Turning Brownfield Sites into Sustainable Urban Landscapes: A Redevelopment Framework The Case of National Steel Corporation in Southern Philippines

This paper investigates the sustainable redevelopment of defunct industrial sites, with a focus on the National Steel Corporation (NSC) in Iligan City, Philippines. The study aims to develop a framework for transforming post-industrial landscapes into productive, environmentally sound, and community-integrated spaces. Utilizing a mixed-methods approach, data were gathered through desk research, site assessments, key informant interviews, surveys, and document analysis. Findings reveal that successful redevelopment hinges on inclusive stakeholder engagement, phased environmental remediation, and the integration of green infrastructure. The proposed framework emphasizes adaptive reuse, socio-economic integration, and long-term ecological resilience. This research contributes to urban planning practices by providing practical strategies in converting obsolete industrial land into sustainable urban landscape.
