Landscape Urbanism is a theory of urban planning arguing that the best way to organise cities is through the design of the city's landscape, rather than the design of its buildings. 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'. From the late 1990s, the phrase was used in the United States by landscape architects to refer to 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 commercialised, multi-phase urban parks, such as Olympic park design.
The first majors 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 University of Pennsylvania in the late 1980s, at a time when 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 Oslo School of Architecture , Catholic University in Leuven, Belgium , the University of Illinois at Chicago, the University of Toronto, Harvard Graduate School of Design, and Massachusetts Institute of Technology . In 2000 the London's Architectural Association developed its own Landscape Urbanism program under the direction of Ciro Najle and chairman at the time Mohsen Mostafavi. This was marked by the 2003 publication of the book "Landscape Urbanism: A Manual for the Machinic Landscape" a year before chairman Mostafavi left the AA.
James Corner is the author of an essay entitled "Terra Fluxus." He has identified five general ideas that are important for use in Landscape Urbanism. They are as follows:
- Horizontality - The use of horizontal alignment in landscaping, rather than relying on vertical structuring.
- Infrastructures - placing less of an emphasis on urban infrastructures that have been traditionally used, such as roads and airports, and instead relying on a more organic use of infrastructure.
- Techniques - those who practice the idea of landscape urbanism should be able to adapt their techniques to the environment that they are in.
- Ecology - the idea that our lives intertwine with the environment around us, and we should therefore respect this when creating an urban environment.
The following are Landscape Urbanism projects that are available that can provide more information about the theory in practice:

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 nework.
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 infrastructure. The artificial ecology replaces the entropic state to re-create a "natural" 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." 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; and the yet to be constructed Project Phoenix  in Haiti.
In an extended discussion the Urban Landscape System has been proposed as a more comprehensive approach, which opens Landscape Urbanism to the field of Urban Ecology.
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'.
