Summary And Conclusion

Drought is an insidious natural hazard that is a normal part of the climate of virtually all regions. It should not be viewed as merely a physical phenomenon. Rather, drought is the result of the interplay between a natural event and the

demand placed on a water supply by human-use systems. It becomes a disaster if it has a serious negative impact on people in the absence of adequate mitigating measures.

Many definitions of drought exist; it is unrealistic to expect a universal definition to be derived. Drought can be grouped by type of disciplinary perspective as follows: mete-

orological, agricultural, hydrological, and socioeconomic. Each discipline incorporates different physical and biological factors in its definition. But above all, we are concerned with the impact of drought on people. Thus, definitions should be impact oriented, combining both physical and socioeconomic aspects, in order to be used operationally by decision makers. Definitions should also reflect the unique regional climatic characteristics.

The three characteristics that differentiate one drought from another are intensity, duration, and spatial extent. Intensity refers to the degree of precipitation shortfall and/or the severity of impacts associated with the departure. Intensity is closely linked to the duration of the event. Droughts normally take 2 to 3 months to become established but may then persist for months or years, although the intensity and spatial character of the event will change from month to month or season to season.

The impacts of drought are diverse and depend on the underlying vulnerability of the population. Vulnerability, in turn, is determined by a combination of social, economic, cultural, and political factors, at both micro and macro levels. In many parts of the world, it appears that societal vulnerability to drought is escalating, and at a significant rate. Understanding vulnerability is a critical first step in drought management, for risk reduction and disaster preparedness. A good vulnerability analysis can play a key role in underpinning a DEWS, designed to predict the occurrence and impact of drought. But the purpose of an early warning system is also to elicit a timely response, which in turn depends on adequate resources and political will.

It is imperative that increased emphasis be placed on mitigation, preparedness, and prediction and early warning if society is to reduce the economic and environmental damages associated with drought and its personal hardships. This will require interdisciplinary cooperation and a collaborative effort with policy makers at all levels.

How To Survive The End Of The World

Preparing for Armageddon, Natural Disasters, Nuclear Strikes, the Zombie Apocalypse, and Every Other Threat to Human Life on Earth. Most of us have thought about how we would handle various types of scenarios that could signal the end of the world. There are plenty of movies on the subject, psychological papers, and even survivalists that are part of reality TV shows. Perhaps you have had dreams about being one of the few left and what you would do in order to survive.
