Drought classification MCQ — 1 Practice Questions with Answers

Explanation

In the India Meteorological Department classification, drought is judged by the shortfall of actual rainfall from normal rainfall. A severe drought is associated with a rainfall deficiency exceeding 50% of normal. A deficiency of 20% or 25% is too low for the severe category and is closer to the threshold at which rainfall departure begins to be watched seriously. A 40% shortfall is substantial, but the severe drought cut-off in this question is above 50%. Therefore, 50% is the correct figure retained from the key.
