Landscape urbanism

From Wikipedia, the free encyclopedia

https://en.wikipedia.org/wiki/Landscape_urbanism 

Landscape urbanism is a theory of urban design arguing that the city is constructed of interconnected and ecologically rich horizontal field conditions, rather than the arrangement of objects and buildings. Landscape Urbanism, like Infrastructural Urbanism and Ecological Urbanism, emphasizes performance over pure aesthetics and utilizes systems-based thinking and design strategies. The phrase 'landscape urbanism' first appeared in the mid 1990s. Since this time, the phrase 'landscape urbanism' has taken on many different uses, but is most often cited as a postmodernist or post-postmodernist response to the "failings" of New Urbanism and the shift away from the comprehensive visions, and demands, for modern architecture and urban planning.

The phrase 'landscape urbanism' first appeared in the work of Peter Connolly, a Masters of Urban Design student from RMIT Melbourne. In 1994, Connolly used the phrase in the title for his Masters of Urban Design proposal at RMIT Melbourne. Here, he suggested that 'a language of "landscape urbanism" barely exists and needs articulating', and that 'existing urbanisms ... are limited in the exploration of the landscape'. He also used the term 'landscape as urbanism' in his 1994 essay, '101 Ideas About Big Parks'. In 1996 Tom Turner wrote that

The city of the future will be an infinite series of landscapes: psychological and physical, urban and rural, flowing apart and together. They will be mapped and planned for special purposes, with the results recorded in geographical information systems (GIS), which have the power to construct and retrieve innumerable plans, images and other records. Christopher Alexander was right: a city is not a tree. It is a landscape.

In the late 1990s, concepts of 'landscape urbanism' were often used by landscape architects in the United States in the re-organisation of declining post-industrial cities, such as Detroit. From the 2000s, it was used in Europe by architects to mean a highly flexible way of integrating large-scale infrastructure, housing and open space. By the late 2000s, the phrase became associated with highly commercialized, multi-phase urban parks, such as Olympic park design. Landscape urbanism strategies in the U.S. are now widely used in waterfront redevelopment, recapturing urban vacancy, urban agriculture, and green infrastructure. LU, EU, and IU strategies are rising in importance with growing concerns over climate change.

History

The first major event to do with 'landscape urbanism' was the Landscape Urbanism conference sponsored by the Graham Foundation in Chicago in April 1997. Speakers included Charles Waldheim, Mohsen Mostafavi, James Corner of James Corner/Field Operations, Alex Wall, and Adriaan Geuze of the firm West 8, among others. The formative period of Landscape Urbanism can be traced back to RMIT University and University of Pennsylvania in the late 1980s, at a time when Peter Connolly, Richard Weller, James Corner, Mohsen Mostafavi, and others were exploring the artificial boundaries of Landscape Architecture, Urban Design and Architecture, searching for better ways to deal with complex urban projects. However, their texts cite and synthesize the ideas of influential modernist methods, programmes and manifestoes that appeared in the early twentieth century. Charles Waldheim, Anu Mathur, Alan Berger, Chris Reed, amongst others, were students at the University of Pennsylvania during this formative period for Landscape Urbanism. After the Chicago conference, European design schools and North American design institutions formed academic programs and began to formalize a field of Landscape Urbanism studies, including the University of Toronto, Harvard Graduate School of Design, Oslo School of Architecture, Massachusetts Institute of Technology, Catholic University in Leuven, Belgium, the University of Illinois at Chicago, and London's Architectural Association. 

The development of an actual operative response to the broad and often vague concepts surrounding landscape urbanism was largely developed at the Architectural Association in London. Prior to this period of design exploration, landscape urbanism had never been clearly developed as an actual design practice. Today, much of the design culture that has come to be associated with landscape urbanism was initiated and developed in the AA Landscape Urbanism program during its early formative period and its influence persists in many educational institutions. A number of practices that have chosen to adopt the design and conceptual approach towards urbanism have also adopted many of these design strategies.

