Disaster is a very common phenomenon to the human society. It has been experienced by them since time immemorial. Though its form may be varied, it has been a challenge for society across castes, creeds, communities and countries. The latest development which has been discovered in the World Disaster Reports recently is that the disasters have increased in frequency and intensity.
People are becoming more and more vulnerable to disasters of all types, including earthquake, flood, cyclones, landslides, droughts, accidents, plane crash, forests fire, etc. With the technological advancements and progress, the force of disasters is also changing. When they occur they surpass all preparedness and eagerness of society and pose bigger challenge to them. This is quite true in case of both developed and developing countries. The floods in UK, France, and heat wave in Europe, particularly in France in 2003, claimed more than 35000 lives. In the year 2006, America had to face bigger disaster in the form of tornadoes and other cyclones. They caused great loss of lives and property. All these are sufficient to prove that technological mechanisms are inadequate.
There is a direct correlation between higher human development and higher preparedness. The countries which have lesser human development are more vulnerable to risks of disasters and damage. Of all the disasters, floods are the most common followed by wind storms, droughts and earthquakes. But the drought is the deadliest disaster which accounts for 48 per cent of all deaths from natural disasters. The highest numbers of people die from disasters in Asia. India, China and Bangladesh are the worst affected countries by flood. Besides the natural disasters, transport accidents and technological disasters are also faced by the developing countries.
