Urban Sustainability Versus Green-Washing-Fallacy and Reality of Urban Regeneration in Downtown Seoul

This paper examines the planning paradigm shift related to the contested urban renaissance mega-project in Downtown Seoul (Korea). Similar to other global cities, over the last few decades, different mega-projects have been successfully implemented in Seoul. These projects have been considered engines for urban renewals and transformation. This paper builds on the analysis of the failure and re-framing planning strategy for the Green Corridor (GC) mega-project, part of the Urban Renaissance Master Plan for Downtown Seoul. The GC case reveals various critical insights for urban sustainability: (i) the current mega-projects' sustainability fallacy, related to top-down, technocratic densification, and greening practices; and (ii) the untapped potential of Asian traditional and irregular small scale urban patterns, and their related socio-cultural value in addressing the renaissance of the long term urban sustainability. In particular, the discussed research findings point out that urban renaissance enabling sustainability principles requires integrated, small scale, incremental, and adaptive (stepwise) urban planning and design processes that go well beyond general strategies following the so-called green growth paradigm.
