Description This study deals with resource economics of groundwater irrigation in Karnataka.
Field data were collected from 30 sample farmers each (1) following drip irrigation for
narrow spaced crops; (2) following drip irrigation for broad spaced crops; (3) sharing
their groundwater well with their brothers; (4) who have recharged their borewell and 5.
Control farmers for 2012-13 from water scarce Eastern and Central Dry agro-climatic
Zones of Karnataka. The annual reciprocal negative externality in borewell irrigation was
the highest for farms using drip irrigation for narrow spaced crops (Rs. 25223), followed
by farms with borewell recharge (Rs.3386) and for farmers sharing well water (Rs. 1293).
The net return per rupee of cost of irrigation was the highest for farmers sharing well
water (Rs. 10.83) followed by farmers recharging their borewell (Rs. 8.17). Drip
irrigation shifted marginal productivity of groundwater by Rs. 4335 per acre inch from
threshold level of Rs. 3814 per acre inch. Due to on-farm borewell recharge the years of
successful functioning of borewells was 26 years yielding annual net return of Rs
1,97,583 per well. Drip irrigation conserved groundwater and farmers did not expand
their area irrigated Hence Jevons paradox is disproved. Pontryagin’s optimal groundwater
extraction demonstrated that farmers who recharged borewells can extract groundwater
for 25 years, while farmers who share water, can extract for 45 years. Net return per
rupee of cost of irrigation and net return per functioning well were higher by 50 per cent
and 16.5 per cent respectively for shared well farmers in comparison with control farms.
