Less than \(2000\,\mathrm{m}^3\)/person/year
- C.
Less than \(2300\,\mathrm{m}^3\)/person/year
- D.
Less than \(2500\,\mathrm{m}^3\)/person/year
Show answer & explanation
Correct answer: A
Concept
The Falkenmark indicator measures annual renewable freshwater availability per person. It uses fixed per-capita thresholds to distinguish water stress, water scarcity, and absolute scarcity.
Application
On this scale, water stress begins when annual availability falls below 1,700 cubic metres per person. Among the offered values, the matching limit is less than 1,700 m³/person/year.
Cross-check
The lower bands provide a cross-check: below 1,000 m³/person/year indicates water scarcity, and below 500 m³/person/year indicates absolute scarcity. The other offered limits—2,000, 2,300, and 2,500—are all above the conventional water-stress boundary.
Result
Therefore, the applicable limit is less than 1,700 m³/person/year.
