Whether explicit or not, all activities of landscape architecture are guided by socially-constructed values with short-term as well as long-term impacts.Landscape values are web-like, mutable and constantly shifting.This paper offers a brief reflection and literature review on the role of landscape values as drivers of change in terms of landscape development; resource allocation; land ethics and perception; and design theory.As anticipatory professionals, perhaps the most important role of landscape architects is to forecast the values of the future, mediate them against the values of the present, and to lay the groundwork so that a trajectory between them becomes possible.The expertise that best distinguishes landscape architects from other professionals therefore is the capacity to conduct comprehensive and balanced analysis of alternative value systems, to produce clear visualizations of their consequential trade-offs, and to identify strategies that lead society toward more sustainable and satisfying outcomes.
