Desertification 1

1.      Desertification commonly occurs in __________ regions where annual rainfall is extremely low, making it difficult for most vegetation to survive and for agricultural activities to be sustainable.

• humid

• arid

• fertile

• reversible

1.      One major contributor to land __________ is unsustainable land management practices, such as deforestation, excessive farming, and the overuse of chemical fertilizers, which degrade the soil's natural structure.

• degradation

• geology

• migration

• irrigation

In many drought-prone regions, __________ of the land without crop rotation or fallow periods leads to nutrient exhaustion and rapid desertification.

• migration

• salinization

• overcultivation

• oasis

Q4. As the soil becomes increasingly __________ due to repeated crop failure and water scarcity, local farmers struggle to sustain any productive agricultural activities.

• arid

• fertile

• humid

• infertile

Q5. The loss of natural __________ is a significant indicator of environmental decline, often visible as large patches of exposed, barren land that can no longer support biodiversity

• irrigation

• salinity

• geology

• vegetation cover

Q6. Continuous __________ of the same type of crop on exhausted land without restoring soil nutrients eventually transforms fertile areas into desert-like landscapes

• migration

• salinization

• rotation

• overcultivation

Q7. The alarming __________ at which formerly green and fertile regions are turning into arid wastelands demonstrates the urgency of implementing global solutions to desertification

• swiftness

• border

• cultivate

• livestock

Q8. Pastoral communities in drylands depend heavily on their __________ for livelihood, which in turn puts pressure on fragile ecosystems and contributes to land degradation

• oasis

• geology

• livestock

• precipitation

Q9. Poor water management practices, such as excessive irrigation in dry areas, can lead to an increase in soil __________, further reducing its suitability for crops

•  famine
