The West African Sahel is the transition zone between the
Saharadesert in the north of Africa and the more humid Sudanian
zones in the south. Although diverse in many ways, the Sahelian
countries have the common problem of a fragile agricultural sector.
This predicament is mainly caused by low inherent soil fertility,
limited and unpredictable rainfall, frequent droughts, and wind
erosion that accelerates soil degradation and desertification,
compounded by To assure food production in the future, means
rapidly growing populations. of declining soil fertility and
increasing must be found to offset the trends soil degradation
through wind erosion. This is a challenge for agricultural
research. Since 1985, the Special Research Program 308 'Adapted
Farming in West Africa' at the UniversityofHohenheimin
collaboration with the International Crops Research Institute for
the Semi-Arid Tropics (ICRISAT) in Niger, has pursued the
developmentof agricultural innovations for smallholder farmers in
one of the most ecologically fragile regions of the world. The
prevention of soil degradation, the restoration and maintenance of
soil fertility, and the increase of land and labor productivity are
key objectives of this multidisci plinary research program. From
the beginning, a major focus of research has been wind erosion.
