Here Comes Everybody

Because building green often has an added cost to it, responsible business / project managers will take a close look at potential benefits, since they are concerned about their bottom line as much as they may be about the environment.

Quoting Clay Shirky in Here Comes Everybody about the new presence of a “social surplus”: many people (in the USA, at least) with a hunger to be of service and to be part of something bigger.  And many people who are concerned about the state of the world – climate change, loss of species, pollution, etc. – are acting in new, sustainable, innovative ways in their daily life: they buy and use biodegradable dish soap, for example.  As a result there is a potential large population of individuals and organizations who may participate in “green building” / “sustainable sites” if it makes them feel good about what they have accomplished in their own gardens / landscape projects and about contributing ideas to a common effort, with only a marginal cost increase.

And it doesn’t have to be all or nothing.  First, because we are in transition – we don’t have all the answers and solutions, we get better and better at sustainable solutions as we go.  Second, because not all “sustainable” solutions work in any given project, and even a small “sustainable” initiative in a project could potentially make the difference for the entire project.

Sustaining ecological areas 2

 

In San Francisco Golden Gate Park has a large resident population of “chronic homeless”.  The watershed of the Guarapiranga Reservoir outside of Rio de Janeiro has a population of 600,000 people (with only half connected to a sanitary sewer).  So what happens if an ecological area is in a densely-populated region? 

The specific areas significant for ecological functions could be identified as if they were ecological areas far away from human populations.  But because the land is in a densely populated area and the value of land is consequently at a premium the specific ecological areas can be assigned land use designations integrated within the context of an overall project or municipal Master Plan.  Typical land use designations for ecological function areas in master plans or municipal plans are “ecological reserve” or “park” but either the Master Plan or a conservation plan should specify much more particularly the role of the land, e.g., for maintenance of gene pools, education, outdoor recreation, or scientific research.

Sustaining ecological areas 1
How is an area with high ecological value sustained?  Common practice, if the area is isolated enough from human population centers, is to set legal land boundaries which include the areas deemed significant for ecological functions plus a “buffer” between the ecological functions areas and the legal boundary.  Ideally a conservation plan is prepared for the protected area (i.e., for the whole legally-protected area).  The conservation plan sets out how to manage human activities in the ecological area to help ensure that the ecological functions are unaffected by human activity or presence.  Legal methods to protect the land might include conservation easement or purchase or donation of the land to an accredited land trust or public agency.

The digital technologies - "green" connection

 

Isn't it a coincidence that things "green" seem to be high on everyone's agenda these days, from kids to corporations, at the same time as the new Web 2.0 technologies are taking hold.  There is a reality that is driving the green agendas of course, what with melting glaciers, ecological fragmentation, spiking energy demand, and trace elements of pesticides in food.  In addition, however, "nature" is a social construct and as we address all these issues (which we must do and do soon and effectively) what we are really doing is changing human perceptions, activities, and relationships, not "fixing" nature.  Actual natural processes are much bigger than us humans and our human actions to “restore” or “conserve” nature are really about different human ways to interact with natural processes.  Read The Fallacy of Wildlife Conservation, a compelling essay, by John Livingston http://en.wikipedia.org/wiki/John_Livingston originally recommended to me by David Suzuki http://en.wikipedia.org/wiki/David_Suzuki .  But the widespread adoption of new communication technologies is doing nothing if not changing perceptions and relationships.

digital is just another "scape."

 

What I am thinking about these days is that architecture / landscape is the physical "platform" or "container" in which social interactions take place.  The interactions are face-to-face, but these days they are also digital.  Did you go to the Outside Lands Music and Arts Festival http://www.sfoutsidelands.com/ last weekend (Aug 22-24 2008) in San Fran?  Lots of great music, apparently, and even though I couldn't be there the most interesting thing for me was the Crowdfire app http://www.crowdfire.net/ that allowed participants to upload, tag, and remix images, text, video, and audio captured on cellphones, resulting in a shared, immersive experience.   

