ASLA 2011 Professional Analysis and Planning Honor Award. Making a Wild Place in Milwaukee’s Urban Menomonee Valley, Milwaukee by Landscapes of Place / Nancy Aten

The Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES), an international organization committed to strengthening the role of science in public decision-making on biodiversity and ecosystem services, seeks expert landscape architects, ecologists, and others with policy experience to assess its latest research. The call for more engagement was made at a recent presentation at the Ecological Society of America (ESA) in Washington, D.C.

IPBES explains the reason for its existence on its web site: “Biodiversity from terrestrial, marine, coastal, and inland water ecosystems provides the basis for ecosystems and the services they provide that underpin human well-being. However, biodiversity and ecosystem services are declining at an unprecedented rate, and in order to address this challenge, adequate local, national and international policies need to be adopted and implemented. To achieve this, decision makers need scientifically credible and independent information that takes into account the complex relationships between biodiversity, ecosystem services, and people. They also need effective methods to interpret this scientific information in order to make informed decisions. The scientific community also needs to understand the needs of decision makers better in order to provide them with the relevant information. In essence, the dialogue between the scientific community, governments, and other stakeholders on biodiversity and ecosystem services needs to be strengthened.”

To reiterate, Douglas Beard Jr., National Climate Change and Wildlife Center, U.S. Geological Survey, and a co-lead for the science component of IPBES for the U.S. Delegation, said: “It’s always better to hear from a diverse group of people.”

Established in 2012, IPBES has convened multi-disciplinary groups of experts to conduct public assessments around the globe. With 114 member countries, IPBES is dedicated to becoming the leading international organization on ecosystem services.

Assessors will help make progress on the status of pollinators, pollination, and food production; scoping for a set of global and regional assessments of the status of biodiversity and ecosystem services; and scoping for a thematic assessment of land degradation and restoration.

If you are interested in nominating someone or being nominated for an upcoming call, please contact Clifford Duke at ESA, which coordinates the U.S. stakeholders.

Helsinki / Wikipedia

The Guardian‘s excellent environmental coverage has been supplemented by a new section on cities, supported by the Rockefeller Foundation. Here, we learn about an ambitious plan in Helsinki, Finland, to create a revolutionary “mobility on demand” system by 2025. The system would enable all “shared and public transport” to be paid for with a single payment network available via smartphones. People would create their own transportation infrastructure from scratch. This is a complete rethinking of urban mobility for the age of ubiquitous connectivity.

The Guardian writes: “The hope is to furnish riders with an array of options so cheap, flexible, and well-coordinated that it becomes competitive with private car ownership not merely on cost, but on convenience and ease of use.”

Helsinki residents will use a new app to simply indicate start and end points, with perhaps a few preferences for mode of transit. “The app would then function as both journey planner and universal payment platform, knitting everything from driverless cars and nimble little buses to shared bikes and ferries into a single, supple mesh of mobility.” The app would be like Google Maps mated with a public Uber, but across all transportation options.

This city-wide mobility-on-demand system may build off of the Helsinki Regional Transport Authority’s new minibus service, Kutsuplus, which already lets riders indicate their own origins and destinations. With Kutsuplus, “requests are aggregated, and the app calculates an optimal route that most closely satisfies all of them.” Kutsuplus is expected to reduce car ownership, and even Zipcar membership.

The Guardian wonders whether this system can actually work in practice for everyone though. Riders would need a smartphone to be able to buy in. While this may work for upwardly mobile segments of Helsinki, does everyone there actually own a smartphone? What about the elderly, or people with disabilities?

Getting cost right will also be important. As an example, “Kutsuplus costs more than a conventional journey by bus, but less than a taxi fare over the same distance – and Goldilocks-style, that feels just about right.” How much will people pay extra for mobility on demand? And should they even pay extra, if this is to be a publicly-managed service?

Furthermore, could this model actually work elsewhere? The Guardian asks whether mobility on demand will be as effective in the spread-out, low-density suburbs of Helsinki.

And further afield, is this model transferable? Cities in the developing world that don’t have well-established public transportation systems (buses or subways) already rely on a network of private mini-buses and vans to move people around. These form a decentralized network that also responds to supply and demand. Could a Helsinki model be superimposed on such systems? And could it augment recent developments? Many developing world cities are moving towards more a more integrated public transportation network, often with new bus-rapid-transit (BRT) systems as the backbone. According to The City Fix from EMBARQ, 31 million urbanites now use BRT.

App-based urban transportation experiments are underway, perhaps showing the way to a new form of mobility. Almost all major urban transportation systems in the U.S. and Europe have their own apps that enable easy route planning; that’s a new thing. San Francisco is even testing an app to manage supply and demand for parking spaces. Uber and other taxi-on-demand services are now ubiquitous in the developed world, and have even caused widespread protests in Europe. But can an app really kill the car?

