What is desertification and its main drivers?

• A. The degradation of land in arid environments into desert-like conditions, driven by overgrazing, deforestation, drought, and poor water management
• B. The natural expansion of deserts due to climate cycles
• C. The process of reforestation in arid zones
• D. The conversion of desert into irrigated farmland

Answer: (A)

Desertification is the degradation of land in arid and semi-arid regions, turning productive land into desert-like conditions. It is driven mainly by overgrazing, deforestation, drought, and poor water management, because each factor reduces vegetation cover and weakens the land’s ability to hold soil and moisture. Overgrazing strips away protective grasses, leaving soil exposed to wind and water erosion and lowering soil fertility. Deforestation removes the tree roots and canopy that stabilize soil and regulate moisture, speeding up drying and erosion. Drought lowers soil moisture and slows plant recovery, so once degradation begins it can spiral without quick regrowth. Poor water management, including inefficient irrigation and salinization, degrades soil structure and salinity, further reducing productivity. These drivers often interact, making land less able to recover after dry periods. It isn’t just a natural expansion of deserts due to climate cycles, it isn’t reforestation, and it isn’t the conversion of desert into irrigated farmland.
