Landscapes are not fully explainable by the axioms of any single system of signification. Landscape architectural theory, largely based either on art historical models (which exclude ecological thinking) or environmental models (which exclude the visual and spatial representations of culture) has not produced or applied, until the present moment, a framework adequate to describe the profound complexity inherent in landscapes, precisely because landscapes embody, at once, culture and nature, art and science, the collective and the personal, the natural and the artificial, the static and the dynamic. In this presentation I will examine how contemporary landscape practices, primarily those that draw from systems theory, allows us to cut across the schism sustained by the exclusionary effects of traditional theories, and to reinterpret concepts of site, place, and landscape in ways that allow for their reconceptualization as processes, practices, and places that have functional and metaphorical multiplicity.