 

What's the connection of Outside Lands with Los Medanos http://www.losmedanos.edu/, or any college campus for that matter?  Answer: I think that the Outside Lands kind of experience will become normative, because the technology is all here.  And the first place that it will become normative is on college campuses, because young adults are so tuned to the new technology.  What does a campus look like when there is an endless, integrative ocean of streaming, tagged, diverse media and online relationships-building for both substantive ("courses") and non substantive ("extracurricular") content overlayed over an ancient tradition of academic discourse and contemporary profit-driven business education?

Sylvia Paull http://www.sylviapaull.com/, who graciously spooned me up just as I gave my left ankle an incredibly painful sprain (why I didn’t go to Outside Lands), commented: “digital is just another ‘scape’."

This is now an immersive, integrative environment

Last year (October 2007) I attended the ASLA’s national conference, which happened to be held here in San Francisco.  So it was easy to attend a lot of the sessions.  One morning there was a plenary session which featured four of the Landscape Architecture world’s leading designers.  They sat on a podium before an audience of what seemed like upwards from 1,000 landscape architects and others.  I was towards the middle of the room and could barely make out the four on the podium.  To overcome this there was real-time video feed presented on two enormous screens above them.  The screens were amplified by color and lighting surrounds to elicit a mood and help the audience focus on the activity on the podium.

It was pretty clear to me, though maybe not to many others, that while the content of the presentation was a comparative discussion of current landscape work among the four, the landscape that we were all participating in in real time was an interactive field.  The physical world consisting of the set was just the basis of the landscape.  The rest of the landscape was the aura of colors and lights, and the live screens – and the half-acre of audience in the darkened hall.

Similarly, the landscape “out there” – city streets, parks, natural areas, sports stadiums, office towers, highways and roads, etc., the kind of stuff typically designed by architects (the buildings), engineers (the roads), and landscape architects (the pedestrian environment and planting / natural areas) – is (just) the basis of our current landscape.  In North American cities, at least, half the population it seems is now walking around with their mobile phones glued to their ears or viewing email and internet content on their Blackberries.  This is now an immersive, integrative environment, in which the local landscape that we walk in is now a part of the virtual environment in which we have quite as deep, engaged, meaningful relationships – and vice versa.

Ten years ago this was not the case, perhaps.  And in ten years from now it seems likely to me that it will be even more integrative, as 3-d content (as in electronic games and virtual communities) becomes more common, accessible, and naturalized. 

Los Medanos College in Pittsburg, California, for which I was project manager at Smith & Smith, is an integrative, immersive environment.  Exterior spaces are shaped for formal ceremonies, daily student use, and local community use, and campus entrances for both function and appearance.  But integral to those exterior spaces are the irrigation, lighting, security, information kiosks, and other systems that are centrally, digitally controlled.  Even the shape of exterior spaces is strongly influenced by the network / utility configuration that is mostly underground, with surface expression in light poles, in-ground vaults, the fountain jets, etc. 

The clue for me for all of this is the very word “landscape”.  “Landscape” ≠ “landscaping”.  “Landscape” means “a composition of man-made spaces on the land” (page 7, JB Jackson 1996 “The Word Itself” in Reading the Vernacular Landscape).  It is only a late 20th Century understanding of the word which misses the evolved, contemporary culture and its arising landscape.

Time to Think about Sustainability

These days thought and feeling about sustainability seems to be arising from every conceivable corner of the world these days, from neighbourhood community action groups to corporate strategists.  Meanwhile design professionals who are inundated with demands for product and services in increasingly short time horizons are also now called on to be experts in sustainability. 

Many architects, landscape architects, interior designers, and engineers are genuinely attempting to provide competent information to their clients – either directly or through specification of materials and suppliers.  However LEED http://www.usgbc.org/ (and similar programs) notwithstanding because of the amount of information available many professionals often find themselves too busy producing “sustainability stuff” without genuine attention to examine and evaluate – “not enough time to think”.
 

