Given that Pakistan is predominantly arid and semi-arid, desertification leads to agricultural output losses, rising poverty, and significant drops in _________?
Show answer Hide answer
Answer: D. All of these
Explanation
Desertification degrades arid and semi-arid lands, destroying fragile natural ecosystems. Agricultural output losses and rising poverty accompany severe environmental degradation impacts. Biodiversity loss, reduced soil carbon, and climate change acceleration all result directly. Desertification is driven by overgrazing, deforestation, and changing climatic precipitation patterns. Vegetation loss exposes soils to wind and water erosion, removing vital organic carbon. Ecosystem disruption drastically reduces the number of native plant and animal species.
Combating desertification requires sustainable land management, reforestation, and water conservation. Global climate agreements emphasize preserving soil carbon storage to mitigate warming trends. Protecting biodiversity in drylands safeguards rural livelihoods and regional food security. Option A lists contributing to global warming, which is a major consequence of desertification. Option B mentions carbon storage reduction, another critical impact of degraded dryland soils. Option C highlights biodiversity loss, which also occurs extensively during desertification.
