Water risks, including the lack of access to fresh water for personal and industrial use, droughts, floods, and water contamination, are problems that are not new, yet, they are amplifying in the face of climate change, population growth, and rapid economic development. Properly identifying, measuring, and managing these risks as well as taking advantage of related mitigation opportunities is essential for the future well-being of firms across various industries, investors who invest in these firms, local and federal governments, and ultimately our society as a whole. This edited book sheds light on this topic by examining the unique measurement and modelling challenges associated with either the scarcity or overabundance of water and their interaction with finance and society. Specifically, it explores approaches to assess and operationalize water risk, examines the vulnerability of institutions and markets, and discusses strategies for risk mitigation.
