study from the American Academy of Microbiology estimates each human ecosystem contains around 100 trillion cells of micro-organisms and just 37 trillion human cells.
But while rainforest or prairie ecosystems are now well-understood, the human ecosystem is less so. As researchers make new discoveries, there is a growing group of scientists who argue our microbiomes are deeply connected with our physical and mental health. The increased number of prebiotics and probiotics supplements on the shelf in drug stores and supermarkets, and availability of fresh pickles and kimchi in local farmers markets, are perhaps testaments to this increasingly-widespread belief.
Richard Wener, an environmental psychologist at NYU, explained how our built environment is filled with micro-organisms. “The walls of our kitchen and bathrooms are covered in bacteria; most of them aren’t pathogenic.” The micro-organisms found in our environments are constantly interacting with our microbiomes, so we are “perpetually assembling and re-assembling different species.”
For Wener, this begs the question: “What is an individual?” If we are constantly evolving with the micro-organisms in our environment and therefore changing our composition, “what individual are we talking about?”
While our microbiomes may evolve, they still have a distinct signature. Researchers can now identify people by their unique microbiotic markers — crime-scene microbes are now analyzed in forensic studies to identify who was at a location.
Places have unique microbiotic signatures as well. Through their PathoMap project, Weil Cornell Medical College organized citizen scientists to examine the bacteria in subway stations and found stations had “consistent signatures.” The microbes in stations near hospitals were different from neighborhood signatures. “The microbes really depend on who lives there.” (See data visualizations of the findings).
So can we design the city in terms of microbial species? Can we design buildings and parks to create “selective pressure that supports biotic life that is good for humans?”
Turns out good microbes can be put to better use while bad ones can be suppressed.
In Brooklyn’s Gowanus Canal, a highly-polluted Super Fund site, researchers took samples of sludge at the bottom of the canal and found bacteria had been digesting some of the worst industrial waste for decades. “They co-evolved to eat solvents and toxins.” At a slow pace, Wener thinks these bacteria could actually clean-up the entire canal. Through interventions, “we could encourage the growth of this bacteria.”
Buildings could be designed to kill off pathogenic bacteria and support the healthy microbes in our biomes. Wener said a recent Brazilian study found pathogenic bacteria, which comes from people, thrive in closed spaces. In open air environments in the Brazilian rainforest, where domesticated and wild animals roamed through indigenous villages, there were no pathogenic bacteria, but in closed building interiors found in Brazilian cities, researchers found many. The conclusion: If you increase exposure to light and air flow in buildings, you will reduce dangerous bacteria.
The incredible increase of allergies among Western populations may be caused by our “sterile, germ-free environments” that cause our immune systems to over-react to everything from nuts to mold and pollen. Dr. Brett Finlay and Marie-Claire Arrieta even wrote a book exploring this:Let Them Eat Dirt: Saving Your Child from an Over-sanitized World.
Wener said we have created cities that reflect our fear of bacteria; instead we must create microbial-inclusive cities that improve our health. “Most microbes in our bodies have co-evolved with us. They are important to our vital functions. The future of urban planning and design should support healthy microbes.”
As part of this vision, landscape architects could design parks and plazas to be filled with accessible garden plots and healthy soil-based play areas that let both adults and kids get dirty. We could design for holobionts instead of just people, boosting the health of the collective urban microbiome in the process.
A new short film narrated by award-winning actor Leonardo DiCaprio seeks to raise public awareness about pollinators, which includes bees, bats, butterflies, birds, and other mammals; the important ecological and economic roles they play; and the threats they face. The film was produced by Tree Media and directed by Matthew Schmid.
Pollinator health is the rare issue that spans the political spectrum. ASLA has worked with the non-profit Pollinator Partnership to turn this bipartisan goodwill into government policy.
