Water Dynamics
AVAILIBILITY, NGO ROLE VITAL
By Dhurjati Mukherjee
The recent Supreme
Court verdict granting Karnataka a larger share of the Cauvery water and
reduced allocation for Tamil Nadu was justified. It upheld rest of 2007
recommendations of Cauvery Water Disputes Tribunal that had failed to satisfy
the two riparian States plus Kerala and Puducherry. It was pertinently pointed
that increasing Karnataka’s share, the issue of drinking water had to be placed
on a “higher pedestal”. However, it can’t be denied that TN’s scarcity
conditions are acute and will put additional burden on the State.
Water has become a
bone of contention and most of the States are suffering due to scarcity
conditions prevailing in the country. It is a known fact that India will become
‘water stressed’ within another 3-4 years due to increasing water use compared
to available resources. The recent Cape Town report has come out at such a time
when Indian cities like Bangalore, Hyderabad and States like Gujarat,
Rajasthan, Madhya Pradesh suffer water shortages during summer months.
People fail to
realise that the problem of water in the country is quite serious and a
situation may emerge when scarcity conditions may be quite acute. While the
crisis in western parts of India is quite well known, the eastern States are
relatively better off. But the situation is destined to change with the growing
pressure of population and increased farming activities. Moreover, rainfall has
become erratic due to climate change, causing either drought like conditions or
flooding.
There is a wrong
perception that nature has provided India with abundance of water. This is
based on the fact that the country has 4 per cent of the world’s annual
renewable fresh water whereas it has only 2.5 per cent of the total land area.
Since about 75 per cent of the total water requirement is for agricultural
needs, hydrologists believe that the right parameter to judge the status of
water availability would be the percentage the arable land area and not the
total land area. As India has to manage around 16.5 per cent of the world’s
human population and about 15 per cent of the world’s animal population, it can
be said that the country today is actually water deficient.
Thus one can safely
say that much before 2020, India would become a water stressed country. The
Washington-based Worldwatch Institute predicted that the country would be a
highly water stressed country from 2020 onwards. It may be pointed out that
according to the Falkenmark Water Stress Indicator, a country or region is said
to experience “water stress” when annual water supplies drop below 1,700 cubic
metres per person per year. At levels between 1,700 and 1,000 cubic meters per
person per year, periodic or limited water shortages can be expected. When a
country is below 1,000 cubic meters per person per year, the country then faces
water scarcity.
Meanwhile, there are
reports of fast depleting ground water in nearly 30 per cent of the assessed
blocks in the country. The last assessment of the CGWB shows that 1034 of the
6584 blocks in the country are over-exploited – usually referred as ‘dark
zones’. It means annual ground water consumption in those blocks is more than
the annual ground water recharge. Besides, 934 blocks fall in different stages
of criticality due to depletion without recharge.
The over exploited
zones are mostly concentrated in western India in States of Punjab, Haryana,
Delhi U.P., Rajasthan, Gujarat and also in southern States of Karnataka, Tamil
Nadu and Andhra Pradesh. Out of these, the most affected are Punjab, Haryana
and Rajasthan.
The recent Union
Budget has come out with Rs 6000 crores plan aimed at efficient management of
available water resource and strengthening mechanism through community participation.
Half of the total cost of this Central scheme, named Atal Bhujal Yojana will be supported by the World Bank as loan
while the remaining half will be funded by the government through budgetary
support to deal with the alarming water crisis.
The other aspect of
the problem is the issue of contamination, specially of arsenic and fluoride in
different parts of the country. An alarming 75 per cent or more of India’s
surface water is polluted, an assessment by Water Aid, an international organisation
working for water sanitation and hygiene, pointed out.
The report, based on
latest data from the Ministry of Urban Development (2013), census 2011 and
Central Pollution Control Board, estimated that 75-80 per cent of water
pollution by volume is from domestic sewerage, while untreated sewerage flowing
into water bodies including rivers have almost doubled in recent years. While
availability has become a problem, if this water becomes contaminated, it will
have grave consequences on human health, specially for the poorer sections of
the population.
Around 239 million
people spread across 152 districts in 21 States drink water that contains
unacceptable high levels of arsenic, in effect they are being slowly poisoned.
The Water Resource Ministry’s reply to a question in Lok Sabha, revealed that
65 per cent of Assam’s population or about 21 million people have been drinking
arsenic contaminated water while in Bihar it is 60 per cent and in Bengal 44
per cent of the total population that is dependent on this poisonous cocktail
to quench their thirst. In terms of absolute numbers, UP has the largest number
of people exposed to the risk with over 70 million people consuming the
polluted water.
The WHO has warned
that long-term intake of such water leads to arsenic poisoning or arsenicosis
with cancer of bladder, kidney or lung or diseases of skin -- colour changes
and hard patches on palms or soles or blood vessels of legs and feet. Further
evidence indicates possible association between intake of contaminated water
and onset of diabetes, hypertension and reproductive disorders, as per a WHO
document.
Are we to presume
that our leaders are deliberately not acknowledging this threat and advising
their constituents how best to combat the problem and making investments in the
technology necessary for delivering arsenic-free water? What is the problem in
setting up inexpensive community-run arsenic treatment plants that can ensure
the long term environmental health and economic security of a village or a
urban neighbourhood?
The situation is
indeed quite alarming. The plans taken by the Centre have not been quite
successful. At this juncture not just government support and more financial
allocations are very much needed but simultaneously it is also imperative to
spread awareness among the rural population regarding water and sanitation on a
massive scale, the responsibility for which should be entrusted to NGOs with
expertise and skill. They should also be given the task of training panchayat
representatives as also teaching people in simple terms to change their age-old
practices keeping in view the intrinsic relationship between water, sanitation
and human health.
It needs to be
emphasised here that the voluntary organisations are best suited for the job
because of their grass root approach and also because the work can be
accomplished by them at minimum cost and greater efficiency.
At the same time,
there is need for a programme of epidemiological research on environmental
health impacts in the country related to water, air, soil and ecology in order
to create proper understanding of the problems. And the findings of this
research have to be disseminated at the grass root level so that proper measures
may be taken to safeguard human health.---INFA
