Urban Colloquium 2 carefully explores the interconnected relationships between human communities, the built environment, and ecological systems through the lens of design and environmental justice. The course examines how urban systems—such as infrastructure, transportation, energy, and public space—are both shaped by and shape social, political, and environmental dynamics.Special emphasis is placed on how design practices can address climate change, environmental degradation, and urban inequality, while centering the needs and voices of frontline communities. Through interdisciplinary readings, case studies, guest lectures, and critical discussions, students engage with topics such as sustainable urbanism, green infrastructure, environmental racism, and the politics of resilience. The seminar encourages holistic thinking about the role of design in creating equitable, livable, and ecologically responsive cities. Students will develop critical perspectives and propose integrative strategies that bridge design, policy, activism, and environmental stewardship.
