As far as defining landscape urbanism, Shane mentions that the concept "has recently emerged as a rubric to describe the design strategies resulting in the wake of traditional urban forms.” (58) and echoes Waldheim in describing it as encompassing: "the practices of many designers for who landscape had replaced architectural form as the primary medium of citymaking. This understanding of decentralized post-industrial urban form highlighted the leftover void spaces of the city as potential commons.” (57-58) Furthering this defintiion that provides a way out of the current methodologies of urban design practice.
“Landscape urbanists want to continue the search for a new basis of a performative urbanism that emerges from the bottom up, geared to the technological and ecological realities of the postindustrial world… implies an opportunity open urban design out beyond the current rigid and polarized situation to a world where the past building systems and landscape can be included as systems within urban design.” (65)Shane mentions this in terms of creating new "recombinations and hybridizations, liberating the urban design discipline from the current, hopeless, binary opposition of past and present, town and country, in and out." (65) but does mention that although filled with potential as noted above, "All of landscape urbanism’s triumphs so far have been in such marginal and ‘unbuilt’ locations.” (62) This is another common refrain from critics of landscape urbanism, and it is worth noting that the ideas of contemporary urbanism and its potential solutions are very different in distant open spaces as opposed to dense urban fabric, which is valid, but also misses the point that the theory is attempting to address this situation, not, as many posit, blindly accepting sprawl as a given and deciding to operate within the residual post-industrial or generic Koolhaasian fields of landscape within the periphery. Rather there is a residual fabric of corridors, edges, and other surfaces that can be re-engaged within this ideology.

The precise operational dynamic of works of landscape urbanism is one thing - but to move beyond this and think of ways in which the concepts that interweave into practice is a different approach altogether. The landscape urbanist project, if you would call it such, is addressing all of this (hence the term distiguished from the suburban), and Shane does explain that “The recent discourse surrounding landscape urbanism does not yet begin to address the issue of urban morphologies or the emergence of settlement patterns over time. The problems of this approach is its amnesia and blindness to preexisting structures, urban ecologies, and morphological patterns.” and concludes that “Landscape urbanists are just beginning to battle with the thorny issue of how dense urban forms emerge from landscape and how urban ecologies support performance spaces.” (63)
This essay is way to dense to capture in any detail, but does offer some thought provoking historical origins of theory spanning the last century. The change in urban form and dynamics through this time period are exp
ressed by 'decompression', evolving from the ideas of Post-Fordist modes of production, deindustrialization leading to shrinking cities, and the resultant postmodern organization that "became obvious in the 1990s with the proliferation of sprawling cities, gated enclaves, residential communities, megamalls, and theme parks.” (59)
This context of contemporary urbanism is best captured by the provocatively wonderful 'City as an Egg' diagram from Cedric Price, which contrast three city morphologies "traditional, dense, ‘hard-boiled egg’ city fixed in concentric rings of development… the ‘fried egg’ city, where railways stretched the city’s perimeter in accelerated linear space-time corridors out into the landscape, resulting in a star shape… and the postmodern ‘scrambled egg city,’ where everything is distributed evenly in small granules or pavilions across the landscape in a continuous network.” (64)

A wide array of projects are included as examples. Some are more obvious or oft-mentioned, such as the Parc de la Villette, Downsview, and Freshkills competitions, and also the East River Competition conducted by the Van Alen Institute. There are some new ones, includingWest Market Square by West 8 (1994) which is a space owned, maintained and programmed by the city, but " which is also free at times to be occupied by local people of all ages, under the surveillance of cameras and local police.” (60) marking a new example of heterotropic space. The New Town Competition entry from Koolhaas/OMA from 1987 is another precedent where the residential form is shaped by, in the words of Corner, "linear voids of nondevelopment." (60) hinting at the concept of privileged site over architectural form.
Other examples include the unbuilt Greenport Harborfront project in Long Island (1997), which is an example of “the concept of ‘performative’ urbanism based on preparing the setting for programmed and unprogrammed activities on common land.” (59) which is reflective of some of the later work from Field Operations as well. A built example of the idea, in a more architectural and site scale context, is the sculptural Osaka Ocean Liner Terminal by FOA, where the architects "turn the concept of the green roof into a dynamic, flowing, baroque parkland setting… Pier and park, two previously separate urban morphologies, are hybridized so as to become inseparable.” (65)

