Background: The Cluster model is designed as a solution to promote humanitarian response management. This approach is used as an effective model for cooperation and participation of the relevant aid organizations. Objective: This study aimed to identify the type and method of
humanitarian aid to support people affected by the Kermanshah earthquake and discuss the importance of the cluster approach in humanitarian response. Methods: In this descriptive cross-sectional study, the data were collected in two steps. First, NEWS and national reports were reviewed and then scientific articles were reviewed for the use of cluster approach for humanitarian aids in disaster. Finally, the findings were compared with the cluster approach of
humanitarian aid and analyzed gap and duplication issues in the
humanitarian aid related to the Kermanshah earthquake. Results: Findings showed ۳۰۸ pieces of NEWS and reports on
humanitarian aid transmission were found, ۳۸ % (۳۳) of which were from government agencies and ۶۲% from non-governmental institutes. A review of the NEWS agencies revealed that ۱۵۰ non-governmental organizations (NGOs) and ۳۳ government agencies had helped Kermanshah by sending financial and non-financial aids. Therefore, the cluster approach is necessary for improving humanitarian responses in developing countries, especially countries located in disaster-prone zones. Therefore, the cluster model can be used in the social donation and can be managed by volunteer organizations during disasters for collecting and transferring the donations. Conclusion: The Cluster model is designed as a solution to promote humanitarian response management. This approach is used as an effective model for cooperation and participation of the relevant aid organizations. There are currently ۱۱ clusters including agriculture, camp management, rapid recovery, education, shelter, telecommunications, health, support, water and sanitation, nutrition, protection and health.
