water resources. Demand of water
from various sectors of economy
(urban, industry, and agriculture) is
rapidly increasing while the supply
of freshwater is constant. As a
regular source of fresh water, India
receives nearly 4,000 BCM (Billion
Cubic Metre) of precipitation
(rainwater, snow, hails etc.) per
year, but approximately 80 percent
of this is received during monsoon
season (June-September) only. This
results in huge run-off losses during
monsoon and calls for irrigation
investments for rest of the year.
Due to limited water harvesting
infrastructure, only less than one-
third of this precipitation can be
utilised. The per-capita storage
capacity is India is low as compared
to other countries. Annual utilisable surface and
groundwater resources are estimated to be 690
BCM and 431 BCM respectively. Average flow of
rivers is estimated to be 1869 BCM. Groundwater
is a replenishable source which gets nearly 74
percent recharge from rainfall and the rest is
contributed by canals, ponds, reservoirs and other
water conservation practices. Agriculture sector
uses 89 percent of the groundwater for irrigation,
while 11 percent is consumed in the domestic and
industrial uses. Overall, the agriculture sector is the
largest freshwater user in the country accounting
for almost 85 percent of the total water usage.
This is mainly due to cultivation of water intensive
crops such as rice, wheat, sugarcane and cotton,
and very low irrigation efficiency. The common
pool nature of groundwater and the difficulty of
observing it directly make the resource challenging
to monitor and regulate. Hence, unsustainable
extraction levels that exceed natural recharge
rates are depleting groundwater resources rapidly.
Water table is receding at an alarming rate of
0.3 meter per year. The Central Groundwater
Board has categorised 16.2 percent of the total
assessment units (Blocks, Mandals or Talukas)
numbering 6,607 as ‘over-exploited’. Additional 14
percent units have been categorised at ‘critical’ or
‘semi-critical’ stage. However, if rainfall is collected
and managed properly with the help of rainwater
harvesting and artificial recharge structures
for augmentation of ground and
surface water, this can reduce
dependence on groundwater to
the tune of about 500 BCM out of
the total annual water requirement
of 1200 BCM for all sectors. The
unsustainable groundwater use
necessitates demand management
and supply augmentation
measures for increased water use
efficiency in agriculture sector. In
this context, agricultural water
management is an imperative in
the country. Although irrigation is
a major component in agricultural
water management, it also includes
soil, land, and water conservation
practices; improving the efficiency
of water use in irrigation; and
technologies for lifting, storing
and conveying water. Further, the National Water
Policy 2012 recommends conservation of existing
water bodies, rivers, river corridors, etc.
Managing Water at Source
Soon after independence, Government of India
pushed ‘Creation and Expansion of Irrigation
Facilities’ into its top agenda to mitigate
recurrent famines and hunger. During initial
years, development of canal irrigation remained
a priority area in which Government of India
invested profusely through various irrigation
projects across the country. As a result, the area
irrigated by canals increased from 71 lakh hectares
during 1950-51 to 144 lakh hectares during 1980-
81; and further reached a peak level of 173 lakh
hectares by the year 1991-92. However, during
1980s groundwater irrigation expanded at a much
faster rate than canal irrigation. Consequently,
area under canal irrigation not only stagnated but
declined and hovered around 160 lakh hectares
during 2011-12 to 2014-15, which is 10 lakh
hectares less than what was achieved 20 years
back. As a result, the share of canal irrigation in the
total irrigated area has declined from 37.5 percent
in 1984-85 to 23.43 percent in 2014-15. There are
some specific reasons for making canal irrigation
out of favour : low reliability and reduced flow
of water at source; poor maintenance of canal
and tributaries; poor utilisation of the irrigation

been substantial disparity in rainfall, it varies
from less than 100 mm in western Rajasthan to
Kurukshetra July 2022 46
more than 2500 mm in north-eastern part of the
country. Such condition necessitates formulation
of different set of strategies to manage irrigation
for whole year.
It is generally observed and well recognised that
Indian farmers use 2 to 4 times more water to
produce a unit major food crop than in China or
Brazil. Hence, wise and efficient use of water is a
must for sustainable development of agriculture
sector and national food security. In this context,
two crops–rice and sugarcane–deserve special
attention as only these two crops consume almost
60 percent of the country’s irrigation water.
Technologies are available which can produce the
same output with nearly half the irrigation water
in these two crops. For instance, around 3,000
litres of water is used to produce one kilogram of
paddy grain under the traditional flood irrigation.
