This report provides guidance to policy and decision makers on holistic approaches to resilient services for water supply and sanitation (WSS) in the Caribbean, a high-risk region that struggles to manage natural disasters and other periodic shocks. WSS services are critical for societies everywhere. They should be predictable, robust, and able to come back online quickly following a disaster or shock. However, WSS services in the Caribbean are particularly vulnerable to shocks. Sea-level rise, land-use changes, demographic shifts, pandemics, and other factors can hamper service delivery throughout the region. To increase resilience in the sector, a water service provider needs to identify the threats and vulnerabilities and address those posing the greatest risks.