What Makes a City Great? / Sasaki Associates

A new survey commissioned by planning and design firm Sasaki Associates asked 1,000 urbanites in San Francisco, Chicago, Austin, New York, Boston, and Washington, D.C. what they love most about their city. The findings, which cover diverse aspects of city life, offer truly fascinating insights for urban planners, landscape architects, and architects. One example: 60 percent of residents of these cities say they will still be in the city five years from now. Here are some other highlights.

What do urbanites love most about their cities? 

More than 40 percent cited the restaurants and food; while 32 percent said local attractions; 24 percent said historic places and landmarks; 21 percent said cultural offerings; 17 percent said parks and public spaces; and 16 percent said fairs and festivals. Some 15 percent said “the people,” while another 10 percent said they like the architecture the most, and 9 percent said the local sports scene.

And when asked, “what would get you out of your neighborhood?,” the findings are largely consistent with preferences listed above: 46 would venture out for a new restaurant; 25 percent would travel for a new store; 24 percent for a new cultural event; while just 18 percent would schlep to check out a new park or green space.

Where do urbanites’ favorite experiences happen?

While only 18 percent will travel across town for a new park, interestingly, a majority of people (65 percent) remember their favorite city experience taking place outdoors — either in a park or on a street. (A minority [just 22 percent] said their favorite experience happened in a building).

Of outdoor spaces, 47 percent say waterfronts are their favorite. Another 31 prefer large open parks, while 14 percent prefer small urban spaces, and 8 percent love their city’s trail system the most.

So where should cities make future investment in parks and open space? “41 percent support investment in making the waterfront more accessible and appealing; 40 percent would like to see more large parks that support both passive and adventurous activities; 37 percent wish their cities would make streets more pedestrian/bike friendly; 36 percent support adding outdoor music and entertainment venues; and 31 percent desire more small urban parks.”

What makes a city’s buildings iconic?

Some 36 percent said the historic nature of the building, while 30 percent said “great architecture,” and another 24 percent said a building’s “unique design.” A majority will (57 percent) will stop and look at a historic building, while just 19 percent will do the same for a modern one.

What do urbanites like least about getting around in cities?

More than 40 percent said there’s “too much traffic,” while 23 percent cited the lack of parking. Some 14 percent said public transportation is not up to par, and 9 percent said biking is dangerous. Another 7 percent pointed to things being “too spread out,” while another 7 percent complained that sidewalks are too crowded.

These complaints reveal how Americans, even urbanites, get around: 58 percent use cars frequently, while 29 percent use public transportation. Another 10 percent try to walk everywhere and just 2 percent use bikes.

Surveys like Sasaki’s are important. We need to attract as many people as possible to cities, because urban life is central to a more sustainable future. In cities, per-capita carbon emissions and energy and water use are all much lower. But beyond the metrics, cities can just be great places if they are designed to be livable and beautiful, filled with outdoor spaces, historic buildings, and efficient transportation systems.

In keeping with Sasaki’s multidisciplinary approach, the team who put together the survey is comprised of a planner, landscape architect (Gina Ford, ASLA), and an architect, as it should be when dealing with all things related to our built environment.

Helen Schneider / Naturbad Riehen

The people of Riehen, a small city near Basel in Switzerland, have long wanted a new public swimming pool to replace their “obsolescent baths” by the River Wiese. In the late 1970s, the city government even launched a design competition. Unfortunately, the initial vision was never unrealized, but, just a few years ago, the Swiss architecture firm Herzog & de Meuron got to thinking about new possibilities. They write: “the changed perspectives brought by the intervening years prompted the idea of abandoning the conventional pool concept, with its mechanical and chemical water treatment systems, in favor of a pool closer to a natural condition with biological filtration.” The citizens liked the idea, giving it the thumbs-up in a municipal vote.

Herzog & de  Meuron say their new approach enables “technical systems and machine rooms to vanish.” The new natural approach means no chlorine or other chemicals are added. Filtering plants help keep the water clean.

Biological water treatment basins, which are the “heart of the baths,” also play a major role. DesignBoom tells us: “The process is modeled after natural, terrestrial water purification, through layers of gravel, sand, and soil.” Herzog & de Meuron worked with Swiss landscape architecture firm Fahri und Breitenfeld on the system.

Amazingly, this all-natural approach enables the bath to accommodate up to 2,000 people a day, who enter as they would a small pond. DesignBoom writes: “Its edge takes an irregular and vegetated boundary, with various methods for guests to enter the water. These include a gently sloping gravel beach, staircases, as well as wood docks that allow for a jump.”

