Ibid. (Ibidem), the Latin acceptation for In the same place, is the metaphor that the book uses to explain the paradigm shift from the eviction and relocation approach towards 'on-site' or 'in-the-same-place' urban renewal and regeneration processes applied to the informal and low-income settlements. In the current scenario of economic and housing production crisis, greater social involvement, and where it is anticipated that urban development will mainly happen in cities, we confront a number of challenges concerning human settlements and their planning. Based on these arguments, the sole provision of housing by urban programs becomes inappropriate and insu cient. This book addresses the systemic approach to 'on-site' strategies as one of the essential changes in the urban renewal policies towards more resilient, sustainable, and integrated neighborhoods."
