Mumbai is in the midst of dramatic transformations. The juxtaposition of the awe-inspiring and heartrending sensations and physical realities is incredibly powerful. The brutality of change in the city forces one to confront new modes of urbanism and urbanisation. The urbanists and planner has the job to re-think, re-visit and re-learn means for intervention. Social, economic and political forces are reflected in an evolving urban form and local architects and planners are struggling to qualitatively intervene. The first essays in this book are extremely pertinent in their questioning of the status quo and the current mode of city-building. The third part of the book is about hope: which is to be found in the margins. The impossibilities of Mumbai are obvious, the stimulating forms of urbanity are in the margins were they provide clues for possible future interventions.
