This social involvement course is engaged with questions of democracy in spatial planning, and includes theoretical learning, guest lectures and group researching. We will focus on a new application now developed by social activists for on-line mapping of planning schemes and urban mobilizations, on the activity of planning NGOs, and on planning communications in news-media and the social media. Theoretically- we will learn several different concepts of justice, dealing with fair social and environmental distribution, with the ethics of democratic planning procedures and with recognition in complex societies. We will connect these thesis to questions of participation and partnership,  centrality and marginality, and to the new prospects brought by the new modes of on- line mapping. Each group of students will practice and contribute in a thematic study of one of the course themes. To sum- the groups will present and discuss their findings in class.
