Early Warning Systems are vital components of disaster risk management and the resilience of health systems, providing local stakeholders—governments, service providers, and communities—with the necessary information and time to prepare for and respond quickly to disasters and other hazardous events. As part of its efforts to build health resilience, MOMENTUM Integrated Health Resilience conducted a rapid assessment of existing early warning systems (EWS) in the Democratic Republic of the Congo (DRC), Mali, Niger and South Sudan. The assessment evaluated current EWS capabilities and provided recommendations for strengthening these systems to improve MNCH/FP/RH outcomes.
