Well,
not all agriculture requires lots of sun.
As apart from urban design proposals such as New Urbanism and some of the so-called "green" architecture being designed by experimental design offices, semi-urban farms like these do not propose a bright and new future where environmental problems spur fantastic Disney-like living, and nor do they suggest, as in the case of New Urbanism, a over-dependence on historical precedent to solve design problems. Instead, a project like the above becomes viable through its novel and creative use of the infrastructural landscape (in this case, an abandoned infrastructural landscape) which is by far the most dominant type of landscape in the modern human world: urban centers are not just busy streets, markets, and high-rises, and nor are they dominated mainly by suburban sprawl. Any urban center is fed by a network of support mechanisms that extend far beyond anywhere we would call the "city". After all, Chicago's treated sewage effluent
eventually finds itself in the Gulf of Mexic. It is this
infra-structure
that provides opportunities for new adaptations of agricultural production - production that has generally been assumed to be somehow totally dependent upon the rural landscape. Even in the usual proposals for urban-agriculture, rural and somewhat pastoral surfaces are zoned, demarcated, and often decontaminated, apart from the unwanted city, in an effort to "restore" open space that is often considered to be a pre-requisite for the growth of food and of a new "post-industrial" urban reality. But really, there are forms of agriculture that depend on nothing but the urban and industrial / infrastructural landscape, and we should take advantage of them.
True, this specific example is one of the re-use of an
abandoned infrastructure (or so called abandoned infrastructure), but it forms in a way its own linkage to the city that could not have come about without the realities of industry and its support networks. And in an energy-scarce world where food production will need to be re-introduced as a visible and highly activated center of urban life, it's worth considering embracing infrastructure as a medium on which to construct the future city.
