In the Sahel, sandy soils are widespread and support not only most of pearl millet production, the major staple crop in the region, but also forage production for livestock. Parent sediments of these soils have an aeolian origin and hence are prone to wind erosion. However, the clay content, albeit very low, results in the formation of crusts during rainfall, thus leading to runoff and water erosion. Squall lines, major rainfall events of the rainy season, are usually preceded by intense wind.

A regional workshop was held in Ethiopia (Eastern Africa) to assess the status, future needs, and methodological issues of soil fertility research for bean cropping systems on the continent. Traditional forms of soil fertility maintenance, diagnosis of soil fertility constraints, nutrient requirements, use of fertilizers, cropping systems and soil fertility, and soil organic matter and the use of green manures and mulching were addressed.

Availability of rainfall time-series is limited in many parts of the World, and the continuity of such records is variable. This research endeavors to extend actual daily rainfall observations to ungauged areas, taking into account events of rainfall as well as cumulative total daily rainfall, over a period of 11 years. Results show that rainfall events histograms can be reconstructed, and that total cumulative rainfall is estimated with 85% accuracy, using a surrounding network of rain gauges at 30-50 Km of distance from the point of study.
