(C)    SCHEMES PROPOSED UNDER "STATE PLAN"

I.Scheme of Extensive Renovation & Modernisation of Traditional Irrigation Systems of Ahars-Pynes & Tanks in South-Central Bihar under "Mukhya Mantri Ahar-Pyne Yojna":

a.    Background :

Text Box:  
 
Much prior to the present day modern irrigation storage/ diversion and distribution schemes based on the modern Water Resource Engineering concepts, there existed a well-knit indigenous traditional water harvesting (Ahars & Tanks) and irrigation distribution (Pynes) systems in all the districts of South & Central Bihar. There is historical account of their existence since Mauryan period (327–297 BC) though they received extensive expansion during the Sultanate and Mughal period (1100–1800 AD).

‘Ahar’, ‘Pynes’, ‘Bunds’ or "Tanks" are indigenous systems of rainwater conservation, storage and distribution. They can be scientifically described as watershed management systems of excess rainfall. There are statistical and historical account of their evolution, as well as maintenance rules mentioned in Kautilya’s “Arthshashtra”, and descriptions of Francis Buchannan (1810–11), W.W. Hunter (1876) and various district Gazetteers of British Bengal Presidency. Pynes start from rivers, streams and even from upstream “ahar or bundhs”. Pynes also terminate in ahars/bundhs (reservoirs) irrigating the command in head and draining in the tail. Ahar–pyne systems are in series from upper to lower catchments of streams. Unlike medium and major irrigation systems of diversion weirs/ barrage/ dams and canals, these traditional system catch the run–off of the river, divert/store them in the ahar/ bundhs and irrigate in the immediate vicinity. Over and above, they also recharge ground water of the adjoining areas. Thus there is integrated watershed management of surface water of the streams by harvesting the rain water through pynes; storing the run–off in reservoirs of ahars / bandhs; indirectly recharging the ground water; irrigating the command in the vicinity of these structures; draining the surface run–off to lower ahars/bandhs; mitigating the flood peaks of streams by distributing flood discharge through pynes, apart from multiple other uses as pisciculture, aquaculture, meeting domestic and livestock drinking water needs.

          For pynes taking off directly from streams in milder slope areas, farmers used to construct earthen bundhs across the river/streams in the down stream of the pynes. It helped diversion of run-off of the river into the pyne. With increased flood discharge, earthen bundhs break and pynes in the down stream get increased discharge. Thus the series of ahar/pyne worked.

b.  Project Rationale:

The level of protection provided by the ahar- pynes system can be gauged from the fact that old Gaya district, where the system reached its highest level of development, remained practically immune to famines while rest of India suffered. In 1866, the year of the Orissa Famine, in 1973-74 during the Bihar Famine caused by untimely rain, and during the famine of 1896-97, the then Gaya district required practically no relief. This immunity began to disappear once these irrigation works began to deteriorate. There were several years of scarcity in the 1930s. Old Gaya district, in particular Nawadah subdivision, was in the grip of severe drought and famine in 1950-52 and 1957-59. The famine of 1966 struck Gaya district with the same severity as it struck other districts of Bihar. Today, parts of Gaya are regarded as drought-prone areas. Gaya district was also immune to floods in the heyday of these irrigation structures. Off late this immunity too has been lost.

In Munger and Bhagalpur Divisions, the major sources of irrigation and potable water were large reservoirs and an extensive canal system. Perhaps the biggest earthen dam in Bihar was the Kharagpur reservoir built by the maharaja of Darbhanga in 1870. The reservoir irrigated an area of over 729 ha. Outside the area irrigated by the Kharagpur canals, a system of gilandazi bunds or dhar bunds was used. Dhar bunds were basically embankments across hill streams. They were constructed at the expense of the estate by the jeth-raiyats (headmen) of the villages because of frequent damages caused by floods.

 

Irrigation Potential of Traditional Irrigation Systems:-

The irrigation potential of these traditional schemes vis–a–vis potential of medium and minor schemes are presented in the table below:

                                                                                         (Figures in Lakh Ha.)

It is evident from the above table that utilizable potential of these schemes is of the order of about 40% of the total surface M.I potential and hence they need utmost attention to sustain the envisaged 4% agriculture growth projected for 11th five year plan of the country. Also as the cost of restoration of lost potential of these systems is only about one third of the cost of potential creation for medium and major irrigation schemes, they need immediate attention. Realizing the importance of these traditional irrigation systems as an important infrastructure for rapid development of this nation and sustaining the envisaged growth rate of agriculture, Ministry of Water Resources launched pilot project of “Repair, Renovation and Restoration of Traditional Water Bodies directly linked to Agriculture” from January’ 2005 with a plan outlay of Rs. 300 crore to be shared by Centre and state in 75 : 25 ratio. However, Bihar could get only six schemes sanctioned with estimated cost of Rs. 4.60 crores only whereas southern states of Andhra Pradesh, Karnataka and Tamil Nadu together got 645 schemes sanctioned.

Hence, there was urgent need to pose schemes of Extensive Renovation and Modernisation (ERM) for restoration of pristine glory and efficacy of these schemes. With this urgency in mind the Department has prepared this project 

 

II. Medium Irrigation (Surface Water Gravity Flow) Schemes :-

 

 

 

III. Ground Water (Exploratory T/W / Artificial Recharge) Schemes :-

": A sum of Rs. 100.00 lakh has been earmarked in 2007-08's budget under the unit "Survey of Ground Water". This amount will be used in Survey and Investigation of Ground Water to ascertain it availability in different parts of state. This will be done through drilling and developing "Investigatory" tubewells. Pilot schemes for "Recharging of Ground Water" will also be taken up under this head.

 

 

 

 

 

 

 

 

(a) Project of Restoration and Rehabilitation of Ahar and Pynes: A project of restoration and rehabilitation of 75 Ahar and Pynes is being prepared. This project is scheduled to be executed in financial year 2007-08.

 

(b)          Project of Restoration and Rehabilitation of Old State Tubewells: A project of restoration and rehabilitation of 500 old state tubewells is also proposed to be executed in the financial year 2007-08 under state plan. Priority will be given to the state tubewells falling in the Command Area of Sugar Mills.

 

(c) Project for "Planning Survey Investigation" of New Medium Irrigation (Surface Water Gravity Flow) Schemes: A budgetary provision of Rs. 200.00 lakh has been made under the unit "Survey of Surface Water". This amount will be utilised in Planning, Survey, Investigation and Formulation of new Medium Irrigation (Surface Water Gravity Flow) Schemes.

 

(D)    PROJECT UNDER "BHARAT NIRMAN YOJNA"

A sum of Rs. 222.00 lakh has been provided for centrally sponsored "Bharat Nirman Yojna". Under this project two water bodies of Jamui district and one water body of Nalanda district has been selected for repair, restoration and rehabilitation. The schemes have been given sanction by the Ministry of Water Resources, Government of India in January-2007, schemes are to completed in the financial year 2007-08.
