This Field Operations Guide (FOG) for Disaster Assessment and Response has been developed by the U. S. Agency for International Development/Bureau for Democracy, Conflict, and Humanitarian Assistance/Office of U. S. Foreign Disaster Assistance (OFDA) as a reference tool for individuals sent to disaster sites to undertake initial assessments or to participate as members of an OFDA Disaster Assistance Response Team (DART). The FOG contains information on general responsibilities for disaster responders, formats and reference material for assessing and reporting on populations at risk, DART position descriptions and duty checklists, descriptions of OFDA stockpile commodities, general information related to disaster activities, information on working with the military in the field, and a glossary of acronyms and terms used by OFDA and other organizations with which OFDA works.
