Cities face a wide range of challenges affecting water supply, including climate change, increasing water demand, ageing infrastructure, rapid urbanization and economic development needs. One study estimates that by 2050, nearly one-half of the world’s urban population will face water scarcity.

To confront these challenges, water authorities must identify solutions to ensure water security and foster an ability to withstand or recover quickly from shocks. While higher-income countries have proven able to increase urban water resilience, lower- and middle-income countries (LMICs) face greater constraints in achieving this goal.

This study analyzes the literature on the common decision-making frameworks that guide such work across the globe and makes recommendations on how less-resourced cities and countries can protect their drinking water supply.
