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. They are known as man made disasters because they occur due to human actions and not natural forces.
In monsoon, there is chance of heavy rainfall. The hillsides are prone to landslide in heavy rainfall i. So, it is never advisable to take shelter near hillsides during monsoon as your life will be at risk as well as you may face problems such as heavy traffic etc.
During an earthquake, the power supplies are cut off and you may get stuck in the elevator for long time. So, it is advised not to use lifts at the time of earthquake. Note: The question language is not comprehensible. This layer absorbs the pressure exerted by the earthquake tremors on the side walls of the building. Due to this, the building does not shake with the same intensity as the earth is shaking.
Page No Question 3: If a crowd gathers at the place of earthquake, what would be the difficulties in relief work? Collect more information about their work.
It provides emergency aid to survivors of war and natural disasters, and helps people rebuild their lives. Page No Question 5: Make a survey of your school according to the plan of disaster managment an write the pointwise information.
Answer: This an activity based questions. Kindly do it yourself.
School disaster management committee: Get the information of the members involved in disaster management committee. Detailed information about school building: Note the number of rooms, classroom, age of the building, types of roofs under this point.
Information about school ground: It should include information like distance of ground from the main road, types of play grounds. Daily routine of the school: It should include information like working time of the school, lunch break time for the school. Possible hazards in the school: It should information such as record of past disaster happened in school, current planning for overcoming disasters.
Page No Are there any possible places of landslide in your area?
Collect information from experts. Answer: This is an activity based question. Page No With the help of following pictures, explain your role in the disaster management. Answer: It seems like the person is texting us that he is at risk. Since the type of risk or disaster is not mentioned, we can make possible guesses and give him following support: First of tell him to calm down and ask him what type of risk is he facing and his location.
Give the police his picture, phone number, address and other details so that they can track him down. We should also try to reach the place as soon as possible.
If he has faced some road accident, then call the ambulance and police to reach there as soon as possible. We should be also there as soon as possible to give him support.
In case of fire, call the fire brigade, ambulance and police giving them all the information and urge them to reach there as early as possible. 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. Most of these have been infectious diseases such as malaria, plague, diphtheria, tuberculosis and influenza.
People can control the spread of these diseases by ensuring hygienic conditions and taking preventive measures. The government has taken a number of steps to contain the spread of these diseases such as fumigation to control the spread of the malarial mosquito.
Chemical and radioactive leakages are also the result of human error and result in far reaching damages.
A chemical accident is the unintentional release of one or more hazardous substances which could harm human health or the environment. Chemical hazards are systems where chemical accidents could occur under certain circumstances.
Protective clothing: Clothing reduces the risk of mosquito biting if the cloth is sufficiently thick or loosely fitting. Long sleeves and trousers with stockings may protect the arms and legs, the preferred sites for mosquito bites.
Schoolchildren should adhere to these practices whenever possible. Mats, coils and aerosols: Household insecticidal products, namely mosquito coils, pyrethrum space spray and aerosols have been used extensively for personal protection against mosquitoes. Electric vaporizer mats and liquid vaporizers are more recent additions which are marketed in practically all urban areas.
Repellents: Repellents are a common means of personal protection against mosquitoes and other biting insects.
