Disaster can take many forms, from famine and earthquakes to industrial accidents and war. While many disasters are natural in origin, the world is increasingly experiencing disasters caused by climate change, deforestation and other human activity.
Disasters can bring tragedy and misery wherever they strike. Wealthy countries are generally well placed to respond, although they can still suffer grave consequences; for example, Hurricane Katrina in the United States killed over 1800 people and permanently displaced over a million people. In developing countries the impacts of disasters are often magnified by factors such as poor infrastructure and meagre response resources.
