As senior advisor of climate resilient water systems, Maurice Hall oversees Environmental Defense Fund’s work to manage groundwater more sustainably and revitalize working rivers and their ability to provide a resilient water supply. He focuses on developing collaborative water management approaches to meet ecosystem needs alongside the needs of farms and cities. Approaches central to this work include shaping water transaction programs that achieve resilient water supplies while protecting the environment and vulnerable communities, improving information systems to inform smart management of water resources, and shaping water governance that proactively considers multiple objectives and responds to climate change.
