The document discusses the global and Indian water crisis. It notes that over 1 billion people lack access to safe water and 2 out of 3 people will face water shortages by 2025. In India, groundwater is being depleted, surface water is polluted, and rainfall is being wasted. This puts pressure on India's population and economic growth. Some solutions proposed include investing in desalination plants, implementing water footprinting to improve conservation, harvesting rainwater, and increasing awareness through social media. However, addressing the water crisis requires consideration of cultural, educational, technological and scientific factors.

WATER

3. Is There Really A Water Crisis?
Over 1 billion people lack access to safe water
2 out of 3 people will be living with water shortages by 2025
Half of the world's wetlands have been lost since 1900.
The basis for most projections for future conflicts is that with the
growth of demand, the decline in freshwater availability , and the
adverse health effects from poor water quality, scarcity will result
in violence and water wars.
YES

4. ? Why…
[Situation]

5. The global situation

6. The global situation
• Less than 3% of the world’s water is
fresh – the rest is seawater and
undrinkable.
• Of this 3% over 2.5% is frozen, locked
up in Antarctica, the Arctic and glaciers,
and not available to man.
• Thus humanity must rely on this 0.5%
for all of man’s and ecosystem’s fresh
water needs.

7. TheIndian situation
PM's Independence Day Speech, 2009
Dr Manmohan Singh, said:
“Climate change is threatening our ecosystems; water scarcity
is becoming a way of life and pollution is a growing threat to
our health and habitat.”

8. TheIndian situation
India has 16 % of the world’s population and 4% of its fresh water
resources.

fresh water supply:
• Brazil
• Russia
• China
• Canada,
• Indonesia
• U.S
• India

• Democratic Republic
of Congo.

14. The Indian situation
India receives abundant rains compared to other water scared
countries but…
This map shows how
much water the Indian
infrastructure fails to
store!

15. The Indian situation
The Indian Government
• Indian government is too focused on economic growth, instead of
facilitating in basic human needs.
• Poor water Management system.
• Biofuel threatens India water supply.
• Package Water Industries are encouraged.

30. Signs of hope…
[Solution]

31. Solution
Progress is Must,
But
Environment is
First.

32. Solution
Solutions to water problems require the consideration of cultural,
educational, communication and scientific aspects.
Plant Trees
Avoid Pollution
Conserve water
Technologies and Innovations
Water Purification Systems
Seawater desalination
Water Footprint

33. Solution
The much-awaited seawater desalination plant, the largest in the country with a
capacity of 100 MLD (million litres per day), coming up near Minjur about 35 km
north of Chennai .
Under the technology, developed by the National Institute of Ocean Technology
(NIOT), warm water is pumped into a vacuum flash chamber and the resultant
vapour is condensed using cold water to get crystal clear potable water.
Desalinated water is of a better quality and the cost is only 6 paise per litre.

34. Solution
Water Footprint
To manage the water consumption better.
A water footprint measures the total amount of water
it takes for a company to manufacture and transport a
product, or for a city, country, or business to operate.
Calculating water footprints can help businesses and
communities better understand and prepare for the
impacts of global water scarcity, according to experts.
Such data allows companies to identify potential
water savings and plan for future shortages

35. Solution
• Rain Water Harvesting
• Irrigation Water Management
• Hydrological projects - Construction of Dams
• Artificial Recharge to Ground Water through Dug well

36. Solution
National River Linking Project

37. Solution
Try to do one thing each day that will result in saving water. Don't worry if the savings
are minimal every drop counts! You can make a difference.
Remember to use only the amount you actually need.
Form a group of water-conscious people and encourage your friends and neighbors
to be part of this group. Promote water conservation in community newsletters and
on bulletin boards.
Encourage your friends, neighbors and co-workers to also contribute.
Encourage your family to keep looking for new ways to conserve water in and
around your home.
Make sure that your home is leak-free. Many homes have leaking pipes that go
unnoticed.
Do not leave the tap running while you are brushing your teeth or soaping your face.

38. Solution
Avoid flushing the toilet unnecessarily. Put a brick or any other device that occupies
space to cut down on the amount of water needed for each flush.
When washing the car, use water from a bucket and not a hosepipe.
Do not throw away water that has been used for washing vegetables, rice or dals.
Use it to water plants or to clean the floors, etc
You can store water in a variety of ways. A simple method is to place a drum on a
raised platform directly under the rainwater collection source. You can also collect
water in a bucket during the rainy season.
Donate fund for ongoing projects.

39. Solution
Water awareness groups among social media networking sites like Twitter,
Facebook are creating new trend among the social awareness groups.
Web 2.0 concept helps to bridge gap between the people – more interactive
By doing this water project, I have learned more about saving a drop of water rather
using wordpress 
Its not a solution to be found, it should be a RESOLUTION everyone should take.
