First-Strike Reforestation

Earlier this month, Macleans looked at the idea of "aerial reforestation," or the large-scale dropping of tree seedlings using decommissioned military aircraft. Of course, we looked at this same plan many, many years ago—and it turns out the same guy is behind this latest round of journalistic interest.

Moshe Alamaro, still affiliated with MIT, had previously been pushing his plan for "using a small fertilizing plane to drop saplings in plastic pods one at a time from a hopper," Macleans explains. The biodegradable canisters would then have "hit the ground at 200 m.p.h.," MIT explained back in 1997, "and imbed themselves in the soil. Then the canisters decompose and the young trees take root. A large aircraft could drop as many as 100,000 saplings in a single flight: Alamaro's system could plant as many as a million trees in one day."

But, Macleans points out, "it wasn’t very fruitful—most pods hit debris during pilot tests and failed to actually take root."

The idea has thus now been "upgraded," using different technical means "to create new forests on empty landscapes."
    The process Alamaro advocates places trees in metal pods that rot on contact with the ground, instead of the low-tech and less sturdy plastic version. He says the process can be adapted to plant shrubs, and would work best in places with clear, loose soil, such as sub-desert parts of the Middle East, or newly habitable Arctic tundra opened up by global warming. “What is needed is government policy to use old military aircraft,” he says, adding that thousands are in hangars across the globe. Although the original pitch failed, Alamaro says the growing carbon market is creating new interest, and he hopes to find funding for a large-scale pilot project soon. Once Alamaro gets planes in the air, the last step, says [Dennis Bendickson, professor of forestry], will be to simply “get people out of the way.”
In this context, it's difficult to resist pointing out Iceland's own soil-bombing campaign: "Iceland is big and sparsely populated," the BBC reported in 2005. "There are few roads. So, Icelanders decided to 'bomb their own country'," dropping special mixtures of fertiliser and seeds "from a WWII DC 3 Dakota"—carpet-bombing subarctic desert in an attempt to make that emptiness flower.

I feel compelled here to point out a brief scene from the film Hellboy 2, in which we see a "forest god" killed in the streets of Brooklyn (roughly 2:36 in this clip); his green and bubbling blood blooms instantly into a carpet of soft roots and lichen, splashing onto the roofs of cars, sending seedpods from wildflowers and pollinating plants down in drifts along the New York sidewalks. Should a substance that fertile be developed in real life, Alamaro's—and Iceland's—plans could be realized in the blink of an eye.

In any case, will Alamaro finally succeed? Will we see whole new woodsy landscapes grow in the wake of sustained rural bombing campaigns—druidic warfare—cryptoforests spreading out from craters and abandoned fields far below? Will we launch seed grenades from sapling artillery, plant improvised explosive devices packed dense with forest nutrients?

City Turkey

In honor of US Thanksgiving, a snapshot stories about of the urban turkey.  As habitat shrinks due to the spreading of cities, urban turkey's much like their more domesticated brethren, the urban chicken, has begun to move to the cities (many stories such as here, here, and here) and develop a certain air of cosmopolitanism.

:: image via Boston Globe

As you can see, they have learned to assimilate to certain city rules in order to improve survivability.

:: image via Weather Underground

Sometimes, when a bright eyed newcomer isn't familiar with these customs, conflicts can arise.  From the USA Today, 'Booming turkey population ruffling feathers in urban communities' the explosion of turkey populations has inflitrated cities, such as this interloper in Cleveland: "A wild turkey holds up traffic on April 2 near Cleveland, Ohio. An animal warden was able to lure the turkey off the street to safety."

:: image via USA Today

Pittsburgh turkeys seem to occupy the green open spaces in neighborhoods (sort of a more suburban oriented breed).  In 'Turkeys turning into new pest on neighborhood block' showed that although docile, sometimes around Thanksgiving the birds can get surly: "Wild turkeys are not dangerous, but they do have occasional aggression issues. Last June the Pennsylvania Game Commission was called to Panther Hollow in Oakland, where wild turkeys were attacking bicycle riders. There were no reports of injuries to people."


