As with the stock market, climate change requires a diversified portfolio of solutions. California Gov. Gavin Newsom recently signed an executive order to develop a comprehensive strategy for making the state’s water system climate-resilient. The order calls for a broad portfolio of collaborative strategies to deal with outdated water infrastructure, unsafe drinking water, flood risks and depleted groundwater aquifers.

In a related study published earlier this year, Stanford researchers Newsha Ajami and Patricia (Gonzales) Whitby examined effective strategies to rising water scarcity concerns. Ajami is director of Urban Water Policy at Stanford’s Water in the West program and a hydrologist specializing in sustainable water resource management.