In 2015, ASLA successfully lobbied for inclusion of pollinator-friendly management practices in the 2015 FAST Act. The law instructs the U.S. department of transportation to implement integrated vegetation management, reduced mowing schedules, and planting of native, pollinator-friendly species on highway roadsides. In 2016, the Federal Highway Administration issued guidance to state departments of transportation on how to implement pollinator-friendly habitats on the 17 million acres of roadsides across the country.
Despite the bipartisan consensus, the plight of pollinators remains a relatively obscure issue among the wider population. The producers of Pollinators Under Pressure hope to change that, and have made the film available for free online, making it a valuable tool for those seeking to educate others about the issue.
Climate change is intensifying the negative impacts of standard development practices and is putting people and communities across the United Sates at risk. The American Society of Landscape Architects (ASLA) convened an interdisciplinary Blue Ribbon Panel on Climate Change and Resilience in September 2017, and this week ASLA released a blueprint for helping secure a sustainable and resilient future that summarizes the panel’s work and recommendations.
Promote holistic planning and provide multiple benefits
Take into account environmental justice, racial and social equity
Reflect meaningful community engagement
Regularly evaluated and reviewed for unintended consequences
Address broader regional issues as well as local and site-specific concerns.
Smart Policies for a Changing Climate also found that:
Designing and planning in concert with natural systems promotes resilience, capitalizes on the benefits of natural systems and provides greater long-term return on investment.
Key strategies include use of green infrastructure, native plants, urban and suburban tree planting plans, and healthy soil management practices.
Compact, walkable, and transit-oriented “smart growth” communities reduce energy use and are climate smart.
Special attention must be paid to vulnerable communities in coastal and inland flood plains and underserved and low-income communities.
Transportation should be considered critically as not only a connection point between home to work/services, but also as a source of greenhouse gas emissions, and a contributor or detractor to a community’s appearance and function in light of a weather event.
Agricultural systems must be addressed because they are being stressed by unsustainable farming practices and farmland is being lost to expanding development and sprawl.
“Our nation, states, counties, and cities are looking for solutions to mitigate the risks from the changing climate and extreme weather events,” said Nancy C. Somerville, Hon. ASLA, ASLA executive vice president and CEO. “With this report, landscape architects and their design and planning colleagues forward public policy recommendations that can make communities safer while taking climate change and existing natural systems into account.”
ASLA released the report at an evening reception and candid discussion yesterday with Somerville, and ASLA Blue Ribbon Panel members Adam Ortiz, director for the Department of the Environment for Prince George’s County, Maryland, and Diane Jones Allen, program director for Landscape Architecture, the College of Architecture, Planning and Public Affairs at the University of Texas at Arlington and principal landscape architect with DesignJones LLC.
We have provided a platform for landscape architects, public officials, and other design and planning professionals to share their views on how to help communities adapt to climate change through smart design policies. Go to https://climate.asla.org.

Some quotes from panelists on the importance of adopting effective public policies and landscape architecture design solutions:
“The plans we’re going to have in the future to deal with living with water have to be more realistic. We have to live with the acknowledgement that there will be hurricanes and areas that naturally want to flood. How do we build differently as opposed to thinking we can keep water out?”
Diane Jones Allen, ASLA Program Director for Landscape Architecture, the College of Architecture, Planning, and Public Affairs at the University of Texas at Arlington
“We have a number of antiquated policies within governmental structures. Reevaluating them every five years or so would help us to reflect what is currently happening and to better project how we should design communities to be able to proactively respond to such changes and challenges.”
Dr. Dwane Jones, Ph.D. Director of the Center for Sustainable Development + Resilience at the University of the District of Columbia
“All public projects really have to be interdisciplinary. They have to incorporate the local culture, the local economy, forward-thinking design concepts, as well as good engineering. All that together, in a very thoughtful way that respects the complexity of our society, is a way to make a sustainable project that people enjoy and love.”
