WATER CRISIS

IMPORTANCE OF WATER
• There’s nothing more essential to life on Earth than water.
• If there was no water there would be no life on earth.
• Apart from drinking it to survive, people have many other uses
for water.
• cooking
• washing their bodies
• washing clothes
• washing cooking and eating utensils
• keeping houses and communities clean
• keeping plants alive in gardens and parks
• water is also essential for the healthy growth of
farm crops and farm stock and is used in the
manufacture of many products.
GLOBAL WATER CRISIS
• Water covers 70% of our planet, and it is easy to think that it
will always be plentiful. However, freshwater—the stuff we
drink, bathes in, irrigates our farm fields with—is incredibly
rare. Only 3% of the world’s water is fresh water, and two-
thirds of that is tucked away in frozen glaciers or otherwise
unavailable for our use.
• 1.1 billion people worldwide lack access to water.
• 2.7 billion find water scarce for at least one month of the
year.
GLOBAL WATER CRISIS
• Inadequate sanitation is also a problem for 2.4 billion
people—they are exposed to diseases, such as
cholera and typhoid fever, and other water-borne
illnesses.
• 2 million people, mostly children, die each year from
diarrheal diseases alone.
GLOBAL WATER CRISIS
• Women are disproportionately affected by the water crisis,
as they are often responsible for collecting water. This takes
time away from work, school and caring for family. The lack
of water and sanitation locks women in a cycle of poverty.
GLOBAL WATER CRISIS
• Time spent gathering water or seeking safe sanitation
accounts for billions in lost economic opportunities. Access
to safe water and sanitation at home turns time spent into
time saved, giving families more time to pursue education
and work opportunities that will help them break the cycle
of poverty.
WATER SCARCITY IN PAKISTAN
• According to a recent report by the International Monetary
Fund (IMF), Pakistan ranks 3rd in the world among
countries facing acute water shortage.
• UNDP and PCRWR also warn the authorities that the
country will reach absolute water scarcity by 2025.
WATER SCARCITY IN PAKISTAN
• PCRWR reported that Pakistan touched the "water stress
line" in 1990 and crossed the "water scarcity line" in 2005.
• Per capita surface water availability of 5,260 cubic meters
per year in 1951 turned into around 1,000 cubic meters in
2016. This is likely to further drop to about 860 cubic
meters by 2025.
WATER SCARCITY IN PAKISTAN
• More than 35 percent of the population of our country
lacked access to safe drinking water and this figure could
double in the next 5 to 10 years as still there was no
feasible planning for water development projects.
WATER WASTAGE
• The president of the Apex chamber said that Pakistan is
among the country topping list of wasting water.
• Pakistan continues to waste 30 million acre-foot or 10
trillion gallons of water per annum which can be used to
quench the thirst of masses.
WATER WASTAGE
• The NWP acknowledges that irrigated agriculture is the
backbone of the economy and consumes around 90
percent of the water resources.
• Around 1 million tube wells in the country pump about 55
MAF of underground water for irrigation, signaling how
highly water-intensive the agriculture sector is. This is all
UNSUSTAINABLE.
WATER WASTAGE
• More water is utilized in growing these water-intensive
crops – rice and sugarcane, for example.
• To produce a kilo of sugarcane, between 1,500 and 3,000
liters of water are utilized.
• Pakistan’s rice water productivity is 55 percent lower than
the average water productivity of one kg per cubic meter
for rice in Asian countries.
WATER WASTAGE
• The average person wastes up to 30 gallons of water every
day.
WATER WASTAGE
• Leaks may cause a home to waste 10,000 gallons of water
per year.
• One of the most common ways in which people waste
water is by leaving the water running when brushing their
teeth, shaving or doing the dishes.
WATER WASTAGE
• Using a hose to wash the car can use up gallons of water. If
you leave the hose running, you can end up wasting almost
150 gallons of water.
• A bathtub requires 70 gallons of water.
SOLUTION
• Agriculture: many farmers are relying on groundwater
reserves.
• Many countries have employed technologies reducing
water usage for the agricultural purpose from 90% to 99%.
• Drip irrigation systems deliver water directly to a plant’s
roots, reducing the evaporation that happens with spray
watering systems. Properly installed drip irrigation can save
up to 80% more water than conventional irrigation.
• Timers can be used to schedule watering for the cooler
parts of the day, further reducing water loss.
• Effective water tax can discourage the wastage to trigger
conservation.
SOLUTION
SOLUTION
• DAMS: Pakistan have only 2 big reservoirs and we can save
water only for 30 days. India can store water for 190 days,
US can do it for 900 days and Egypt has the capacity to
store water enough for 1000 days.
• Pakistan receives around 145 MAF of water every year but
can only save 13.7 MAF. Pakistan needs 40 MAF of water
but 29 MAF of our floodwater is wasted because we have
few dams.
SOLUTION
SOLUTION
• Recycling: Achieving more sustainable sanitation and
wastewater management will require emphasis on actions
linked to resource management, such as wastewater reuse
that will keep valuable resources available for productive
uses.
Goreangab Water Reclamation Plant, Namibia
SOLUTION
• WASA has made it mandatory for every service station in
Lahore to install a mechanized water recycling plant.
• The water recycling plant was installed at the Khan CNG
service station located in Rawalpindi.
SOLUTION
• Turn the tap off as soon as you start brushing, shaving or
doing the dishes.
• Equipped with motion sensors, automatic faucets only turn
on and release water if a hand is detected.
SOLUTION
• According to the U.S. Environmental Protection Agency
(EPA), a full bathtub requires about 70 gallons of water,
while taking a 10 minute shower uses 20 to 25 gallons.
• Use a low-flow showerhead or a bucket to save even more
water.
SOLUTION
• Using a bucket to save water while washing a car.
• 100 liters wasted washing a car with running tap water.
