WRI&DD > RKVY
The postulate that wherever there is
water, poverty will dissipate by itself is aptly demonstrated by flagship projects of Rahtriya Krishi Vikas Yojana
(RKVY) undertaken by WRI&DD which has envisaged to maximize Minor Irrigation Development by exploitation of surface
and ground water resources throughout the state for extending irrigation facilities to far flung areas where irrigation
water is scarce or not available as well as providing assured irrigation to increase cropping intensity. The target area
and objective of the RKVY is to address underlying constraints impeding agricultural productivity in remote and distant
areas where no other irrigation facilities could be provided and it will facilitate critical gap bridging as achieved in
pursuant to the targeted initiative of RKVY named "Bringing green revolution to the Eastern India" to cater to the
small and marginal farmers for their overall socio-economic development taking into consideration the State's agro climatic
conditions, natural resources and technology.
The state of West Bengal has diverse
physiographies and hydro-geological conditions and is dominated by small land holders and landless labourers
comprising several agro-ecological regions, make it conducive to grow a wide variety of crops comprising of fruits,
vegetables etc. The average rainfall in the State is about 1750 mm of which 1250 mm., occurs during June to September.
Instead of being uniform, the precipitation pattern in the State is found to register wide regional variations.
While the hilly Himalayan region receives the heaviest rainfall, ranging from about 2500 mm to 6000 mm. the Southern
districts in the plains receive on an average 1125 mm to 1875 mm. Among the districts in the plains, Bankura, incidentally
receives the lowest rainfall (1175 mm) and jalpaiguri the highest (3900 mm). But,West Bengal suffers from inadequate availability
of irrigation water, mainly because of its undulating topography, high surface runoff, and lack of surface storage facilities.
To remedy the situation, WRI&DD has designed RKVY format
to provide complete flexibility to the different Executive Engineers of the State to select, plan and execute projects
as per their priorities and adopted Minor Irrigation Structures such as Tube wells and Water Harvesting tanks, Surface flow minor
Irrigation schemes &Minor Irrigation Tanks (MIT) etc to create water resources for assured irrigation.
Non-availability of timely and adequate water for irrigation
is a serious constraint in achieving higher productivity and stability of farming; assured irrigation is the need of the hour. Though
the total rainfall in the State is satisfactory, its distribution over time and space is highly uneven. Therefore, rain water harvesting
and water use efficiency are critical in arid areas for increasing production and productivity in conjunction with ground water supplement
through tube wells where safe drawal is possible.
Department of agriculture,government of West Bengal decided to scale
up minor irrigation related interventions under RKVY to boost ongoing efforts. These interventions were prioritized as RKVY flagship scheme
with a total outlay of Rs.521.743, Rs.798.988, Rs.1300.00, Rs.1200.00 & Rs.2212.94 & Rs.2901.64 lakh during the years 2008-2009, 2009-2010,
2010-2011,2011-2012 , 2012-2013,2014-2015 respectively and Rs.1825.50 lakh has been assigned for the year 2015-16 for WRI&DD.
Among different types of irrigation schemes, minor, irrigation schemes
based on exploitation of surface water resources are the most popular schemes and have appropriately been adopted in large numbers in the State.
Such schemes have advantages as these can show quicker utilization of created potential. Since it is the priority to extend maximum benefits to
small and marginal farmers, it has been ensured that schemes are to be so located that 80% or more of the beneficiaries belong to small and marginal
Following MI structures have been adopted depending upon available natural
resources in agro-climatic regions, like geo-hydrological characteristics, soil texture and structure, land topography in accordance with the vision of RKVY.
Tube Wells have been proposed for those areas where stage of development is still low and safe drawal is possible.
Substantial progress has been made in the creation of minor irrigation related assets
by RKVY since its inception in the year 2007-08.Irrigation potential of about 38136 Ha has been created so far up to the financial year 2015-2016 against 2931 nos.
of various M.I schemes and irrigation potential of 1128 Ha has been proposed to be created during 2016-17.
