There are more displaced people worldwide than ever before, and humanitarian crises often occur in unstable and inaccessible places. One group whose efforts are receiving recognition is diasporas. Diasporas are made up of former migrants and refugees who can play a role in supporting their country of origin through fundraising, development work, and in some cases political activity. Recognizing the skills and knowledge of diasporas, agencies such as the International Organization for Migration and the United Nations Development Programme offer practical programs for skilled diaspora members to help them return temporarily to their country of origin to provide training in their area of expertise. Host countries can recognize the considerable diasporas that reside within their own communities. This includes recognizing the political importance of diasporas, which could also serve as an early warning system for changing developments in their countries of origin.
