Urban redevelopment projects - The doctorate students of the 13th edition of ‘Urban, territorial and environmental planning’ dealt with important theoretical questions concerning the redevelopment of abandoned and underused urban areas in the basic ‘Urban planning course’. The essays published here present three situations in which an examination is made of the main stages in the transformation of areas, the legislative instruments that were used, the objectives set by planners, the expected outcomes and the effects induced. The three cases are presented as examples although with different degrees of planning consistency and effectiveness: one clear case of success expected and achieved at Bercy (Paris); one case of circumscribed success, but with unplanned outcomes within the Pompeo Leoni area (Milan); one case of success, but with unsettling effects on the relationship with the surrounding urban context Jaffa (Israel).
