To explore issues related to the effects of disasters on children and youth and lessons learned from experiences during previous disasters, the virtual workshop From Hurricane Katrina to Paradise Wildfires, Exploring Themes in Disaster Human Services was convened on July 22 and 23, 2020, by the National Academies of Sciences, Engineering, and Medicine. The workshop was designed to focus on families engaged with federal, state or local supportive programs prior to disasters. Additional areas of focus were the coordination of disaster response efforts and the transition to reestablishing routine service delivery programs post-disaster by human services, social services, and public health agencies at the state, local, tribal, and territorial levels. The workshop was also intended to provide a platform for highlighting promising practices, ongoing challenges, and potential opportunities for coordinated delivery and restoration of social and human services programs. This publication summarizes the presentations and discussion of the workshop.
