This project-based course offers an introduction to the urban practice by delving into current urban conditions of injustice or inequality and exploring progressive practices, as case studies, challenging similar issues. Learning from those experiences, students propose actionable strategies involving policy and design to promote transformative interventions. The course is divided in three phases; research/analysis, theoretical/practical enquiry and design strategies/action. In the first phase, using different methodologies, students will delve into pressing social, economic, environmental or spatial issues, such as school and housing overcrowding, vacant properties and homelessness, rezoning processes and displacement of low-income communities, challenges of non-speculative housing models and other urban realities affecting vulnerable populations. In the second phase, students will explore theoretical as well as practical approaches addressing such issues coming from those being affected as well as fighting against them such as activists, community groups, and practitioners. Finally, in the last phase, using the knowledge previously acquired, students will envision feasible scenarios and design strategies leading to urban processes and practices producing more equitable and just cities.
