Disasters

            1
Natural Disasters
A natural disaster is the effect of a
natural hazard (e.g., flood, tornado,
hurricane, volcanic erruption,
earthquake, heatwave, or landslide). It
leads to financial, environmental and
human losses.

                                          2
Floods
A flood is an overflow of an expanse of water that
  submerges land. A flood is a temporary covering of
  land by water not normally covered by water. Flooding
  may result from the volume of water within a body of
  water, such as a river or lake, which overflows or breaks
  levees, with the result that some of the water escapes its
  usual boundaries. While the size of a lake or other body
  of water will vary with seasonal changes in precipitation
  and snow melt, it is not a significant flood unless such
  escapes of water endanger land areas used by man like a
  village, city or other inhabited area.
                                                           3
2011 Floods in Sindh
   The 2011 Sindh floods began during the Pakistani
    monsoon season in mid-August 2011, resulting from
    heavy monsoon rains in Sindh, eastern Balochistan, and
    southern Punjab.

    The floods have caused considerable damage; an
    estimated 434 civilians have been killed, with more than
    5.3 million people and 1.5 million homes affected.



                                                           4
Continue…
 The flooding follows the previous year's
 historic 2010 Pakistan floods, which
 devastated the entire country.
 Unprecedented torrential monsoon rains
 caused severe flooding in 16 districts of
 Sindh province.



                                             5
Continue…..

 Sindh  is a fertile region and often called the
  "breadbasket" of the country; the damage
  and toll of the floods on the local agrarian
  economy is said to be extensive.
 At least 1.7 million acres of arable land
  have been inundated as a result of the
  flooding.

                                               6
How to Prevent from the Floods
 By making more Dams.
 By planting trees along the rivers and canals.

 By proper maintenance of rivers and canals.

 By strengthening the banks of the rivers.

 By maintaining drainage systems.




                                                   7
How to Prevent from the Diseases
 By shifting affected people to safer places.
 By Vaccination of common diseases.

 By providing immediate medical care.

 By draining out of the stagnant waters.




                                                 8
How to save the country from flood
       damages and losses.
 To establish disaster relief organizations.
 To train the disaster relief workers.

 By creating awareness in the people for the
  rescue.
 By strong communication.




                                                9
Economic Affects
   The crops and cattles got expensive and in lack amount.
   Industries based on agriculture and cattle ranching got
    in loss.
   A number of houses and industries got damaged.
   It will lead to the damages of roads, collapse of bridges
    or traffic congestion.
   Inflation.
   Resources used in reconstruction.


                                                           10
Social Affects
 A large part of population displaced from their
  homes.
 Increase in unemployment.

 A huge destruction of educational institutions

  long time to recover.


                                                    11
