The main idea is understanding how humanitarian coordination is organized in disasters. The cluster approach is a UN-led mechanism that groups actors by sector (health, shelter, water, etc.) to coordinate, standardize, and fill gaps in the response. This structure was created to bring coherence to diverse actors—donors, NGOs, and agencies—under a single coordinating framework, with the United Nations System providing the overarching leadership and the Office for the Coordination of Humanitarian Affairs guiding the process.

Even though a specific UN agency often leads a particular sector (for example, the Health cluster is commonly led by the World Health Organization), the overall leadership of the cluster system rests with the UN. The others listed play important roles within certain clusters or contexts, but they do not provide the global, cross-sector leadership of the cluster approach. The World Bank focuses on financing development rather than disaster response coordination, and the International Red Cross operates widely across clusters as a partner, not as the overall coordinator.
