A Users Friendly Decision Support Tool to Promote Conjunctive Use in Canal Command
There is hardly any evidence about adoption of conjunctive use practice in India mainly due to tremendous difference in cost of canal water and groundwater. In order to convince farmers about conjunctive use and its economical benefits, a users friendly decision support tool is developed both in Hindi and English languages using Visual Basic platform. This interactive tool calculates: (ⅰ)annual fixed and operational costs of irrigation from tubewell and canal; (ⅱ) yield and total cost of produce; (ⅲ) excess expenditure incurred in tubewell irrigation over canal irrigation; and (ⅳ) required yield increase to compensate additional cost of irrigation from tubewell. The tool was demonstrated among water users for three situations: (ⅰ) own tubewell; (ⅱ) renting pumping sets to run tubewells ; and (ⅲ) purchasing water from tubewell owners in the command of RP Channel V of Patna Main Canal under Sone Command in India. The results reveal that conjunctive use option can be propagated provided water users are convinced about yield improvement resulting in economic benefits, which compensate the additional cost of irrigation. Analysis showed that compared to owning tubewell, water purchasing is the most economical option followed by getting only pumping sets on rent basis to run tubewells for irrigation.
