"The river city book genre is experiencing a boom. Da Cunha's book, however, is more primordial. It is hat rare combination of imagination, originality, and historic and theoretical rigour. It is the culmination of intensely methodical, patient, and attentive work of design research; often conjured, but seldom delivered to its full promise, as it is wonderfully here. The Invention of Rivers is an essential historical contribution to our future. It dares us to move toward an aspirational postcolonial moment of 'after rivers,' when they are returned, epistemologically and methodologically, to wetness. Where the Ganga's Descent transforms from the locks of Shiva's hair in river into the 'infinite strands of each individual hair' in the form of rain. In the midst of global existential climate flux, I cannot think of a more compelling, urgent challenge." (Planning Perspectives) "The Invention of Rivers is a radical and timely book that will stimulate considerable debate on matters of the greatest contemporary urgency." (Arjun Appadurai, New York University) "A highly original argument and extraordinary piece of scholarship that comes at a time when rain is behaving unpredictably and challenging humanity's attempt to contain it within banks. It offers an alternative way of thinking about our relationship with the hydrological cycle and of living with wetness." (Lindsay Bremner, University of Westminster)
