Complex emergency
Definition
A complex emergency is defined by the UN Inter-Agency Standing Committee (1994) as a humanitarian crisis in a country, region or society where there is a total or considerable breakdown of authority resulting from internal or external conflict, requiring an international response beyond the mandate or capacity of any single agency or ongoing UN country programme. Typical features include extensive violence and loss of life, displacement, and widespread damage to societies and economies.

Overview
What it means
The term distinguishes crises driven by political breakdown and conflict from purely natural disasters — and many emergencies now combine both.
How it is used
UN OCHA uses the designation to trigger coordination mechanisms such as the cluster system, special appeals and multi-agency information management.
Why it matters
Most large, protracted humanitarian crises today are complex emergencies, increasingly compounded by climate shocks.