Regarding "time to think" about sustainability here are some interesting and worthwhile websites. 

http://www.architectureforhumanity.org/

http://openarchitecturenetwork.org/

http://www.urbanrevision.com/

and http://www.treehugger.com/ also has an architecture and design section.

Such websites aim to collect ideas, designs, and plans for sustainable architecture.  Basically it seems that these websites are leveraging the power of the internet and social networking: the internet makes the information accessible to many people and the social networking applications allow those people to upload and share files and ideas - and not incidentally thereby create a "buzz" and group of users whose size and common interest can attract advertisers and investors. 

The tendency of such websites may be toward something like an architectural "wikipedia" in which anyone can say or present any idea, some of which are actually buildable and being constructed and some are little more than Gulliver’s Travels fantasies.  User beware!  But this is where architectural practice and experience may come in: an important role of an architectural professional these days may be to provide sound judgment on what is real versus what is some well-meaning but starry-eyed wishful dream or worse a manufacturer's hoax greenwash – as much as to provide professional design services and products. 

Still the buildable along with the fantasies on such websites may be worthwhile because they might spark thinking which leads to buildable projects, or provide ideas to be built into real projects.  Whether any of this has any staying power time will tell, as we seem to be in the middle of a green bandwagon bubble.

Landscape and Inscape between landed cultures and subcultures

Landscape and Inscape are the constructed and the construct, respectively.  But how to tell them apart? 

For example, Steen Høyer on the Danish landscape (in Recovering Landscape 1999):

“For the most part, Denmark is a coherent and yet diverse fabric of fields, woodlands, small towns, and gentle, glacial topography bathed in changeably soft and luminous light.  The character of the landscape derives not only form natural conditions but also, and perhaps in larger measure, from a collective and organized approach to its management… The country enjoys a clarity of open order that expresses the Danish democratic and social tradition…”

Is this poetic passage descriptive of the landscape as constructed or is it recounting the cultural construct?  Perhaps for landed cultures (cultures that have a nation state with definable borders) it may seem easier to examine the constructed landscape and harder to get at the cultural construct.

What of the landscapes of Australian Aborigines, Puerto Ricans in the USA, Polynesian Islanders, Inuit, African Americans, Jews, or Chinese in south-east Asia?  It seems that these cultural groups have large populations that are either thinly spread through a very large geographical area, exist within the cultural matrix of other larger groups, or both.  What do their landscapes look like?

Luis Aponte-Pares on Puerto Ricans in New York City (in 2000 Preserving Cultural Landscapes in America):

“… Villa Puerto Rico, a casita, or little house, in the south Bronx…is a source of pride and memory – it articulates and validates the community’s Puerto Rican identity in space.  …casitas stand as cogent metaphors of place and culture.”

An Inuksuk is a stone figure traditionally used by Inuit and other indigenous people in the Arctic.

“Among many practical functions, they were employed as hunting and navigation aids, coordination points, indicators...  The term Inuksuk means 'to act in the capacity of a human.' It is an extension of Inuk, meaning 'a human being'.   …they appear not only on the earthly landscape but in legends and stories, in figures that emerge from the movements of fingers playing string games. These stone figures were placed on the temporal and spiritual landscapes.  http://www.arcticinuitart.com/culture/inuk.html

Yiddishland in one conception refers to the former Jewish pale of settlement in pre war Europe:

“Yiddishland, a mythical and real land that has never appeared on a map of the world, but whose frontiers have forged rivers, crossed oceans and spanned continents…. alive with rabbis, professional marriage brokers, itinerant water carriers, bright-eyed yeshivot students, porters…, plus synagogues, hospitals, cemeteries…” (amazon.com review of Yiddishland by Gerard Sylvain et al.)