Adam Ortiz Director for the Department of the Environment for Prince George’s County, Maryland
“One of the things we need to be doing is do a lot more experimentation. Sometimes you just need to be able to try things and see if that solution can take you forward. If it’s not a good solution, let’s try something else. That kind of creativity and ideas is really what innovation is all about.”
Vaughn B. Rinner, FASLA, SITES AP Immediate Past President, American Society of Landscape Architects
“Our standard development practices are not sustainable, but when we understand and work with natural systems, we can build safer and healthier communities.”
Nancy C. Somerville, Hon. ASLA. SITES AP Executive Vice President and CEO, American Society of Landscape Architects
“My hope is that we embed true kinds of community engagement, justice, and equity into our focus on climate change and resilience. We need to really do that in a way where it’s not so scientific. The social engineering matters as well. It’s what you’re doing in your profession that impacts people and makes those impacts equitable.”

What’s more, Gedamke says that the world’s oceans are getting noisier still thanks to human activity. At a recent round-table discussion hosted by the Renewable Natural Resources Foundation, Gedamke discussed his team’s research on this significant but overlooked impact of human activity on the not-so-silent world.
Water, it turns out, is an excellent conductor of acoustic energy. “Sound travels incredibly efficiently underwater,” said Gedamke. He pointed to the 1991 Heard Island Feasibility Test, in which sounds emitted from underwater speakers off the coast of Australia were heard by researchers on the other side of the planet.
Whales and dolphins have adapted to exploit this property of water to communicate over large distances, but these adaptations also make them vulnerable to adverse effects from human sounds.
Gedamke’s team, however, is most interested in the chronic effects of years’ worth of sound pollution on marine mammal life. “We’re trying to shift our focus from the acute – the immediate, loud sound that causes an animal to change its behavior – to the broader effects of all this introduced sound changing their habitat.”
Part of the challenge Gedamke and his team face in their research is a lack of consistent data. The historic record of ocean noise levels is piecemeal, meaning it is difficult to make direct comparisons over time. The researchers are trying to address this with a new system of recorders that were deployed in 2014. These will allow for more accurate assessments of how the ocean’s sonic landscape is changing over time.
Gedamke’s team is also using GIS to map areas of high-noise intensity. When those are overlaid with maps showing areas of wildlife population, they could help identify areas and populations most at risk from harmful noise pollution.
There are many risks of a noisier habitat for marine life. Ambient noise could mask sounds that allow certain species to detect their predators, or vice versa, which could lead to food chain disruptions and ecological imbalance. It could also make it more difficult for individual animals to communicate with members of their own species, interfering with behaviors like hunting and mating. Proximity to loud sources of sound could lead to injury or hearing loss.
According to Project Drawdown, offshore wind turbines are an important tool for reversing global warming, with the potential to reduce atmospheric CO2 by 14.1 gigatons by 2050.
Wind turbines, both on and offshore, have also drawn criticism from environmental groups in the past for their potential impacts on wildlife, especially birds.
The risk of rising ocean noise fits into a larger pattern of disregard for the impact of human activity on marine habitat. From warming water temperatures to toxic chemical spills to swirling islands of plastic garbage, the world’s oceans are bearing the brunt of some of the most harmful industrial practices of the 20th and early 21st century.
The recent BBC nature documentary series Blue Planet II illustrated the scope of these impacts in its final episode, “Our Blue Planet.” In the episode, narrator David Attenborough warns that “the health of our oceans is under threat now as never before in human history.”
Among the harmful impacts of human behavior are overfishing, plastic entering the food chain, and yes, noise. “Man-made noise is now everywhere in the ocean, and it has an effect on marine creatures of all kinds,” says Attenborough.
The Blue Planet team follows marine biologist Steve Simpson, who researches how fish use sound to communicate, as well as how man-made sound interferes with that ability.
While it seems to be a complicated issue, for Simpson, the way forward is clear: “We can choose where we make the noise, we can choose when we make the noise. We can directly control the amount of noise that we make, and we can start doing that today.”
