In 2023, three already existing and protracted crises deteriorated to the point where the Inter-Agency Standing Committee (IASC) announced a system-wide scale-up (Democratic Republic of the Congo, Haiti, and Sudan). In each case, increasing Protection concerns were noted as key rationale for the new response posture. Across all three contexts, increasing reports of gender-based violence (GBV) were a trigger for scale-up, with actors across the humanitarian system raising alarms about GBV both before and after scale-ups have gone into place.