Whereas, under drip system of irrigation the
requirement can be slashed to just 842 litres. New
technologies, such as Direct Seeded Rice (DSR) and
System of Rice Intensification (SRI) can also save
25 to 30 percent of water compared to traditional
flood irrigation. In sugarcane, trench farming has
been found very effective in saving water. About
300 farmers in Uttar Pradesh have been able to
reduce water usage using trench farming and
they have saved an estimated 60 million litres of
water during 2019-2021. State Governments need
to motivate farmers for adoption of scientifically
designed cropping patterns to ensure optimum
utilisation of water. Scheduling of irrigation is
another simple and effective methodology to
save water and energy. In the process, the correct
frequency and duration of watering is determined
on the basis of moisture in the soil and stage of
the crop growth. About 35-40 percent water can
be saved by scheduling of irrigation along with
significant reduction in fertilizer use. Moisture
sensors and automated irrigation systems which
can be controlled by a farmer using smart phone,
will help in deciding the time and amount of
irrigation to be carried out.
The traditional methods of irrigation, mainly
flood irrigation, have low irrigation efficiency
(38 percent) due to excessive seepage loss and
inequitable and untimely supplies. Adoption of
water saving technologies such as sprinkler and
drip irrigation systems have proven extremely
effective in not just water conservation but
also lead to higher yields. It has been observed
that among various methods of irrigation, drip
irrigation has achieved highest application
efficiency of 90 percent with over-all efficiency
ranging between 80-90 percent. New agronomic
practices such as raised bed planting, ridge-furrow
method of sowing, sub-surface irrigation and
precision farming are also helpful in increasing
irrigation efficiency. In this context, Government
of India has launched new policies and schemes to
increase area under irrigation and enhance water
use efficiency.
Pushing Irrigation to New Heights
Among various schemes launched by Central
Government, Pradhan Mantri Krishi Sinchayee
Yojana (PMKSY) is the most comprehensive one
aiming at protective irrigation for all agricultural
farms in the country. Launched in 2015-16, it has
the following 4 major components.
• Accelerated Irrigation Benefit Programme
(AIBP),
• Har Khet Ko Pani (HKKP),
• Per Drop More Crop (PDMC), and
• Integrated Watershed Management
Programme.
AIBP covers major to medium irrigation projects
that involve an area of more than 2,000 hectare.
During 2016-17, 99 on-going major/medium
irrigation projects have been prioritised in
consultation with States for completion in phases.
Out of this, 44 projects have been reported to be
completed/almost completed and an additional
irrigation potential of 21.45 lakh hectare has
been reported to be created by these projects.
HKKP-Command Area Development and Water
Management (CADWM) programme aims to
utilise created irrigation potential as soon as
project is completed. Further, its objectives
include improving water use efficiency; increasing
agricultural productivity and production; and
bring sustainability in the irrigated agriculture in
a participatory environment. So far, about 14.85
lakh hectare cultural command area has been
developed. Under HKKP-Surface Minor Irrigation
scheme, the total number of sanctioned projects
are 6,213 and 3,098 schemes have been completed

from various sectors of economy
(urban, industry, and agriculture) is

Due to limited water harvesting

of 1200 BCM for all sectors. The
unsustainable groundwater use
necessitates demand management
and supply augmentation
measures for increased water use
efficiency in agriculture sector. In
this context, agricultural water
management is an imperative in
the country. Although irrigation is
a major component in agricultural
water management, it also includes
soil, land, and water conservation
practices; improving the efficiency
of water use in irrigation; and
technologies for lifting, storing
and conveying water. Further, the National Water
Policy 2012 recommends conservation of existing
water bodies, rivers, river corridors, etc.
Managing Water at Source
Soon after independence, Government of India
pushed ‘Creation and Expansion of Irrigation
Facilities’ into its top agenda to mitigate
recurrent famines and hunger. During initial
years, development of canal irrigation remained
a priority area in which Government of India
invested profusely through various irrigation
projects across the country. As a result, the area
irrigated by canals increased from 71 lakh hectares
during 1950-51 to 144 lakh hectares during 1980-
81; and further reached a peak level of 173 lakh
hectares by the year 1991-92. However, during
1980s groundwater irrigation expanded at a much
faster rate than canal irrigation. Consequently,
area under canal irrigation not only stagnated but
declined and hovered around 160 lakh hectares
during 2011-12 to 2014-15, which is 10 lakh
hectares less than what was achieved 20 years
back. As a result, the share of canal irrigation in the
total irrigated area has declined from 37.5 percent
in 1984-85 to 23.43 percent in 2014-15. There are
some specific reasons for making canal irrigation
out of favour : low reliability and reduced flow
of water at source; poor maintenance of canal
and tributaries; poor utilisation of the irrigation
Pradhan Mantri Krishi Sinchayee
Yojana (PMKSY) is the most
comprehensive scheme launched
in 2015 to increase irrigation
facilities, promote micro-irrigation
and support development of
water conservation and recharge
structures. State Governments have
also implemented their own specific
irrigation schemes. In addition
to Ministry of Jal Shakti, Central
Ground Water Board is also working
towards aquifer rejuvenation, water
conservation and artificial recharge.