Shane references an even more extensive list of references, which provide some great historical precedents. Many of these cover basic historical urbanism, such as the work of Kostof (The City Shaped, The City Assembled), history of the Western/US landscape by Slater and Conzen, and early 20th century writings on garden cities from Howard and regionalism, specifically 'Cities in Evolution' by Patrick Geddes from 1915. Other writings include later writings of Lynch, Rowe, as well as McHarg's 'Design with Nature' and shifts to more contemporary discussions from Harvey and Soja for exploration of postmodern urbanism, writings from Guy Debord 'The Society of the Spectacle' from 1995 and the explorations by Garreau of the edge-city phenomenon from 1991.

A fundamental aspect discussed by Shane is the connection to landscape ecology, specifically the work of Forman (Landscape Mosaics) and Forman & Godron (Landscape Ecology) and mentioning that its strength "is the consideration of the geographical landscape and the ecological cause-effect network in the landscape.”(61) The connections of landscape ecology and its roots in Europe are important due to the differing relations between nature and culture (rather than just dealing with landscape sans humans). As Shane elaborates:
"European land management principles merged with post-Darwinian research on island biogeography and diversity to create a systematic methodology for studying ecological flows, local biospheres, and plant and species migrations conditioned by shifting climatic and environmental factors (including human settlements.” (61)
Finally, the essays captures some of the more recent writings tied closely to LU theory, mentioning 'Stalking Detroit' (2001), 'Mississippi Floods' by Mathur & da Cunha (2000), 'Reclaiming the American West' by Berger (2002), 'Sub-urbanism and the Art of Memory' by Marot (2003), and 'Recovering Landscape' edited by Corner and published in 1999 - which i would consider a close precedent to the currrent discussion. Stalking Detroit is also an important contribution, offering essays by Waldheim and Corner and provides context, within the prominent shrinking city model of Detroit for a changing city typology. "After Ford' by Schumacher and Rogner, “provides a most convincing explanation for the relation between modern urbanism and Fordist economic imperatives, as well as the surreal spectacle of decay and abandonment found today in many North American industrial cities.” (57)

The work in Stalking Detroit, although unbuilt, provides some examples of potential operational methods of landscape urbanism. One project discussed was Waldheim's 'Decamping Detroit', which illustrates a four stage process for recolonization of space in the shrinking city, including "Dislocation (disconnection of services); erasure (demolition and jumpstarting the native landscape ecology by dropping appropriate seeds from the air ); absorption (ecological reconstitution of part of the Zone with woods, marshes, and streams); and infiltration (the recolonization of the landscape with heteropic, villagelike enclaves.” (59)
This context of deindustrialization and surburban sprawl is a consistent theme, moving away by necessity from the modernist planning ideology and including a different reading of the city, focus on urban morphology, activated with new strains of thinking from landscape ecology with a goal, as explained by Shane: “A determination not to accept the readymade formulas of urban design, whether ‘New Urbanist’ or ‘generic’ urbanist megaforms a la Koolhaas.” (64) The key this is a reversal of normal processes, which "opens the way for a new hybrid urbanism, with dense clusters of activity and the reconstitution of the natural ecology, starting a more ecologically balanced, inner-city urban form in the void.”(59)
Check out as well a longer version of this article from the Harvard Design Magazine (pdf) and I would highly recommend 'Recombinant Urbanism' from 2005 for an exhaustive study of urban modelling processes.
