This study explores the critical yet underrecognized role of Landscape Architects in navigating complex socio-political and ecological issues. Despite their unique interdisciplinary skill set—encompassing art, ecology, engineering, climate, and sociology—Landscape Architects are often overlooked in public discourse and planning. To challenge this dynamic, the author investigates whether active engagement in political-economic arenas can amplify the impact of landscape architecture. The test case is the Belchertown State School in Massachusetts, a 600-acre mental health facility in the process of deinstitutionalization. With no clear post-closure plan and conflicting stakeholder interests between local government and the New England Small Farms Institute—the site became a contested landscape. Through active participation, the project examined how landscape architectural thinking could mediate land use conflicts, reveal underappreciated assets, and foster visionary reuse of a vast and underutilized public resource. The case study illustrates how Landscape Architects can serve as effective political agents in shaping more inclusive, sustainable outcomes.