Mahatma Gandhi National Rural
Employment Guarantee Scheme
(MGNREGS) is also significantly
contributing in water conservation
efforts across rural India.

potential created; and an increase in cultivation
of water intensive crops; and adoption of water
intensive practices. Presently, canals are irrigating
those lands, which have large plains, fertile soils
and perennial rivers. The plains of north India are
mostly canal irrigated.
Meanwhile, many major (Cultivation Command
Area, CCA, more than 10,000 hectare), medium
(CCA 2,000 – 10,000 hectare) and minor (CCA
less than 2,000 hectare) irrigation schemes were
launched to improve status of irrigation in India.
Water resources development and management
are planned, funded, executed and maintained
by the State Governments as per their own
state-specific priorities and resources, while
Government of India supplements /supports the
efforts of State Governments by providing financial
and technical assistance through various schemes
and programmes. With collective and concerted
efforts at various levels, utilised irrigation potential
(surface and groundwater combined) has reached
to 87 million hectare, while ultimate irrigation
potential touched 140 million hectare. As per latest
estimates (2018-19), against total agricultural land
of 1,80,888 thousand hectares, the cultivated land
in the country was 1,53,888 thousand hectares,
out of which net 71,554 thousand hectares was
irrigated. Rest of the cultivated area, nearly 54
percent, is rainfed; that is, depends on rainfall
for irrigation. Even if ultimate irrigation potential
is achieved, nearly 31 percent of cultivable area
will remain under rainfed condition. There has
been substantial disparity in rainfall, it varies
from less than 100 mm in western Rajasthan to
Kurukshetra July 2022 46
more than 2500 mm in north-eastern part of the
country. Such condition necessitates formulation
of different set of strategies to manage irrigation
for whole year.
It is generally observed and well recognised that
Indian farmers use 2 to 4 times more water to
produce a unit major food crop than in China or
Brazil. Hence, wise and efficient use of water is a
must for sustainable development of agriculture
sector and national food security. In this context,
two crops–rice and sugarcane–deserve special
attention as only these two crops consume almost
60 percent of the country’s irrigation water.
Technologies are available which can produce the
same output with nearly half the irrigation water
in these two crops. For instance, around 3,000
litres of water is used to produce one kilogram of
paddy grain under the traditional flood irrigation.
Whereas, under drip system of irrigation the
requirement can be slashed to just 842 litres. New
technologies, such as Direct Seeded Rice (DSR) and
System of Rice Intensification (SRI) can also save
25 to 30 percent of water compared to traditional
flood irrigation. In sugarcane, trench farming has
been found very effective in saving water. About
300 farmers in Uttar Pradesh have been able to
reduce water usage using trench farming and
they have saved an estimated 60 million litres of
water during 2019-2021. State Governments need
to motivate farmers for adoption of scientifically
designed cropping patterns to ensure optimum
utilisation of water. Scheduling of irrigation is
another simple and effective methodology to
save water and energy. In the process, the correct
frequency and duration of watering is determined
on the basis of moisture in the soil and stage of
the crop growth. About 35-40 percent water can
be saved by scheduling of irrigation along with
significant reduction in fertilizer use. Moisture
sensors and automated irrigation systems which
can be controlled by a farmer using smart phone,
will help in deciding the time and amount of
irrigation to be carried out.
The traditional methods of irrigation, mainly
flood irrigation, have low irrigation efficiency
(38 percent) due to excessive seepage loss and
inequitable and untimely supplies. Adoption of
water saving technologies such as sprinkler and
drip irrigation systems have proven extremely
effective in not just water conservation but
also lead to higher yields. It has been observed
that among various methods of irrigation, drip
irrigation has achieved highest application
efficiency of 90 percent with over-all efficiency
ranging between 80-90 percent. New agronomic
practices such as raised bed planting, ridge-furrow
method of sowing, sub-surface irrigation and
precision farming are also helpful in increasing
irrigation efficiency. In this context, Government
of India has launched new policies and schemes to
increase area under irrigation and enhance water
use efficiency.
Pushing Irrigation to New Heights
Among various schemes launched by Central
Government, Pradhan Mantri Krishi Sinchayee
Yojana (PMKSY) is the most comprehensive one
aiming at protective irrigation for all agricultural
farms in the country. Launched in 2015-16, it has
the following 4 major components.
• Accelerated Irrigation Benefit Programme
(AIBP),
• Har Khet Ko Pani (HKKP),
• Per Drop More Crop (PDMC), and
• Integrated Watershed Management
Programme.
AIBP covers major to medium irrigation projects
that involve an area of more than 2,000 hectare.
During 2016-17, 99 on-going major/medium
irrigation projects have been prioritised in
consultation with States for completion in phases.
Out of this, 44 projects have been reported to be
completed/almost completed and an additional
irrigation potential of 21.45 lakh hectare has
been reported to be created by these projects.
