Indus River
Without the Indus waters, agriculture in Pakistan would be very uncertain, because there is not much rain. Even now when Pakistan is being rapidly industrialised, it needs its water resources, because much of its industry uses agriculture produce for its raw materials.  Almost all of the basin in Pakistan receives an overall rainfull of less than 15 inches, 60% of its area receiving less than 10 inches, while, 16% receives less than 5 inches.  The rainfull is not evenly distributed throughout the year but is concentrated during the monsoons.
