Sheet erosion from arable lands in Zimbabwe: prediction and control
IAHS Publication 144: 429-438
Rill and gully erosion on arable lands in Zimbabwe have been effectively controlled by mechanical conservation measures. However, rates of soil loss by sheet erosion of between 50 and 80 t ha-1 year-1 have been estimated. Forward projections indicate that this rate of soil loss will destroy the productive potential of large tracts of cropland within the next 30-50 years.
