Abstract
This paper presents rigorous analysis of shortage of canal water supplies, crop water
requirements, and groundwater use and its quality in the command of Lower Bari Doab Canal,
Pakistan. The annual canal water supplies are 36% less than the crop water requirements. This
shortage further increases to 56% if actual canal supplies (averaged over last ten years) are
compared with the crop water requirement. The groundwater levels are depleting at the rate of 30 to
40 cm per year in most parts of the LBDC command and this tendency of lowering may increase in
future due to further increase in crop water requirements. The analysis of data for the last seven years
indicate that quality of groundwater in most parts of LBDC command is generally good (64% of the
area) or marginally acceptable (28%) for irrigation use. However, declining trends in groundwater
quality are visible and can create long term sustainability problems if proper remedial actions are not
taken well in time.
