| Comments |
"In the agricultural sector, which is estimated to withdraw two-thirds of world water withdrawals and which accounts for 90% of total water consumption in the world (primary source) in the period from 1961 to 2004, crop yield per area
increased by a factor of 2.3, more than the rate of
population growth (2.0), and the total crop yield
increased by a factor of 2.4, even though the
area of cropland increased by only 10% and
harvested area increased less than that (ref 24)." |
