IASC’s “cluster approach” to humanitarian assistance

The “cluster approach” to humanitarian assistance aims to strengthen humanitarian response by ensuring high standards of predictability, accountability and partnership. Any major new or ongoing emergency is addressed in terms of the following clusters, each with its own lead agency or agencies, and a range of UN and non-UN partners:

The Office of the High Commissioner for Human Rights (OHCHR) is also part of the IASC. 

In a given country, upon the occurrence of a complex emergency or when an already existing humanitarian situation worsens in degree or complexity, the UN Emergency Relief Coordinator, on behalf of the Secretary-General and after consultation with the IASC, designates a Humanitarian Coordinator for that country.

OCHA also helps its IASC partners and the humanitarian coordinator to mobilize resources by launching consolidated inter-agency appeals.
