Q. 20. Answer the following : 18
1. Taking into consideration the nature and scope of disaster, which aspects of disaster are important for common citizens ?
Ans Phase of emergency: Important character of this phase is that maximum lives can be saved by quick actions during this phase only. Various actions like search and rescue operations, medical assistance, first aid, restoring communication services, removing the people from affected area are expected in this phase. Gravity of disaster can be estimated in this phase only.
Transitional Phase: Rehabilitation work is started in this phase, after the subsidence of any type of disaster. It includes clearing of debris, restoring water supply, repairing roads, etc. so that it will help to bring normalcy in public life. Rehabilitation of the victims is important aspect of this phase. Generally, different institutes offer the monetary and other type of help to such people. It helps to soothe the mental stress at the earliest if these victims are offered with the permanent mean of earning livelihood and this is true rehabilitation.
Reconstruction Phase: People reconstruct their buildings and facilities like roads and water supply are restored. Farming practices are restarted. However, it takes long time for reconstruction.

Q. 21. Answer the following in detail 55
1. Which are the destructive effects of floods ?
Ans:
2. Effects of disaster:
We have understood the serious effects of a disaster. Collapsing of bridges, flooding of coastal villages, and shortage of food are some of the problems of floods. Collapsing of houses, and developing cracks in the land are some of the effects of earthquakes. Disasters like forest fires and droughts also adversely affect the environment. However, what is the exact nature of these disasters? Whether there are any changes in nature before the occurrence of disasters? For how long did the effects occur after the occurrence of the disaster? How? It needs to be thought over all these aspects. This helps us to understand the nature and gravity of the disaster. Disasters definitely affect the economy of the nation. That effect is always relative to disaster and the economy i.e. if any port is destroyed, there are long-lasting effects on the economy due to huge expenses on its reconstruction. An effect of the disaster on social leadership is that if local leadership is not strong enough, citizens become confused. It affects their participation in rescue and rehabilitation activities. Administrative problems arise during the disaster. If local governing bodies are affected by disasters, related departments cannot answer the problems of disaster efficiently. All the concerned departments are affected by the disaster and thereby entire system collapses.

Social:
with rehabilitation. People have some psychological impact also. They don’t have time and interest in social life.
Medical: Injuries, emotional/mental stress, increase in epidemics, death of victims.
Administrative problems arise during disasters. If the local leadership is not
Political:
strong enough, there is lot of chaos and confusion thereby entire system collapses.
Economic: Sudden increase in fund expenditure, shortage of funds for development of other sectors, decrease in productivity.
4. How can disasters be classified depending upon various criteria ?
Ans
5. i. Lack of management of which factor is shown in the picture?
ii. How can that factor be managed with the help of microbes? iii.How the oil spills in oceans are cleared?
Ans i. The picture shows the lack of management of waste water / sewage.
- Microbes which can decompose any compound as well as destroy the pathogens of cholera, typhoid, etc. are mixed with sewage. They release methane and CO2 by decomposition of the carbon compounds present in sewage. Phenol oxidizing bacteria decompose the xenobiotic chemicals present in sewage.
- Hydrocarbonoclastic bacteria like Alcanivorax borkumensis & Pseudomonas are used to clear the oil spillage from ocean water. These bacteria decompose the hydrocarbons and the bring about the reaction of released carbon with oxygen to produce CO2 & water.

accident scene, this scenario leaves about 12 minutes to extricate the wounded and take them to the hospital.
iii. Secure the accident scene, with the help of pre-warning vehicle, staff, red flags and sign trailers should be erected at the appropriate distance so that the motorist can reduce their
speeds.
iv. Follow the traffic rules. Look at left and right sides while crossing the road and ensure that any vehicle in not passing by.
v. Do not make chaos at the crowded places.
At the site of accidents there is the potential for unstable energy sources like puddles of
Effect of accident –
leaking corrosives, flames, or exposed electrical wires, or they may be more covert, such as an unstable wall, an undeployed vehicle air bag, or a high tension cable that can be re‐ energized without warning. One must have knowledge to look out for them.
Remedies – i. Learning from past accidents can prevent accidents from happening again.
ii. Sign boards and marking on roads can be done at the areas with blind turns or accident prone zones.
- Traffic lights at signals should be working( people should follow them).
Land Slides: Safety protocols –
i.Keep yourself alert and awake.
ii. Listen to a local news station for updates. Using a battery-powered radio or television, iii. Iii. Evacuate if it is safe to do so.
