Droughts can precipitate a cascade of other disasters. Which of the following is NOT listed as a potential disaster directly resulting from a drought?

AWidespread famine.

BThe outbreak of epidemics.

CIncreased soil fertility.

DDisplacement of affected populations.

Answer:

C. Increased soil fertility.

Read Explanation:

  • Drought's Actual Impact on Soil: Drought generally reduces soil health and fertility over time by:

    • Slowing down nutrient cycling due to decreased microbial activity.

    • Reducing the stability of soil aggregates.

    • Making topsoils powdery and susceptible to erosion (which removes fertile topsoil).

    • Limiting nutrient uptake by plants due to lack of water.

  • Mentioned Cascades: The text explicitly states that a drought "may result in other disasters like food insecurity, famine, malnutrition, epidemics and displacement of populations." These are all negative consequences, whereas increased soil fertility would be a positive outcome.
