Megacities, Megathirst

This lecture explores the challenges faced by megacities in terms of water resources, focusing on the impact of urbanization on the water cycle, the need for water budget tools, and the consequences of overpumping groundwater. Case studies from cities like Mexico City, Los Angeles, Dubai, and Beijing illustrate the issues of water scarcity, aquifer depletion, and the importation of water. The lecture also discusses the importance of new governance strategies and technical innovations to address these water-related challenges.
