What happens when a distant colonial power tries to tame an unfamiliar terrain in the world's largest tidal delta? This history of dramatic ecological changes in the Bengal Delta from 1760 to 1920 involves land, water and humans, tracing the stories and struggles that link them together. Pushing beyond narratives of environmental decline, Bhattacharyya argues that 'property-thinking', a governing tool critical in making land and water discrete categories of bureaucratic and legal management, was at the heart of colonial urbanization and the technologies behind the draining of Calcutta. The story of ecological change is narrated alongside emergent practices of land speculation and transformation in colonial law. Bhattacharyya demonstrates how this history continues to shape our built environments with devastating consequences, as shown in the Bay of Bengal's receding coastline.

‘Debjani Bhattacharyya resurrects Calcutta's forgotten watery origins to recuperate an entirely riveting account of the city and its real estate market. The book shows how the fictitious capital of property value relies on an enduring amnesia about the intractable and transient texture of ecological landscapes. Deeply researched and brilliantly conceived, it offers a path-breaking account of the urban ecological crisis and its uncertain future.'

‘In this fascinating study of the emergence of the metropolis of Calcutta out of the swampy landscape of the Bengal delta, Bhattacharyya shows how the production of a modern urban property regime entailed a forgotten transformation of the very earth upon which it was constructed.'

'Empire and Ecology has immense potential to shape conversations across a range of disciplinary and interdisciplinary concerns. … This is a book to keep ready to hand on shelves and to place prominently on syllabi.'

'Empire and Ecology in the Bengal Delta is path-breaking and makes a compelling case for drawing urban studies in South Asia into the deepening folds of environmental history. This is an original effort that brims with theoretical insights and helps us recover ways for 'remembering' contemporary Kolkata’s many entanglements with the Bengal delta’s soaking ecology.'

'In her innovative new book, Empire and Ecology in the Bengal Delta, Debjani Bhattacharyya, a professor of history at Drexel University, describes how Bengalis had their own story about Calcutta’s origins. 'Legend has it that the city was born when the ocean started churning, and a tortoise', pressed between the mountains and the force of Ananta, the infinite, 'gasped out a deep breath'. Its breath made the Bengal Delta, a vast 40,000 square mile area where the Ganges and Brahmaputra rivers seep into the Bay of Bengal. This legend … carries an element of truth: Calcutta rests on shifting ground. It should be no surprise that its fortunes have shifted too.'
