It is integrated into the Environmental Epidemiology Research Group and the Climate Change Chair of the University of Oviedo and is part of the Emergency Aid Network (ReliefWeb) of the United Nations Department of Humanitarian Affairs and the Global Alliance on War, Conflict and Health (GAWCH). The UIED manages the Disaster Database and Multiple Casualties Incidents databases of Spain.
