PRESENT DAY ISSUE OF
WATER SCARCITY in the world
AND
METHODS OF CONSERVATION
TOPIC OF THE ASSIGNMENT:-
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.
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
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.
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.
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.

MAP SHOWING THE STATES HIT BY WATER SCARCITY
ISN’T THERE ANY WAY TO SOLVE THIS PROBLEM ??????
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.
COUNTER MEASURES FOR THIS WASTAGE OF WATER
Community led initiatives
Government led initiatives
◦National Water Mission
◦Exploitation of Ground water
Rainwater harvesting
Farm ponds
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.
Government led
initiativesNational Water MissionThe 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.
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 over-
exploited areas;
Increasing water use efficiency by 20%;
Promotion of basin level integrated water resources
management.
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.
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.