:: image via Post-Gazette

The impacts of these new visitors can be both welcome and disdained, sort of reminiscent of the 'second-rate urbanism' necessary to not ruin the urban ideal.  These laid-back urban birds, being coddled by the locals, are from Eugene, Oregon:  "The local wild turkey population in urban areas has ballooned in recent years, but this is a case of turkeys, turkeys everywhere, but not a bird to eat. Visit the south hills of Eugene and you'll likely see them: wild turkeys in flocks, plucking berries, crossing streets, just hanging out. "Chris Yee of the Oregon Department of Fish and Wildlife says the problem won't stop until people stop feeding wildlife. Yee says turkeys normal habitat is 4 square miles but, "When fed inside the city limits they can limit their use to one or 2 square blocks in a residential area."


Lest we worry about being over-run by the 'farm-grown' varieties, you see the adaptations of the native turkeys (the one to the left, sort of bad ass looking, and reading for blending into the urban realm) the heritage varieties, which have maintained their native camoflague, versus the wimpy, white varieties who are woefully ill-equipped for the urban environment, and will likely end up on somebodies table - sort of a short trip from field to fork.

Happy Thanksgiving!

Aquifers not Aquitards

From the recent post on watershed boundaries, a reader mentioned the concept of underground aquifers and their relation to geographical boundaries and .  My title is in jest (sort of) referring to 'Aquitards' which according to Wikipedia is "a zone within the earth that restricts the flow of groundwater from one aquifer to another", but I thought an apt metaphor for our overuse and depletion of these amazing resources.  So in a crude analysis, the map of US aquifers is pretty amazing (here's a comparison of 'watersheds' and 'aquifers' in two maps with some context of states and cities (images from National Atlas mapping tool)

aquifers

watersheds

While many aquifers develop in tandem with surface waterways, others are disconnected from these sources giving them different patterns.  Ancient sources are often tapped, with draw-down causing these to be depleted much faster than they are recharged.  One of the most familiar, the 10 million+ year old Ogallala Aquifer (synonymous with 'High Plains Aquifer') that supplies water to the agricultural bread-basket of the world - centered in Nebraska and spreading from the southern tip of South Dakota into the northern panhandle of Texas.  


:: image via Wikipedia

I hadn't considered the number of aquifers and their distribution (another great tool is an online mapping application from National Atlas, found here), but it's interesting to see the difference between more broadly based, central aquifers (not specifically linked to a river) like the Ogallala, or in Oregon the Pacific Northwest Basaltic rock aquifers (unlike the Columbia River based systems to the north.  These more agriculturally oriented aquifers can be compared to small scale aquifers like the Biscayne which supplies drinking water to much of Central Florida.

:: image via USGS

The interactive mapper allows you to zoom in on state & county boundaries, as well as locations of significant cities, to see the relationship of urban agglomeration to aquifers, for instance a closer look at the area centered on Chicago (mapped from the National Atlas).


The cause and effect of cities and aquifers is probably more significant in the impacts of urbanization on water supplies (both through depletion and pollution) and the delicate interaction between surface and subsurface conditions.

:: image via Wikipedia

While subsurface conditions do exist separate from visible surface conditions, there are impacts as many rivers as charged with these underground sources, and depletion (and diversion) has caused some rivers to no longer reach the oceans - such as the Rio Grande and the Colorado (anyone guess the reasons) or the filling of traditionally large reservoirs like Lake Mead and Powell - creating significant water scarcity issues in certain metropolitan regions.  Another great lens to look at cities, so more on this to come... seems the hydrological cycle is tied to everything we do.

Natural Boundary / Political Boundary

I'm really glad that Strange Maps featured the interesting (albeit never realized) notion of John Wesley Powell's watershed-based approach to defining political boundaries in his 1890 'Map of the Arid Region of the United States'.  The concept reframes the Jeffersonian national grid, using drainage districts as "the essential units of government, either as states or as watershed commonwealths".

:: image via Strange Maps

Some further information: "Powell was convinced that only a small fraction of the American West was suitable for agriculture (3). His Report proposed irrigation systems fed by a multitude of small dams (instead of the few huge ones in operation today) and state borders based on watershed areas. The bulk of the arid regions should be reserved for conservation and low-intensity grazing. But other interests were at work; the railway companies lobbied for large-scale settlement and agricultural development."


