MCQ (Single Correct) +4 −1

What is a potential disadvantage of agroforestry systems?

Increased soil erosion Decreased carbon sequestration Reduced biodiversity Enhanced susceptibility to pests Correct

Enhanced susceptibility to pests: In some agroforestry combinations, woody perennials can act as alternative, collateral, or over-wintering host plants for insect pests and fungal pathogens, potentially increasing pest pressure on adjacent companion crops. (Correct answer)
Soil erosion: Agroforestry systems significantly reduce water and wind erosion through protective tree canopy cover and root anchoring.
Carbon sequestration: Integrating woody trees with crops markedly enhances both aboveground biomass and soil organic carbon sequestration.
Biodiversity: Multi-strata agroforestry increases floral and faunal biodiversity by creating diverse micro-habitats.
