Natural disasters such as earthquakes, floods, typhoons, and hurricanes
inflict serious damage and so seem to be bad for the economy. For firms,
natural disasters destroy tangible assets such as buildings and equipment as
well as human capital and thereby deteriorate their production capacity. These
adverse impacts may sometimes be fatal to the firms and result in them being
forced to close down.
But the academic evidence on the economic impact of natural disasters is
More than 9,000 people have lost their lives and more than 23,000
are injured till date. After shocks from these earthquakes have continued till date.
OF SERVICES RELATED TO WASH
Thousands of people
indisplacement sites / temporary tents were without basic water supply and sanitation
services immediately after the earthquake.Destruction of water system sacross 14
districts left around 1.1 million people without access to protected water sources
1,570 water supply systems sustained major
damage while 3,663 were partially damaged and 220,000 toilets were rendered unusable
in the14 most affected districts.It could cost US$100 million to restore the WASH
sector toits pre-earthquake status (UNICEF).
1.2 DAMAGES TO HYDROPOWER
The earthquake is reported to have damaged 14 hydropower projects
resulting in 115MW Hydropower generation facilities being severely damages and 60MW
partially damaged (NPC).Other under construction hydropower projects of 1000MW capacity
were also affected.The overall energy sector sustained losses worth Rs18.75billion.
1.3 CONTAMINATION OF WATER BODIES
Decaying bodies of the deceased humans and animals, their mass
cremation, ,septic failure, and cross-contamination of the sewer lines with the
drinking water distribution systems could impact surface and groundwater quality,
thus increasing the risk of water-borne illnesses post-earthquake.Toxic chemicals
released from households and industries will be soaked into the soil and will eventually
end up in ground water or rivers, contaminating drinking water sources of millions
1.4 EFFECTS ON SURFACE WATER
Springs and traditional stone spouts dried up in many places where
as new ones appeared at other places, resulting in severe water shortage and also
instigated conflicts between communities.A large number of landslides triggered
by the earthquake resulted in the generating an estimated 19,118,538m3 of sediment,
drastically increasing sediment loads in downstream water courses. Increased
sand, clay and slit particles may result in rising river beds, sedimentation and
flooding in flatter low-lying areas / Terai and also adversely impact aquatic flora
1.5 IMPACT ON GROUNDWATER RESERVOIRS
Ground water level retreated in many places and the ground
water recharge system was severely impacted.
