Boundary thinking in landscape architecture and boundary-spanning roles of landscape architects

Abstract

Landscape architects play important roles in addressing societal challenges. To successfully address these challenges, this essay argues that they need to expand their understanding of boundaries and engage in boundary thinking. Distinguishing between physical, mental and socially constructed boundaries, we characterise boundary thinking as a creative process and productive motive in designing landscapes. Subsequently, we present four types of boundary-spanning roles for landscape architects to perform—the subject-based designer, the visionary narrator, the process-based designer, and the design-led entrepreneur—and point to the cognitive and social capacities needed to play any of these roles. We propose for landscape architecture to consider boundary thinking in agenda setting discourses and to include boundary spanning into practice. We suggest three avenues to pursue in realising professional opportunities: exploring the roles landscape architects play, understanding the environment that enables boundary-spanning work, and developing boundary theory in landscape architectural research
