Disasters caused by natural and human-made hazards often result in mass-movement of populations. Within these movements, companion and production animals can have significant impacts on the internally displaced persons, refugees, and disaster managers. The humanitarian agency Sphere recently identified and highlighted the fact that animal welfare and protecting the livestock of rural communities (before and after disasters) is crucial to the survival of those disaster-impacted communities. Those who are faced with the decision to move will consider the impact and risk/benefit evaluation of housing, losing companion animals, or the loss of production animals necessary for food security and economic survival. Animal impacts also include the potential to spread zoonotic or animal transboundary diseases, raise security concerns within camps, loss of future breeding stock, feeding, housing, and maintaining accountability. Issues involved with animals and refugees in the evacuation decision process, during movement, and in ad hoc, developing, and mature refugee camps will be discussed.
