Description Not Available
The present study employs regional climate model projections for assessing the impact of root-zone
water balance and groundwater levels using crop and groundwater models. The projections from
Hadley Regional Model 3 (HRM3) for A1B scenario showed an increase in temperature and rainfall
(RF) of 1.8 W
C and 328 mm, respectively, during mid-century (MC) (2021–2050) for Indian central
Punjab. The respective increase in values for the end of century (2071–2098) would be 4.4 W
C and
486 mm, compared with present time slice (PTS) (2000–2010). In future, irrigation requirement would
reduce, because of increased RF and decreased transpiration from cropped area owing to a
shortening of crop duration of rice-wheat cropping system with temperature. The reduced irrigation
need in future would decrease groundwater withdrawal resulting in the rise of groundwater level
