As
India Runs out of Water, Its Desertified Land Comes Into View
The
tipping point of a major ecological crisis is no longer in the
future. It's here and now
20
June, 2018
Is
India turning into a desert? Was the week-long stranglehold of dust,
heat and high humidity that north India witnessed last week a
precursor to what is in store for us in the future?
Dust-laden
winds from western India and the Thar desert blew across this region,
making it difficult to breathe. Even the hill stations of Himachal
Pradesh and Uttarakhand were not spared, with a pall of dust hanging
over Shimla and Mussorie.
This
stranglehold saw PM10 levels shoot up to 900 mg per cubic metre, way
beyond emergency levels. The double whammy of heat and dust will also
have precipitated a surge in the incidence of respiratory disorders.
What
has this got to do with desertification? Everything. The Indian
Institute of Meteorology has issued repeated warnings that the
duration of dry spells in the country are set to increase. While the
average annual rainfall will remain the same, it will come in short,
heavy spurts as was witnessed in Uttarakhand in June 2013.
These
drier spells and our inability to harness rainwater has already seen
more than a quarter of the country become a desert. A study by the
Indian Space Research Organisation, backed by satellite images, shows
that over 32% of India’s land is affected by degradation, of which
desertification is the major component.
This is a frightening
prospect because, in essence, fertile land is being converted into
desert.
The
figures speak for themselves. India’s total geographical area
extends to 329 million hectares (Mha), of which 120 Mha is degraded.
Rajasthan accounts for the most desertified land (23 Mha), followed
by Gujarat, Maharashtra and Jammu and Kashmir (13 Mha each) and
Odisha and Andhra Pradesh (5 Mha each).
These
findings have been seconded by Prakash Javadekar, who, when he was
the environment minister, had said, “Land is becoming barren,
degradation is happening. A lot of areas are on the verge of becoming
deserts but it can be stopped.”
C.P.
Rajendran,
a senior scientist at the Jawaharlal Nehru Centre for Advanced
Scientific Research, Bengaluru, warns that “things are looking very
bad for India. The upper soil is being removed for construction and
road building purposes and this is affecting our soil adversely.”
“Earlier,
soil loss was a slow process which took millions of years. Now, we
have managed to change that in just a few decades, but the natural
time for the soil to regain what it loses is still as long. It is
imperative that we need to stop this entire degradation process on a
top priority basis,” he said.
The
principal concern is that river basins, both big or small, contain
little water.
“Take any river basin and you will find water levels
are diminishing rapidly,” Rajendran explained. “The government
has sanctioned the construction of several dams in Uttarakhand and
the Himachal hills, which are destroying our rivers. With ground
water levels falling, we are not going to be able to regain what we
have lost.”
The
NITI Aayog recently released
a report
titled ‘Composite Water Management Index’, and it only serves to
reiterate what activists have been complaining about for years. The
report states, in unequivocal terms, that “India is undergoing the
worst water crisis in its history. Already, more than 600 million
people are facing acute water shortages. Critical groundwater
resources – which account for 40% of our water supply — are being
depleted at unsustainable rates.”
The
report, released by the Minister of Water Resources, Nitin Gadkari,
further warned that the crisis will only get worse because, by 2030,
the country’s demand for water will be twice the available supply,
creating a severe water crisis for millions of people.
If
that is not dire enough, the report cites data by independent
agencies to emphasise that 70% of water being used in India is
contaminated, thus placing us in the 120th slot among 122 countries
in the water quality index.
A
UNESCO report, published ahead of World Water Day on March 22, should
serve as another wake-up call. India is staring at a deepening water
crisis with few steps being taken to ameliorate this bleak situation.
It predicts an intensified water crisis across the nation by 2050,
with many parts of central India battling a 40% withdrawal of
renewable surface water reяources.
The
UNESCO report claims more than half our rivers are heavily polluted.
Even more alarming is that our groundwater resources contain metallic
contamination and also contamination from improper disposal of human
excreta.
Elaborating
on this, the Central Pollution Control Board (CPCB) has in the last
five years doubled the number of ‘polluted’ rivers from 121 to
275.
The
report found that while Maharashtra had 49 polluted river stretches,
including Mithi, Godavari, Bhima, Krishna, Ulhas, Tapi, Kundalika,
Panchganga, Mula-Mutha, Pelhar, Penganga and Vaitarna, Assam ranked
second at 28, Madhya Pradesh third with 21, Gujarat 20 and West
Bengal 17.
