On May 3rd and 4th 2012, InterAction members and ten NGO coalitionsi met to discuss humanitarian NGO coordination in Washington, DC. InterAction’s Humanitarian Policy & Practice Team organized and facilitated the meeting with generous funding from USAID’s Office of U.S. Foreign Disaster Assistance (OFDA). The dialogue, a follow on to the first humanitarian NGO coordination dialogue held in January 2011, sought to strengthen linkages between country specific NGO coordination bodies, to identify lessons learned and best practices for creating and maintaining coordination bodies, and to hold a constructive dialogue on how to better engage with the larger UN humanitarian coordination mechanisms, global consortia, and non-traditional humanitarian actors. What follows is a short summary of a rich and varied discussion. It is not meant to be a consensus document or a meeting statement.
