PERSISTENT VISUAL STIMULATION

Rivers and fields contribute to persistent visual stimulation, a characteristic of productive urban landscapes. In some cases direct relationships exist between spaces with different temporal rhythms, for example a river, with its frequent sur­face undulations reflecting a dappled light, and a gentle sound, seen against the slower rhythms of crop lifecycles.

The arrangement of furrows and beds for planting, which are found in typical urban agriculture sites and market gardens the world over, echo ancient patterns of spatial divisions, found in nature and agriculture (see Plate 16). The artist Tom Phillips, has speculated that primal marks found in the natu­ral landscape, for example line, point, and hatch, as well as characteristics such as branching, forking, repetition, and variation, provide a basic visual grammar and syntax, from which ornament has been derived (Phillips, 2003). The same words used by Tom Phillips to describe the natural envi­ronment can be used to describe the conditions found in urban agriculture fields. Continuing this train of thought it can be argued that the appeal of agricultural landscapes derives from an ancient understanding of the marks they make in the land­scape, which can be read as an elemental form of ornament. Thus, urban agriculture in particular can be read as a deeply understood form of ornament within the city. Through urban agriculture it is possi­ble to experience urban ornament.
