Water security is one of the most pressing challenges for India’s cities, towns, and villages in the 21st century, especially in rapidly growing megacities like Bengaluru. This volume explores how the IIHS Kengeri Campus serves as a living laboratory for testing and implementing systemic water management solutions that address climate change, water scarcity, and pollution. Drawing on historical water-resilient city designs—from Hampi to Istanbul and New York—this book examines the shift from traditional water systems to centralized supply models and their consequences. It highlights how innovative, scalable interventions in sustainable water use, conservation, and urban resilience can shape a more water-secure future for Bengaluru and beyond.
