  2. Which agricultural practice directly causes desertification by removing protective vegetation cover?

    • Crop rotation
    • Overgrazing
    • Drip irrigation
    • Contour ploughing
  3. Which natural climatic phenomenon contributes to desertification by significantly reducing soil moisture levels?

    • Prolonged drought
    • Thermal expansion
    • Flash flooding
    • Solar flare
  4. What direct ecological impact occurs when dryland soil loses water and key nutrients?

  8. What major socio-economic issue affects local human populations when agricultural drylands undergo desertification?

    • Food insecurity
    • Rapid industrialisation
    • Urban sprawl
    • Coastal flooding
  9. Desertification is primarily caused by the interaction of climate change with which general factor?

    • Human activity
    • Volcanic eruptions
    • Oceanic currents
    • Tectonic uplift
  10. Which predicted future climate trend will most increase desertification risk in drylands?

    • Decreased precipitation
    • Lower temperatures
    • Increased snowfall
    • Rising sea levels
  11. What process makes desertification function as a positive feedback loop?

    • Increased plant growth
    • Higher annual rainfall
    • Accelerated soil erosion
    • Rapid soil formation
  12. Which local adaptation strategy builds community resilience against growing desertification risks?

    • Intensive monoculture

    • Shelterbelts
    • Terracing
  19. What is the main direct effect of desertification on agricultural productivity?

    • Lower crop disease
    • Increased soil fertility
    • Reduced crop yields
    • Expanded arable land
  20. Why are rural dryland populations particularly vulnerable to desertification?

    • High industrial employment
    • Subsistence farming reliance
    • Diversified economy
    • Widespread urbanisation
