GIZ: Enhancing the ASEAN Regional Disaster Emergency Response Simulation Exercise (ARDEX) South East Asia is the most natural disaster prone region in the world. Often, disasters transcend national borders and overwhelm the capacities of individual countries to manage them. There is a strong need for standardization of emergency preparedness and management mechanisms at the regional level. Based on its vision for “one ASEAN, one response”, the Association of Southeast Asian Nations (ASEAN) has since 2005 regularly implemented the ASEAN Regional Disaster Emergency Response Simulation Exercise (ARDEX). This project is a German-Swiss cooperation for enhancing quality and effectiveness of ARDEX through financial and technical support.
