Agriculture accounts for approximately what percentage of total world water use?

• A. 10%
• B. 50%
• C. 70%
• D. 30%

Answer: (C)

The main idea is understanding how water use is distributed globally, with agriculture consuming the largest share because irrigation draws in a large amount of freshwater. When global withdrawals are tallied, about seven-tenths of freshwater used each year goes to agriculture. That’s roughly 70%. The rest is split between industry and domestic use, with industry and households making up the smaller shares. Regional variations exist and definitions (like including green water vs. blue water) can shift the exact number, but 70% is the standard global estimate.
