The present study aims at mapping some western Cameroon bauxites combining results of digital processing of satellite data (ETM+ of LandSat) with the geological, structural, mineralogical and geochemical characteristics of the Foumban area. Two categories of encrusted bauxitic surfaces have been ...

The use of enclosures has globally gained popularity as an effective strategy to enhance soil carbon sequestration, but empirical evidence is lacking particularly in arid and semi-arid rangelands of Africa. This study addressed the effectiveness of long-term (15–37 years old) enclosures in enhanc...

Unlike developed countries, where people often eat too many animal products, most of the population of Sub-Saharan Africa eats too little of this type of food for good nutrition. The projected increase in demand for livestock in sub-Saharan Africa will have an important influence on food security...

Annual estimates of production traits over a 22 year period (1965-1987) for Black Head Persian sheep (BHP) from Malya and West Kilimanjaro research centers in Tanzania were utilized to analyse variation of flock productivity over time. Principal component analysis was used to anlyse the variation...
