Natural disasters - wildfires, floods, droughts, earthquakes, and hurricanes - cause enormous livestock welfare harm through direct injury, displacement, starvation, dehydration, and disease. Australian wildfires of 2019-2020 killed an estimated 1 billion animals including large numbers of livestock. California wildfires regularly displace thousands of cattle, horses, and other livestock. Welfare implications include burn injuries, smoke inhalation, separation from food and water, and the psychological stress of displacement and unfamiliar environments. Emergency preparedness planning for livestock requires: evacuation plans with transport capacity, identified reception facilities, feed stockpiles, and trained personnel. Flood welfare challenges include injury from fast-moving water, prolonged immersion causing hypothermia, and disease outbreaks in survivors. Drought welfare management involves feed supplementation, earlier weaning, and destocking decisions. International veterinary emergency response organisations including WVS (World Veterinary Service) and FAO provide emergency livestock welfare support in disaster zones.
