1. Name of the Project : -Diversion Channel Based Irrigation Project Nandurbar2. Sponsored by : - Jamsetji Tata Trust ( JTT)3. Date of starting : - April 2009.6. Financial Status :- a) Fund Received Till date :- 68,26,000/- b) Expenditure Till date :- 48,00,000/-
Scope in Nandurbar District –Nandurbar is one of the most backward tribal districts of Maharashtra. On thebasis of its physical features, Nandurbar District can be divided into two regions –plain area of Tapi river basin (Shahada, Taloda, Nandurbar and Navapur) andhilly areas of Satpuda (Dhadgaon and Akkalkuwa). Hill slopes are very steepleading to severe soil erosion during rainy season. People face water scarcity insummer, even for drinking. The main problems of the area are unemployment, lackof basic infrastructure, malnutrition, leading to seasonal migration. MaharashtraInstitute of Technology Transfer for Rural Areas (MITTRA) started the work fiveyears back, mainly for livelihood of these resource poor tribal through naturalresource management. Near about 11500 families have participated in land baseddevelopment programme. The main challenge was to provide irrigation tohorticulture and agriculture in non-monsoon, because of the geographicalcondition. Lift irrigation method which was tried, almost failed due to very highhead leading to more fuel consumption with less output. The matter was discussedwith the participant tribal. Along with few other innovative ideas like use ofdonkeys for water conveyance; the diversion channel based irrigation was the mainsuggested solution. There is great scope for expansion of this activity in Satpudahill ranges. There is need of integration of modern technique with traditionalmethod, community mobilization and financial supportIn hilly areas of Nandurbar district there is too much scope to develop such sitesand increase irrigation. There are considerable number of nalah and rivulets inthis area which flows through out the year with ample amount of water
. Pilot InitiativesConsidering importance and potential of this system, In October 2006MITTRA had taken work of development on one site in Belakundvillage of Akkalkua Taluka in Nandurbar district. This work hadbeen taken on pilot basis in order to revive traditional knowledge.There were five participant families with two hectare average landholding .The land had no irrigation facility. They were cultivatingonly rain fed crops like maize, jowar, millets, etc. MITTRA made participants aware of importance irrigationand motivated them to come and work together for construction ofimpounding structure, diversion channel and effective distribution ofwater. MITTRA had supplied 300 empty cement bags for impoundingthe water by constructing the temporary check dam. Twenty PVCpipes were provided for crossing the nallah. Thirty members form theparticipant families worked for five days for preparing the channeland two days for construction of the temporary check dam.
Objective of project-1.To increase the irrigation areas2.To assured the irrigation3.To mobillise the farmers for the proper waterdistribution system for irrgation.
Impounding structure-This is the concrete structure constructed by plumb concretework having the distance of according to the width of Nalawhich helpful to the harvest the water and diverted into thechannel.It is constructed with proper desing. These structureenables water level in the source to rise up certain desired heightso that it can diverted in the gravity channel to carry it to thefield for irrigation. The length and height of the structure mayvary according to each individual site.
Land Development-This constitute treatment of the land so as to improve its productivity andfertility. It includes mainly soil conservation measures such as contourbunding, Farm bunding , Stone plugging, Gully plug and outlets for floodwater.This enables to reduce soil erosion, increases soil moisture. Humuscontent and soil depth. Total length of farm bunding or contour bunding forone hectare will be 250 metres The cross section for these bund will be 62metre. Stone bunding has also been proposed if stone is available. Crosssection for stone bund will be 27 metre.and its length per hectare will be500.00 metres. Forest tree species will be planted on newly constructedfarm bund with consulting the farmer.
Channel Development-These involves excavation and development of water conveying channel.Facilities and arrangements for fly over to cross river or any majorNALLA`S.Its have been proposed seven masonry column. Onedistribution chamber has also been proposed in each site for effectivedistribution . These PVC pipe would rest on the column through whichwater could be conveyed from one bank to another. No of PVC pipe ,no ofmasonry column and no. distribution chamber may vary according to eachindividual site.
Improved Agriculture –The main crops are maize, groundnut, and with the currentagricultural practices the average yield of maize is 3.5 quintal per acrewhile the yield of groundnut is 4 quintal per acre. There is scope toincrease the productivity by 7 quintal per acre in maize and 8 quintalper acre for groundnut.During the rabbi season MITTRA hassupported the improved seed of Gram,Maize and vegetable crop likeOnion, raddish,Brinjal and Tomato. After the implementation of DBIScheme farmers has introducing new crop wheat for cultivation.