HKKP-Command Area Development and Water
Management (CADWM) programme aims to
utilise created irrigation potential as soon as
project is completed. Further, its objectives
include improving water use efficiency; increasing
agricultural productivity and production; and
bring sustainability in the irrigated agriculture in
a participatory environment. So far, about 14.85
lakh hectare cultural command area has been
developed. Under HKKP-Surface Minor Irrigation
scheme, the total number of sanctioned projects
are 6,213 and 3,098 schemes have been completed
Kurukshetra July 2022 47
upto March, 2020. During 2017-20, Surface Minor
Irrigation (SMI) scheme could achieve irrigation
potential of 1.20 lakh hectare. HKKP also runs
a specific program for repair, renovation and
restoration of water bodies. Out of 2,319 water
bodies approved, 1,359 have been renovated as
of March, 2020 with net irrigation potential of
0.5283 lakh hectare. Watershed Development
Programme, running across the country, has
successfully and significantly improved the
availability of surface and groundwater in project
areas. Since 2014-15, 7.09 lakh water harvesting
structures have been created/rejuvenated and an
additional area of 15.17 lakh hectare was brought
under protective irrigation up to third quarter of
2020-21. The programme has also led to increase
in productivity, vegetative cover, livelihood
opportunities and household incomes causing
socio-economic transformation. ‘Per Drop More
Crop’ component of PMKSY focuses on enhancing
water use efficiency at farm level through micro-
irrigation systems (Drip, Sprinkler, Fogger etc.).
This component also supports micro level storage
or water conservation/management activities to
supplement source creation for micro-irrigation.
During 2015-16 to March, 2021, micro-irrigation
has achieved an impressive coverage of 53.69 lakh
hectare on All-India basis. In addition, 4.84 lakh
micro level water harvesting/secondary storage
structures have been created to supplement
the micro-irrigation. To provide impetus to
micro-irrigation, Government of India created
a special Micro-Irrigation Fund with a corpus
of Rs. 5,000 crore during 2018-19 with NABARD
as implementing agency. This fund facilitates
the States in further mobilising the resources to
provide additional incentives to farmers beyond
the provisions available under PMKSY-PDMC. This
fund is facilitating to bring another 12.83 lakh
hectares area under micro-irrigation in the States
of Andhra Pradesh, Gujarat, Tamil Nadu, Haryana,
West Bengal, Punjab and Uttarakhand. In view of
growing interest of many other States in micro-
irrigation, Government of India, in its budget
for 2021-22, has doubled the initial corpus of
Rs 5,000 crore by augmenting in by another Rs 5,000
crore. In addition to efficient use of water, micro-
irrigation ensured higher productivity, reduction
in labour cost, saving in power consumption,
and reduction in fertilizer use. Micro-irrigation
techniques help farmers to get better returns due
to higher productivity, high quality of produce and
savings on other inputs.
Several State Governments also acted
simultaneously and designed their own
participatory irrigation management programmes.
In the State of Bihar, interventions by ‘Jal Jeevan
Hariyali Abhiyan’ have increased the number
of water structures (over 2,600 checks dams
constructed); developed plantations (over
41,600 plantations); and enhanced the use of
micro irrigation significantly. In Chattisgarh,
construction of small dams, canals and dykes
resulted in additional groundwater recharge. The
State of Jharkhand launched a special scheme,
‘Neelambar Pitambar Jal Samridhi Yojana’ in May,
2020 for creation of field bunding, rejuvenation of
nalas and construction of soak pits. As a result,
currently, on an average five schemes of water
conservation are running in every village in the
Lohardaga district of Jharkhand. ‘Birsa Munda
Krishi Kranti Yojana’ in Maharashtra has increased
micro-irrigation area and took up construction of
new wells and ponds along with repair of unused
wells. Now, irrigation water is available in water
scarce tribal areas.
Conservation is Another Key
Among various water conservation techniques,
mulching is a simple, ‘easy-to-do’, effective and
comparatively low cost means that reduces water
loss by checking evaporation from soil surface.
Mulch is any covering material, either organic
or inorganic, applied on soil surface to create
a barricade which does not allow escape of soil
moisture. The moisture is conserved for many days
thus reducing the demand of irrigation during the
period of crop cultivation. Additionally, mulching
improves soil structure, reduces soil salinity and
also controls weeds. Various types of plastic
mulches are available in market, but mulching can
also be effectively done by using agri wastes such
as wheat straw, gross clippings, leaf debris, etc.
Plastic film lining has proved to be an effective tool
against loss of water through seepage in canals,
ponds and reservoirs. By reducing seepage losses
up to 100 percent, it improves water availability
over a longer period of time for irrigation purposes.
It also prevents soil erosion and is highly useful in
porous soils where water retention in ponds in a