:: image via Strange Maps

Just imagine the differing political geography of a West that is defined through natural boundaries of topography and hydrology, and what implications  While Powell's emphasis was on agriculture, imagine the different ways this would have allowed for looking at urbanization in the relatively dryland west that would have resulted through looking at availability of water.  Would Los Angeles and Phoenix be the same as they are today?

:: image via MIT

The concept obviously was a radically different approach to the orthagonally based, Jeffersonian approach in the late 18th Century, now continued to be managed by the Bureau of Land Management through the Public Land Survey System (a good resource of info as well from from National Atlas).

:: image via National Atlas
Some pertinent history, from the site:  "Originally proposed by Thomas Jefferson, the PLSS began shortly after the Revolutionary War, when the Federal government became responsible for large areas west of the thirteen original colonies. The government wished both to distribute land to Revolutionary War soldiers in reward for their service, as well as to sell land as a way of raising money for the nation. Before this could happen, the land needed to be surveyed.  The Land Ordinance of 1785 which provided for the systematic survey and monumentation of public domain lands, and the Northwest Ordinance of 1787which established a rectangular survey system designed to facilitate the transfer of Federal lands to private citizens, were the beginning of the PLSS."
The remnant of this being the rather 'straight-edge' development of political boundaries for delineating terrain that we live with today - the only diversions being for river edges that divide states, mostly expressed in the Montana/Idaho and somewhat less in the Washington/Oregon borders.

:: image via National Atlas

Drilling down into some of the smaller scale patterns, it's easy to see the disconnect between the political 'grid' and the underlying hydrology at work.  A map of Kent County Michigan (although not of the west) illustrates this point, with the clash of political delineation over the organic, dendritic patterning of hydrology on the landscape.

:: image via Wikipedia

Which maybe reads a bit different in a drier region, such as that of agricultural Kansas (where the use of fixed pivot irrigation is evident).

:: image via Wikiipedia

My favorite example of course, growing up in North Dakota where one is intimately connected to the Jeffersonian grid, is the use of the 6x6 mile township system dividing land into an individual square mile pattern to develop a road system that literally etches gravel pathways throughout every corner of the state (allowing a significant amount of public access to territory via ca, ostensibly for access to farmland).  It's virtually possible to zig-zag your way from one end of the state to another.  It's also interesting to note, even with a seemingly barren flat landscape, the subtle patterns of water (creeks and potholes) on the land (more on this later as I sat staring at Google Earth closeups for about an hour, mesmerized).

:: image via Google Maps

The grid of course, cannot stay pure (even in the topographically flat areas), and it's funny after miles of arrow straight country roads to encounter the grid shift (scene of many a lonely automotive faux pas on a snowy day).  These shifts, beyond the topographic, offer a more telling idea of the difficulties of a grid as a pure form on the larger landscape.

:: image via Google Maps

This idea, in a different scale, was inspirational for the conceptualizing of 'Neighborsheds' or neighborhood-based watersheds - that was the topic of my ASLA National Conference talk in 2006.  More on this soon, once I dig out the materials - something I've wanted to revisit.  Thanks to John Wesley Powell, although unsuccessful, in planting a seed of bioregional planning and boundary making, well before it was popular.

Simon Sadler: The Situationist City (1999)



Discussed by Christina Gregoriou

The author of the Situationist City, Simon Sadler was born in 1969 West Midlands. He is a Proffessor in Architecture and Urban History at the Universtiy of California, Davis and formerly a lecturer in Architectural History at the University of Nottingham. This book was intended to extract the Situationist architectural theory from a revolutionary program that attempted to confront the ideological totality of the Western world. The aim of the book was to search for the situationist city among the manifestoes, and works of art that the Situationists have left behind. Sadler focused on the early situationist program to try and save it as he says ’from the obscurity to which it was later on banished by the Situationist International.’

The Situationists were a group of revolutionaries influenced by the artistic avant-garde groups of the time. Early situationism was formed in 1957. The principle group and journals that formed Situationist International originated from two main lines: The expressionist groups of COBRA, and the International Movement of an Imaginist Bauhaus (IMIB) and the conceptual groups of the Lettrist and Lettrist International.


