Short notes on Disaster Management is provided to ensure the best understanding of the topic for the students who are making projects on the topic or preparing for the exam. A disaster is a destructive event that occurs suddenly and involves loss of life and property. Disasters can be of two types, natural and man-made. They are a result of natural activities and hence known as natural disasters. Some of the man-made disasters are: bomb explosions, terrorism, war or civil war, leakage of poisonous chemicals, breach in dams, air or water pollution, industrial accidents and epidemics.
FLOODS A flood is an overflow of a large amount of water beyond its normal limits, especially over what is normally dry land. Any flood is preceded by a threat period known as the Probability Period. This allows the authorities to issue warnings and plan evacuation. Artificial reservoirs should be built with sluice gates and sand bags should be used to block the flow of water. Low grounds or viaducts can be created to carry water in a certain direction or underground.
Trees should be planted in the catchment areas to stop soil erosion. DROUGHTS A drought is a period of below-average precipitation in a given region, resulting in prolonged shortages in its water supply, whether atmospheric, surface water or ground water. It can have a substantial impact on the ecosystem and agriculture of the affected region and harm to the local economy. These surface waters may dry out if the flow from their sources upstream is affected. Global Warming Even though some people do not accept that the average temperature of the earth has risen, it is on record that human actions have contributed to more greenhouse gasses in the atmosphere.
As a result, there are warmer temperatures, often resulting in more dryness and bush fires often causing drought conditions. EFFECTS OF DROUGHTS Diminished crop growth or yield productions and carrying capacity for livestock Dust bowls, themselves a sign of erosion, which further erode the landscape Dust storms, when drought hits an area suffering from desertification and erosion Famine due to lack of water for irrigation Habitat damage, affecting both terrestrial and aquatic wildlife Hunger, drought provides too little water to support food crops.
Desalination — of sea water for irrigation or consumption. For instance, analysis of water usage in Yemen has revealed that their water table underground water level is put at grave risk by over-use to fertilize their Khat crop. Land use — Carefully planned crop rotation can help to minimize erosion and allow farmers to plant less water-dependent crops in drier years.
Outdoor water-use restriction — Regulating the use of sprinklers, hoses or buckets on outdoor plants, filling pools, and other water-intensive home maintenance tasks. Rainwater harvesting — Collection and storage of rainwater from roofs or other suitable catchments.
Recycled water — Former wastewater sewage that has been treated and purified for reuse. Such disasters are caused by microorganisms that cause epidemics. These have spread due to man-made conditions.
