What is the limit of water availability for a region to be classified as a water-stressed region?

ALess than 1700 cubic metres ✓ Correct

BLess than 2000 cubic metres

CLess than 2300 cubic metres

DLess than 2500 cubic metres

Correct answer: (A) Less than 1700 cubic metres

Explanation

A region is termed water-stressed when annual per-capita availability falls below 1700 cubic metres, the Falkenmark benchmark.

The 2000 cubic metre figure sits above this threshold and marks no recognised stress category.

The 2300 cubic metre level likewise describes comfortable availability, not stress.

The 2500 cubic metre value is far higher and reflects abundant supply.

Below 1000 cubic metres the same indicator labels a region water-scarce.

Absolute scarcity is reached under 500 cubic metres per person per year.
