PRESENT DAY ISSUE OF WATER
SCARCITY
in
the
world
AND
METHODS OF CONSERVATION

3. WATER SCARCITY

Water scarcity is the lack of sufficient available
water resources to meet the demands of water usage
within a region.

It currently affects around 2.8 billion people around
the world, on all continents, at least one month out of
every year and more than 1.2 billion people lack the
access to clean drinking water.

4. Water scarcity can be a result of two
mechanisms:
◦ Physical water scarcity
&
◦ Economic water scarcity
where physical water scarcity is a result of
inadequate natural water resources to
supply a region's demand, and economic
water scarcity is a result of poor
management of the sufficient available
water resources

5. ISSUE OF WATER SCARCITY in
India
As a country that receives copious rain, water scarcity in India is
mainly attributed to human factors such as:



India's population have steadily risen since independence. Absence
of comprehensive family planning, and lack of education, spurred
this. This in turn has increased the demand for water. But, no
government has so far been able to equate the difference of water
distribution - more than 50% of the country's population lack access
to safe drinking water.
Corruption and lack of planning and coordination are also blamed
as factors of water scarcity in India. Many projects to supply safe
drinking water are often stuck in red tape.
More than 80% of water needs of the country is met by exploiting
the ground water resources of India. This has aggravated the
depletion of water table, and led to an unprecedented water
shortage.

6. Per Capita Water
Availability in INDIA

The per capita availability of water in the country is
1545 cubic meters as per the 2011 CENSUS. The
average annual per capita availability of water in the
country, taking into consideration the population of the
country as per the 2001 census, was 1816 cubic meters
which reduced to 1545 cubic meters as per the 2011
census, denoting that the per capita water availability in
the country is reducing progressively due to increase in
population.

7. 
Also there are reports that demand for
water in India would rise dramatically to
about 833 cubic kilometers in 2025 and
899 cubic kilometers in 2050 due to
increase in population, rapid urbanization
and a growing GDP with significant
lifestyle changes.

SCARCITY

12. ISN’T THERE ANY WAY TO SOLVE THIS PROBLEM
??????

13. 
Well, there is a solution always to resolve
these problems
◦ to save our future from getting destroyed and
give to our children………
We can act upon it smartly and quickly for the
future.
Government and NGO’s are already in action
and have taken steps to prevent this situation.

14. COUNTER MEASURES FOR
THIS WASTAGE OF WATER
 Community
led initiatives
 Government
led initiatives
◦ National Water Mission
◦ Exploitation of Ground water
 Rainwater harvesting
 Farm ponds

15. Community led initiatives

With support from government and UNICEF,
villagers in Palve Budruk, located in the
drought-prone Parner Block in Ahmednagar
district of Maharashtra, developed a catchment
plan covering 1,400 hectors – that’s over 80% of
the land available. The system has three check
dams, 20 canal bunds, two small percolation
tanks linked to the main tank and 19 village
ponds.

16. Government led initiatives

National Water Mission
The Mission Document for National Water
Mission was drafted by the Ministry of
Water Resources through consultative
process with full involvement of State
Governments, concerned Central
Ministries, Non-Governmental
Organizations, academicians and other
stakeholders.

17. FIVE GOALS IDENTIFIED IN THE
NATIONAL WATER MISSION ARE:
Comprehensive water data base in public domain and
assessment of the impact of climate change on water
resources;

Promotion of citizen and state actions for water conservation,
augmentation and preservation;

Focused attention to vulnerable areas including overexploited areas;

Increasing water use efficiency by 20%;

Promotion of basin level integrated water resources
management.

18. EXPLOITATION OF GROUND
WATER

The Central Ground Water Authority (CGWA) has notified 82
areas (Districts, Blocks, Mandals, Talukas, Municipalities) for
regulation of ground water development. In these areas,
installation of new ground water abstraction structures is not
permitted without prior specific approval of the Authority /
Authorized officer. Moreover, proposals for setting up/expansion
of ground water based industries including bottled water
manufacturing units are forwarded by State Pollution Control
Boards and Bureau of Indian Standards to CGWA for seeking
No Objection Certificate (NOC) for ground water withdrawal.

19. TWO STEPS TAKES FOR
EXPLOITATION OF GROUND
WATER

Rainwater harvesting - Rain water is accumulated
and used for ground water recharge. This
increases the ground water availability.

Farm pond - Farm ponds are constructed near the
farming field. The rain water which runs off the
ground are collected by these ponds. These ponds
helps agriculture in dry lands.
