Description Deforestation, overgrazing, and declining soil regeneration periods
have resulted in increased wind erosion problems in dry areas of th;
West African Sahel, but little is known about the bio-physical factors
involved. This research was conducted to determine the effects of
ridging and four different windbreak spacings on wind erosion, potential
evaporation, and soil water reserves. A field trial was conducted
from 1985 to 1987 on 12 ha of a Psammentic Paleustalf in
Southern Niger. Millet, Pennisetum glaucum (L.), and cowpea, Vigmi
unguiculata (L.) Walp., were seeded in strips on flat and ridged soil.
Windbreaks of savannah vegetation were spaced at 6, 20, 40, and 91)
m. The effects of ridging on wind speed, evaporation, and wind erosion
were small and mostly non-significant. However, average wind speed at 0.3 m above ground in the center of cowpea and millet strips
was significantly reduced from 2.8 to 2.1 m s"1 as windbreak distances
narrowed from 90 to 6 m.
