A cluster is a group of agencies that gather to work together towards common objectives within a particular sector of emergency response.
The cluster approach, instituted in 2006 as part of the UN Humanitarian Reform process, is an important step on the road to more effective humanitarian coordination. Ultimately the cluster approach aims to improve the predictability, timeliness, and effectiveness of humanitarian response, and pave the way for recovery. It strengthens leadership and accountability in key sectors. It also seeks to enhance partnerships and complementarity among the UN, Red Cross Movement, and non-governmental organizations (NGOs).
Through the provision of information management services and expertise, iMMAP Inc. is a full member of seven global humanitarian clusters: Health, WASH, Nutrition, Food Security, Protection, Logistics and Emergency Telecommunications.
