Disaster Response in Asia and the Pacific: A Guide to International Tools and Services is designed to help disaster managers in national Governments gain basic knowledge of how to use international tools and services.The guide is not prescriptive. It aims to support the growing disaster response and disaster response preparedness capabilities that exist at national level across Asia and the Pacific. The guide concentrates on key tools and services that can be helpful to disaster managers during the response and response preparedness phases of the disaster programme cycle. It does not include tools and services encompassed by disaster risk reduction (DRR) efforts, nor does it cover longer-term disaster recovery instruments. The guide includes some entries relevant to conflict situations. It does not include tools or services that are being developed. The guide has three main sections: [I] International Humanitarian Architecture; [II] Tools and Services for Disaster Response; and [III] Tools and Services for Disaster Response Preparedness. The reverse chronological order of the guide - response before response preparedness - is intentional. It deliberately profiles tools and services for response before those for response preparedness to offer a better understanding of the utility of certain response preparedness activities and how they support response efforts. It has been produced in response to a call by UN Members States and other humanitarian stakeholders at the 2011 Regional Humanitarian Partnership Workshop for the AsiaPacific Region held in Shanghai, China for a handbook to guide disaster managers in understanding the interaction between national, regional and international humanitarian response mechanisms.