The structures around the natural pool are modeled on the local “Badi,” or Basel’s “traditional wooden Rhine-side baths.” Timber walls provide screen on the north and west sides, with built-in recliners for sunbathing.

The southern view, which faces the river, is open. On the east side, the wood wall opens for the entrance.

There are also open-air showers and a small cafe.

ozone

Danica Lombardozzi / National Center for Atmospheric Research

Community Radio of Northern California asks: “What if you could look at the plants in your garden in order to learn if the air around you is clean or dirty?” Turns out the National Center for Atmospheric Research (NCAR) in Boulder, Colorado, enables us to do just that with their new ozone garden. There, the plants show a visible reaction when ozone reaches a certain level.

Ozone is an oxidant in our atmosphere that can be harmful to both people and plants. NASA, which also has an ozone garden for research, further explains: “One of the primary components of air quality is the amount of ozone found in the air we breathe (troposphere). While ozone in the upper atmosphere (stratosphere) protects life from harmful ultraviolet radiation, ozone in the lower atmosphere (troposphere) is a pollutant that damages plants and human lung tissue.” Surface-level ozone can reach dangerously high levels on hot, sunny days, causing create breathing problems, especially for children.

The Environmental Protection Agency (EPA) has set the limit for humans at 75 parts per billion, but Community Radio writes that it’s considering lowering that level. Some plants start showing effects at 40 parts per billion.

NCAR’s test garden has four types of plants, which have been selected for their “sensitivity to ozone.” These include “milkweed, snap bean, potato and cutleaf coneflower.” When ozone begins to take its toll, Danica Lombardozzi, a postdoctoral researcher at NCAR, told Community Radio: “You start to see damage on the leaves. A bunch of little black spots.”

These plants are “like a canary in the coal mine,” said Lombardozzi. When the plants react to the ozone, some of the chlorophyll cells in the plant’s leaves die. “The effect isn’t instant, though – the leaf blackening depends on how long the ozone is in the air and how long the plants are exposed.” Typically, the worst ozone comes in later July and August.

As NASA explains in a comprehensive report about their bioindicator ozone garden, ozone could also be very bad news for the plant world, and, in turn, us. During high periods of ozone, there have been known negative impacts: “Ozone air pollution has been known since the late 1950s to cause significant injury and economic losses to many agricultural crops, herbaceous ornamentals, and native plants.” Forests could also be affected.

Here’s a guide on how to set up an ozone garden as a monitoring station. NASA also created a toolkit that explains how educators and middle school students can create their own ozone garden as a scientific learning exercise.

A Memorial for the Canterbury Earthquakes / Christchurch Central Development Unit

In New Zealand in 2010, an earthquake 7.1 on the Richter scale shook open the earth in a previously unknown fault. Over the next three years, some 14,000 aftershocks hit the residents of the Canterbury region. One particularly devastating quake in February 2011 killed 185 people and damaged much of the city of Christchurch. In fact, up until July 2013, the center of Christchurch was totally cordoned off. Clean up and reconstruction has been intensive and ongoing. One sad statistic: only 20 percent of the city’s original buildings will remain when demolition is complete, writes the Christchurch city government.

In a sign of this city’s great resilience, Christchurch has sponsored a new design competition for a Canterbury Earthquake Memorial. The memorial is designed to be a “unique and lasting tribute to the tragic events that have so dramatically reshaped the Canterbury region and people.” The memorial seems to be needed: “people continue to mourn the losses and deal with the challenges of living in a damaged city.”

The memorial will be on a stretch of Ōtākaro/Avon River, between the Montreal Street bridge and Rhododendron Island. The Christchurch government says the site was chosen because it offers a “quiet, contemplative space” that can conversely also host large events for crowds up to 2,000. A tree-lined route, which includes a “bridge of remembrance,” will connect the memorial to the inner city.

The design competition is open to everyone, all over the world. The entries will be judged anonymously, with only an ID number accepted on the submission form. This is mean to eliminate any possible “professional or personal bias” among the judges.

Entries are due August 22.

Another opportunity: Princeton Architectural Press (PAP) is seeking submission for its cutting-edge Pamphlet Architecture series, made possible through support by the National Endowment for the Arts (NEA). “Pamphlet Architecture is again offering an opportunity for … landscape architects to publish their projects, manifestos, ideas, theories, ruminations, insights, and hopes for the future of the designed and built world. With far-ranging topics including the alphabet, algorithms, machines, and music, each Pamphlet is unique to the individual or group who authors it.”

PAP seeks concepts that “possess the rigor and excitement” found throughout the history of the series. Landscape architects: Register by August 1 and submit your best ideas by September 1. Winners will receive $2,500 to flesh out their proposals.