The
situation is no better in the south, where the quantum of water in
the main rivers, including the Godavari, the Cauvery and the Krishna,
has fallen drastically.
The situation has now extended to central India, where fresh surface water resources are also being depleted. The Narmada river, considered one of the few rivers whose flows had been unaffected, has also been hit by a spree of dam construction.

Speaking
on ground water depletion, S.K. Sarkar, a scientist at The Energy
Resources Institute, Delhi, points out that the situation in Punjab,
Haryana and Delhi is so severe that it carries the risk of salinity.
This will significantly impact the crops of millions of farmers who
depend for their survival on groundwater.
The CPCB has issued repeated warnings that if the situation is not reversed
immediately, the “demand for freshwater for all uses will
be unmanageable”.
Shimla
reached this tipping point last month, when taps went dry for 12 days
at the height of its tourist season. It was not just the residents
who had to brace themselves for a waterless summer. Many forest fires
around the city could not be put out because the municipal
corporation had no water. Finally, the state government had to put in
a request for Indian Air Force choppers, which lifted water from the
Gobind Sagar dam in Punjab to douse the flames.
Another
factor feeding the spectre of increasing aridity is rapid
deforestation. For example, the forests of the Aravali hills
protected the National Capital Region, including Delhi, against the
dust from Rajasthan.
But
our political class and bureaucrats do not seem to realise the
gravity of the situation. Despite the Aravali having been designated
a Natural Conservation Zone, environmentalists are crying wolf over
the latest attempt to exclude a large swathe of forest land located
east of the Surajkund-Badhkal road. Chetan Agarwal, an environmental
analyst, recently wrote to the National Capital Region Planning Board
about how a vast track of 5,000 ha of Aravali land was not shown to
be forest by the authorities, obviously keeping in mind the surging
demand for real estate development.
“We
are facing an ecological crisis. Unless we come up with strategy to
preserve our ecological resources which help provide water and
livelihood security, we will see a worsening of the situation,”
said Himanshu Thakkar, an environmental activist who heads the South
Asia Network on Dams, Rivers and People.
Manoj
Misra, another noted environmentalist and head of the Yamuna Jiye
Abhiyaan, said, “While this plume of dust that spread over north
India was transnational and a sure sign of changing climate, I would
like to point out that we need to go to the root of the problem. The
tributaries of most of our rivers are dry.
Despite this lack of
water, hydro projects continue to be constructed without
environmental clearances and without addressing issues of ecology,
seismic concerns and their adverse environmental impacts.”
India
does not have a specific legislative or policy framework to combat
desertification. However, the concern for arresting and reversing
land degradation and desertification is reflected in many policies
and soil conservation programs, but few of which are realised.
An
eminent water conservationist and a Ramon Magsaysay Award recipient,
Rajender Singh has also warned against the impending crisis. “We
are facing severe drought conditions across several states that
include Madhya Pradesh, Maharashtra, Karnataka, Telangana, Andhra
Pradesh and Tamil Nadu. Neither the central nor state governments
have come up with any long-term plan to tackle this situation,” he
said.
He
finds it ironic that, over the centuries, India had developed an
expertise to manage drought and floods — both of which are two
sides of the same coin.
“Traditional,
community-driven, time-tested models on how to handle drought as also
our water resources which helped ensure that our rivers, lakes,
wetlands and other water bodies remained intact over the centuries
but these methods are being totally ignored today,” Singh said.
“It
is these areas of expertise that we should have promoted within India
and across the globe. We were gurus in protecting wildlife and
nature. Other countries could have learnt this knowledge from us. But
in all these international meets, the only green technology being
promoted are technology relates to energy efficiency, whereas our
traditional water management systems are not showcased at all. The
only people assisting our official delegations are corporate
consultants. How do they represent the viewpoint of millions of
Indians?”
Scientists
believe the government should have been at the forefront of
mobilising vulnerable communities to help them harvest rainwater and
to regenerate ecosystems, thereby enhancing nature-based livelihoods.
Climate change adaptation and mitigation should lead this effort by
the Ministry of Environment. However, its only focus seems to be to
facilitate the ease of doing business to the detriment of all else.