Themes

James Corner is the author of an essay entitled "Terra Fluxus." He has identified four general ideas that are important for use in Landscape Urbanism. They are as follows: 

1. Process over time - Understanding the fluid or changing nature of any environment and the processes that affect change over time. A respect for natural processes (Ecology) - the idea that our lives intertwine with the environment around us, and we should therefore respect this when creating an urban environment. Landscape Urbanism is concerned with a working surface over time – a type of urbanism that anticipates change, open endedness and negotiation.
2. Horizontality - The use of horizontal alignment in landscaping, rather than relying on vertical structuring.
3. Working Methods /Techniques - Those who practice the idea of landscape urbanism should be able to adapt their techniques to the environment that they are in.
4. The imaginary - That in many ways the failing of twentieth century planning can be attributed to the absolute impoverishment of the imagination to extend new relationships and sets of possibilities 

Ten characteristics

Tom Turner summarized the ten characteristics of landscape urbanism in the book Landscape design history and theory: landscape architecture and garden design origins:

1. Broad scale context: Landscape urbanism does not belong to a specific scale. It can be considered in small or large-scale projects.
2. Landscape is a context which contains architecture and civil engineering.
3. Landscape is seen as a third machinery arm that makes a connection between its components. Mohsen Mostafavi, the author of Landscape Urbanism : A Manual for the Machinic Landscape used the same phrase.
4. LU projects can provide the opportunity of increasing the social interactions. Also, Emily Talen, one of the writers of Landscape Urbanism and its Discontentes talks about social aspects of a LU project "by forming three theoretical alliances: one with post-structuralism, one with ecology, and one --peculiarly-- with Marxism."
5. Function is the most significant concern in LU machine, which gives the appearance of a project less importance.
6. LU discovers the potentials and opportunities in landscapes.
7. The infrastructure are highlighted in LU projects.
8. LU projects will develop the interrelationship between natural and engineered systems.
9. LU will break the boundary between the landscape and the city and will organize them as one.
10. The answer to the projects which are complex or have ecological concentrations, is landscape urbanism

Criticism

Landscape urbanism has been criticized as an idea that is only loosely defined from a set of flashy projects. These are expensive schemes with a commercial and esthetic purpose that satisfy a local or regional ambition to invest in ecology or sustainability without posing a more globally applicable approach. A true merger of landscape architecture with the field of Urban Ecology lacks. From this criticism Frederick Steiner introduced landscape ecological urbanism as an approach that can include the field of urban ecology and Wybe Kuitert has shown how such integrative planning and management of the city should rely on analysis. Discerning the potential quality of wild nature in the city is a first step to see how new urban ecology might be developed. Potential vegetation maps for a city are the tool to this end.

One opponent to Landscape Urbanism is New Urbanism, led by Andres Duany, which promotes walkable communities and smart growth with its Transit Oriented Development (TOD) and Traditional Neighborhood Design (TND). In response to landscape urbanism’s focus on expansive green space in urban development, Duany stated that “density and urbanism are not the same.” Further, “unless there is tremendous density, human beings will not walk.”  The result is patches of green sprawl that lose connectivity to the greater network. 

Emo Urbanism is another philosophy critical of Landscape Urbanism. The movement contends that Landscape Urbanism views ecology as an aesthetic element of style and not urban ecology. The artificial ecology replaces the entropic state to re-create a landscape that fits a particular brand or aesthetic. The loss is a dynamic, adaptive, and certainly essential urban system. Emo urbanism differs by making evolving "nature" a key component of the design process. The realization of this process is called “Urbanature" and "Big Nature." As an evolving urban ecology, Charles Morris Anderson has described this connection as the “thinness.” It is the simultaneous perception and implicit understanding of the past, present, and future. Emo Urbanist projects include the built work of Charles Anderson at the Olympic Sculpture Park in Seattle, WA; The Anchorage Museum Common in Anchorage, AK; the yet to be constructed Project Phoenix in Haiti and Hellinikon's Metropolitan Park in Athens, Greece. 

Ian Thompson has published a critical review of landscape urbanism in which he identifies its ten tenets and asks six critical questions. His conclusions are:

... there are ideas with the Landscape Urbanism discourse which have great merit, among which I would include the breaking down of professional distinctions, the integration of ecological thinking, the foregrounding of infrastructure, the interest in the positive use of waste materials and the emphasis upon functionality rather than mere appearance. There is also a quantity of dubious philosophy, unhelpful imagery and obscurantist language that Landscape Urbanism ought to dump. ... Larding the case for Landscape Urbanim with Deleuzian and Derridean references was a mistake, since it was done principally to impress an academic elite, and it has even left large sections of its intended audience bemused'.
