The given pie chart shows world water consumption according to sector in the year 2000 while the line graph compares changes in water use from 1900 to 2000.
Overall, it is clear that agriculture is by far the biggest consumer of water globally.
Although all given sectors increased their water use over the 20th century, the rise was particularly dramatic in farming.
Looking in more detail at the data from 2000 in the pie chart, agriculture accounted for a massive 70% of global water consumption.
Industry was the second biggest water user but the figure was much lower at just under a quarter.
Households used only 6% and a tiny fraction was for drinking.
In terms of the changes over time, a dramatic increase is evident.
In 1900, just over 500 km3 of water went to farms and barely 100 km3 to industry and homes.
Over the next 100 years, agricultural consumption SOARED to 4000km3.
While the figures were much lower for domestic and industrial use, both started to go up from the 1970s.
