Humanitarian disaster

A humanitarian crisis (or "humanitarian disaster") is defined as a singular event or a series of events that are threatening in terms of health, safety or well being of a community or large group of people. It may be an internal or external conflict and usually occurs throughout a large land area. Local, national and international responses are necessary in such events.

Each humanitarian crisis is caused by different factors and as a result, each different humanitarian crisis requires a unique response targeted towards the specific sectors affected. This can result in either short-term or long-term damage. Humanitarian crises can either be natural disasters, man-made disasters or complex emergencies. In such cases, complex emergencies occur as a result of several factors or events that prevent a large group of people from accessing their fundamental needs, such as food, clean water or safe shelter.

Examples of humanitarian crises include armed conflicts, epidemics, famine, natural disasters and other major emergencies. If such a crisis causes large movements of people it could also become a refugee crisis. As such, humanitarian crises are often interconnected and complex and several national and international agencies play roles in the repercussions of the incidences.

There is no simple categorization of humanitarian crises. Different communities and agencies tend to have definitions related to the concrete situations they face. A local fire service will tend to focus on issues such as flooding and weather induced crises. Medical and health related organizations are naturally focused on sudden crises to the health of a community.

An ongoing or lingering pandemic may amount to a humanitarian crisis, especially where there are increasing levels of virulence, or rates of infection as in the case of AIDS, bird flu or Tuberculosis. Major health-related problems such as cancer, global warming typically require an accentuated or punctuated mass-event to justify a label of "crisis" or "disaster".

The International Federation of Red Cross and Red Crescent Societies (IFRC) lists categories which include different types of natural disasters, technological disasters (i.e. hazardous material spills, Chernobyl-type of nuclear accidents, chemical explosions) and long-term man-made disasters related to "civil strife, civil war and international war". Internationally, the humanitarian response sector has tended to distinguish between natural disasters and complex emergencies which are related to armed conflict and wars.
