Negative
-Concrete pavements, roads create an impermeable layer that hinders infiltration.
-Deforestation through slashing and burning can reduce infiltration rates as plant roots promote and facilitate infiltration.
-Irrigation increase soil saturation preventing further infiltration (not quite a disadvantage though).
Positive
-Afforestation
-Flattening slopes and terracing reduces surface runoff which gives water enough time to infiltrate.