The Naked City

At the first part of the book, The Naked City, Sadler take us through the Situationisms’ critique of the environment as it currently existed. The Situationists were affected by the writings of thinkers like Henri Lefebre and Michael De Certeau who explored the principle of everydayness. They developed an awareness of the social structuring of the city into self-contained distinct quarters, of the city based on class occupation and function, but yet reliant on other components of the urban machine. Sociology implied this traditional planning that had grown under a rationalist umbrella, had reduced city structuring into a misleading, simplistic level.

Their experiments and case studies, analyzing the psychogeographical factors, influencing their mood, behavior and their choice of route as they were having their “drift” around the city. Each case study of the redevelopment of the naked city illustrated the situationist claims that urbanism represented a drive to rationalize, homogenize and commercialize Paris

An example of that is Debord’s and Jorn’s psychogeographical map where they cut up city street maps of Paris in a process of studying indigenous working class-zones. The map mourns the loss of old Paris, represents the city of the future, and explores the cities structures and use.
It serves as guides to areas of central Paris threatened for redevelopment, retaining those parts worth visiting, disposing of all those parts that they thought had been spoiled by capitalism.



Formulary for a New Urbanism

In the second part, Formulary for a New Urbanism, Sadler examines situationist principles for the city and city living The situationist city was a constant play of contrasts, between confined and open spaces, darkness and illumination, circulation and isolation. They described their drifts as radical rereadings of the city. They uncovered the social body of the naked city by ‘becoming streetwise’. They would explore discreet public gardens. The passages of the drifts were lined with cheap-shops and cafes; the guettos offered not only a different ambience, but also a non-bourgeois cost of living. Situationists would use their experience of language as a way of revolutionizing our consciousness of the city. Graffiti became regarded as a sign of the primitive energy of the everyday life of the masses. They even suggested the abolition of museums and the distribution of masterpieces to bars; believing that this would completely undermine cultural imperialism and elitism


New Babylon

In the third part, A New Babylon, Sadler described the closed situationists reached in making their ideas into reality; and that was through their proposal of the New Babylon. They ultimate goal was to reconstruct the city through a series of constructed situations. They assumed there was a ‘formulary’ that existed that would permit situations to be produced on demand. They claimed that each constructed situation would provide décor and ambience of such power that it would stimulate new sorts of behaviour, a glimpse into an improved future social life based upon human encounter and play. Sadler describes the Situationists' ideas of the Unitary Urbanism where it would no longer be driven by capital and bureaucracy, but by participation. It would be a unitary organism with different organs, dependent and inter-dependent on each other. In each experimental city, unitary urbanism was to act by way of a certain number of force fields, quarters. Each quarter would tend towards a specific harmony, divided off from neighbouring harmonies.

The Situationist International began to feel that unitary urbanism should not abandon the existing city in flavor of a virgin ground. That is why Constant’s New Babylon is shown suspended over entire cities and countries making literal Situationist International members', Debord and Jorn's, invocation in the pages of their Memoires of a ‘floating city’. In the structures that he proposed he would house some of the multiple functions that the traditional city accommodates individually. A typical sector in New Babylon could handle leisure, transport and shelter, addressing some of the situationist worries about the separation of activities by rational urbanism.

For the New Babylonians fun would not be a break from work and social normality. The principal activity of the inhabitants would be continuous drifts. They wanted to create that sort of disorientation, with changing landscapes from one hour to the next. The taste of the drift tends to promote all sorts of new forms of labyrinths made possible by modern techniques of production. Situationism tried to explore the concept that the accelerated movement and change of the city in the 20th century were incapable of relation to the pattern of a preexisting fabric. New Babylonians could physically rearrange the street they stood in. Every space is temporary, nothing is recognizable, everything changes, and nothing can serve as a landmark; the sense of labyrinth and disorientation that Constant wanted to emphasize that it could work supremely well as social space

At a later stage card holding members of the Situationist International comforted themselves that it was they, not ‘the technichian’ Constant who held the key to the effective use of those situationist ideas merely represented in New Babylon. After Constant left, he was denounced as a 'public relations man…integrating the massed into capitalist technological civilization’ with his ‘models of factories’.

After a few editions of the Situationist Interantional, they took an intensive critical turn that soon terminated their direct interest in Art & Urbanism, which also put Constant’s view of the Situationist City as the New Babylon out in the cold.