In another conception Yiddishland refers to

“…a virtual locus construed in terms of the use of the Yiddish language, especially, though not exclusively, in its spoken form… Yiddishland infers a highly contingent tenacity inherent in any spatial entity defined by language use…” (Jeffrey Shandler 2006 Adventures in Yiddishland)

So what do their landscapes look like?  Constructed cultural signifiers within the larger environment that humanize and/or appropriate the environment and confer cultural meaning to those who thereby recognize the Landscape and read therein the Inscape.

Ecosystem resilience Part II

Gustave Flaubert:  On ne choisit pas son sujet. Voilà ce que le public et les critiques ne comprennent pas.  Le secret des chefs-d'oeuvre est là, dans la concordance du sujet et du tempérament de l'auteur.

One does not choose one’s subject matter; one submits to it.

Ecosystem resilience and stability and security of human communities

While biodiversity may be the basis of resilience, it is not the only foundation for resilience.  Ecosystems depend also on physical, structural characteristics to keep from being overwhelmed.  Some examples:

·        In the aftermath of the tsunami hitting the coast of Indonesia in December 2004 aerial photography revealed that some parts of the coast were hit harder than others.  Research subsequently demonstrated that the coast suffered less damage where the offshore reef was intact.  Apparently, many reefs areas around the Indian Ocean have been exploded with dynamite because they are considered impediments to shipping, an important part of the South Asian economy.  Similarly, the removal of coastal mangrove trees (for residential development) is believed to have intensified the effect of the tsunami in some locations. http://en.wikipedia.org/wiki/2004_Indian_Ocean_earthquake
Damage from the tsunami was reduced by the presence of an extensive, intact mangrove fringe. 2005, Danielson et al. Science 310:643 “The Asian Tsunami: a protective role for coastal vegetation”

·        In the aftermath of Katrina, the hurricane that made landfall August 29 2005 in southeast Louisiana, USA, it was shown that where the offshore mudflats were more intact, the impact of the storm was reduced.  “Barrier islands, shoals, marshes, forested wetlands, and other features of the coastal landscape can provide a significant and potentially sustainable buffer from wind wave action and storm surge generated by tropical storms and hurricanes.  Anecdotal data accumulated after Hurricane Andrew suggest that a storm surge reduction along the central Louisiana coast of about three inches per mile of marsh…  Emergent canopies such as provided by forested wetlands can greatly diminish wind penetration, thereby reducing the wind stress available to generate surface waves and storm surge.  Shallow water depths attenuate waves via bottom friction and breaking…” pp3,15   2006-Jan-26, Working Group for Post-Hurricane Planning for the Louisiana Coast, A New Framework for Planning the Future of Coastal Louisiana after the Hurricanes of 2005. 

·        In the coastal forest extending from the Canadian west coast into the American pacific northwest the bark near the forest floor of Redcedars, Douglas-firs, Redwoods, and other large trees is thick enough to be able to withstand small fires, such as would occur naturally by lightning and that would consume the local underbrush.  Where a fire suppression policy is in place, underbrush builds up – providing fuel for a potentially large and hot fire – which might be hot enough to destroy the large trees.  The Oakland Hills fire of 1991 was at least in part a result of this condition:  “At the fires peak it would destroy 1 home every 11 seconds.  In addition to the winds and the heat, an important factor in the rapid spread of the fire was that it started in an area that was at an interface between developed and undeveloped land. Many of the first dwellings to burn were surrounded by thick, dry vegetation.  In addition, the nearby undeveloped land had even more dry brush along with several groves of non-native volatile eucalyptus trees.  The same conditions contributed to ..the Berkeley 1923 fire.”  http://en.wikipedia.org/wiki/Oakland_Hills_firestorm A major fire near Limantour Beach in Point Reyes National Seashore in October 1995 consumed 48 homes and scorched 12,000 acres (1/7th of the park.)  Some say that Marin County, California (where I live) is a forest fire disaster waiting to happen…
