This handbook provides a comprehensive, state of the art overview of urban water governance. It addresses the key questions of how urban water governance works, how is it shaped and what the impacts are.

Thomas Bolognesi is a researcher at the Geneva School of Business Administration, HES-SO. His research investigates the processes of social-ecological systems evolution, emphasizing non-linearities and patterns diversity. He combines economics and public policy analysis to study the organization and effects of urban water services regulation, the development of water policy regimes, and water security.

Francisco Silva Pinto is an Assistant Professor at Lusofona University (LU) and researcher at EIGeS, FE-LU, and CERIS, IST-UL. His research interests cover the application of numerical modelling and analytics to support decision making in governance, pricing, and finance of utilities (mainly water supply, wastewater, and waste) under critical socio-economic and environmental situations.

Megan Farrelly is an Associate Professor in the School of Social Sciences at Monash University. Her research explores the intersection of urban water governance and sustainability transitions, focusing on processes and pathways for delivering practical and socio-institutional change towards sustainable urban transformations.
