Disaster Managment

2. Disaster Management
• A natural disaster is a major adverse event resulting
from natural processes of the Earth
• Examples include floods, volcanic eruptions,
earthquakes, tsunamis, and other geologic processes.
A natural disaster can cause loss of life or property
damage, and typically leaves some economic damage
in its wake, the severity of which depends on the
affected population's resilience, or ability to recover.

3. Floods
• A flood is an overflow of water that submerges land
which is usually dry. The European Union Floods
Directive defines a flood as a covering by water of
land not normally covered by water.In the sense of
"flowing water", the word may also be applied to the
inflow of the tide. Flooding may occur as an
overflow of water from water bodies, such as a river
or lake, in which the water overtops or breaks levees,
resulting in some of that water escaping its usual
boundaries,

4. Effects of Floods
• The primary effects of flooding include loss of life,
damage to buildings and other structures, including
bridges, sewerage systems, roadways and canals.
• Economic hardship due to a temporary decline in
tourism, rebuilding costs, or food shortages leading to
price increases is a common after-effect of severe
flooding. The impact on those affected may cause
psychological damage to those affected, in particular
where deaths, serious injuries and loss of property

5. Precautions taken while flood
• Do not walk through moving water. As little as 6
inches of moving water can make you fall.
• If you have to walk in water, wherever possible,
walk where the water is not moving. Use a stick
to check the firmness of the ground in front of you.
• Do not drive into flooded areas. If floodwaters
rise around your car, abandon the car and move to
higher ground if you can do so safely.
• Do not touch electrical equipment if you are wet
or standing in water.

6. Causes of Floods
Rivers can overflow their banks to cause flooding.
Each time there are more rains than the drainage system can
take, there can be floods.
Sea water can be carried by massive winds and hurricanes
onto dry coastal lands and cause flooding.
Dams are man-made blocks mounted to hold water flowing
down from a highland.
In many cold regions, heavy snow over the winter usually
stays un-melted for sometime. There are also mountains that
have ice on top of them.

11. Drought
• A drought is a period of below-average precipitation
in a given region, resulting in prolonged shortages in
its waters supply, whether atmospheric, surface
or ground water. A drought can last for months or
years, or may be declared after as few as 15 days. It
can have a substantial impact on
the ecosystem and agriculture of the affected region.
Although droughts can persist for several years, even
a short, intense drought can cause significant
damage and harm to the local economy.

12. Effects of drought
• Drought can have many devastating effects on communities and
the surrounding environment. The amount of devastation
depends on the strength of the drought and the length of time
an area is considered to be in drought conditions. Drought has
greater impacts on poorer communities than on more prosperous
communities who have better opportunities to bring in resources
from other areas.
• One impact of drought on communities is its effect on water
supply. When drought conditions persist with no relief, or not
enough precipitation to lift the drought conditions, water
restrictions are put into place by local or state governments.
This is important since communities need to ration water
consumption so that the reservoirs and streams do not run too
low on water to meet the needs of utility companies and others
who use water as well as the local ecosystems.

13. Precautions to be taken while drought
Determine the optimum stocking rate.
Develop a marketing plan that will make money when
reducing stocking rate.
Develop a hay storage plan.
Develop a relocation plan for the base herd to an area not
affected by drought.
Before a drought to reduce risk exposure to droughts.
 During a drought to minimize the damage caused be the
drought.
