All over the world water is very scarce and
polluted

• This project was taken by our students along
  with students of Sadiki SchoolTunis, Tunisia and
  State Secondary School Braka Miladinovci
  SkopjeRepublic of Macedonia.
• The topic was and is a tough one and our
  students with my guidance worked very hard to
  compile the data and pictures .
• It was a very interesting to work in the learning
  circle. And this is the first time I participated
  in an iearn learning circle. Though not easy it
  was fun and created lot of interest
• We conducted video conferences with Passaic
  Valley High School USA and Jody Kennedy /
  Eastview Middle School/White Plains New York last
  year. But this was really very creative and
  required a lot of spade work.
• My heartful thanks to Salima of Tunisia and Radha
  of Macedonia
• And special thanks to Barry and Minoo, iEARN
  coordinators for their guidance and very fast
  reply to our doubts. Hats off to them

Realising the gravity of drinking water scarcity
and pollution

• Availability of drinking water
• Some countries in Asia, Europe and North America
  provide Tap water especially in the cities
  .however in many countries like INDIA pakistan
  and other third world countries where there is no
  installations people go for long walks and
  distances to get drinkable water

Man-made drought and the looming water crisis
5
Distress signals of scarcity

• A new field of activity of tappinggroundwater by
  means of borewells hasbeen allowed to grow
  unchecked. Highlyfractured rocks at depth do
  hold considerablequantity of water under
  pressure.Powerful pumps are able to suck
  thiswater .

6
separate water for drinking and washing

• The same water is used for both washing and
  drinking.People should be made aware of the
  importance of this valuable resource.

7
In India water is more valuable than gold

water is not a major problem for some countries
of the world .People pay for clean non polluted
water
8
Ground Water table in India and other Countries

• In India and particularly in Chennai the lowest
  depth for water is 175 feet and highest is 750
  feet .
• In tunisia water available within 10 feet
• Other countries too have water in low depth

Dry water tanks

• Tanks are an essential part of our village
• life and have a major role to play in
• conserving water resources. They have,
• however, been sadly neglected and their
• utility has been completely lost.
• India had a good water-management system,
• with authority vested in the local
• community. Traditional methods were
• unfortunately scrapped by vested interests

Pollution and Global warming

• Unknown to most people, the world is facing the
  gravest danger
• Global warming caused by air and water pollution

The Guarani is the largest aquifer in
South America. It extends more than 1.2 million
square kilometers in Brazil aloneequal to the
areas of England, France, and Spain combined.
The system is shared by Argentina, Brazil,
Paraguay, and Uruguay, and it already supplies
some 15 million people in the region. Best
estimates show that the Guarani contains enough
water to supply 360 million people if this unique
resource is protected and managed sustainably.

Steps to prevent Water Scarcity
Rain Water Harvesting

• Save the rain water.
• Dont waste in the drain.
• Build rainwater harvesting in every house

Water harvesting a time-tested technique Our
forefathers had a clear conception of the above
characteristics of the Indian monsoon rainfall
and in their wisdom constructed numerous
water-harvesting structures in different states
of India.

Steps to prevent Water Scarcity
Rain Water Harvesting
There should be a shift in emphasis to storing
water in large underground reservoirs and
effecting supplies of measured quantities through
pipes. Adoption of drip and sprinkler
irrigation should become common practice and
farmers should be educated in simple
techniques of measurement of soil moisture and
the application of only the right quantity of
water at the right time. Flooding fields with
water and using groundwater for growing crops
like sugarcane and paddy should be strictly
prohibited.

SOLUTIONS
Use other natural resources instead of petrol to
create a less polluted environment. Solar energy
should be encouraged. Use the sea water to
irrigate agricultural lands, after taking out the
salt
