Disaster management is multi-disciplinary so ASEAN needs many areas of expertise which are best practiced by different types of agencies. AADMER Partnership Group (APG) is a consortium of international non-governmental organizations. It consists of seven organizations, including Child Fund International, Help Age International, Mercy Malaysia, Oxfam, Plan Organization, Save the Children and World Vision International. “The APG aims to strengthen ASEAN’s humanitarian response and disaster risk reduction strategies through enhancing the collaboration between civil society organizations (CSO) and ASEAN governments on the activities under the AADMER Work Program” (Carreon 2011). The APG looks for and facilitates further resource mobilization to ensure the continued support for the AADMER Work Program. It fulfills the principle of involving all stakeholders in regional disaster management and also directly participates in ASEAN’s disaster-related programs, including all meetings of the ACDM. This initiative is very important for two reasons. First, APG has expertise and manpower trained in specific skills dealing with specific issues. Second, the CSO is believed to be both a primary source of assistance on special issues that emerge during a disaster, and a secondary support partner when needed. Thus, the provision of an organized and systematic arrangement for the APG will help improve ASEAN operation effectiveness.
