Disasters are a form of collective stress posing an unavoidable threat to people around the world. Disaster losses result from interactions among the natural, social, and built environments, which are becoming increasingly complex. The risk of disaster and people's susceptibility to damage or harm from disasters is represented with the concept of vulnerability. Data from the Indian Ocean tsunami, Hurricane Katrina, and genocide in Darfur, Sudan, show poor people suffer disproportionately from disasters. Disaster social work intervenes in the social and built environments to reduce vulnerability and prevent or reduce long-term social, health, and mental health problems from disasters.

This entry provides a brief historical overview of international volunteer service, along with changes to traditional forms of international service. It presents a general typology for contemporary international-service programs and reviews how these forms differ in practice. Using the limited data available, it provides a demographic snapshot of the scale and prevalence of international volunteer service from the United States and globally. The entry then reviews critical intersections between international service and social work, and describes debates of particular concern to the social worker profession. Finally, the entry outlines important areas for future social work research and practice.
