Answer
Deforestation reduces rainfall and groundwater recharge, causing lower river flow and increased soil erosion that reduces soil fertility.

Step-by-step solution

  1. Tree canopy intercepts rainfall and reduces evaporation, which helps maintain groundwater.
  2. When trees are cut, less water infiltrates, lowering groundwater recharge and river flow.
  3. Reduced evapotranspiration leads to lower rainfall over the region.
  4. Consequently, agricultural water availability decreases.
  5. Loss of trees increases soil erosion, removing fertile topsoil.
  6. Thus, two specific effects are: lower river flow and increased soil erosion causing loss of soil fertility.
Common mistake: Neglecting link between trees and rainfall

Concept tested: Impact of deforestation on hydrology
