This line chart and table illustrate water use construction and water comsuming different between brazil and congo.

From the line graph ,we can easily see the difference between agriculture water use,industial use and dometic use.
The agriculture water use is  the highest all time,industial use is between agriculture use and dometic use. It is clear to see that, those 3 ways both growed slowly before 1950.After it ,agriculture use has a dramastic increasing and domestic use induce not too signifitily.

We can know it from the table , the brazil has larger population than congo ,reach to 176 million and 5.2 million.But the irrigated land is changed,brazil only has 21.500km2 however congo has 100km2 .Water consumption per person in brazil has 359m3. For the congo,there is only 8m3.

In my conclusion,the global water use by secter from 1950 to 2000 has a signifitily increasing.From table we can know brazil has larger poplulation and lower irrigated land than congo,but water consuming of per person over congo a lot.
