This document provides details of a diversion-based irrigation project located in Jalpaiguri District, West Bengal. The key points are: 1) The project diverts water from the Diana River through a combination of open channels and pipes covering 430 hectares of land across 13 patches with different land uses. 2) Project components include 3 diversion weirs, 1 sedimentation chamber, 1 inspection chamber, 3.3km of pipeline, and 19km of open channels to irrigate 1160 beneficiary families. 3) The project aims to improve livelihoods, increase cropping intensity, and reduce distress migration by providing reliable irrigation to agricultural lands currently dependent on uneven canal water distribution and monsoon rains

15. Hold backs…
 Nature of the project
 Difficulty to get all the implements within desired period
and of desired specification in such a remote place
 No Objection Certificate from the forest department
 Unrest politics

16. Strategies
 Disclosing budget true copy to all stakeholders
 Inauguration involving main stream stakeholders
 Starting the down stream village portion first to create
pressure on Forest Dept.
 Putting Forest Protection Committee forward
 Repetitive visit along with the villagers to all political
platforms
 Decision maker’s visit to DBI site
 Persuasion of forest agenda by elected public
representatives

21. Livelihood promotional activities in
the command area
 System of rice/root intensification (no. of farmers):
 Khariff Paddy- 260
 Wheat- 200
 Maize- 50
 Mustered- 1
 Livelihood Planning exercise with 50 women SHGs
 Vermicompost beds: 358

22. Carbon Footprint context
•Total Area = 428 Ha.
= 428000 sq. m
•Water requirement (During rabi) = 2140000 m (Water requirement @1.5 ft)
= 2140000000 Ltr.
• Discharge of most commonly used pump (Type: Centrifugal self priming ,
Size: 3”X3”) = 550 Ltr./Min.
•Therefore,
• Total time (for such pump) = 64848.5 hr.
• Diesel to be burnt = 48636.4 Ltr. (When, diesel requirement for such
pump = 0.75ml/ Hr.)

23. Contd.
• Rate CO2 emission =2.7 Kg/Ltr. Of diesel (Ref: http://timeforchange.org/what-is-a-carbon-footprint-definition)
• Therefore,
-Quantity of CO2 possibly could have emitted = 131.32 ton. (approx)
In one year (Rabi season) we can restrict this
amount of ‘C’ emission
Considering the life of this DBI project=30years
Total reduction in CO2 emission=3939.6 ton
