About this book:

*Madras Environmental History: Coastlines, Canals, and Urban Ecology* provides a comprehensive longitudinal study of how the city of Chennai was constructed through the manipulation of its unique littoral landscape. The book moves from the precolonial era—characterized by an "infrastructural culture" of interconnected lakes (*eris*) and wetlands—to the colonial period, which introduced large-scale engineering projects like the Buckingham Canal. It details how the British and subsequent post-independence administrations reconfigured the Cooum and Adyar rivers into urban drains, reclaimed vast marshes for real estate, and hardened the shoreline for industrial ports, effectively trading natural flood buffers for urban expansion.

The narrative highlights the severe ecological and social consequences of these transformations, particularly the degradation of the Pallikaranai wetland and the marginalization of traditional fishing communities. As the city transitioned into a modern metropolis, its "urban metabolism" demanded massive flows of sand, stone, and steel, while its growing population necessitated increasingly complex water supply strategies, from distant reservoirs to desalination. The text argues that the systematic filling of "wastelands" and the externalization of sewage have created a city highly vulnerable to the contemporary threats of cyclonic floods, extreme heat, and rising sea levels.

A significant portion of the book focuses on the emergence of environmental governance, tracing the evolution of coastal regulations (CRZ) and the role of GIS and remote sensing in monitoring change. It underscores a growing tension between top-down public works and bottom-up citizen advocacy, where the judiciary and grassroots movements have become essential in fighting for environmental justice and the protection of the commons. The author emphasizes that the risks of climate change are not evenly distributed, with residents of informal settlements bearing the brunt of historical planning failures and industrial pollution.

Ultimately, the book concludes with a call for a paradigm shift toward "designing with water." By analyzing successful case studies in ecological restoration—such as the Adyar Creek Eco-Park—it proposes a future where Chennai functions as a "sponge city." This vision requires a move away from combative engineering and toward the integration of green-blue infrastructure, suggesting that the city's long-term resilience depends on its ability to respect and restore the natural hydrological systems that originally defined the Coromandel Coast.

What You'll Find Inside:

• Traces Madras/Chennai's ecological evolution from pre-colonial wetland systems (eris/tanks, marshes, backwaters) through colonial canal infrastructure to modern urbanization, revealing how water management shifted from adaptive community practices to top-down engineering.
• Examines the degradation of the Cooum and Adyar rivers from sacred waterways to polluted drains, while documenting restoration successes like Pallikaranai marsh and Adyar Creek that demonstrate ecological recovery potential.
• Analyzes how land reclamation, industrialization (especially in Ennore), and coastal modifications created environmental vulnerabilities and disproportionately burdened marginalized communities, including fishing villages and informal settlements.
• Explores contemporary challenges including climate change impacts (sea-level rise, heat, salinity), flood risks from historical wetland loss, and water security struggles despite reservoirs, inter-basin transfers, and desalination plants.
• Advocates for a 'designing with water' approach integrating green-blue infrastructure, restoring natural hydrological processes, and learning from historical water management to build a resilient, equitable, climate-ready littoral city.

Who's It For:

This book is written for environmental historians, urban ecologists, and city planners seeking historical context for contemporary urban environmental challenges. It will particularly benefit professionals in coastal management, water infrastructure, and urban resilience planning who need to understand how ecological processes and political economies co-produce urban landscapes. Researchers, students, and practitioners working on environmental justice, climate adaptation, and sustainable urban development in coastal cities will find valuable insights in its interdisciplinary approach combining archival research, cartography, remote sensing, and policy analysis.
