New
Irrigation Scheme
PROJECT
EFFICIENCY VITAL
By Dhurjati

The Government’s recently launched
Pradhan Mantri Krishi Sinchayaa Yojana (PMKSY) for providing irrigation
facilities to every village by creating the much-needed infrastructure is
definitely a step in the right direction. However, the project appears too
ambitious. It has been decided that Rs 50,000 crores would be provided by the
Centre in the next five years to expand irrigation and also to set up a
first-of-its-kind online agricultural market to help farmers get better prices.
At present, around 50 per cent of
the total 142 million hectares of cultivable land in the country is still not
covered by irrigation, leaving majority of farmers dependent on monsoon. The
new scheme aims to ensure access to protective irrigation. It would guarantee
that State and district irrigation plans get prepared on the basis of
prevailing agro-climatic conditions and sources of availability of water in the
region.
Under PMKSY, States will get 75 per
cent Central grant while for the North Eastern States it would go up to 90 per
cent. The Government had earmarked Rs 1,000 crores for the scheme in the Budget
but it is understood that Rs 5,300 crores would be spent this fiscal. This is
expected to bring an additional 6 lakh hectares under irrigation, while five lakh
hectares will benefit from drip irrigation. Additionally, 1300 watershed
projects have been marked for completion.
Experts are of the opinion that
achievement of the target may not become a reality even in the next decade or
so, as it is practically impossible to accomplish this task due to various
factors, the most important being the availability of water. Though the project
has clearly demonstrated the Government’s eagerness to help the farming
community, the present situation of acute water scarcity in certain parts of
the country may be rather difficult to accomplish the target.
As is well known, agriculture
accounts for about 15 per cent of India’s economy and over 70 per
cent of the population depends on farming for a livelihood. While there is high
potential of agriculture and agro-based products for the country, at this
juncture it is an imperative need to increase production and productivity,
specially in regions where yields are quite low. This may only be achieved through
irrigation, which the Government now plans and claims to spread across the
country.
However, various studies have
revealed that groundwater levels have been declining in various parts of the
country, primarily across northern India, and the country may become a
water-stressed country within the next three to four years. Scientists at the
National Centre for Medium Range Weather Forecasting (NCMRWF) and their
collaborating agencies -- including the Indian Institute of Science, Bangalore
and Space Applications Centre, Ahmedabad -- found that the terrestrial water
storage (TWS), a measure of surface and underground water, decreased by one cm
per annum between 2003 and 2012. The new results are important because they
indicate a loss of TWS even in the absence of any significant changes in either
rainfall patterns of river water discharges.
According to the study of NCMRWF,
the decrease in water stored in lakes, reservoirs, rivers along with groundwater
is definitely a cause of worry as this may affect everything from power to
agriculture. The researchers used a pair of US-German satellites named GRACE
(Gravity Recovery & Climate Experience) that track subtle changes in
earth’s gravity on each other to estimate changes in surface and groundwater on
the planet.
Scientists at NASA space agency used
GRACE to estimate that the country’s north western granary States of Punjab, Haryana and Rajasthan had lost substantial amount
of groundwater by an average of 100 cm every three years. India’s
National Remote Sensing Agency too found that groundwater levels in the
Indo-Gangetic plain had been declining by about 3 mm per month between 2005 and
2010.
Experts are of the opinion that by
the year 2020 or even earlier there would be a genuine water crisis in many
regions of the country. Even now, the Cauvery, Pennar, Sabarmati, East-and West
flowing rivers are some of the basins of the country with scarcity conditions.
It may be mentioned here that while water availability of less than 1000 m per
capita is considered by international agencies as scarcity condition, in
majority of the river basins, present utilization is quite high in the range of
50-95 per cent of utilizable surface resources.
In this connection, one may mention
that the plan of linking the rivers across the country, specially the
Manas-Sankosh-Teesta-Ganga link in Assam. Bengal and Bihar
would not only provide large irrigation benefits to the three States but also
make available large quantities of surplus water for transfer to the southern States.
This would be the fifth inter link project while the first one – Ken-Betwa link
– is expected to begin this year. If these projects are properly monitored, the
irrigation potential of the country would hopefully steadily rise.
Delving into statistics, investment
in irrigation grew from 7.5 per cent in 2004-05 to only 7.7 per cent in
2013-14. Within this, the share of the Government actually declined from 6.7
per cent to 4.7 per cent while the private sector share increased from 7.8 to
8.6 per cent. Between 2004 and 2014, the Central Government provided over Rs
53,000 crores to the States for irrigation projects, according to a reply in
Parliament (April this year). But, out of 297 projects, 163 were running much
behind schedule, including some for over 20 years.
Thus it is quite obvious that apart
from lack of water availability, inefficiency in handling irrigation projects
and lack of financial resources have affected the much-needed spread of
irrigation facilities in the country. Importantly, the sheer lack of water has
prompted agricultural scientists to experiment cultivation of crops that
require less water, which is called dryland farming. There has been some
success on this front though the need for irrigation cannot be doubted for two
to three yields per annum.
It goes without saying that with the
launch of the new scheme, it is also necessary to bring about more efficiency
in completion of projects so that food grains output could be boosted. Moreover,
a deficient monsoon should not affect food grains production and agricultural
productivity. If the scheme is even partly successful, it would be a big boost
to the agricultural sector to offset the need for more food grains with an ever
expanding population in the coming years. ---INFA
